Friday's show was "not about stocks, but about strategy," Jim Cramer told viewers of his "Mad Money" TV show Friday. He highlighted three stocks for which he's been waiting on a pullback so that they'd be cheap enough to buy, "stocks we've been waiting for a pullback on to do a 'mon back.*" With the "big bad employment number out of the way," everyone is looking to buy stocks because it's like an "all-clear siren" has been sounded, he said; the market has been miserable as traders waited to see how the February payroll report would play out. Now everyone wants stocks that were put on sale when the market was getting crushed and everything got cheap, but Cramer said that it's essential to buy only the best stocks in order to make a lot of money when the market goes higher. Plus, since next week is options expiration week and the March expiration has a history of going higher, he believes money is sure to be made. But to trade like a pro, you need to know what's been marked down because it's bad and what fell because it was crushed by bad sentiment. Cramer said that a winner is a company that reported a great quarter, whose stock went up and then was brought down because the market turned down.
