I can't figure out why anyone invests in active management, so asking me about hedge funds is just an extreme version of the same question. Since I think everything is appropriately priced, my advice would be to avoid high fees. So you can forget about hedge funds.
Eugene FamaThe distribution of the market is fat-tailed relative to the normal distribution... For passive investors, none of this matters, beyond being aware that outlier returns are more common than would be expected if return distributions were normal.
Eugene FamaAfter taking risk into account, do more managers than youโd see by chance outperform with persistence? Virtually every economist who studied this question answers with a resounding 'no.'
Eugene FamaPeople would be a lot more skeptical if they understood that there is an incredible amount of chance in the results that you observe for active managers. So the distribution of outcomes is enormously wide - but that's exactly what you'd expect by chance with lots of active managers who hold imperfectly diversified portfolios. The really good portfolios contain a lot of really lucky picks, and the really bad portfolios contain a lot of really unlucky picks as well as some really bad ones.
