Structure and taxes
FNCMX is a mutual fund and VOO is an ETF. A mutual fund prices once a day at net asset value and may carry a purchase minimum. An ETF trades through the day at whatever the market pays for it.
In a taxable account the difference that usually matters is distributions. An ETF can meet redemptions in kind, so it rarely has to sell holdings and rarely passes a capital gain to the people who held it; a mutual fund that sells holdings to meet redemptions can distribute a realised gain at year end to everyone still in the fund, whether or not they sold anything themselves. In a tax-deferred account that difference largely disappears. Both are descriptions of how the two wrappers work, not a recommendation.
Tax-loss harvesting works on either wrapper.
