Sixty long-term mutual fund managers experienced organic growth of at least 10 percent in the first 11 months of 2011, according to Strategic Insight . That's up from 37 fund firms for all of 2010.

Avi Nachmany, director of research at the New York-based research firm, attributed the increase in part to the "broadening appeal of non-traditional strategies in 2011."

DoubleLine topped the list with $10.7 billion in net new flows through November. Rounding out the top five are Stone Harbor, Yacktman, AQR Management and Cambiar.
