Abstract:
During the week of August 6, 2007, a number of high-profile and highly
successful quantitative long/short equity hedge funds experienced
unprecedented losses. Based on empirical results from TASS hedge-fund data
as well as the simulated performance of a specific long/short equity
strategy, we hypothesize that the losses were initiated by the rapid
unwinding of one or more sizable quantitative equity market-neutral
portfolio |
