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 listed three stocks that made some of the biggest upward moves over the past month, which we'll pair 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.

Stock

1 Month  % Change

CAPS Rating (out of 5)

Gramercy Capital (NYSE: GKK) 90.7% *****
Uranium Resources (Nasdaq: URRE) 77% **
TeleCommunications Systems (NYSE: TSYS) 68.6% ****

One-month % change from Sept. 10 to Oct. 11.

As the markets whipsaw to changes in changes to second half economic performance, the S&P 500 has been volatile. 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
The decision to purchase up to four million shares of its preferred stock for $15 a stub is apparently all the catalyst Gramercy Capital needed to begin its bullish run. The stock, which had been rather flat throughout the summer, soared on the announcement and hasn't looked back.

Commercial real estate has been trapped in a vicious cycle of burdensome debt, plummeting property values, and sagging rents. There's 1.4 trillion worth of debt coming due in 2014, rents are 12% below their 2008 highs, and vacancy rates continue to climb, albeit at slower rates.

REITs like Resource Capital (NYSE: RSO) have been feeling the crunch, but real estate finance company Gramercy has been looking for a way to make the situation profitable, much like Annaly Capital (NYSE: NLY) has carved a niche out of profiting off the spread between the cost of what it borrows and the interest it earns on its agency-backed investments. Gramercy has its own niche, acquiring and managing commercial properties primarily leased to large national banks, as well as mid-sized and community banks. Its goal is to selectively sell properties to generate a stable stream of earnings while shielding them from taxes as much as possible.

You can capitalize on the show of confidence by letting us know on the Gramercy Capital CAPS page whether you think commercial real estate is poised to pop or set to surrender the gains its made.

A sunny disposition
Although the CAPS Uranium sector has been glowing with better than 15% returns over the past month, fueled by Cameco (NYSE: CCJ) and to a lesser extent USEC (NYSE: USU), what's really causing the sector melt up has been the performance of Uranium Resources and Uranium Energy. Both have seen stellar gains in the past month.

In his mid-year letter to shareholders, Uranium Energy's CEO pointed to strong uranium pricing and the Obama administration's support for the industry as signs that things are only going to get better from here. Perhaps more importantly, global demand for uranium also outstrips supply.

Uranium Resources also has a reason to feel good. It cleared a hurdle last month in the legal wrangling over its New Mexico project, a project delayed for more than a decade, which by extension proves the difficulty nuclear projects have in overcoming objections, and it also regained compliance with the Nasdaq exchange to keep it shares listed.

CAPS member yipeokia joins with other CAPS bulls in seeing the potential in Uranium Resources. 89% of those rating the miner believe it will go on to outperform the broad market averages.

A speedy opportunity
Mobile communications technology company TeleCommunication Systems has also been rolling in the good news lately, enjoying the benefit of two new orders from the U.S. Army, which came on top of another military contract. The stock has been beaten down for most of the year and has been working overtime to make up for that.

Earlier this year I noted that TCS is a victim of circumstance. Its revenues are based largely on the beneficence of the government, and contract awards can be lumpy. There was every reason to believe it would be awarded additional contracts in the future -- and the most recent are proof of that. But as I also pointed out, as social networking messaging system Twitter grew, so would TCS since it is the real power behind the service.

CAPS member tobgj says that if you add up the pieces, it's easy to see why TeleCommunication Systems is a good buy:

High value recent contracts good track record attractive industry undervalued stock = buy
