What are the gains from more liquidity in ETF for small investors?
In my opinion, if you are doing long-term investing, this is a non-issue.  The difference of hours in being able to trade an ETF during the day vs. only being able to trade a traditional mutual fund at day-end is irrelevant if you are holding the investment for a long time. If you are engaging in day trading, market timing, or other advanced/controversial trading practices, then I suppose it could make a difference. For the way I invest (index funds, long-term, set-it-and-forget-it), ETFs have no advantage over traditional mutual funds.
