In this article, we will take a detailed look at 8 Worst Performing Mutual Funds in 2024.

Mutual funds with exposure to large and mid-cap US companies were big winners in 2024 as the overall US equity market remained bullish for the second year in a row. As the artificial intelligence boom drove markets higher, some mutual funds outperformed the overall market, and the S&P 500 gained 24%.

Large-cap growth funds were up by almost 30% for the year. That was the highest gain of all the main fund categories. Small-cap growth funds were up by an average of 14.7%, as mid-cap growth funds surged 16%.

According to LSEG, the average U.S. stock fund increased 17.4% overall in 2024, including a 1.2% gain in the fourth quarter. Even though the 2024 performance didn’t quite match the previous year’s 21% gain, stock funds have now experienced impressive growth for two consecutive years. The main drivers of the gains were the U.S. economy’s recovery and investors’ expectation that the Federal Reserve would cut rates.

The explosion of artificial intelligence and the technologies supporting its adoption and growth also had a hand in driving stocks, thus helping to improve the performance of funds that finished at the top. Increased holdings from the “Magnificent Seven” technology stocks, such as Nvidia and Meta Platforms, allowed U.S. large-cap growth funds to maintain their dominance in the mutual fund market.

“It’s hard to outperform large-cap when you’re in small-cap and you don’t have the Mag Seven,” says Brian Smoluch, a longtime co-manager of the small-cap growth fund.

On average, foreign stock funds were unable to keep up with their U.S. counterparts. The fourth quarter’s 7.3% thrashing held back the category’s 4.8% gain. On the other hand, bond funds saw a modest increase for the year. Investment-grade debt funds recovered from a nearly 3% drop in the fourth quarter to end the year up 1.8%.

Investors remain bullish on mutual funds focused on bonds and U.S. stock funds. According to estimates, investors pumped a net $177.2 billion into U.S.-stock mutual funds and exchange-traded funds (ETFs) in 2024. Only $11.6 billion was allocated to international stock funds.

Although the frenetic buying that occurred earlier in the year subsided as the year came to a close, bond funds fared better in the flows than stock funds. According to ICI estimates, investors poured a net $488.6 billion into bond funds for the entire year 2024 in anticipation of the Fed’s rate-cutting actions, which started in September. However, the buying slowed, and estimates indicate that December ended as a comparatively weak month for flow data.
