According to Alan Greenspan, which part of the market could spread to other sect

The reality is that the level of distress here definitely knocked down a couple of notches today. Stocks ended slightly higher, investors paid little attention to a worse-thah-expected inflation report, and comments from former Fed Chairman Alan Greenspan, who said problems in the sub prime mortgage market could spread to other sectors of the economy. So details now, the Dow Industrials as you can see at the Big Board adding 26 points and firmly back above that 12,000 level, the NASDAQ composite are up more than a quarter of a percent, the S&P 500 adding more than a third of a percent.
