And they're off. On the heels of Friday's stock market gains, the bulls are back on stampede this morning. In recent trading, the

Dow Jones Industrial Average was soaring more than 150 points, and the

Nasdaq Composite Index was forging ahead by some 30 points. So are we out of the woods yet?

Wall Street bears say no. They argue that last Thursday's 300-point downdraft on the Dow, which was followed by a late-day snapback and a subsequent rally on Friday, didn't mark a bottom, because there was no catalyst for the gains. According to the grizzlies, the corporate earnings outlook is still hazy, and the economic picture hasn't shown any clear signs of improvement.

But market bulls point out that the end-of-the-week comeback was led by significant institutional buying and that piles of cash remain on the sidelines. They think nuggets of good news may be right around the corner, namely comments from

Federal Reserve Chairman

Alan Greenspan, passage of Bush's tax-cut proposal, or visibility from bellwether companies, which could set a fire under the stock market.

Most sectors of the market were trading higher this morning: PC maker, drug, Internet, networking, cyclical and financial stocks were all up. But, noticeably, semiconductor stocks were moving down. The
