NEW YORK ( TheStreet) -- Check your emotions at the door and don't fall in love with your stocks, Jim Cramer proclaimed to his "Mad Money" viewers Wednesday. He was responding to ferocious criticism regarding Tuesday's recommendation to take profits in Arena Pharmaceuticals ( ARNA). Cramer said emotions are ruling the day in today's markets and that goes against everything he's taught on "Mad Money." Stocks are only pieces of paper linked to companies, he reminded viewers, and are not worthy of any affection. Good investors are always skeptical and must always challenge their reasons for owning a stock. Just as Cramer always says that "no one ever made a dime panicking," he also preaches the opposite, that "no one ever got hurt taking a profit." Stocks are still part of the overall market, which means even if they're terrific they can still go down. The holy grail of investing, said Cramer, is taking profits and playing with the house's money, a proposition where you simply can't lose. "Diversification and dividends are your only friends," Cramer concluded, as gains in a market like this one are getting harder and harder to come by.
