Hedge funds that rely on old-fashioned stock picking had a standout June, but their success came with a familiar risk: they were all piling into the same trades. According to a Goldman Sachs client note reported by Reuters, discretionary hedge funds that select stocks based on company fundamentals returned 4% in June and roughly 17.4% for the first half of the year. The gains came even as the Roundhill Magnificent Seven ETF, which tracks the biggest tech giants, fell 9% during the month.
How hedge funds beat the market
Goldman's analysis showed that fund managers didn't just pick the right individual stocks. They also ran higher overall exposure to the market and leaned into themes that were already working, including momentum strategies and a tilt toward healthcare stocks. Momentum investing means buying stocks that have recently risen and selling those that have fallen, a strategy that can amplify gains in a rising market but also increase vulnerability to sudden reversals.
The strong performance is a reminder that hedge funds can still generate solid returns even when the most popular stocks—the so-called Magnificent Seven—are struggling. For everyday investors, it highlights the value of diversification: while the S&P 500 is heavily weighted toward a handful of mega-cap tech names, hedge funds were able to find profits elsewhere, particularly in healthcare and other sectors.
The crowding risk
Goldman's report also flagged a potential downside. When many funds pile into the same trades, it can create a crowded market that works well until it doesn't. If volatility spikes, funds often hit internal risk limits, and their prime brokers—the banks that provide trading leverage and securities lending—may tighten financing terms. The fastest way for a fund to reduce risk is to cut its gross exposure, meaning it sells long positions and buys back short positions. When many managers do this at once, price moves can become more correlated and abrupt.
Goldman's own list of "pain points" showed where the risks are concentrated: losses linked to volatility spikes, short positions getting squeezed, and country-level crowding, such as in South Korean equities. The firm also noted that systematic funds, which rely on computer models rather than human judgment, performed less well in June. Winton, a systematic investment firm, pointed to choppy trading in mega-cap US stocks and China as a reminder that sudden market reversals can overwhelm rule-based positioning.
What it means for investors
For the average investor, the hedge fund performance is a useful case study in how professional money managers navigate a market that is increasingly dominated by a few big names. The fact that hedge funds were able to generate strong returns without relying on the Magnificent Seven suggests that opportunities exist beyond the largest tech stocks. However, the crowding risk is a cautionary tale: when everyone is on the same side of a trade, the exit can be messy.
Investors should also be aware that hedge fund returns are not always what they seem. A 17.4% year-to-date gain looks impressive, but it can mask the fact that many funds are effectively riding the same wave. If that wave breaks, the sell-off can be swift and broad. Goldman's report noted that the strong quarter came with "air pockets"—periods of sharp declines in certain assets, such as the Magnificent Seven ETF's 9% drop in June.
For those with exposure to hedge funds through pension plans or other institutional investments, the key takeaway is that past performance is no guarantee of future results, especially when that performance is built on crowded trades. The broader market backdrop also matters: if volatility rises, the leverage-and-liquidity chain can flip quickly, forcing funds to cut exposure and potentially amplifying market moves.
In the meantime, the hedge fund industry's strong first half is a reminder that active management can still deliver, even in a market dominated by passive index funds. But as Goldman's analysis shows, the path to those returns is not without risk.
