About VOO
Behind VOO stands the Vanguard 500 Index Fund, one of the first index funds for private investors ever. VOO is the exchange-traded share class of that fund. Next to it are conventional fund shares, bought and redeemed directly with Vanguard, and all classes share one portfolio. Vanguard held a patent on this design for many years. Other US providers therefore barely used it; since the patent expired, several have shown interest in similar models.
The structure has a practical effect. When investors redeem conventional shares and the fund has to sell stock, positions with large embedded gains can partly be moved out of the portfolio through the ETF mechanism. For US investors that reduces capital gains distributions; for the holdings it makes no difference.
Unlike SPY, VOO is an open-end investment company under the Investment Company Act of 1940. It may lend securities and invest dividends until they are paid out, which keeps its gap to the index small. Its expense ratio is among the lowest on the market. How closely VOO, IVV and SPY track each other appears in the comparison in the figures section, together with how much of the broader market VOO covers next to VTI.
