A record outflow from one of Vanguard Group’s biggest exchange-traded funds is stirring speculation over who was behind it and why.
More than $7 billion was pulled from the $172 billion Vanguard S&P 500 ETF (VOO) on a single day this week, according to data compiled by Bloomberg, about 4% of the fund’s assets.
But trading volumes were below the one-year average and there were no obvious outsized transactions, while the U.S. equity benchmark rose on the day — making a mass exodus less appealing.
It’s all leading to a theory that a major holder of the fund executed a large over-the-counter trade.
“We think the redemption didn’t show up because it was an outsized primary market sale,” said Eric Balchunas, a Bloomberg Intelligence ETF analyst.
Rather than shopping for a tie at a store, “this is like someone going straight to the tiemaker, and that’s rare since most ETF usage is smaller investors,” he said.
When cash flows into an ETF, a market maker known as an authorized participant gives the issuer more of the fund’s underlying assets in exchange for new shares to meet demand. When money is being taken out, the process works in reverse.
Ordinarily an investor buys or sells their shares on an exchange. But instead of selling on the open market, they could hand them directly to an AP, who can redeem them with the issuer in return for the underlying assets.
Those assets can then be sold down by the AP or passed on to the investor to hold or sell.
