New York)

Fidelity made history this week by introducing the first zero fee funds, which will track very broad self-indexed markets. Fidelity’s move is somewhat of a ploy, and definitely a demonstration of scale, as the company has many ways to profit from a customer once it has them in the door. But don’t be fooled, as fees aren’t everything. In fact, there are significant differences in performance even between index trackers of the same benchmark, like the S&P 500, and the differences between them can add up to a whole lot more than the difference in fees. For instance, Schwab and Vanguard already have broad index trackers at 3 and 6 basis points of fees, so hardly a big difference to zero, especially if their performance is better.

FINSUM: “Zero” definitely changes things, but once you are in the sub-15 bp fee category, performance is going to make a bigger difference than fees.
