NEW YORK ( TheStreet) Keep listening to those conference calls, Jim Cramer told the viewers of his "Mad Money" TV show Friday, as he outlined his game plan for next week's trading. Cramer said the sentiments from individual companies will be far more telling than any macro-economic data. Cramer said it's time to buy J Crew ( JCG) ahead of its earnings on Monday. He called the company "the finest retailer in the country," with strong management and easy comparisons. He said he'd also consider Men's Warehouse ( MW), another firm with strong same-store sales growth.
