NEW YORK — Investors might be worried about the soundness of the market's rally but they're also worried about missing it.

Stocks reversed steep losses in the final hour of trading yesterday to end little changed. The Dow Jones Industrial average recovered from a 130-point slide to end up a little more than a point.

But volume on the stock market was light, and Stephen Carl, head of equity trading at The Williams Capital Group in New York, said that made the market susceptible to quick changes in direction.
