Index Funds are Driving Down Mutual Fund Fees for Everyone

Perhaps the only certain thing in investing is that index funds will continue to take the lion's share of new investment capital coming into the stock market. From 2009 to July 2016, passive index funds grew in every single year as investors added more money to low-cost funds. Meanwhile, active funds have experienced outflows as investors pull money from higher-fee funds and the pace of redemptions is accelerating.

Gaby Lapera: Why would you want to invest in an index fund?

Jordan Wathen:Theprimary benefit of anindex fund isbecause they don't employ managersto oversee the portfolio andhire very expensive analysts to go findstocks or bonds for it, stocks and bonds they think will be good investments. They can pass on those much lower costs to investors. There's a group out there calledtheInvestment Company Institute,and they basically collect information on theworld of investment funds. In 2015,the average stock mutual fund charged anexpense ratio of 0.8%. That's an actively managed fund, 0.84%. Now,index funds, on the other hand, cost0.11%in 2015 -- roughly 1/8 the cost for an index fund compared to an active fund.

Lapera:That's a huge amount. I realized thatwhen you're talking about anything that's preceded by zero point something, itdoesn't seem like it would make a huge difference. But if you spread that amount out over time, you're losing a lot of money in fees.

Wathen:Right.I just did it, but I hate when people put it in perspective of --the amount of assets under management,put it into consideration ofthe average return over time. Let's saythe S&P 500'saverage return might be 8%; we'll justgo with that figure. If you pay 0.8%, you'rebasically giving up 1/10 of your return. If you pay 0.1%, you'regiving up 1.25%of your return. It's an astronomical difference.

Lapera:It's huge. So,it's really important to look at expense ratios, which issomething that we'll actually get to in a little bit.
