We propose that the arrival of new information is a source of systematic risk for the holder of a financial security. Using several measures of information flows, we demonstrate that a stock’s sensitivity to market-wide information flow is associated with a robust cross-sectional return premium that is distinct from other return premia. We find that the amount of information impounded in prices through trading has increased in recent years consistent with declining trading costs and the rise of algorithmic trading. We show that the information flows risk premium is increasing through time.

We investigate the new reality of exchange-traded funds (ETFs). We show that most ETFs are active investments in form (designed to generate alpha) or function (serve as building blocks of active portfolios). We define a new activeness index to capture these dimensions, finding that the cross-section of ETFs is now increasingly characterized by highly active investment vehicles. Active-in-form ETFs have positive flow-performance sensitivity, charge the highest fees among ETFs, and have high within-portfolio turnover. Active-in-function ETFs have more concentrated holdings, less within-portfolio turnover, but higher turnover in the secondary market. We show how more active ETFs are gaining market share over less active ETFs, leading to competitive fee pressure both within the ETF space and across the investment management industry. We suggest that the growing activeness of ETFs may assuage concerns about ETFs harming price discovery.
