BALTIMORE ( Stockpickr) -- With the first trading day of the new month just around the corner, should you just "sell in May and go away"?Following that popular mantra would have worked out well for investors last year, sparing stock investors from some of the most painful drawdowns Mr. Market had seen since 2008. The success of selling in May and going away might tempt some investors to follow that clichéd advice again this year, but it's important to remember that this isn't 2011. This time last year, there were a slew of structural factors that were hampering stocks from moving higher. Both technically and fundamentally, things didn't look as strong as they do now. A combination of record corporate earnings and paltry stock price increases mean that, broadly, stocks are cheap right now. Even though Europe has some big black clouds overhead, investors seem to be taking volatility from the EU in stride better than before. >>5 Stocks Under $10 Poised for Upside So instead of selling in May and then going away, we'll focus instead on five new Rocket Stocks worth buying this month.

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. In the last 149 weeks, our weekly list of five plays has outperformed the S&P 500 by 80.34%. With that, here's a look at this week's Rocket Stocks.
