"Thorp had decided to take the reins himself once again. He'd developed a strategy that looked promising. (What was it? Thorp wasn't talking.) In early 2008, he started running about $36 million with the strategy. By the end of 2008, the strategy - which he called System X to outsiders - had gained 18 percent, with no leverage."
Did you ever use a trend following strategy?

“I did. We began the research project in 2006, and launched the trading program in late 2007. It was promising, and we were thinking of bringing it up in large scale with institutional money. But in early 2010 my wife was diagnosed with brain cancer, and my heart wasn’t in it. Life is too short. I didn’t want to launch another major activity, so we gradually wound down the program."

What kind of Sharpe ratio was your program running?

“It was a little better than 1.0 annualized.”

“…it would have been a good product, and it seemed to be better 
than most of the other trend following programs out there that were managing a lot of money.”
