Rethinking Diversification in Investment Portfolios

This technical report discusses the changing dynamics of stock-bond correlations and their implications for investment portfolios. It outlines how the correlation flipped to positive in 2021 after being negative for two decades, affecting portfolio expectations. The report details the historical behavior of stock-bond correlations and the macroeconomic factors influencing these changes. It emphasizes the need for alternative diversifier strategies, such as active long volatility and cross-asset trend strategies, to manage downside risks effectively. These strategies can complement traditional fixed income investments, particularly during periods of heightened equity volatility. The report also presents findings on how these alternative strategies can enhance portfolio performance when stock-bond correlations are positive. By systematically capturing price movements across asset classes, these strategies can provide defensive properties in equity downturns, thereby improving overall portfolio resilience. The document concludes with a discussion on the importance of adapting investment strategies to evolving market conditions.
