Q. The information in the TSP site under the fund comparison matrix for the S Fund says the objective of the fund is to match the performance of the Dow Jones industrial average’s Total Stock Market U.S. Completion Index. So of course I would think when the Dow goes up, the S Fund would go up, yes?
A. I suspect that you are comparing the commonly reported Dow Jones industrial average (or “Dow 30”) to the S Fund, which is based on a different Dow Jones index.
