5 Rocket Stocks for Another Week of New Highs

BALTIMORE ( Stockpickr) -- Last week came with some strong performance for stocks -- the S&P 500 managed to rally 1.56% between Monday's open and Friday's close, shoving the big index to a new all-time high.

But as well as the S&P performed last week, one small set of stocks managed to do better -- a lot better. I'm talking about our weekly list of Rocket Stocks.

Last week, our pared down list of plays returned 3.63%, besting the S&P's run by more than 200 basis points. That brings Rocket Stocks' total outperformance over the S&P to a hefty 91.3% over the last 223 weeks, a pretty strong record over an already stellar period to own stocks.

To make the most of that performance now, we're taking a closer look at five new Rocket Stock names worth buying this week...

For the uninitiated, "Rocket Stocks" are our list of companies with short-term gain catalysts and longer-term growth potential. To find them, I run a weekly quantitative screen that seeks out stocks with a combination of analyst upgrades and positive earnings surprises to identify rising analyst expectations, a bullish signal for stocks in any market. After all, where analysts' expectations are increasing, institutional cash often follows.

Without further ado, here's a look at this week's Rocket Stocks.

T-Mobile US

2013 is panning out to be a great year for shares of T-Mobile US ( TMUS) -- since the $21 billion cellular carrier officially went public earlier this year, its share price has climbed more than 57%. Even though T-Mobile is only the number-four carrier here in the U.S., its comparatively small business gives it the ability to grow at a breakneck pace. And with more than 1.1 million new customers added to the carrier in 2013, TMUS is living up to the hype.

T-Mobile US is the result of a combination of legacy T-Mobile and discount carrier MetroPCS. T-Mobile got a spectacular deal on MetroPCS' customer list - the micro-carrier traded for a tenth of the premium per user on the big names like AT&T ( T) and Verizon ( VZ). By joining forces, T-Mobile now serves 43 million customers across the two brands; as the firm unifies its business under the T-Mobile banner, shareholders should see some big efficiency improvements.
