Jon Hilsenrath, Damian Paletta and Aaron Lucchetti, "Goldman, Morgan Scrap Wall Street Model: End of Traditional Investment Banking," The Wall Street Journal, Sept. 22, 2008:
The most fundamental problem is how to generate profit growth in a world that no longer tolerates high leverage.

In a credit crisis, the "lender of last" will weigh options, now having to balance the desire to provide liquidity versus its desire to ensure market dynamics ("Credit Crisis Strains Government's Options," WSJ, Sept. 12, 2008):
Officials are also acutely aware of the problem of "moral hazard." Bailing out too many firms, the reasoning goes, would encourage more risk taking in the future. That makes officials reluctant to be seen as rescuing another institution. The Fed made a $29 billion loan to help J.P. Morgan take over Bear Stearns. It's not clear that it would be willing to do that for another firm.
Treasury Secretary Henry Paulson has said that institutions must be allowed to fail and that markets can't expect the government to lend money or support every time there's a crisis. "For market discipline to constrain risk effectively, financial institutions must be allowed to fail," Mr. Paulson said in a speech in July.

Josh White of The Washington Post summarizes the findings of "The Hidden Costs of the Iraq War," a report issued by the Democratic staff of U.S. Congress's Joint Economic Committee. I do not believe the cost analysis takes account of the immeasurable human toll involved.
If, instead of a dogged focus on imperial goals powered by fear, people demanded that this money be spent, prudently, on making U.S. economy more competitive, i.e. if they demanded that government-driven investments be focused on people, institutions, facilities and technologies that help people get on with their lives, work and play, the U.S. would not be facing the economic problems it is facing now and will be in a much better economic, political and social position globally.

I subscribe to two papers that are delivered every morning at my doorstep: The Wall Street Journal and Financial Times.
For three days now, Financial Times has carried stories and pictures of a bank run in the UK, involving Northern Rock, a financial institution focused on savings and loans geared to the mortgage market. (Some have argued that if there's only a single bank run, we do not have a bank run. However, financial crisis have their own way of diffusing to neighbors.) This morning, FT carries, above the fold, a 1/4 page picture of a crowd waiting to withdraw their savings from a Northern Rock branch.
No two industrial economies or countries are as intertwined as the UK and the US. Yet, if you read The Wall Street Journal this morning, you would hardly notice anything going amiss in the UK. On the front page, the news of the bank run is reflected only in a two-sentence paragraph falling on the fold, making it hardly visible, with a jump to page 3 of section C ("Money & Investing"), a section which bills an educational piece on yield curves on top of its own fold. On page C3, two short columns summarize the least salient parts of story, with no mention of a bank run.
I should end this by noting that the electronic version of FT, accessible here in California, has no images like the ones in the print edition on its front "page" today. However, one can find relevant images on Flickr -- like the one I've posted here.

Princes, abbots, bishops, even the Holy Roman Emperor debased the subsidiary coinage used in daily transactions (but not gold and silver coin of large denominations) by raising the denomination of existing monies, substituting baser for good metal, or reducing its weight, in order to extract more seignorage in the absence of effective tax systems and capital markets--this to prepare for the Thirty Years' War, which broke out in 1618. Debasement was limited at first to one's own territory. It was then found that one could do better by taking bad coins across the border of neighboring principalities and exchanging them for good with ignorant common people, bringing back the good coins and debasing them again. The territorial unit on which the original injury had been inflicted would debase its own coins in defense and turn to other neighbors to make good its losses and build its war chest. More and more mints were established. Debasement accelerated in hyper-fashion until a halt was called after the subsidiary coins became practically worthless, and children played with them in the street, much as recounted in Leo Tolstoy's short story, "Ivan the Fool."

Chartered Financial Analyst (CFA) designation has become a license to work in financial services anywhere in the world. Its appeal goes global with the globalization of financial services.
More people will sit for the CFA exam in Asia than in the US this year, some 52,900 as compared to 45,400, Financial Times reports this morning. CFA examinations began in 1963. Originally for analysts, it has become popular with asset managers and traders. Only half the candidates have traditionally passed the test. The rest "dop out during the course, which typically lasts four years.

Not only subprime lenders but also most other lending institutions package and sell their mortgage loans to investment banks who often slice and dice these loan pools to issue mortgage-backed securities of varying risk levels. Occasionally, as HSBC seems to have done with some loans, the bank may keep these loans on its own books. This is a very risky proposition. However as was also the case with subprime loans purchased by HSBC, most investment banks purchasing these loans include repurchase clauses in the mortgage pool contracts. After adding $1.76b to bad debt costs, HSBC has sued some subprime banks who have failed to abide with repurchase clauses. (See "Mortgage Hot Potatoes: Banks Try to Return High-Risk Loans To the Originators," The Wall Street Journal, Thursday, February 15, 2007. page A4.)
In economics, such repurchase clauses are called transaction "safeguards," which if set correctly, will lead to a better hybrid transaction model. They discourage subprime lenders to take unreasonable risks and put them in a risky position if they do take extreme risks. The investment bank purchasing the loan pool may at any time (coinciding with a trigger, perhaps) want to exercise the repurchase option.

So, has Mr. AI any advantages (other than speed, which may cause some self-defeating dynamic instabilities) in comparison to Mr. Market when it comes to voting for stocks? Or will it be any better than a good investor when it comes to weighting the value of stocks?
In general, Mr. Market represents the leveled investing masses roaming the market. There is nothing they do that has any special upside. The good, contrarian investor takes care to stand judiciously apart from such masses.
A given AI algorithm can hardly be said to be any better than any other (composed with the same level of parametrization). If anything, a large number of these algorithm, including neural networks, Baysian belief nets, Markov models, Guassian classifiers, fuzzy ones, etc., are intelligence-equivalent for most practical purposes. Their marginal advantages (in speed and parametrization) when used for leverage can amplify value impact of common investment risks and "errors" just as they may find interesting points in the market for leverage.
So, in the final analysis, while Mr. AI may even choose random rules for analzsis, it will most probablz remain an unrully side-kick of the good investor.

In his Wall Street Journal "Portals" column ("The Dot-Com Bubble Is Reconsidered," Nov. 8, 2006), Lee Gomes points us to an archeological study of the Internet bubble, some of whose findings contrast with conventional wisdom regarding the boom which is "normally dated from the Netscape IPO in August 1995 to March 2000, when Nasdaq peaked at above 5100":
A recent paper suggests that rather than having too many entrants, the period of the Web bubble may have had too few; at least, too few of the right kind. And while most people recall the colossal flops of the period (Webvan, pets.com, etoys and the rest) the survival rates of the era's companies turns out to be on a par, if not slightly higher, than those in several other major industries in their formative years.
The paper is being published in a coming issue of the Journal of Financial Economics. As noteworthy as the findings are, even more interesting is the process that led to them. The work is an outgrowth of the Business Plan Archive at the University of Maryland. Its goal is to become a kind of Smithsonian Institution of the Internet bubble, saving for posterity every business plan, PowerPoint presentation and venture-capital term sheet -- the more frothy and half-baked, the better -- that it can get its hands on.
