Description
Summary:In response to the increasing proliferation of exchange‐traded funds (ETFs), and a warning from the Wall Street hero Michael Burry that passive investing has put the stock market into ‘bubble’ territory, we examine the relation between stock ownership by ETFs and mispricing from 2002 to 2018. We find that increased ETF ownership induces overpricing in underlying stocks. We then identify three mechanisms for this relationship: the overpricing of stocks attributable to increased ETF ownership is stronger for stocks that experience an increase in passive ETF ownership; during periods characterised by high investor sentiment; and for illiquid stocks. Our results are robust to a battery of tests including alternative measures for all key variables and are not confounded by the global financial crisis. Additional analyses show that mispricing caused by ETF ownership change is not driven by firm fundamentals and does not exacerbate stocks' information environment around earnings announcement.
