The tech sector advanced Monday morning, as shares of Brocade Communications soared on a news that the networking gear maker was up for sale.

Brocade (BRCD) was up more than 15% in the opening minutes of trading, after the Wall Street Journal reported, citing unnamed sources, that the company was considering selling the company.

The Nasdaq Composite Index (RIXF) rose 0.1% to 2,050, while the Morgan Stanley High Tech 35 Index (MSH) added 0.1% and the Philadelphia Semiconductor Index (SOX) was up 0.2%.

The tech sector got a boost from other players, including Research In Motion (RIMM) and SanDisk Corp. (SNDK), shares of which each gained more than 2%.

Meanwhile, shares of Advanced Micro Devices (AMD) sank more than 2% after FBR Capital Markets downgraded the chip maker to market perform from outperform, citing a "potential PC build pull-in."

Analyst Craig Berger said that, based on checks with contacts, "October builds will be the peak for PCs in 2009, whereas, usually November is the peak build month."

"While we do not want to get overly bearish on the PC space given improving global demand and unknown holiday sell-through trends, we feel these actions are prudent given peaking near-term momentum, more downstream inventory to digest (at least in China), and a potentially overheated PC supply chain," Berger wrote.
