Positive return correlation signals slowly-diffusing information. Short sell-constrained institutions are mainly informed in their buy trades. Building on these facts, we identify informed investors ex ante by focusing on mutual funds. We propose a measure of the dynamic excess autocorrelation (DEA) of fund portfolios. High-DEA funds persistently outperform by 3.5% annually. Our framework shows that the DEA identifies informed managers who dynamically rebalance to buy portfolios with slowly-diffusing positive information, which are thus positively autocorrelated and subsequently outperform. We support such intuition with high- and low-frequency evidence. The DEA performance predictability stems from a novel portfolio-level, cross-stock linkage.
