1. Index funds outperform actively managed funds of the same riskActive funds 65b.p. below indexes.Charge fee of 130 b.p.Bring information worth 65b.p. but charge 130b.p.
2. Funds that charge higher fees tend to do worse that funds that charge lower fees
3. Funds that perform well have a slight tendency to continue to perform wellFunds that perform really badly tend to continue to perform really badly
32
4. Investors seem to be aware of this.Funds that perform well have higher subsequent cash flows.Funds that perform badly have high cash out flows.
5. The result of this is that new investment and disinvestment earns a risk adjusted return slightly above that which would be earned on a set of index funds with the same risk.
