Bridgewater, one of the world’s largest hedge funds, is joining forces with State Street’s asset management arm to tap retail investors in the latest effort by money managers to look for new customers beyond their traditional strengths.

The partnership announced on Tuesday will start with an exchange traded fund that will track one of Bridgewater’s best-known strategies. State Street Global Advisers has filed plans with the US Securities and Exchange Commission for an “All-Weather” ETF, which seeks to profit in all types of market conditions by holding a wide range of assets.

If approved by the regulator, it will be sub-managed by Bridgewater using its “risk parity” strategy, which uses leverage to weight assets by expected volatility. Once it starts trading, the ETF could offer other investors new insights into Bridgewater’s famously secretive methods.
