Stock prices are swinging sharply on Wall Street, with investors still selling heavily but also scooping up stocks that have been decimated by more than a week of huge losses. The Dow Jones industrials are showing the market's volatility. They fell nearly 700 points soon after trading began, regained all of that deficit to show an advance, and then turned lower again.

Any gains in stocks Friday are likely the result of computer-driven "buy" orders. They kick in when stocks have fallen to a certain level.

There is no change in the market's deep despair over frozen credit markets that are posing a threat to the economy. Stocks around the world have also fallen sharply.

The Dow Jones industrial are down 32 points at the 8,546 level. The other major indexes are narrowly mixed.
