It’s becoming clear that the price for overall U.S. equity market exposure is close to zero. Many market-cap weighted index funds and exchange-traded funds from Vanguard and others are charging expense ratios of five basis points (bps) or less. An interesting, and more difficult, question to answer: How much are you paying to gain exposure to small-cap and value stocks across the funds in the marketplace? This is more difficult to answer because a fund that calls itself “small cap” may own stocks that are materially smaller than another fund that also has “small cap” in its title. The same is true for funds with the word “value” in their names.
I explore one methodology here by running Fama-French three-factor regressions for a large number of Vanguard and DFA funds and using the output to tease out how much additional expense ratio investors are paying on average for small-cap and value exposure, respectively. (Anyone who is interested in the exact methodology can email me. The details are too laborious to include in the blog post.)
