The $4.5 trillion hedge fund industry demonstrated resilience in January 2025, with major multistrategy funds posting positive returns despite market turbulence triggered by geopolitical tensions and significant artificial intelligence breakthroughs. The month was marked by the emergence of DeepSeek, a Chinese AI company that sent shockwaves through tech markets and contributed to a mid-January sell-off of major technology stocks.
Walleye Capital led the pack with an impressive 3.6% gain in January, managing $5.8 billion in its multistrategy fund. Close behind were industry giants Balyasny Asset Management ($22 billion AUM) with a 2.5% return and Schonfeld Strategic Advisors ($12 billion AUM) posting 2.2% gains. These returns came during a period when the S&P 500 finished up 2.7%, but AI-sensitive tech stocks experienced significant volatility.
The DeepSeek breakthrough particularly impacted semiconductor stocks, with Nvidia dropping more than 10% for the year after a blockbuster 2024 performance. However, other tech giants including Meta (Facebook’s parent company) and Amazon managed to post positive returns for the year, highlighting the selective nature of the AI-driven market correction.
Multistrategy hedge funds, which have become the preferred investment vehicle for limited partners due to their ability to navigate volatility, largely weathered the storm. ExodusPoint gained 2%, while Ken Griffin’s Citadel posted 1.4% returns, and Millennium Management added 0.5%. Citadel’s Tactical Trading strategy, which combines quantitative and fundamental equity portfolios, performed particularly well with a 2.7% gain, demonstrating the value of diversified approaches during AI-driven market disruptions.
Not all managers succeeded in the turbulent environment. Alan Howard’s Brevan Howard experienced mixed results across its $35 billion in assets, with the flagship Master fund declining 2.9% while the Alpha Strategies fund gained 1.5%. The divergent performance highlights how different strategies responded to the AI news and broader market conditions.
The January performance underscores how artificial intelligence developments are increasingly becoming market-moving events, with the ability to trigger sector rotations and volatility that even the most sophisticated hedge funds must navigate carefully.
Key Quotes
January markets were choppy, thanks to President Donald Trump’s trade and immigration policy plans and a breakthrough from Chinese artificial intelligence darling DeepSeek.
This observation from the article highlights how AI developments, specifically from Chinese company DeepSeek, have become significant enough to rank alongside presidential policy decisions as major market-moving events, demonstrating AI’s elevated importance in global financial markets.
The chipmaker is down more than 10% for the year after a blockbuster 2024, though other tech giants are up for the year, including Facebook parent Meta and Amazon.
This statement reveals the selective nature of the AI-driven market correction, with semiconductor companies bearing the brunt of concerns about AI competition while diversified tech companies with AI applications maintained positive performance, suggesting a shift in how investors value different parts of the AI ecosystem.
Our Take
The January hedge fund performance data tells a compelling story about the maturing AI investment landscape. The DeepSeek breakthrough functioned as a stress test for the market’s AI thesis, and the results are instructive: pure-play AI infrastructure suffered while diversified tech companies held firm. This suggests investors are recalibrating their understanding of where AI value will ultimately accrue. The success of multistrategy funds in navigating this volatility demonstrates that AI developments now require sophisticated, multi-faceted investment approaches rather than simple sector bets. Most significantly, the fact that a Chinese AI company could trigger such market movement signals that AI competition is truly global, and Western investors can no longer assume American dominance. This geopolitical dimension of AI investing will likely define market dynamics throughout 2025 and beyond.
Why This Matters
This story reveals how AI breakthroughs are becoming major market catalysts that can trigger billions in capital flows and test even the most sophisticated investment strategies. The DeepSeek announcement’s ability to cause a significant tech sell-off, particularly in AI infrastructure stocks like Nvidia, demonstrates that AI development is no longer just a technology story—it’s a systemic market force.
For the hedge fund industry, this represents a new era where AI developments must be monitored as closely as Federal Reserve decisions or geopolitical events. The fact that multistrategy funds largely navigated this volatility successfully suggests that diversification remains crucial when AI news can rapidly reshape market leadership.
The selective impact—with Nvidia down while Meta and Amazon remained positive—indicates that investors are becoming more discriminating about AI investments, moving beyond the broad enthusiasm that characterized 2024. This maturation of AI investing has profound implications for how capital will flow to AI companies and infrastructure providers going forward, potentially favoring companies with proven AI monetization over pure-play infrastructure bets.
