Johnson & Johnson is about as close to a “buy and hold” name as Cramer will ever get. He was a fan back in the days when he worked at Goldman Sachs, stayed loyal to the company while running his hedge fund and has been recommending the stock on Mad Money for the past four years. Still, if the company’s fundamentals changed at all, he’d sell J&J in a heartbeat.

That’s why Cramer doesn’t endorse “buy and hold” investing. When a stock isn’t working, he said, dump it. You can always buy it back later at a better price. This type of active money management is what smart investors do. So ignore the “professionals” who want you all in all the time. That’s just irresponsible.
