SAN FRANCISCO -- CNet (CNET) - Get Report is up sharply even as the tech sector remains mostly flat.

The stock rose 15 3/8, or 13%, to 130 after hitting a high of 139. The window for employees to sell stock closed Friday, eliminating a factor that could weigh on the stock, a spokeswoman said. CNet's


division will present at the

Hambrecht & Quist


conference in Utah today, while CNet will present on Tuesday.

Elsewhere, computer hardware makers continue to retreat on a

cautionary note from Wall Street.

Meanwhile, online trading at

Charles Schwab


went out Monday morning for the second time in less than a week. Customers were unable to trade through the Web from about 10 a.m. EST to about 10:20, according to a Schwab spokeswoman.

The No. 1 online broker by online transactions also suffered an hourlong breach in Web trading last Wednesday. While Schwab is still investigating the source of the problem, a spokeswoman says it could be related to the system enhancements Schwab is making. The Wednesday outage was related to the installation of a new mainframe computer.

Schwab was trading 1 3/8 lower at 73 3/16.
