Abstract: The average Swedish active mutual fund manager possesses no superior ability to generate abnormal returns (alpha) in managing her fund. However, the managers who invest (a lot of) personal wealth in the very same funds they professionally manage consistently outperform. The majority of managers do not commit any personal wealth to their own funds. These managers also invest more conservatively in their personal accounts, that is they hold more cash and more passively managed products. Overall, the results suggest that fund managers, contrary to fund investors, know about their ability---or more often lack thereof---and invest their personal wealth accordingly.

Abstract: Firm fundamentals, in particular firm size, help explain variation in factor loadings (betas) for the market, size and value factor. Surprisingly, however, they are dominated in terms of explanatory power by an unobserved time-invariant component. This leads to surprisingly stable factor loadings: stocks with high (low) factor loadings tend to remain as such for over a decade. Our models work best in explaining market betas (r-squares up to 64%) and worst in explaining value betas (r-squares up to 35%). These results are robust to different estimation techniques of factor betas and also hold up when we limit the sample to firms with statistically significant betas.

Abstract: Compensation of mutual fund managers is paramount to understanding agency frictions in asset delegation. We collect a unique registry-based dataset on the compensation of Swedish mutual fund managers. We find a concave relationship between pay and revenue, in contrast to how investors compensate the fund company (firm). We also find a surprisingly weak sensitivity of pay to performance, even after accounting for the indirect effects of performance on revenue. Firm-level fixed effects, revenues, and profits add substantial explanatory power for compensation.
