marcus,you will have to make ur own system,what others intend to say is to improve that system & moreover it is 100% possible to beat Mutual Funds,they have lots of limitation than a retail investor/trader like you & me.
Hence to beat their performance cant be an intended goal,which an avgerage system with good Money mgmt. & Risk mgmnt. in place can do comfortably.
Plz think deeply & improve upon,which all of us are doing day in day out.
Best of luck.
