We define benchmark drift based on changes in a fund's beta relative to its self-promoted benchmark, calculated from the portfolio holdings of both the fund and benchmark. Benchmark drift has a strong adverse impact on mutual fund flows, even when funds beat the benchmark. Moreover, controlling...

We contend that the confluence of portfolio similarity and correlated liquidity shocks within mutual fund styles can exacerbate fund exposure to liquidity risk.
