Tuesday wasn't one of the more memorable days on the stock exchange for U.S. chip titan Intel (INTC 1.98%). There was little fresh news affecting the company directly, still it managed to drift 2% higher in price across the trading session. Lingering positive sentiment related to the recently announced Nvidia buy-in, in addition to recent analyst moves, played a role in this. Mind you, the analyst didn't exactly join the bull stampede on Intel; still any upgrade is reason for renewed optimism. Speaking of Nvidia, Engel wrote that the company and fellow state-of-the-art chip manufacturer Broadcom are currently testing Intel's production platform, which bodes well for its future.
