Most of the funds run by each of the four largest banks in the business — Goldman Sachs, Morgan Stanley, JPMorgan Chase and Wells Fargo — have underperformed their basic benchmarks over the last 10 years, according to analysis of industry data done for The New York Times by Morningstar. And that does not include the funds that went out of business because of poor performance.
While some of the banks have seen better performance over more recent periods — in which the stock markets have been steadily rising — the investment products created by Wall Street's biggest name, Goldman, have been particularly disappointing, with only 12 percent of the bank's mutual funds outperforming their relative benchmarks over the last 10 years, and 35 percent over the last five years.
"It's a good business for them — but that doesn't mean it is a good investment," said Larry Swedroe, director of research at Buckingham Asset Management. Mr. Swedroe began his career on bank trading desks but has become an advocate for more passive investment strategies.
There is a wide body of research showing how hard it is for actively managed mutual funds — like the ones run by the banks — to outperform low-cost funds like the ones that invest in a benchmarked index of stocks and bonds.
The banks have suggested in marketing materials that their investing prowess differentiates their offerings from the pack. But the relatively high fees that banks charge for their mutual funds subtract from the ultimate returns and make it harder to compete against their most successful competitor in recent years, the giant fund manager Vanguard, a company that prides itself on offering low-cost funds.
Thanks in large part to its low fees, 80 percent of Vanguard's actively managed funds survived and outperformed a majority of peers during the last 10 years. At Goldman, only 24 percent did so, and only 30 percent of Wells Fargo funds did.
A Morningstar analyst for Goldman funds, Laura Lallos, said, "We do not consider their overall long-term performance to be a success any way you look at it."
The underwhelming performance of most funds is rarely mentioned when the banks discuss the big business opportunity they are going after in the so-called asset management sector.
When Goldman's chief financial officer, Harvey M. Schwartz, spoke about Goldman's "strategic initiative to grow asset management" on his most recent call with investors, he said that the "team's done a great job."
For Goldman's bottom line, the business has indeed been doing well. During 2014, the company's funds drew $73 billion of new money from investors, increasing revenues in the investment management division by 11 percent over the previous year. Goldman has nearly doubled the number of mutual funds it has offered over the last decade.
When Goldman and other banks discuss the performance of their funds, they tend to use statistics that are weighted by how much money is in each of the funds at the time of measurement. On this basis, Goldman says that 75 percent of its clients' money is in mutual funds that have been in the top half of competitors over the last five years.
"There are many ways to determine the performance of mutual funds, but we choose to consistently focus on figures that we believe most accurately reflect the investment performance that our clients experience," said David Wells, a Goldman spokesman.
Darin Oduyoye, a spokesman for JPMorgan, says that it, too, chooses to look at fund performance based on where client money is at the current moment. He said that looking at the absolute number of funds that have underperformed is "misleading and does not reflect where our clients are actually invested."
The approach used by the banks, though, is not favored by researchers because it skews the figures to where money is now, even if the money just entered top-performing funds and did not experience recent gains. Studies have shown that investors tend to put money into investments after periods of outperformance and then miss that outperformance.
Goldman Sachs and Morgan Stanley have acknowledged that their funds, broadly, have not been stellar in the past, but both companies have recently made big efforts to reshape their teams and improve the returns. That has helped increase the number of funds at both companies that have beaten their benchmarks over the last three and five years, though the outperformance slipped again during the last year.
