Investors' holdings of exchange-traded funds have just passed the $2 trillion mark globally, showing powerful growth at a time when mutual funds are struggling to show any, says a new BlackRock ETP Research report.
There are good reasons ETFs have grown faster than established mutual funds, most importantly their success in beating traditional funds on fees. But this doesn't mean your mutual fund has become obsolete.
Mutual funds still hold $20 trillion globally, and there are compelling reasons to own them. "There is plenty of room for both kinds of funds," says Jeff Tjornehoj, head of research at Lipper. "The growth of ETFs is not necessarily coming at the expense of mutual funds. They are really expanding the market with new alternatives."
Here are five reasons ETFs have won people over so rapidly—and reasons you might still want to keep your mutual funds:
1. ETFs offer lower fees than mutual funds or owning stock baskets. The cost of investing in exchange-traded funds is between 0.1 percent and 1 percent a year, well below the 0.5 percent to 3 percent charged by managed funds. That difference can add up to tens of thousands of dollars over the life a retirement plan. ETF fees are lower because their structure requires less cost to manage.
Others costs, some hidden: You pay a commission to buy an ETF because it acts much like a stock but owns a basket of funds or other assets. When the value of the ETF fails to follow its benchmark index, it can add additional costs for people buying or selling. The ETF itself has a bid and ask spread, meaning you may might overpay when you buy if demand is strong, or lose money when you sell if it is weak.
2. ETFs are more transparent and open than mutual funds. ETFs are quoted on exchanges and each day, investors can see a complete list of stock holdings of ETFs on various websites. Mutual funds give only their net asset value each day and they list stock holdings only at the end of the fiscal quarter on a delayed basis.
Contrarian view: ETFs list their holdings, to be sure. But they can be involved in many opaque transactions to generate income, such as pay for order flow and stock lending. Not all of it goes to boost the value of the ETF shares.
3. You are investing in an index for the long term. Financial advisers often prefer ETFs because they are an easy, low-cost way to get their clients market exposure compared to stocks or mutual funds. With extremely low annual fees of just 0.05 percent to 0.1 percent, you can own shares of the entire Standard & Poor's 500 index with the SPDR S&P 500 ETF (SPY), iShares Core S&P 500 (IVV), and the Vanguard S&P 500 ETF (VOO).

Short term or long term: You might be investing for the long term, but not everyone is. ETFs are a favorite of fast-trading investors. Even the founding father of index fund investing, John Bogle, has been a critic of ETFs because they were designed to trade quickly. This creates short-term price stress and risks for every holder, regardless of investment philosophy. Regulators have also been looking at systemic risks in high-volume ETF trades and the volatility of some exotic new offerings.
4. ETFs don't waste your money on fund managers who most often fail. Since studies show that more than half of managed funds fail to meet their benchmark averages, like the S&P 500 or the Nasdaq index, why pay to lose? Or worse, there is evidence that mediocre fund managers aim to merely "shadow" an index, so you are paying fees to get below-average returns.
