Here are a couple of links you may find helpful. A google of "ETF redemption units" or "ETF creation units" will bring up many more links.Thanks, Michael B, for that info. Didn't know any of it even tho I occasionally wonder about funds vs ETF and read articles about them. Do you by chance have a link to a VG (or other) article about that? Do you have a brief explanation of how ETF funds can exchange shares w/o recognizing CGs?
Before you mentioned that, I thought that it was because those 3 funds that pb4uski mentioned are passive index funds and I thought one of their attributes is that they have minimal CG distributions.

An Inside Look At ETF Construction
Basically, during the day, the market price of the ETF diverges slightly from the price of the basket of securities it represents. Securities law allows an authorized investor to buy (or sell) the ETF but actually take delivery (or provide) the underlying stocks, so when, during a market sell off the price of the ETF falls, say, 0.5% below the asset value (NAV), an institutional investor buys the ETF but actually takes delivery of the basket of individual stocks. They turn around and immediately sell the stocks, and pocket that 0.5% difference, minus transaction cost. This is how the market keeps the price of the ETF close to the net asset value of the stocks. This transaction is carried out directly with the ETF creator, in this case, Vanguard.
The critical aspect is that, when Vanguard carries out this transaction, the IRS allows them to give the institutional investor any specific share of stock in their inventory but not record it as a capital gain or loss. Vanguard, of course, will therefore transfer the shares with the lowest cost basis, which are also the highest unrealized profit. That way, Vanguard is constantly exchanging equities for cash or ETF units, and always transferring out the stocks with profit.
Contrast this to a regular mutual fund, when it sells individual stocks it must record the transaction as a gain or loss, and the mutual fund holder now has a taxable gain, even if they didn't sell.
Vanguard us the only company that has some mutual funds that are also ETFs. This is a real advantage for the fund holder.
A poor explanation for sure. For this to work well, the ETF needs a good amount of volume, this is why it's important to avoid ETFs that don't trade a lot.
