During the past twelve months, Intel (INTC 0.47%) stock has served investors a 13.3% gain, underperforming the S&P 500's rise of 18.8% during the same period. Has Intel's underperformance provided investors a buying opportunity?

In the video below, Fool contributor Daniel Sparks and Motley Fool Technology Bureau Chief Evan Niu discuss Intel's prospects and the stock's valuation. Daniel explains that while ARM's (ARMH) microprocessor designs dominate the mobile device market today, it doesn't mean this will always be the case. In the past, Intel has been known to outspend and out invest its peers to maintain its competitive advantage -- and there's nothing stopping it from using the same strategy to make progress in mobile with its Atom line. Best of all, as Daniel points out, very little of this potential upside in mobile is priced into Intel's stock. The stock trades at just 13 times earnings.

Check out the following video to see why Daniel thinks Intel is a buy at today's prices.
