(MONEY Magazine) – Muhlenkamp is down 7.1% during the past 12 months--making it the worst-performing MONEY 65 fund for the period. But manager Ron Muhlenkamp is betting on a growth-stock comeback. Over the past year, he has loaded up his traditionally midcap fund with large-company stocks, including AIG and Pfizer. The fund is now 90% invested in big stocks. In other news, Vanguard VIPRs will now be called, simply, ETFs.
