We show theoretically and empirically that no-arbitrage pricing magnifies the importance of noise when replication requires offsetting positions with similar fundamentals. This occurs because fundamentals are hedged, while any errors in the underlying asset prices are levered and amplified....

We demonstrate that a broad set of asset pricing factors (anomalies) are significantly exposed to "noise trader risk," and the noise trader risk is priced in factor premia. We first confirm that mutual funds' flow-induced trades of factors are uninformed as they generate a large price impact on...

We study the equilibrium implications of a multi-asset economy in which asset managers are subject to different benchmarks, and demonstrate how heterogeneous benchmarking generates a mechanism through which fundamental shocks propagate across assets. Fluctuations in asset managers' capital...
