Do my 401k/Roth accounts benefit from compounding?
During the course of the year, the S&P individual stocks will have some dividends. Not every last stock but a good number of them. Enough that the average dividend for the S&P has been about 2% recently.  So if the S&P index goes up, say 10%, an S&P fund should go up closer to 12%. For a fund holder, you'd normally see a declared dividend and cap gain distribution toward the end of each year. When you hold shares in a 401(k), dividends are reinvested into the fund, usually with no involvement from the members.
