Dalio Patched All Weather Fund’s Risk as U.S. Bonds Tumbled

As the bond market plunged in late June, Ray Dalio convened the clients of Bridgewater Associates LP, the world’s largest hedge-fund manager, to tell them that a fund designed to withstand a broad range of market scenarios was too vulnerable to changes in interest rates.

Bridgewater, citing months of study, said it had underestimated the interest-rate sensitivity of various assets in its All Weather fund and was taking steps to mitigate the risk, according to clients who listened to or read a transcript of the June 24 call. By the end of the month, the Westport, Connecticut-based firm had sold off enough Treasuries and inflation-linked bonds to help reduce the fund’s most rate-sensitive assets by $37 billion, according to fund documents and data provided by investors.
