The whole point of actively run funds, their proponents say, is that a living, breathing fund manager has a better chance of sussing out great investment opportunities than an exchange-traded fund, which just blindly tracks an index. Indeed, that's one of the reasons actively managed funds have higher fees than ETFs -- to pay for all that expert guidance.
So it might come as a shock to some investors that the top holdings of several major stock mutual funds are actually ETFs.
Mutual funds have to equitize cash, either from inflows or dividends, or just because they sell something and don't see anything in the market they want to buy. They used to buy futures, where margins could climb sky high; now they use ETFs. It allows them to get quick, cheap exposure to the market.
You put the money to work in an index product, and then when you get a better idea, you buy some stocks and sell off that index position. It's the best way to handle "cash management."
And here's the dirty secret: everyone does it. In fact, you'll notice it frequently happens around the last day of the quarter, depending on what inflows, outflows and dividends different mutual funds receive.
