At the end of business yesterday, graphics chipmaker announced its third-quarter results for the period ended October 30. Highlighted by profits more than double those of the same quarter last year, the stock surged in after-hours trading, surpassing the $35.95 52-week high it set in early October. Investment firm Global Crown Capital even upgraded its rating on the stock from "neutral" to "overweight."

　　Nvidia reported revenues of $583 million for the third quarter, up from $516 million from the same quarter a year ago. Furthermore, the company's net income came in just over $65.3 million, a 152 percent increase over the $25.9 million net income of a year ago.

　　Among the company's third-quarter highlights contributing to those figures were the launches of several new products, including the nForce 400 media and communications processor (MCP) and GeForce 6100 integrated GPU lines, the GeForce Go 7800 GTX notebook GPU, and Motorola and Sony Ericsson mobile phones using Nvidia GPUs. It was also a big quarter for Nvidia's Quadro brand, as the workstation product line achieved record revenues, and Apple announced a Power Mac sporting the Nvidia Quadro FX 4500.

　　Despite an initial spike in the stock's price in after-hours trading, that news evidently wasn't enough to satisfy investors. The stock closed Wednesday at $34.78 and opened Thursday at $36, only to slide back to yesterday's prices and below. The stock bottomed out around noon Eastern time at $32.84, and as of press time, it had recovered to $33.81, still almost 3 percent off yesterday's closing price.
