Jim Cramer says TJ Maxx had a hard couple of months as the stock went from the 60s all the way down to the low 50s. Cramer says that would've been a good time to scoop up the stock but investors were worried the company would further disappoint. Now, the stock is starting to come back. Cramer says expectations were so low that with just 'OK'. numbers, the stock is a 'buy' again. Quarterly profit came in a couple of cents better than expected and sales topped estimates. The company also raised its outlook. Comparable store sales were up 3 percent. Cramer says never bet against TJX CEO Carol Meyrowitz.
