The 60/40 strategy, known as a balanced portfolio, has been hit by rising bond yields — which means falling fixed income prices, as well as a sinking stock market.
"The future is brighter for the 60/40," said Omar Aguilar, CEO and chief investment officer of Schwab Asset Management.
"The correlation will come back to the normal levels, or the historical levels that you normally have between equities and fixed income," Aguilar said.
Schwab's Aguilar advises against chasing yields in fixed income, but instead maintaining a balanced approach between credit and duration.
In fixed income, the firm currently has a bond duration of four years, down from its previous seven-year duration.
