Abstract:Publicly traded institutional investors overweight their own companies’ stocks in their portfolios. Public institutions are momentum traders in general, but are contrarians when trading their own stocks. They purchase their own stocks during negative earnings announcements and large price declines, while selling other stocks around bad news. Public institutions are less likely to herd with other institutions when trading their own stocks. Public institutions’ stocks exhibit lower crash risk and contain less firm-specific information than other similar stocks. Our results are consistent with conflict of interests impacting the portfolio choice and trading decisions of institutional investors.
