The Chicago Board Options Volatility Index has dropped frm a high of 80 last fall around the time of the Lehman brothers collapse, to 30 last week. So has the volatility gone? No one can be sure. Sam Stovall, investment strategist for Standard and Poors does not thinks so. He says history has shown that the rallies in the depths of bear markets are different, because they are almost always followed by a retesting of market lows. The market tends to get adecline after it looks at the fundamentals and any deep seated problems that remain. Stovall's research shows that the market retested going back to 1957, and the average event lowered stock prices 7%, but in the really big downturns like the current one, the S&P went down about 14%, on average. Assuming that the market peaked on May 8 with the S&P 500 at 929, and acorrection of 14% ocurred, the S&P would be at 799. A drop of this magnitude would mean that panic would return, says Stovall.
