  • Stone Ridge Firm Overview

    Stone Ridge focuses on delivering valuable, diversifying return streams sourced from alternative risk exposures – not alpha.  We believe strongly in markets and strongly in the link between risk and return.  We leverage this link to create global opportunities for portfolio enhancement with a family of risk-specific strategies spanning reinsurance, volatility, and alternative lending.

    Powered by a close-knit team – with experience in academia, capital markets, and alternative asset management – our investor solutions facilitate access to and execution of complex strategies, making them accessible and cost-effective.

    Stone Ridge is based in New York with a financial engineering practice in Beijing.
