Andy.. it is not enough to look at returns but the variance of those returns. It is not too hard to backtest a strategy with the benefit of hindsight and produce those returns.What is hard is real money implementation. Even if it is real trading, strategies could produce those return but have a high risk of ruin. I have friends here in CT (hedge fund havens) with > $250m AUM and they tell me a verifiable record > 10% with a LOW STANDARD DEVIATION will start to attract big investors. So if they have a 70% return. they would never sell it, they would run over to the Citadels of the world , get an allocation , run it and get their 2%/20% and not deal with the "public".
