Bloomberg’s Matt Levine has a great article, published today, which begins with a discussion of the apparently-hollow shell company “Neuromama” (OTC: NERO), which — cue shocked face — is probably not in reality a $35 billion USD company, but quickly moves into a delightful discussion of insider trading, money market rates, an “underpants gnomes”-worthy business plan, and the dysfunction of the Commodity Futures Trading Commission. There’s even a bonus mention of Uber shares trading on the secondary market, which is something I’ve written about before. Definitely worth a read:

Heavy Ion Fusion and Insider Trading

If you only read one section of it, the part on “When is insider trading a crime?” is, in my humble opinion, probably the best. (Memo to self: next time there’s a big insider-trading scandal, be sure to come back to this.) But really, it’s a good article. Okay, there’s a bit too much gloating about those stupid regulators and their stupid regulations for someone who isn’t a hedge fund manager to get excited about, but it’s fucking Bloomberg, that’s probably a contractual obligation to get printed there. Also it’s Congress’ fault anyway, as usual.

It seems that the shine has started to wear off of the “giant unicorns”, the largest non-public tech startups with valuations over $1 billion USD. To the point where people are starting to wonder how, exactly, they could short Uber, that unicorn-among-unicorns (perhaps an ‘ubercorn’?).

It’s almost as if people are waking up to the idea that a company that doesn’t own any meaningful capital assets and whose success depends on an easily-duplicated strategy and a mobile app, and whose most recent business innovation is to get into sub-prime vehicle leasing, might not be worth more than BMW, Ford, or General Motors.

That’s not to say that Uber, or ride-sharing generally, is doomed. But the $62.5 billion USD present valuation seems absurd, and there are a significant number of flaming hoops that the company has to successfully jump through in order for common-share investors to get paid out at that level.

The $62.5B number implicitly assumes not just that Uber will continue to be successful as an urban ride-sharing taxi alternative, but that it will be an agent of radical, transformational change in global personal transport. Specifically, it seems to require that the dominant (and admittedly inefficient) model of personal automobile ownership pioneered in the US in the 20th century will collapse, and be replaced with fleets of time-shared robotic cars. Nothing else short of that would result in the $60+ billion valuation.

Taking a bet on autonomous vehicles is one thing, but putting all your chips on the assumption that the public will suddenly abandon its love affair with cars and begin behaving like rational economic actors is quite another.

Reading between the lines, it would seem that Uber’s leadership probably agrees at some level, and that’s why they’re so reluctant to IPO. If they were to go public today, their market cap would probably not be nearly the $60B figure, and individual employees and early-round investors would essentially wiped out due to late-round funding terms. So they’ve chosen to delay the IPO as long as they can, perhaps in the hope that all the long-shot bets will pay off by then. It’s a big gamble.

Uber, by prohibiting secondary sales of its pre-IPO shares, essentially prohibits straightforward short positions, making it a “one-way bet”: you can bet that they’ll succeed, but you can’t bet that they’ll fail — all you can do is not play. Since I don’t take short positions as a rule this doesn’t bother me, but it does further suggest that their valuation is somewhat bogus, and they know it.

My guess is that Uber isn’t going anywhere, but there’s going to be some very serious retrenchment in both their ambitions and in their total valuation in the next few years. I wouldn’t go out of my way to achieve a short position against them, but the lengths to which investors are going to get a piece of their action seems like a classic irrationally-exuberant bubble market.

I’ve been following the Mt. Gox security breach and subsequent Bitcoin/USD price collapse for a little while. This is a rough summary of events as they seem to have happened, based on available information at the current time (June 20, early morning UTC).

My assumption is that at least some of this timeline will turn out to be wrong, which in itself might be interesting in retrospect.

Sometime in early June: Unspecified attackers gained access to a machine, allegedly being used by an auditor, either containing or with read-only access to, the Mt. Gox database or some portion of it. Whether the attackers had access to the entire database or “just” the user table doesn’t seem known, but the important thing is that they got a table containing, according to Mt. Gox:

  • Account number
  • Account login
  • Email address
  • Encrypted password

For accounts not accessed in the last two months (viewed by Mt. Gox as “inactive”), the password was stored as an MD5 hash. For accounts accessed in the last two months, the password was salted, then hashed with MD5. Nowhere in the database were there plaintext passwords.

Exactly who had access to the database, whether it was an individual or group, isn’t known. It seems that access to the database might have gone through several stages: presumably from the person or group who obtained it initially from the compromised machine, and then to less-sophisticated people or groups. We can say with some confidence that it started to be distributed shortly before June 17th, because on that date somebody posted a message to a forum with some hashed passwords that came from the database. (N.B., this is hearsay from the #Bitcoin IRC channel, and thus fairly speculative. I haven’t looked at a copy of the database to confirm it.)

Monday, June 13: The actual theft of Bitcoins from compromised accounts began, according to various sources, on Monday morning. Approximately 25k BTC were transferred from 478 accounts, according to DailyTech (although elsewhere in the same article they claim 25,000 accounts). The destination address was “1KPTdMb6p7H3YCwsyFqrEmKGmsHqe1Q3jg”.

Presumably, the accounts were accessed by brute-forcing the hashed passwords in the database. It’s not clear to me whether the accounts were all “inactive” (and thus had unsalted password hashes, vulnerable to a pre-computation attack), or if they were active, had salted hashes, but were just weak and fell to a dictionary attack. It probably would have been logical for the attackers to pursue both routes at once: go after the old, unsalted hashes with Rainbow tables, while at the same time performing dictionary attacks against the salted hashes associated with accounts with significant BTC balances. At any rate, using some combination of both routes, they eventually found some vulnerable accounts.

The thefts seem to have gone on during the remainder of the week, with Mt. Gox seemingly misreading the increase in theft reports as insecurity on users’ PCs, rather than a security problem on their end.

Sunday, June 19: The Bitcoin ‘Flash Crash’.

At around 3AM Japan Standard Time, someone — my guess is not one of the original attackers — began a massive sell-off from a single compromised account. (One open question is whether this account was a receiver account for stolen BTC from other hacked accounts, or just happened to be a ‘whale’ that they managed to access.) This is where things start to get interesting, because it’s not immediately obvious why someone who recently came into possession of a whole lot of Bitcoins would want to crash the price.

One theory is that it wasn’t intentional; they were hurrying, perhaps working against other attackers who had access to the same database, and wanted to cash out quickly. But another theory, one that I think is more plausible, is that the sell-off was calculated to crash the BTC price, in order to get around Mt. Gox’s $1,000 USD/day withdrawal limit.

By dumping a large number of Bitcoins onto the market — not just once but twice (the attacker repurchased and sold the lot of coins a second time, supposedly) — the market price was driven down. Basically all open bids on the order book were filled, down to ridiculously low prices. At no point did any sort of ‘safety switch’ kick in at Mt. Gox to halt trading; it was full-bore Black Monday mode.

And here we start to run into my limit of knowledge. If we assume that the crash was engineered in order to get around the Mt. Gox withdrawal limit, then when the price was very low, the attackers should have made their move, and transferred whatever they could out of Mt. Gox, to external Bitcoin accounts.

Mt. Gox seems to be claiming that this did not happen, and the withdrawal limits successfully kept the total amount of BTC removed from the exchange to some low number. If true, this would allow them to ‘reset’ the exchange back to how it was before the flash crash, with only limited losses — perhaps low enough that Mt. Gox could make all users whole before resuming trading.

But if this isn’t the case, then it may not be possible for Mt. Gox to shield all of its users from losses. After all, one of the key features of Bitcoins is that they can’t simply be magic-ed into existence on demand by a central authority when convenient. If the Bitcoins have left the building, so to speak, Mt. Gox can’t just grab them back or create new ones to replace them.

In the next few hours or days, I expect these issues to become more clear. Also, it will be interesting to see whether the BTC/USD rate stays at the $17 mark that Mt. Gox plans to resume trading at, or immediately falls to some lower level, in keeping with lowered investor confidence.

Personally, I wouldn’t mind one bit if this marked the end of Bitcoin’s first speculative bubble; most of my interest in Bitcoin is as a currency, not as an instrument for speculative investment (and a not-very-liquid one at that). The question will be whether Bitcoin’s reputation is irretrievably damaged as a result, or if the damage is forgotten about or limited to Mt. Gox.

Certainly more interesting and higher stakes than the usual EVE Online drama, though.

As is perhaps evident from some of my other posts, I’m kind of a sucker for alternative currencies. A couple of years ago I watched the trainwreck that was the demise of 1MDC, a ‘currency’ that was backed by EGold (which was itself shut down in 2009). And then there’s the sad saga of the Liberty Dollar, which in retrospect probably would have avoided a lot of legal trouble if it had been called the ‘Liberty Peso’ or something a bit less official.

Liberty Dollars and EGold (and its spawn, e.g. 1MDC) were, until recently, arguably the high-water marks for private currencies in the U.S., in modern times anyway. However, both of them suffered crucial flaws: they were built around centralized institutions which created single points of failure. When they eventually aroused the attentions of the authorities — as any private currency is likely to do — they were pretty quickly taken down.

In the case of someone holding physical Liberty Dollars this wasn’t really catastrophic, since they still had the coins. (Even morons who bought them at terribly inflated prices might have come out ahead, due to the run-up in commodities prices in the last few years, if they held out long enough.) However, “holders” of EGold were right out; they had to wait until mid-2010 to be able to get their money out, and then only by identifying themselves.

One would not have been faulted for thinking that the idea of private currencies, existing in parallel to government-backed ones, was finished.

But it’s instructive to consider why EGold was designed the way it was, with a centralized architecture. If we give its developers any benefit of the doubt at all, they must have realized this was a gaping vulnerability. But it was a necessity for two reasons:

  1. They wanted to back their currency with a physical commodity, namely gold.

  2. They wanted to be able to make money on it.

The point I’m (rather laboriously) making my way around to, is that neither of these are true for all private currencies, and Bitcoin in particular seems to avoid them.

Bitcoins aren’t backed by anything. Unlike EGold and Liberty Dollars, both backed (either directly or indirectly) by gold, Bitcoins aren’t backed by anything. They have exactly zero intrinsic value. While that makes them rather volatile, it also means there’s no warehouse full of metal to be inconveniently seized.

Second, there doesn’t seem to be much in the way of a profit motive behind Bitcoin’s development. Both Liberty Dollar and EGold seem, on their face, to be money-making ventures for those behind them. Liberty Dollars were sold, at a premium above their intrinsic value, by NORFED; EGold charged management fees, presumably in excess of its costs to have some gold bars stored in a vault. PayPal, which is admittedly not a private currency, makes money via transaction fees. All of those models require a centralized architecture in order to generate revenue.

Bitcoin’s architecture eliminates the potential for a Bitcoin, Inc. IPO, but in doing so it is significantly more difficult to shut down.

One area where Bitcoin seems to remain vulnerable is in its convertibility to traditional currencies, especially USD. Although it’s possible in theory to ‘bootstrap’ a currency (particularly one with a fixed number of tokens) that’s not convertible — someone would need to jump in and start pricing goods in it, and in doing so imbue the currency with real-world value — but it’s certainly a lot easier if you can move value back and forth from other currencies.

Currently there are several public Bitcoin markets, including Mt. Gox, the largest, Bitcoin Exchange, which is a forum for person-to-person transactions, and BitcoinExchange.cc, which just strikes me as shady (maybe it’s the .cc TLD).

Even at Mt. Gox, buying Bitcoins is not a straightforward process. You can’t just whip out your Visa and buy $100 worth of Bitcoins at the going rate; instead, you have to go through one of several intermediaries who handle the USD side of the transaction, moving money into a Mt. Gox account, and then you can use the money to buy Bitcoins. It’s not that much worse than setting up an account with a brokerage (and the fees and minimums are much lower!), but it’s not like the Foreign Exchange desk at the airport.

This is where I’m a bit concerned that the whole Bitcoin concept could get in trouble. Right now, the value of Bitcoins — which are backed by nothing, other than a mathematical guarantee that only a certain number can be ‘minted’ — has built into it an assumption about the ease of converting them into USD and other currencies. If the ability to convert Bitcoins to USD or other currencies was suddenly suspended, I suspect you would see a very sharp drop in the value of Bitcoins. In doing so, it might erode confidence enough to render it useless or insignificant as a currency.

Exactly how this plays out will be very interesting in the months and years ahead. The U.S. government took significant amounts of time to bring the axe down on EGold and Liberty Dollars, so the lack of immediate action shouldn’t be taken to indicate any change in attitude towards private currencies. If and when something does happen, my bet is that it occurs at the BTC/USD/EUR/etc. exchange points. We’ll see.

Peter Thiel, formerly of PayPal, more recently of the Founders Fund and Clarium Capital, has an interesting article in the Hoover Institution Policy Review, called “The Optimistic Thought Experiment.” The best one-sentence summary is probably his own: “In the long run, there are no good bets against globalization.”

However, the article is more interesting than just that, and even if you disagree with that particular conclusion — perhaps especially if you disagree with that particular conclusion — it’s worth a read.

The argument that I found most interesting is that, as a result of more powerful technologies and a more complex and interconnected world, a greater risk exists of “secular apocalypse,” a complete, system-wide failure of the current capitalist framework, than has ever existed in the past. What might have been local panics or crashes now reverberate globally, even as new failure modes have emerged.

This, in particular, struck me:

[T]he extreme valuations of recent times may be an indirect measure of the narrowness of the path set before us. Thus, to take but one recent example, in 1999 investors would not have risked as much on internet stocks if they still believed that there might be a future anywhere else. […] It is often claimed that the mass delusion reached its peak in March 2000; but what if the opposite also were true, and this was in certain respects a peak of clarity? Perhaps with unprecedented clarity, at the market’s peak investors and employees could see the farthest: They perceived that in the long run the Old Economy was surely doomed and believed that the New Economy, no matter what the risks, represented the only chance. Eventually, their hopes shifted elsewhere, to housing or China or hedge funds — but the unarticulated sense of anxiety has remained.

I am not sure exactly how convinced I am of this — it has a sort of exceptionalist tinge to it that I am intrinsically skeptical of — but it’s a very interesting theory. To some extent, casual observation bears it out: the last few years, we have seen speculative bubbles pop up in various places as investors have moved from one market to the next in search of returns.

Much has been made of the fact that some of these bubbles — real estate in particular — just never made a whole lot of sense, or at least not enough sense to justify the amount of money that was being pumped into them, or the fervor with which it was being pumped, not just by I-banks and hedge funds, but by individuals ‘flipping’ houses, taking on second homes, and getting involved in shady high-return investment schemes (which are still being advertised on sketchy hand-drawn yard signs at major intersections in my area).

Viewed through the lens of Thiel’s thought experiment’s premise, it starts to look a whole lot less irrational and a whole lot more rational — albeit desperate.

It also made me wonder about the long-standing arguments regarding the ‘equity premium’ (the premium paid by equities versus ‘risk-free’ investments like Treasuries). Some people argue, generally by analyzing U.S. market returns during the 20th century, that the equity premium is around 5-8%. However, others suggest that in the future, it might be more like 3-4% over cash. The jury is definitely still out on this, but it certainly seems like there is a developing consensus that the equity premium is in decline.

The equity premium has long been considered something of a mystery, because it’s higher than you’d expect given investor behavior. With an equity premium of 7% over bonds, you’d have to be almost ridiculously risk-averse to not buy equities. But if the premium is as low as some suggest it may be going forward, than the mystery might be the other way around: why hold equities when you can have less risky bonds instead, at a small discount?

My completely speculative theory is that perhaps this is due, in part, to the kind of attitude Thiel discusses. If investors suspect, consciously or unconsciously, that a scenario in which their S&P 500 fund becomes worthless would also be one where T-Bills or even cash are worthless (or, less extreme, that they’d lose significant value as well), then they might not agree that the difference in risk is great enough to justify the lower yield of the ‘safer’ investment.

Of course, the market could just be irrational. I’m not sure that anything other than time is going to tell.

Calculated Risk, one of my favorite finance and economics blogs, has a great article written by the late Tanta on The Psychology of Short Sales. The piece really hit home for me, because during my recent search for new quarters, I ended up drooling over a lot of short sale listings, only to be warned by my agent that they often take a very long time to execute and frequently fall through. I quickly cooled to the concept.

On paper, short sales are the ultimate win/win for an upside-down homeowner who wants to “walk away,” and a lender who wants to minimize their loss. It lets both parties avoid foreclosure, prevents a house from sitting empty and potentially becoming a target for vandalism, squatters, and generally a source of neighborhood blight, and lets the homeowner remain on the property and leave gracefully when it sells. Plus, potential buyers get a house that hasn’t been trashed by a bitter ex-owner, or had its pipes freeze and burst due to over-winter neglect. Triple win, right?

That’s on paper. In practice, things often don’t work out so well. Because of the way short sales work, there’s often a disconnect between what the various parties involved in the deal think the property is worth. If they can’t reconcile their views, there’s no sale and the property goes back on the market, and eventually to foreclosure.

The biggest difference between a short sale and a traditional bank-owned post-foreclosure property (a “REO”, or “real estate owned”) is that in the latter case, the bank has already taken possession of the property, probably had it assessed, and accepted that they’re going to take a non-negligible loss. It’s just a non-performing asset sitting on their books at this point, one that they’d presumably like to unload at the earliest possible opportunity at an acceptable price. Contrast this to a short sale: the bank has just learned that the current homeowner can’t make their payments and wants out, and has responded by telling them to get a listing agent and put it on the market. They haven’t really written anything down yet. The big loss is still to come.

To a buyer, a short sale property ought to be more attractive than a REO, because it hasn’t been sitting vacant or gotten trashed during a ugly eviction. However, buyers quickly learn to beware these six words in any listing: “offers subject to third-party approval.”

When a buyer makes an offer on a REO, the offer goes to the bank and they get a pretty straightforward thumbs-up or thumbs-down. Either the offer is acceptable and it sells, or it isn’t and the bank is content to let it stay on the market a bit longer. Since the bank already owns the house, they just want to get the most for it they can.

When an offer is made on a short-sale property, it gets forwarded by the listing agent to the bank, who has the choice of whether to accept it or not. If they accept it, they’re almost certainly taking a loss and accepting a writedown on the original mortgage. There is a big psychological difference between this and the REO case, it seems to me: in a REO situation, the bank is trying to recoup as much as it can of an already-realized loss; in a short-sale, the bank is actually taking the loss as part of accepting the offer.

This psychological difference seems to manifest itself in the relative speed with which banks process the two different types of offers. REO offers get decisions rendered quickly; short sale offers can take months to process, during which both the buyer and seller live in uncertainty. This uncertainty causes buyers to make fewer offers on short sales than on REOs, and to offer less for short sales than they might otherwise. In theory there’s no reason why short sales should sell for much below what a regular owner/buyer sale would, but in practice they go for something closer to REO prices. This difference is, to my eyes anyway, almost completely due to the perceived arduousness of the short sale process.

In addition, there’s often a failure on the part of buyers and lenders to understand how the short sale benefits the other party, and how this affects the price they’re willing to accept. This is what Tanta explores in the Calculated Risk article. Lenders are only interested in a short sale if it results in a price that’s significantly (more than 40%) greater than what the property would fetch as a REO, post-foreclosure. Buyers, on the other hand, often try to bid less than what the property would fetch as a REO, on the assumption that the lender ought to be willing to take a little less on a short sale than they would as a REO, since they’re avoiding going through foreclosure. Hence, no deal.

In order to make short sales a more viable option for distressed homeowners who find themselves upside-down on their mortgages and unable to pay for them (or who simply want out and can’t sell normally and cover the mortgage), I can think of several things that need to happen:

  • Banks and other lenders need to assign more staff to “special assets” and other pre-foreclosure divisions, and realize that they can avoid needless trouble and expense by going the short-sale route versus foreclosure. They need to gear these divisions to providing fast up-or-down decisions on short sale offers, and empower employees to write down assets significantly (at least as much as the delta between the REO price and the loan face value) in order to make deals happen quickly.

  • Prospective buyers need to be better-educated about how short sales work, not only from their own perspective, but also from the owner’s and lender’s. They need to understand why a lowball, sub-REO offer isn’t going to fly with the lender. For a short sale to work, three parties — the owner, the buyer, and the lender — need to feel like they’re making out better than they would have via foreclosure. Offering substantially less than a property would fetch as a REO doesn’t allow that to happen.

  • Homeowners considering a short-sale, whether in financial distress or not, need to be better about selling their properties. They need to work hard to make it clear to buyers that they’re not selling a REO, and that the property is inhabited and well-maintained. If a house looks like a foreclosure property, it’s going to get offers that reflect that, and it will almost certainly end up as a foreclosure property eventually. I saw several short-sale properties during my recent search that were frankly worse than the average REO, and that just isn’t going to work.

As it turned out, I didn’t make any offers on the short sale properties that I looked at. Given the time available before I have to be out of my current rental, it just doesn’t make sense. And I definitely wasn’t alone: many short sale properties had been on the market for hundreds of days, while REOs are being snapped up almost daily by hungry buyers armed with low rate pre-approval letters.

Making the reality of short sales better match the concept would provide affordable homeownership to many buyers, a dignified ‘out’ for distressed owners, and smaller losses to lenders and their investors. But a lot has to happen before that will be the case.

Steve Waldman has a good article over on Seeking Alpha about the difference between “transactional” and “revolving” credit. As we are in the middle of what is often described as a ‘credit crisis,’ understanding the difference between these two products is fairly important, as each have quite different benefits and hazards and create different policy implications.

I got a letter from BB&T last week, an actual paper letter, on account of owning a couple of shares of their stock. I had already heard the news that they planned to cut their dividend and issue between $1.5 and $1.7 billion in new stock to get out of TARP, but struck me as interesting that they bothered to send out notices, in the form of a letter from the CEO, to all shareholders of record.

The letter is available online here (PDF).

Most news coverage of BB&T’s decision to repay TARP has focused on the dividend reduction, and a remark by CEO Kelly King that it “marks the worst day in my 37 year career.” However, I thought the second page of the letter was really the most interesting:

Many of you have asked why we agreed to participate in the Capital Purchase Program last November. Frankly, we did not need or want the investment, but our regulators urged us along with other healthy banks to participate for the purpose of increasing lending to improve economic conditions.

Them’s fighting words right there, or at least they are by the admittedly low standards of a corporate shareholder communique. For a few months now, rumors have been circulating that healthy banks — like BB&T — were essentially forced or otherwise pressured by regulators to participate in TARP, in order to make it seem less like the plague ward than it really was. This is the first written confirmation that I’ve seen from senior management at a ‘healthy’ bank basically confirming the worst of those rumors.

The key word is that executives at BB&T didn’t “want” the TARP money from the beginning, indicating they must have been pressured or coerced — given ‘an offer they could not refuse,’ perhaps — to take it anyway. The letter doesn’t get into exactly what form that coercion took, but I suspect in time more details, beyond what are already known, will come out. Doubtless it won’t look all good for the banks when it does; in the end all the majors caved, and when they complain Treasury will accuse them of hypocrisy: buying into the plan when the going was tough, but getting buyers’ remorse now that things are looking somewhat better. This is a legitimate accusation that they’ll have to work hard to defend against. The ultimate question will be what the consequences of not participating — essentially calling the Don’s bluff — would have been, and whether they would have been preferable to what actually occurred.

The government, it seems, is going to turn a fair profit on TARP at great expense to the investors in healthy banks. (The sick banks won’t really have lost money to TARP, at least not in the same way that banks like BB&T did, because they actually needed the capital infusion to stay alive; for them it was money well spent.) I think it’s too much to expect at this point that anything will happen to recoup any of BB&T’s TARP-related losses, either the direct ones in the form of interest payments to the government, or indirect ones like the reduced dividend (which arguably they might have to have done anyway, but perhaps not — now we’ll never know) and share dilution.

There’s not much of a silver lining, but hopefully it will prove to be a ‘learning experience,’ albeit an expensive one. After having been so painfully screwed, it’s doubtful that BB&T or any of the other ‘healthy’ banks will have anything to do with similar programs to TARP in the future; whatever coercion was required to buy their participation this time around, next time they will almost certainly be tougher sales.

TARP may not have injected needed capital into the healthy banks, but it may have given them something far more important in the long run: backbone.

When I was in perhaps 5th or 6th grade, I recall my math teacher making a halfhearted effort to get us to play The Stock Market Game as part of our curriculum. It didn’t go very well and certainly wasn’t effective as a teaching tool; I remember a couple of class periods spent pretending to make sense of the NY Times’ stock pages while actually reading the comics, and very little else.

A few years ago when I first decided to play my own little stock market game with some Excel spreadsheets, and found myself learning a whole lot more about economics and the market than I had ever really intended, I wondered why I’d never done it before. And then the memory of that abortive attempt to do exactly that came back.

It strikes me as a rather sadly missed opportunity. Until I started playing with my little virtual portfolio in Excel, I had only a very vague idea of how the equities markets worked — and this is despite having taken the two semesters of required Economics in college. Would I have picked a different major or career path as a result of getting that little bit of fundamental understanding that you gain from playing with a paper portfolio earlier? (And would that have been a good thing?) I have no idea. And really, that question doesn’t interest me that much; I have no regrets, certainly, about my actual choices with regards to education or employment.

What does interest me is trying to figure out why, despite someone’s intentions that we would use the Stock Market Game in our math class, it never ended up amounting to anything.

The first problem, I suspect, is that my poor old math teacher — who had been teaching from the same curriculum for probably 30 years — didn’t know that much more about the stock market than we the students did. (I also suspect that she wasn’t the one to decide to include it in class; it just doesn’t, and didn’t at the time, seem like her style.) That combination was deadly, right off the bat. Whatever educational utility a virtual portfolio game might have — and people are rightly skeptical of them at times — it evaporates instantly when the teacher isn’t knowledgeable and interested in it themselves.

Perhaps the root of this problem was making it part of a math class in the first place. There really isn’t that much ‘math’ involved in maintaining a paper portfolio, and what there is represents pretty basic stuff — if you’re using a stock market game to teach percents, chances are you’re not really getting into what makes the stock market interesting and important; you might as well just stick to lemonade stand examples and save students the confusion.

The stock market game would probably have fit better into the history or social-studies curriculum than into math. That might have also caused the focus of the overall lesson to be more about the equities markets themselves — how they work, why they exist, what the effects are of market fluctuations — rather than simply on generating a short-term return in a virtual portfolio. (That would also go a long way towards addressing most of the criticisms of stock market games as propaganda tools expressed in the article by Maier, which are in my opinion mostly quite valid.)

The second major problem had to do with how the game itself was executed; this being the pre-Internet era, we did everything on paper and got pricing information out of the newspaper. Hopefully this wouldn’t be a problem today; it would be simple to use Google Finance, or even the Excel sheets I played with a few years ago, to do it now, and you’d at least get pretty graphs out of the bargain.

The only benefit I can attest to as a result of having to once try to use, or at least look at, the printed financials pages, is a vast appreciation for the electronic tools that are available today to the individual investor, or even to the merely curious. From the looks of the photos on TSMG’s website, they have changed with the times. (Damn kids will just take them for granted. Get off my lawn.)

Aside from simply replacing graph paper and the Times financial section with some pretty electronic system, bringing in computers also allows for a lot more research than would have previously been possible in a classroom setting. Research and due diligence are a huge component of investing and non-technical speculation, and that’s a lesson that you don’t need to become a stock broker or day trader later on in life in order to appreciate — anyone with a 401k will do.

I think the concept of a stock market game is a pretty sound one, in terms of teaching students about a fundamental and important part of our economy — one which can, as recent events have made plain, affect their lives whether they pay attention to it or not. I can only hope that how that concept is being executed today is better than the pathetic attempt I experienced many years ago.

Roubini Global Economics (RGE) has an interesting article called “Can China Adjust to the US Adjustment” that discusses, among other things, the relationship between foreign trade and the current credit ‘crunch.’ It’s a fascinating article both because of the interesting history it describes, and some of the predictions it makes.

Although we can’t say for sure, it is probably safe to argue that US savings rates will climb back to earlier average levels, or even temporarily exceed those levels, as American households rebuild their shattered balance sheets. If they return only to the mid-point of earlier savings rates, this implies that US household savings must rise by some amount equal to roughly 5% of US GDP, or, to put it another way, that all other things being equal US household consumption must decline by that amount.

Although it may just be that I haven’t been paying close enough attention, this is the first time I’ve seen anyone toss out a hard number estimate of how much they expect consumption to fall by. Pretty much everyone expects consumption to fall by some amount, but ‘how much’ is the real issue.

This decline — whatever it ends up being — will inevitably cause a decrease in China-to-U.S. imports, and that will have to be compensated by either an increase in domestic Chinese consumption, or a decrease in production. The article suggests, and I agree, that the former is highly unlikely. Although Chinese household spending is on the rise, there is just no way that it will rise fast enough or high enough to maintain the insane level of consumption that was until recently being bankrolled by the U.S. Hence, production there must fall.

Of course, falling production means factory closures and job loss, and that means domestic consumption will fall yet further, leading to a nasty downward spiral. The parallels drawn in the article between 1929 in the U.S. and 2008 in China seem pretty well-grounded; except, of course, that in 2008 Chinese regulators have volumes of economic theory and analysis written about 1929 at their disposal, if they choose to make use of it.
