TECH STOCKS: Terrorism Fears Send Markets LowerTECH STOCKS: Terrorism Fears Send Markets Lower

The fear of terrorism isn't good for business. It sent stock markets tumbling around the world Monday and extended Wall Street's sell-off into a second week.

U.S. investors reacted to market declines in Japan and Europe following reports that the al Qaeda terrorist network had claimed responsibility for weekend attacks in Turkey and named Japan and other U.S. allies as potential targets. But analysts said some of Wall Street's slide was because of normal profit taking. "This market is vulnerable to good news, bad news, or no news, so certainly the news of terrorist activity over the weekend and new threats from al- Qaeda will provoke a reaction," Alfred E. Goldman, chief market strategist at A.G. Edwards & Sons Inc., told The Associated Press. "But I do not see a serious downside from here; there's too much good going on."

The Dow Jones industrials fell 57.85 points, or 0.6%, at 9,710.83, following a weekly decline of 0.4%. The Standard & Poor's 500 index lost 6.72 points, or 0.6%, to close at 1,043.63. Tech issues were down even more: The information 100 fell 6.52 points, or 2.1%, to 301.71, while the Nasdaq composite index fell 20.65 points, or 1.1%, to 1,909.61. The Nasdaq-100 tracking stock fell 36 cents to $34.68, as more than 108 million shares changed hands.

Sun Microsystems said it's planning a partnership with chipmaker Advanced Micro Devices, an alliance that could help the two companies better compete against larger producers such as Intel. Sun fell 2 cents to close at $4.08, while AMD fell 50 cents to $17.36. Intel fell 57 cents to $32.23.
