Quant-driven hedge fund AQR Capital Management is making a bold return to the US mutual fund space after a four-year hiatus, launching a suite of leveraged “portable alpha” strategies targeting taxable investors, according to a report by Bloomberg.

The new lineup – branded as the Fusion Funds – aims to enhance returns by pairing US equity exposure with hedge fund-style overlays such as long-short equity and trend-following, all within a tax-aware framework. The approach frees up capital through derivatives, allowing AQR to layer on active strategies in a capital-efficient structure.

While portable alpha fell out of favour after the 2008 financial crisis, its resurgence reflects investors' appetite for diversifying strategies amid persistent equity market strength and mounting macro uncertainty.

With $500m already allocated to portable alpha across its platform, AQR is positioning the Fusion Funds as a hybrid solution that bridges traditional asset allocation and hedge fund alpha within a mutual fund wrapper—eschewing the more transparent ETF format to protect proprietary strategies.
