Yesterday's Market Excitement

In case, you haven't heard, the U.S. stock market was down big time yesterday.  The Dow Jones Industrial average dropped 634.76 points, or 5.5%.  This had something to do with Standard & Poor's downgrade of the U.S.'s credit rating from AAA to AA+ on Friday evening, but exactly how much is an open question.  The Wall Street Journal's front page headline this morning was: Downgrade Ignites a Global Selloff, but the unavoidable irony is that prices of Treasury bonds were up yesterday (yield on the 10-year note, which moves inversely to price, was down to 2.339%, its lowest rate since January 2009).  And repo markets, the main wholesale funding market by which Wall Street banks lend each other money using U.S. securities as collateral, were largely unaffected.

The sell-off seemed to be caused by a general flight from risky assets into safer ones, such as U.S. treasuries, gold and Swiss Francs, which in the past has been the result of fear of a double-dip recession and default and contagion in Europe.  Perhaps the downgrade just added an extra element of panic to the equation.  Or perhaps large market participants were afraid that the downgrade would cause politicians to do something stupid in reaction to what should be a non-event, what philosophers call an epi-phenomenon, like the smoke from a passing train, or the after-the-fact commentary by a sportscaster.  President Obama's speech certainly did nothing to stem the downturn.

Based on the Wilshire 5000 Total Index, which represents the total value of the U.S. stock market, the market has lost about $2.6 trillion since late July.  Unless you are an S&P sovereign debt analyst, this is quite a chunk of change--about $8,500 for each man, woman and child in the U.S.

Certain stocks were especially hard-hit in yesterday's sell-off: Bank of America and Citi were both down over 15%.  I lost quite a bit on the latter, not to mention Caterpillar, a Germany ETF and others.  Despite stern warnings from CNBC commentators --like lifeguards at Jones Beach--  that it is extremely risky for individuals to trade in such market conditions, I nibbled, and bought a bit more Citi at its new marked-down price.  Of course it dropped as soon as I bought it.  This morning, I saw that Citi was trading at less than half of its book value, and bought some more, using up the bulk of my available cash.   As of this writing, Citi is back up 12% on the day, so maybe I made a good decision -- for now.
