Tech stocks posted modest gains on Thursday as the broader market turned positive following better-than-expected jobs data.

Storage company Network Appliance ( NTAP) rose 1.8% after the company said it will buy privately held software company Onaro to strengthen its portfolio of data management products. Terms of the deal were not disclosed. Onaro increases data management efficiency for companies and helps them manage their storage for lower costs. Network Appliance was up 43 cents to $25.05.

IT products distributor Ingram Micro ( IM) saw shares jump 6.6% following an upgrade from Goldman Sachs to a buy from hold. Goldman Sachs added the company to its Americas Buy List on the belief that the recent weakness in the shares, which were down about 9% in December, offers investors a good entry point into the stock. Ingram Micro was up $1.17 to $18.97.

E-commerce company Digital River ( DRIV) gained 3% after the stock was upgraded by a Credit Suisse analyst.

With growth in revenue and EPS through the first half of 2008 expected to "reaccelerate," the company's valuation multiples near its historical ranges and "overly negative" investor sentiment, Digital River offers an attractive risk-reward ratio, the analyst said in a research note. Digital River added 99 cents to $33.69.

Chip makers Intel ( INTC) and AMD ( AMD) were down again, a day after Banc of America analysts said in a research note that they are adopting a more cautious stance on the sector because of a weak macro-economic outlook and higher-than-optimal inventory levels. Intel was off 68 cents, or 2.7%, to $24.67. AMD sunk 37 cents, or 5.2%, to $6.77 to a new 52-week low.

Business software maker Netsuite's ( N) volatile stock fell 7.5%. Shares of the company that made its debut on Wall Street two weeks ago were off $2.79 to $34.64.

PC-maker Dell ( DELL) fell 2.8% despite an announcement by the company that it will introduce a new slimmer and lighter 15.4-inch notebook starting at $499. Dell's rival Lenovo, meanwhile, said it plans to expand from its current base of business users into the worldwide consumer market. Lenovo said it will launch three new notebook and desktop models. Shares of Dell fell 68 cents to $23.71.

Online retailer Overstock.com ( OSTK) lost 12.3% after the company announced Jason Lindsey, a director, president, and chief operating officer has stepped down. Lindsey was also one of the co-founders of the company. Shares of Overstock.com were off $1.86 to $13.24.
