BALTIMORE (

TheStreet

) -- Another consecutive week of gains is behind us in the market, and yet another is underway.

Last week, the

S&P 500

gained a modest 0.84%, bringing the index's year-to-date returns to an impressive 10.78%. And today, for the first time since November, the S&P has entered quadruple-digit territory, breaking 1,000 in early-morning trading.

With positive numbers for the market, it's time to take a look at

Stockpickr's weekly Rocket Stocks portfolio

of beaten-down stocks with short-term catalysts for growth and long-term investment potential.

But first, let's see how

last week's ideas fared

.

Retail grocery stores did well last week, pushing up 1.02% on positive industry earnings.

Supervalu

(SVU)

, our grocery rocket stock, did quite a bit better, with a 6.38% gain in the last five trading sessions. Those gains came after the grocery giant beat analyst expectations in a weak business environment.

Another analyst darling last week was

General Dynamics

(GD) - Get Report

. The defense contractor rose 5.52% after it raised earnings guidance for the 2009 fiscal year.

Strayer Education

(STRA) - Get Report

jumped just 0.31% on the week, despite reporting strong guidance and results on Thursday.

Among last week's losers were

ArcelorMittal

(MT) - Get Report

, which fell 3.66% on the week after it announced much lower estimated steel volume through 2011, and

Abbott Labs

(ABT) - Get Report

, which fell on the threat of bearish technicals.

Now, on to

this week's rocket stocks

, which includes such stocks as

Visa

(V) - Get Report

and

Molson Coors

(TAP) - Get Report

.
