I have transitioned the vast majority of my investments to Fidelity Spartan funds like FSTVX/FSGUX etc. The only investments remaining are in my taxable account which are invested 23% in FAMRX (Fidelity 85/15 mutual fund) and 77% in FFNOX (Fidelity Four in One). I'm currently sitting on about $3,300 long-term capital gains between the two so if I sold now it looks like I would be on the hook for about $500. I figure the expense ratio savings over time would greatly outweigh the $500 hit I would incur now, any reason not to sell?
