Much has been talked about regarding the failure of the 60/40 portfolio last year, but Vanguard analysts recently suggested that investors shouldn’t abandon a balanced portfolio strategy. Roger Aliaga-Diaz, portfolio construction head for Vanguard, and his team said in a recent note that “A balanced portfolio still offers the best chance of success.” Aliaga-Diaz noted that while the negative correlation between stocks and bonds broke down last year, “longer term, however, the data support balanced portfolios.” The firm noted that “The policy response to higher and more persistent inflation and the subsequent repricing of risk in global capital markets has led to a dramatic shift in our time-varying asset allocation (TVAA) outlook.” The TVAA looks to harvest the risk premiums for which the Vanguard thinks there is modest return predictability. Based on the firm’s current outlook, Vanguard’s optimal TVAA portfolio “calls for a 50/50 stock and bond split, and favors bonds and emerging markets.” Specifically, Vanguard’s TVAA allocation suggests 30% U.S. stocks, 20% international (divided equally between developed and emerging markets), 22% international bonds, and 27% U.S. fixed income (mostly in U.S. intermediate credit bonds). The firm noted that the interest rate tightening cycle in 2022 raised its expected bond return forecasts by more than the equity sell-off raised expected equity returns.

Finsum:While the 60/40 portfolio failed last year, Vanguard believes a balanced portfolio still offers the best chance of long-term success and recommends a 50/50 stock and bond split.
