Tech stocks were getting roughed up again Thursday as Federal Reserve chairman Ben Bernanke's comments on an economic stimulus package failed to impress Wall Street. The tech-heavy Nasdaq composite index was down 10.91, or 0.46%, to 2,383.68, in afternoon trading. The index is down 10% this year. In Wednesday's session, declines were running 2-to-1 ahead of advances, with 240 stocks sinking to new lows vs. only 18 hitting new highs. Investors were waiting for favorable news from bellwether stock IBM ( IBM), which reports its earnings after the close. The company had indicated earlier that four-quarter profits will come in higher than estimated. The stock is up 60 cents, or 0.59%, to $102.23, in recent trading. The tech giant is planning to announce next week an email software package for Apple's iPhone and iPod Touch devices. Advanced Micro Devices ( AMD) will also report its earnings after the close of trading. Analysts have been critical of the chipmaker's performance in the PC market. Analysts polled by Thomson Financial expect AMD to lose 36 cents a share. The stock was down 25 cents, or 3.8%, to $6.32 in recent trading. eBay ( EBAY) was up 1% after an analyst upgraded the stock to outperform and set a target price of $36. Bears Stearns analyst Robert Peck said investor fears had sent the stock too low. The stock was up 28 cents to $28.37 in recent trading. Tibco Software ( TIBX) was up 0.93% after getting an upgrade to buy from hold. John Reilly Walsh, an analyst with Citigroup, also raised his target price to $10 from $9. A number of suitors have been been mentioned as interested in buying the middleware vendor, including IBM and Hewlett-Packard ( HPQ). Interest in Tibco has grown after Oracle's $8.5 billion acquisition of BEA Systems ( BEA). In recent trading, Tibco was at $7.53, up 7 cents for the day. Riverbed Technology ( RVBD) was down 6.86% after a UBS analyst reduced his target price for the stock to $24 from $34. The stock was at $19.41, off $1.43, in recent trading. Saud Masud, the analyst, said the company may see a falloff in project activity in the upcoming months.
