Editor's note: The following are questions received from viewers of "Mad Money," seen every day at 6 p.m. EST on CNBC. How do you look for a bottom in a stock? -- Ed from Tennessee James J. Cramer: That's a good question and one that I devoted an entire chapter of my latest book to answering. In short, you must be able to gauge the market's sentiment to find a stock that is about to reverse its recent losses. And as with most strategies in this market, this is contrarian thinking. The best time to try and buy a stock near its bottom is when you have analysts downgrading and investors running to sell a good, quality company. Want more Cramer?
