The balanced portfolio strategy of allocating 60% to equities and 40% to fixed income generated a highly satisfactory 7.9% annualized return over the last 30 years. Despite the excellent returns earned by investors following this strategic model, the past couple of years have seen a parade of articles with headlines such as “Is the 60/40 Portfolio Obsolete?” and “Is the 60/40 Dead?” Given the central importance of this moderate allocation strategy to investment industry practices, we felt a closer look at the 60/40 portfolio was in order.
In the May Green Book, and again in the May 21st issue of “Chart of the Week,” we discussed the trailing one-year correlation between weekly percentage changes in the S&P 500 and the 10-year Treasury bond yield. Rollovers from high levels in this correlation have signaled most of the important pullbacks in the bond market over the last 20 years.
The 10-year Treasury yield has absorbed the past two months’ worsening inflation numbers by going exactly “nowhere.” Bond investors seem to be all-in on the Fed thesis that the inflation pickup is just transitory.
During the recent consolidation, however, the Treasury yield showed a subtle change in character—one that suggests there might be more inflation paranoia than meets the eye. The 10-year yield’s daily correlation with stock price movements flipped negative, and then plummeted toward a 21-year low.
Bond yields have paused in the last several weeks, but we think it’s likely to be a pause that “refreshes.” Many bond indicators, including the Copper/Gold ratio popularized by Jeffrey Gundlach, suggest yields should be moving dramatically higher in the months ahead.
In recent commentaries, we’ve highlighted the surprising number of U.S. stocks making 52-week lows on both a daily and weekly basis, a sign that the market’s push higher has become more fractured. While pondering the significance of those lows, however, we missed a new 52-week high last Friday in a series we think will be especially critical to the stock market’s near-term fortunes: the 10-year U.S. Treasury bond yield. Specifically, the yield matched its weekly closing high of 3.07% posted on May 18th.
