BALTIMORE (TheStreet) -- Last week marked the busiest week of Wall Street IPOs since 2007, the largest being A123 Systems(AONE Quote), a Massachusetts-based battery maker. The company raised $379 million in its offering, with shares appreciating 45% on their first trading day, a feat that IPO-tracker Renaissance Capital noted "is welcome news to many VCs and startups that have poured lots of money into the alternative energy space."

But elsewhere in the market, things weren't quite so upbeat. The S&P 500 index shed 2.24% last week after an update from the Fed and a number of economic metrics sank in. Still, our Rocket Stocks managed to fare better than the market once again, with an average slip of just 0.72% for last week's picks.

That brings our outperformance to 24% over the S&P 500 during the course of the last 10 weeks.

Our biggest gainer last week was CarMax(KMX Quote), which announced record second-quarter earnings. The stock gained 6.61% over the last five trading sessions. Our other car play, AutoZone(AZO Quote), didn't fare as well in its earnings call. The company managed to report in line with analyst expectations, but investors were hoping for one better, and the stock ended the week down 5.34%.

Spice-maker McCormick(MKC Quote) also managed to deliver solid earnings, but it saw its share price tumble 3.85%. The company's underwhelming revenue is likely to blame for that. Beating the market were Molex(MOLX Quote) and Chicago Bridge & Iron(CBI Quote), down only 0.34% and 0.67%, respectively.

This week, however, with Monday's markets opening higher on increased corporate action activity, stocks stand a chance at recouping some of last week's losses. Here's a look at this week's list.
