MyMoneyMD, LLC Let me help you help yourself. This is what managing your own money could mean for you. Over your investing life, you have the potential to make your investments grow exponentially better than most professionals. This is why. Eight out of ten mutual fund managers can't consistently beat the market in any one-year. Over decades, the chances are much worse. Is there any reason to think that those in charge of private accounts do any better? By managing your own money, you can avoid the expense of a money manager and keep up with indexes that routinely beat the performance of mutual fund managers.
