I'll be contrarian. The general wisdom is hold the fund with the lowest fee structure. However, if the fee structure is 0.07%, that's $70/year / 100k invested. Even if it's 0.44%, you're talking about $440. The fees on most funds are small enough now to not matter much. It's worth shopping for lower-fee funds, but the more you go below 0.5%, the less it matters. If I save $500 per year for 50 years, that's $25k+inter…
I'm not storing my retirement funds in the latter.
