A Positive Stock-Bond Correlation Is a Terrible Reason to Add More Equity Risk to Your Portfolio

Stocks and government bonds have recently moved together more often, which weakens one of the most reliable sources of diversification in traditional portfolios. That shift matters because when both assets fall at the same time, balanced allocations can experience sharper drawdowns than investors may be used to.

The key message is not to abandon diversification, but to rethink where it comes from. Investors may need broader sources of resilience, including assets that respond differently across inflation and growth regimes.

This also raises the bar for portfolio construction and risk management. In a more correlated world, simple assumptions can lead to false comfort and weaker outcomes.

For advisors and investors, the opportunity is to build portfolios that are less dependent on one relationship holding forever. The main risk is relying on outdated playbooks just as market conditions are changing.
