. Plenty of academic researchers support the move, arguing that most active funds lag the indexes. Now an active fund company is fighting back.
American Funds, which oversees $1 trillion in assets, has published a report that makes the case for active management. Conceding that average funds trail, the company argues that some special managers win consistently. The report notes that it is a mistake to conclude "that because the average person cannot dunk a basketball, no one can dunk a basketball."
To support the case, American Funds cites the returns generated by its equity funds from 1934 through 2012. The study examines rolling returns. To calculate the rolling 10-year returns, you start by tallying results from 1934 to 1943, then you consider data from 1935 through 1944, and so on.

American Funds has maintained its performance over decades by carefully training portfolio managers and giving them incentives to stay. Few managers ever quit, and many of the current staff have been with the company for more than 20 years.

No other company can match the seven-decade record of American Funds. Still, there are some competitors that have consistently excelled over long periods. Among the best performers are Baron, Oakmark, Mutual Series, and T. Rowe Price. These companies all have many funds that have topped their category averages during the past 10 years.

Mutual Series has long followed a deep-value approach. The portfolio managers like unloved stocks with sound balance sheets.
