Japan’s Mid-Quarter Market Turmoil Ends in Recovery for Fast-Growing Small Caps

An unexpected interest-rate increase from the Bank of Japan helped ignite a market firestorm during the third quarter.

The central bank’s decision in late July caused a swift appreciation in the yen, a currency shift that disrupted the widely used strategy known as the yen carry trade, where investors borrowed at low Japanese rates to purchase higher-yielding foreign assets. The rapid unwinding of these positions, combined with weaker US economic data and disappointing earnings from US technology giants, culminated in a 12% drop in Japan’s Nikkei index on August 5, while expected volatility in the US equity market spiked to a level not seen outside of major crises.

Markets recovered quickly, though, and Japan ended the quarter as the second-best performing region for small-cap stocks. As the chart above shows, the yen also topped currency returns.

For several quarters, Japan has been a particularly challenging market for investors in quality growth small companies, as stocks of cheaper, low-quality businesses tended to outperform. However, another market development in Japan in the third quarter was that style patterns reversed, with stocks of faster-growing, more expensive companies leading returns. The charts below depict the spread between returns for the fastest- and slowest-growing, highest- and lowest-quality, and least and most expensive small caps by region for both the third quarter and trailing 12 months, based on Harding Loevner’s proprietary growth, quality, and value quintiles.

Although it’s too soon to know whether Japan’s value rally is finally over, the third quarter provided a welcome reprieve.

Why Own International Stocks?

For more than a decade, equity returns in international markets have trailed those of the US. There are various possible explanations, but a central one is that the US, after first staging a faster recovery from the global financial crisis, has tended to produce stronger earnings growth in the years since. Meanwhile, from an international perspective, everything from a strong dollar to geopolitical conflict to volatility in emerging markets to China’s economic slowdown have weighed on relative returns. It also doesn’t help that the arrival of ChatGPT, and the enthusiasm and competition it has inspired for generative artificial intelligence technology, has lately encouraged an almost singular focus on a handful of US tech stocks—out of nearly 2700 index constituents, a mere 0.2% of the companies in the MSCI ACWI Index.

Some investors look at the difference between international and US returns and, expecting that current conditions will persist, wonder what place non-US equities have in a portfolio today. But while it’s easy to fall into that line of thinking, history suggests it is likely wrong. The relative performance of US and non-US stocks has historically been a cyclical phenomenon, and as the chart below shows, their indexes have regularly swapped between leader and laggard over the past 50 years.

Growth Is Beating Value in the US. Will International Follow?

Non-US markets have underperformed the US for quite some time. This has been exacerbated lately by their diverging style factors.

As seen in the chart above, investors largely favored value stocks as the global economy began to reemerge from the COVID-19 pandemic following emergency-use authorization of the first vaccine in late 2020. This headwind for growth stocks has been most significant, and enduring, in international markets. For example, the MSCI All Country World ex US Growth Index lagged its value counterpart by nearly 30 percentage points in the three years through October 2023. But while the value rally has continued outside the US, 2023 saw investors reembrace US growth stocks despite their relatively high valuations.

Valuation is in the Eye of the Beholder

The structure of sports leagues in the United States differs from those seen elsewhere in the world. Most importantly, American sports teams compete annually against pretty much the same opposition. The composition of leagues such as the NFL or NBA is largely static, with new franchises entering only rarely and with the agreement of the owners of other teams. The same holds true for various minor leagues, which operate in conjunction with the largest professional leagues, but whose teams don’t move between levels of the sport.

In UK soccer, the sport with which I am involved, in contrast, the league is composed of linked divisions arranged in a hierarchy where membership of each division changes at the end of every season—based on merit, so that the top few teams in each division move up in the hierarchy, and the bottom few clubs move down. The drama around the joy of promotion to a higher division and the misery of relegation to a lower one is part of what makes the sport so compelling; for fans (and owners) of clubs involved in the battle to win one or avoid the other, the chase can be both thrilling and terrifying.
