Abstract: We conduct a spectral analysis of the relation between capital flows and mispricing. Hedge funds (smart money) and mutual funds (dumb money) both behave as low-pass filters, deploying high-frequency flows towards low-frequency mispricing in opposite directions. But hedge funds attenuate high-frequency flows more than mutual funds do, thus improving market efficiency 2 to 7 times more slowly than mutual funds worsen it. Time-series and cross-sectional tests indicate that limited access to capital and implementation costs are the reason hedge funds behave as low-pass filters. Our results highlight the markedly different influences of smart and dumb capital on market efficiency in the frequency domain.
