      A fun questions for quants: if I tell you that I have a 5 sharpe strategy, how much data do you need to believe it? How would you go about expressing that it is reliable?

      First I would ask how many parameter combinations you tried to come up with the strategy.

      Also the length of the backtest (in years).

          Would this also depend on the frequency of strategy as well?

          This is a really interesting question, and of massive practical importance if you are managing systematic strategies. To generalize a bit -- someone tells you they have a strategy with a Sharpe of S. What questions should you be asking about the strategy to verify that it's real? https://twitter.com/o_wutang/status/1359686542466445312 …
