Thorp's "Beat the Market" book was written prior to the existence of the option exchanges, so his initial strategy was based on warrants. His first hedge fund was Princeton-Newport (1969-1988), which averaged a 15 percent rate of return. He founded his second fund , Ridgeline Partners (1994-2002), which used a form of relative value trading. He is purported to have averaged between a 15%-25% return every year from 1966-2003. Thorp was writing a regular article in Wilmott magazine, not sure if he still is. Some of the archives are available on www.wilmott.com.
