Using an exception to compare or measure the rule is not a good plan.
If you're using 30% gains per year to measure this question and see into your future and form a plan, you are blinded by optimism.
If you use a more normal annual return of 8% - 12%, then you can see why people want to enhance paltry gains. Whether you should or not is an entirely different matter.
If you can find a fund that consistently beats the market, why wouldn't you pay 1% for that managed fund?
Who would you rather have sex with, a live person
or a robot? An activly managed fund manager can
move in and out quickly. In many cases its worth the
slightly higher cost. One of my best funds is Fidelity
Low Priced Stock Fund (FLPSX) which over the years
has done very well with a cost of less then 1% If you
do some research, you will find many good funds that
do better then index funds.
Why should I pay 1%-3% per year for an actively managed mutual fund when SPY, the S&P500 index ETF, returned about +32% in 2013. US Small cap index ETFs returned about +38%. Their fees are around 0.1% per year.
