Ruane Cunniff

Ruane, Cunniff & Goldfarb L.P.

Bill Ruane and Rick Cunniff started the firm in 1969 in the belief that they could outperform the stock market by investing in great businesses selling at reasonable prices and staying with them as long as they remained attractive. By doing exhaustive primary research, ignoring fads and sticking to their principles, the firm has built an enviable track record. William Ruane was a Graham-and-Doddsville superinvestor recognized by Warren Buffett. He was a student of Benjamin Graham, and attended his class at the same time as Warren Buffett.
