Winning strategies are not published generally speaking. You wont see many business people blogging in detail about how they went for 0 to 1. Which is shy most blogs about business are a load of BS. Reading your statement and this article confirms my long suspicion that relying on internet strategies is a bad startegy.

There are no winning strategies. Its all BS. There are people who are addicted to tracking weather fluctuations on Pluto and there are people who are not.

  There are definitely winning strategies. The issue is whether they can be reliably identified beforehand (thus rewarding skill), or whether people who implement them are just lucky (regardless of whether they believe they were skilled or not).

    If you can't tell untill aftarwards, it is merely a strategy that won, not one that will make you win.

  Ever hear of the Medallion Fund, which has averaged ~40% annual returns since the late 1980’s? https://www.bloomberg.com/news/articles/2019-03-07/jim-simons-reveals-clues-to-medallion-fund-s-long-unrivaled-run https://www.bloomberg.com/news/articles/2019-03-07/jim-simon...

    Well, if you get 30 persons to flip a coin six time, there is good chance one of them will get all tails or all head. Now ask him his strategy for such amazing coin flipping skills! (example taken from the book "statistics done wrong"[1]). I would be interested in seeing a total distribution of hedge funds return, not just outliers.

      But if you keep an eye on the lucky ones, they should also go back to being noise, if what you're saying is correct. Is that what happened?

        That would be the reversion to the mean[1]. This is a term I really dislike because it makes it sounds as if there is some sort of equalizing force making over-performers under-perform later. This is more the following: if you overestimates the expectation of a random process, you are going to be disappointed. In our case, this does not makes the "hot streak" any less probable when you start looking, for a specific edge fund. It is true it would be interesting to select a group of over-perfomer and study their future return to know if past performances are a good predictor of future performance. I feel you would probably get mixed results! Although as I said in the sibling comment, you are probably right, and no amount of statistics could explain performances seen in this particular edge fund.

      I understand what you are saying, but the equivalent to the Medallion fund would be something more akin to winning that same coin flip 30 times in a row. They have been running approximately 30 years, beating market returns by a significant margin, year after year. The 40% average is net of fees, so the overall return of their strategy has actually been higher than that. The odds that they have accomplished these returns through luck alone are astronomically low.
