Some stocks are one-hit wonders, making a big splash when they first appear, then quickly fizzling into obscurity or oblivion. But for other stocks, that initial big move is only a preview for even bigger and better gains to come.

Today, we've compiled a list of 10 stocks that have made some of the biggest upward moves over the past month. We then paired that list with the ratings issued by our Motley Fool CAPS community. The higher each stock's rating, the greater CAPS members' faith in that company's ability to keep on beating the market.

As the markets whipsaw to changes in consumer sentiment, there will be weeks like this one where we see gains that are exceptionally ahead of the pace of the movers and shakers of prior weeks. So before we get shaken out again, let's see what the CAPS community thinks of one of these companies and whether it might continue to outperform.

A mighty temblor
Chip maker Advanced Micro Devices has been vindicated by the antitrust settlement reached with archrival Intel (NASDAQ:INTC), which agreed to fork over $1.25 billion. Intel also said it will stop "urging" manufacturers to limit use of AMD chips and will allow it to make some x86-compatible chips. And verily did the lion lie down with the lamb.

The agreement provides AMD with much-needed cash, not to mention detente with its nemesis, which allows the chip makers to go forward focusing on their respective strengths. But it raises the question of whether it's a case of too little, too late. Despite what many consider to be the technical superiority of AMD chips, it has never owned much more than a quarter of the market share, and that was back in 2006.

Even with the settlement, though, CAPS member mfa066 isn't enamored: "Despite [receiving] the Intel cash, this company still has [fundamentals] that are simply terrible. Couple that with the CEOs expectation of 'Moderate Profits' during Q4 as noted in their most recent conference call, Q4 may be a good time to short/put."

But perhaps it doesn't have to have market dominance to still be a successful, profitable investment. Analysts anticipate AMD will be able to gain more of the industry now, though unseating Intel is hard to picture. Yet it's also true that Intel is diversifying away from the processor market, and will be trying to gain a bigger foothold in mobile chips, where it will have to take on others already entrenched there.

By ceding ground to AMD and taking its eye off the processor market, Intel may be giving AMD a larger piece of ground than many bargain for.

CAPS member jsquaredco sees just such an occurrence, particularly in European markets:

Remove the litigation risk, the lowering of credit costs from improved bond ratings and you have all the pieces necessary for a robust increase in share price. Yes, they can botch the releases as we've all seen in the past but barring that event, there is simply no way AMD doesn't pick up market share from [Intel], especially in the EU. A few percentage points of market share is a game-changer for AMD.

Shake, rattle, and roll
