Well, if he'd actually beaten the S&P by 6%/year for 40 years, he'd be a multi billionaire.Is Gary's performance hypothetical?

I guess that you would be able to adapt it to what you mention.Hi GAT,
can we modify pysystemtrade to test stocks by treating a stock as a futures contract with infinite expiration and no carry? We can use div/split adjusted data for that. However I'm not sure if I have to completely change the sharpe ratio calculations because cost of capital for holding a long /short stock is somewhat different from futures.
My honest opinion after decades in markets is that for long term investment buy and hold of a broad range of stock indices spread over geographies and currencies is the best answer you will get. Buy and hold with periodic rebalancing. Plus add bonds if you are willing to sacrifice some return to ensure lower DD and VolYes, it's hypothetical, but how does one choose a strategy without a robust backtest? Buy and hold equities backtests at 10% per year. Is that not good enough to be considered a viable strategy?

You're right @truetype, my calculations were off. The last 9 years have basically been a wash between Gary's strategy and buy/hold. But if you pick the 9 years after 1975, it's also basically a wash. So, naturally there will be periods of underperformance, but taken as a whole, over 40 years, the outperformance seems much more statistically significant than any cherry-picked 9 year period.Taking the spreadsheet you sent at face value, aggregate performance 2009- 17 is -1.8% and it's unclear whether that even includes transaction costs.
