There's an urban legend about McDonald's and Burger King: McDonald's wanted to outsmart its rivals and spent tons of money researching the best places to put its restaurants. Burger King responded by just opening restaurants across the street. The Buffett Buffet works the same way: let Warren Buffet do the work for you, and get a better deal than he did. The Buffett Buffet tracks every stock in Warren Buffett's portfolio. If the current price is less than what he paid, you'll get a notification.
