Explosively, professor Bradford Cornell’s recent brief analysis of the performance of Renaissance Technologies’ Medallion fund states that “to date, there is no adequate rational market explanation for this performance.”
I find this conclusion interesting — not because of its contribution to our understanding of the Medallion fund’s performance (such efforts have devolved into a parlor game), but because it accidentally reveals an implicit worldview that, upon reflection, is a root cause of the dismal record of active management.
This belief rests on the conceit that investing is essentially a human activity — and therefore human reason must be able to explain the results of such activity.
