BlackRock's hedge fund group is urging investors to diversify their hedge fund holdings across multiple strategies in response to faster and more frequent market swings driven by AI-related developments and geopolitical shocks. In its Spring Hedge Fund Outlook issued on Wednesday, the firm said investors should demand clarity on what is truly powering hedge fund returns and where correlated exposures could be building within their portfolios.
BlackRock - the world's largest asset manager with roughly $14 trillion under management - highlighted the need for vigilance where overlapping positions and leverage appear across platforms. The report noted the rising prominence of multi-strategy hedge fund platforms and warned that crowding in particular segments can intensify both volatility and the risk of rapid unwind.
Recent market moves have tested hedge funds. According to leading Wall Street prime brokerages, global hedge funds experienced their worst monthly drawdowns in more than four years last month as volatility triggered by the Iran war hit both equity and bond markets. Several hedge fund strategies underperformed in the first quarter after a blockbuster 2025, the report said.
Responding to the heightened turbulence, funds have pulled back, selling equities for a fourth consecutive month and at the fastest pace recorded in 13 years, according to research from Goldman Sachs cited by BlackRock. Against this backdrop, the firm advises investors to stress test how their hedge fund allocations behave within the context of their full investment portfolios.
The report recommends that investors consider taking profits on riskier positions and seek hedge fund managers that can deliver idiosyncratic returns regardless of broader market direction. BlackRock also observed that a number of asset classes that historically served as havens - notably long-dated government bonds and gold - have not performed in the same protective manner this year.
Since the start of the war, government bond yields have risen as the jump in oil prices stoked inflation concerns, while gold - which had appreciated strongly in recent years - has been used by some investors to offset losses elsewhere, analysts cited in the report said.
"As differentiation across markets increases, the opportunity set for hedge funds expands with it," said Michael Pyle, deputy head of the Portfolio Management Group at BlackRock. The firm encourages investors to probe managers for transparency on exposures and to monitor leverage and concentration risks closely as markets continue to evolve.
