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 of even bigger and better gains to come.

Today, we've compiled 10 stocks that made some of the biggest upward moves over the past month. We'll then pair 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 according to changes in consumer sentiment, there will be months like this one, in which we see gains that are exceptionally ahead of the pace of the movers and shakers of prior months. So before we get shaken out again, let's see why the CAPS community thinks some of these companies might continue to outperform the market.

A mighty temblor
If eating just three glazed donuts instead of the whole box and walking to the sidewalk to pick up your newspaper is what you consider "diet and exercise," the results from VIVUS' anti-obesity drug Qnexa may get your heart beating faster.

Two late-stage trials showed impressive weight loss potential in participants, specifically placebo-adjusted body weight loss -- a key measurement for the FDA. The pharmaceutical company said it would submit safety data to the FDA by year's end. When you add in the positive developments that Arena Pharmaceuticals (NASDAQ:ARNA) announced two weeks later for its competing locaserin therapy, you just might be swearing off bean sprouts and the treadmill for good. Not that you should, but the promise of a "diet in a pill" regimen holds appeal to the exercise-averse.

When it comes to investing, though, timing is everything. Highly rated CAPS All-Star sanjaymathew waited for the inevitable pullback after the initial run-up before committing to VIVUS: "Stock is down 7% today. Good time to add to Caps. should more than double from here. Very impressive results for Qnexa."

Not that you should try to time the market, but if you believe in the future success of Qnexa, buying shares when everyone else is pulling back might not be a bad idea.

Feeling the aftershocks
Commercial real estate is the ticking time bomb that has the potential to sink whatever nascent economic recovery is under way. So concerned is the federal government that it's readying the next bailout for the sector: The IRS issued new rules two weeks ago making it easier to refinance some commercial mortgages to stem the rising tide of defaults. Loans that are part of investment pools known as Real Estate Mortgage Investment Conduits, or REMICs, could be refinanced without triggering an income tax penalty for investors, which they currently do.

Delinquencies in commercial property loan pools have almost tripled so far this year, and even worse, more than $2 trillion worth of commercial mortgages are set to come due over the next few years.

It might be surprising, then, that REIT Maguire Properties, which just last month stopped making payments on more than $1 billion in loans, should see a share price increase since then. After all, commercial mortgage loans held by REITs would not be covered by the new regulations, although the IRS is considering extending the break to them as well. It leaves CAPS member DarthMaul09 wondering why people hold out hope for a company that is locked into such dire conditions:

Optimistic price rise of a property company where the shaky ground is not limited to just earth quakes. The economies in those areas are not likely to recover quickly, which begs the question, why would property prices or rental income rise in these areas?
