Does today's record 936 point rally in the Dow mean that happy days are here again? I think it's a gift to investors who want to stop their losses after having seen their portfolios plummet in the last year. Last week, the Dow fell 22%, destroying $2.4 trillion in market value -- it gained back $940 billion of that today. As an unpleasant reminder, after today's 11% rally, the S&P 500 has lost 36% of its value in the last year. And, while I hope I am wrong, I don't see the conditions yet in place to believe that we have reached bottom with the economy and can now expect the earnings growth that would justify investment in stocks

Today's rally feels good but it is highly likely that there was an element of short covering driving up the market. Last Wednesday, the SEC lifted its ban on short selling. Investors who shorted financial and insurance companies were doing quite well last week as fears of another financial bankruptcy mounted. With today's successful save of Morgan Stanley (NYSE: MS), anyone who was short that firm -- or other financial stocks -- was forced to buy those stocks as they spiked in order to repay their stock loans. This probably contributed significantly to a buying panic.

If you need your money in the next six years, you could sell first thing tomorrow morning and you will be able to limit the losses that could come from unpleasant surprises. What kind of surprises? Here are two:

• Credit Default Swap settlements. There is no central repository of information about who owes how much to whom for their CDS obligations. Nor is there solid data on how much these CDS counterparties have in their capital accounts in the event of a default that triggers their obligation to pay up. For instance, I was surprised to learn that Goldman Sachs (NYSE: GS) had a $20 billion obligation in the event of an American International Group (NYSE: AIG) failure. Who else is out there with such obligations? Do each of these counterparties have the ability to get the government to bail them out by taking over the company to prevent them from having to pay? Probably not.
