An Analysis of the Recommendations of the "Superstar" Money Managers at Barron's Annual Roundtable.
The authors examine the performance of common stock recommendations made by prominent money managers at Barron's Annual Roundtable from 1968 to 1991. To avoid survivorship bias, they examine the performance of recommendations by all the participants. The buy recommendations earn significant abnormal returns of 1.91 percent from the recommendation day to the publication day, a period of about fourteen days. However, the abnormal returns are essentially zero for one to three year postpublication day holding periods. Thus, an individual investing according to the Roundtable recommendations published in in Barron's would not benefit from the advice.
