Indexed mutual fund vs ETF vs Roth Ira for supplemental retirement savings

Is there such a thing as a “total market index fund”? This seems unworkable. Do you mean a fund that buys every stock listed on (for instance) the Nasdaq market or all markets? Can you name such a fund?

VTI, the Vanguard Total Stock Market index fund. It tracks an index that invests in basically every US-listed stock.

VXUS, the Vanguard Total International Stock index fund. It tracks an index that invests in nearly every stock in non-US developed and non-developed markets.

Well, there’s the Vanguard Total Stock Market Index Fund. It attempts to replicate the behavior of the total market, even if it doesn’t own every stock – only 4,000 according to the NYTimes article mentioned above.

Not to mention getting hit by the bid/ask spread.

There is also the psychological benefit of not being able to day-trade with a mutual fund, if you are prone to that sort of thing.

They’re not that different for what you’re talking about. Pick a decent low-fee one (mutual or etf) and don’t sweat it.

Bid/ask spread, timing of day for trades, etc are all irrelevant concerns for the long term investment you’re talking about.

Spam reported.

If this is being done in a retirement account, then some of what you’ve mentioned doesn’t matter. Yes, mutual funds can distribute capital gains but if it is done inside a retirement account, this doesn’t matter and doesn’t create a taxable event.

Some brokerage companies offer a family of commission free ETFs, this can be helpful, since a disadvantage of ETFs is that you might have to pay commission to buy and sell ETFs, whereas many mutual funds allow you to buy and sell with no charge, although some may have short term redemption fees should you need to sell quickly

Front and back loaded mutual funds are increasingly rare these days and most of the time should be avoided.

During the trading day, the bid/ask/last trade of an ETF will be updated just like a stock, you can also see the indicative value to see how well the ETF is tracking the underlying. This isn’t usually much of an issue like it was with some closed end funds. However, for the average investor seeing the IV or the end of day NAV for a mutual fund isn’t important. You’d likely need a subscription to a Bloomberg, Thompson Reuters, or other such system to even get the IV quote and it is irrelevant to 99% of traders, especially in a retirement account subject to reg T margin.
