This one caught my attention because it clearly laid out the case against actively managed mutual funds....a $580k difference is eye opening!
Many mutual funds
Thousands of actively managed mutual funds (which employ stock pickers who try to beat the market rather than simply match its overall returns) charge fees of 1 percent or higher. Yet consider that less than 40 percent of actively managed funds that invest in large companies outperform the S&P 500 Index. Assuming an investment of $10,000 per year for 40 years, and an average annual return of 7 percent, a fund with a 1.5 percent annual fee compared to one with a 0.25 percent load will cost an extra $580,000. That's a yacht or a summer house.
