This paper investigates share-price performance following corporate takeovers. We use multifactor benchmarks from the portfolio evaluation literature that overcome some of the known mean-variance inefficiencies of more traditional single-factor benchmarks. Studying 399 U.S. takeovers consummated in the 1975–1984 period, we conclude that previous findings of poor performance afer takeover are likely due to benchmark errors rather than mispricing at the time of the takeover.
