Quick Clips: The Stock/Bond Correlation

The relationship between stocks and bonds has long been a crucial measure for portfolio management in traditional portfolios. For the past two decades, the stock/bond correlation (SBC) has been consistently negative, and investors have been able to rely on their bond investments for portfolio protection when equities sell off. However, macroeconomic changes – like heightened inflation risk – could push this key asset allocation input into positive territory.

With reduced diversification between stocks and bonds, we think investors should re-evaluate their overall portfolio allocations. In this challenging environment of high valuations, monetary policy tightening and heightened macroeconomic risks, alternatives may be a good solution to help manage risk and enhance portfolio returns.

So what is the longer-term outlook and how can investors prepare? While the SBC has trended upwards, a prolonged shift would require longer-term inflation uncertainty coupled with additional shocks or monetary policy errors. This scenario remains a tail risk for investors, and we believe that awareness of the SBC drivers and investment implications, as well as rethinking a portfolio’s diversifiers will be critical to navigating a changing SBC.

The SBC outlook is one of several tail risks for investors (00:42):
