Techs, which had been propelled by signs of an uptick in demand, battled to make headway in the face of conflicting signals. Computer maker and retailer Gateway issued a grim sales forecast and saw its shares plummet $2.56 or 25% to $7.696. UBS Warburg analyst Don Young downgraded the shares because due to the 'major revenue miss.' 'With an expense structure around 20% of revenues, we are not sure Gateway can compete,' wrote Young in reference to the downgrade. Gateway is locked in a struggle for market share with Dell and Compaq. Compaq, which made a more positive announcement earlier, dipped 39 cents or 3.3% to $11.29. Dell was slightly higher at $29.64. Microsoft rose 82 cents or 1.2% to $69.38 on a confident presentation by chairman Bill Gates at a consumer product show. Gates highlighted the company's sales of 1.5m. Xbox game consoles over the holiday shopping season. Intel was ahead 31 cents or 0.9% to $35.58. Oracle, Microsoft's biggest competitor, gained 26 cents or 1.7% to $15.75. Chipmaker Altera surged $1.02 or 4.3% to $24.92 said its sales were better than expected.
