A leading investment banking, securities and investment management firm Goldman Sachs today upgraded ATI Technologies to Outperform from In-line based on the fact that ATI Technologies increased its market share in mobile standalone graphics according to a research.

The New York-based analyst firm quoted by Briefing.com believes that ATI Technologies expanded its presence in the market of discrete graphics processors for mobile computers from 51% to 59% and will remain well positioned over the next 2-3 quarters at least.

Research firms today agreed that updated financial guidance for NVIDIA (see this news-story) and challenges the Santa Clara, California-based graphics corporation faces with its new products are positive for ATI, whose revenue has been growing for a number of consecutive quarters and who is managing to win the market share from its rivals, presumably from NVIDIA, S3 and Trident.

The stock reacted on the stories immediately with the price of ATI’s stock closing at $12.00 with daily range between $12.00 to $12.75 and NVIDIA’s stock range between $18.36 to $20.16.

We hope to see more market share figures later this week.
