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.
