I use Cramer's method of selling in stages (maybe with covered calls on dividend stocks)or if I think a stock has a lot of upside, I trade around a core (sell some on big up days and buy some on big down days, over and over.) I don't know enough to try to get in at the bottom or sell near the top.
Cramer is telling people to be careful in this market. He says CRM bounces higher than other stocks after market downturns. To me, that means buy after a dip. He's not saying load the boat on any stock at this time. There is too much political risk for almost all stocks. I have heard Cramer say numerous times that Salesforce.com is a great company with a fantastic future and a stock to buy a toehold in with the idea of buying more "as it goes down." That is how Cramer buys--in stages. So he would buy a little CRM when it pulls back a little. Then hopefully get more when it dips the next time, etc. Why not take the time to watch Mad Money for a week to get a true idea of his methods? They are fantastic. Or read one of his books. Easy to read and full of information and market insight. If you just look at individual picks, especially quick comments he makes during the Lightening Round--remember that Cramer makes mistakes; he also buys and sells as opposed to traditional buying and holding.
