The

Dow Jones Industrial Average was weighed down by a less-than-stellar profit report from an industry giant, while tech shares made strides in trading Tuesday.

The Dow finished down 46.50 points, or 0.5%, to 10,150.55. The

Nasdaq gained 18.63 points, or 0.9%, to 2055.73, and the

S&P 500 was off 4.18 points, or 0.4%, to 1160.71.

The news flow from corporate America was picking up as the holidays came to a close and Wall Street began to prepare for fourth-quarter earnings season. Investors had plenty to digest Tuesday, sorting through a wave of earnings forecasts and other news from technology and media sectors.

was trading lower a day after disclosing plans to

take a charge of up to $60 billion, one of the largest ever, to write down the value of the stock used in the merger that created the company in 2000. AOL also predicted only modest growth in 2002 and said it would use cash to buy out
