Japanese Stocks Are Soaring. What’s Behind the Surge.

Japanese stocks hit their highest levels in 31 years on Tuesday. Sure, global markets are in a good mood as investors continue to be bullish about the continued economic recovery. But the global economy is also serving Japan well.

The

Nikkei 225

rose 714 points, or 2.7%, Tuesday. The index settled at 27,568 and touched 27,601 briefly, the highest level the index has hit since 1989.

Other global stocks popped Tuesday, but less so. The

Asia Dow

index closed up 1.6%, the

Hang Seng

Index was up 1%, and the

Stoxx Europe 600

index rose almost 1%. The U.S. stock market has been on a run in the past several trading sessions, but briefly paused Tuesday with the

Dow Jones Industrial Average

down about 100 points in midday trading. While Covid-19 cases continue to rise around the world, fiscal stimulus measures are supporting consumers and businesses, and several biotechs are on the road to mass distribution of vaccines.

But a few recent developments stand out for the Japanese economy and markets. The companies on the Nikkei are exposed to the right geographies and sectors to benefit from the developments.

Fiscal stimulus in key areas around the globe is kicking into gear. The U.S. passed a $900 billion fiscal stimulus bill that will provide aid to individuals and small businesses. South Korea President Moon Jae-in confirmed a third round of direct payments, amounting to 9.3 billion won, or about $8.5 billion, to individuals and small businesses would go out in January. Companies on the Nikkei 225 see on average about 13% of their revenues from the U.S. and 2.8% from South Korea.

That’s more exposed than other indexes around the globe. Companies on the Hang Seng index see 3% of revenues from the U.S. and almost nothing from South Korea. Stoxx 600 companies see almost 20% of revenue from the U.S., but only about 8% of the index is in consumer cyclicals, which stand to benefit as the economy recovers and consumers return to pre-pandemic levels—or higher—of spending. That exposure is another key for the Nikkei: about 18% of Nikkei 225 companies are consumer cyclical companies.

What’s more, Japan is an export-oriented country that wants its currency to be relatively weak to make its exports globally competitive. The yen, however, has strengthened against the dollar and the renminbi, both of which are used to buy Japanese exports. Still, the currency headwind for Japan is outweighed by the brightening global economic environment, Quincy Krosby chief market strategist at Prudential Financial tells Barron’s.

Japan’s recent strength has attracted noteworthy investors. Warren Buffett, for one, made a surprising bet on the country in September.
