International Stock Outperformance Continues

In recent years, investors and advisors have increasingly questioned the need for international diversification. This is likely, at least in part, the result of domestic stocks outperforming their international counterparts for an extended period. Sans a seven-year run of international strength during the mid-2000s, most of the last 30 years have decidedly favored domestic stocks.

More recently, international stocks have finally started to show some signs of life. They began outperforming during 2022, and that relative strength has continued so far this year. Is this a sign of an emerging trend with some staying power? Or will market leadership quickly revert back to U.S. stocks? To answer the question, it is helpful to understand why the U.S. has outperformed for so long in the first place. A recent study published in the Journal of Portfolio Management offers some clues. 

Authored by Cliff Asness (and others) from investment firm AQR, the paper is titled ‘International Diversification – Still Not Crazy After All These Years.’ The authors assert that the U.S. stock market hasn’t necessarily outperformed over the last few decades because U.S. businesses are in some way superior. Instead, it identifies changing valuations as the leading reason. The chart below provides some evidence for their conclusion. 

Valuations of US and Other Equity Markets, January 1980-February 2023

The two blue lines represent the CAPE ratio (a popular valuation metric) for the U.S. and international markets going back to the late 1970s. Like other valuation metrics, a larger number in this chart signifies an investment is more expensive. As you can see, the light blue line (international) became dislocated in the 1980s, rising far above the dark blue (U.S.) line. During that period, the Japanese market had exploded in value. For a brief time, it accounted for roughly 50% of the global market cap and was the most valuable stock market in the world.   

In the long term, valuations tend to revert toward their average level. This is evident between the two blue lines in the above chart. By the early 1990s, the bubble in Japanese share prices popped, and the international CAPE fell back in line with the U.S. CAPE. The two traded roughly in line with each other until the Financial Crisis in 2008. Since that time, another dislocation has formed. This time, it is the U.S. market that has become dislocated. 

The market dislocations of the 1980s, as well as the last 15 years, are more easily observed via the red line. This line, measured by the axis on the right side of the graph, reflects the ratio of the two CAPEs. Any number above 1.0 indicates U.S. stocks are more expensive, while numbers below 1.0 indicate international stocks are more expensive. 

The red line fell below 0.5 by the late 1980s, signifying the U.S. was trading at more than a 50% discount to international markets. The line has been between 1.5 and 2.0 in recent years, signifying U.S. stocks have been trading at a 150 to 200% premium to international markets. According to the study, this change in relative valuation contributed to the vast majority of international’s underperformance over the last 30 years. Simply put, people have been willing to pay an ever-increasing price for an unchanged share of U.S. stock earnings, which is a trend that has not been sustainable historically. 

What implications does this hold for international stocks moving forward? Is there reason to believe the recent outperformance can continue? As mentioned previously, valuations tend to revert to their average over time. If U.S. valuations were to return to historical norms, it would probably favor international market performance.

Week in Review

• According to FactSet, 92% of the S&P 500 has reported Q1 results as of last Friday’s close. The earnings growth rate, blended between companies that have already reported with the estimates for those that have yet to report, is at -2.5% year-over-year. Expectations for the earnings growth rate at the onset of earnings season was -6.7% year-over-year. If earnings end the quarter in negative territory, it will mark the second consecutive quarter of negative earnings and push U.S. stocks into an “earnings recession.” Long-term appreciation in the stock market is dependent on the growth of earnings. To get back to a trajectory of sustainable stock market gains, we will need to see a return of earnings growth.
• Data published last week showed the pace of inflation eased somewhat, though it remains well above the Fed’s target. The Consumer Price Index (CPI) increased 4.9% YoY in April, compared to a 5.0% increase in March. Core CPI, which omits the volatile food and energy sectors, increased 5.5% versus the prior month at 5.6%. The market is currently pricing in a pause on further rate increases at the next meeting, with cuts coming as early as September. While the Fed has suggested a pause may be in the cards, it has consistently pushed back against the notion that it will cut rates in the near term.
• Data to be published this week includes retail sales, an update on the housing market, initial jobless claims, and the Index of Leading Economic Indicators. The market may increasingly pay closer attention to the initial jobless claims data, which is seen as an early warning signal for the health of the labor market. Recent prints have been trending higher, suggesting the tightness in the labor market may finally be easing.
