Take-aways

  • Investors misinterpret the skill of active funds managers, and thus tend to accept the negative aggregate returns provided by the active management funds industry
  • In particular, investors fail to properly quantify the risks related to factor investing, and hence are baited by Fake Alpha strategies, for which they overpay

Quotes

"Investors would still provide flows to the funds in the long-run equilibrium even if the managers didn’t have any skill at all, since they confuse skill with risk premia on omitted factors"
"Investors tremendously overinvest into active managed mutual equity funds. (...) We estimate that the US equity active mutual fund industry is too large by about 23% of its actual size. (...) This means that within 2014 $21.9 billion would have been falsely paid by investors of active managed US mutual funds to their managers."
