I just released my long-awaited study of the 10-year track records of mutual funds. The study is called "Mutual Fund Costs: Risk Without Reward"

There have been numerous academic studies on mutual fund returns over the years. My study is not meant for an academic journal, but it is unique in that it looks at the effect of both Expense Ratio and Turnover on both pre-tax and after-tax returns for several different categories of funds.

My study shows very clearly how much better low cost funds perform over high cost funds: higher average returns, greater odds of "beating the market" if that's what your trying to do, and lower risk of being disappointed. Find out what the odds of success with mutual funds really are.

There's lots more good stuff in there: Find out why calling the S&P 500 the "market average" is misleading. Also, have you ever seen one of those charts that shows that $1 invested in the S&P500 in 1926 would be worth over $2,000 today? That's largely nonsense. A more realistic (and far lower) range of estimates is in the study . It's available for free download.
