Fool.com: A Value Investor's Secret [Commentary] December 5, 2003:

"Value investors come in all shapes and sizes. Some invest in real estate, others in bonds (generally distressed ones), still others in stocks. Some specialize in certain industries or countries, while others are generalists. But most value investors have two things in common: (1) They seek to buy at a significant discount to intrinsic value (the proverbial dollar bill for 50 cents); and (2) They generally sell once intrinsic value has been reached."
