My parents contributed in the '80s and '90s to my non-retirement mutual funds, which are all SMMIX. The current value is about $98,000. The dividends are automatically reinvested as opposed to being paid directly back to me. However, compared to options like FSMEX or FSELX, they do not seem to perform as competitively. Each year, my 1099-DIV form for the SMMIX investments lists total capital gain distributions. Therefore, it seems I am paying taxes on them.
If I were to sell my existing funds to invest the money in FSMEX or FSELX, would I have to pay more in taxes, and, if so, would any potential performance increase be overshadowed by increased taxes?
