At the risk of beating a dead horse, I am still confused about the benefits of an ETF over a mutual fund.
I understand the general premise (lower expense ratio, liquidity, paying taxes for other people, etc...), but it seems to me that it doesn't hold up when examining specific head to head examples...
For instance, let's take Vanguard S&P 500 fund (VFIAX) vs equivalent Vanguard S&P 500 ETF (VOO).
Both have 0.05% expense ratio, so that's a wash...
Since they both track S&P 500, there are no sudden stock sales that would have me paying taxes for stocks bought eons ago.
Why would I invest an ETF vs Mutual Fund (or vice versa) in this case?
