After 34 years, Japan’s Nikkei 225 completes a roundtrip

United States

The Nikkei 225 — an oddly constructed index covering the top 225 Japanese companies — is back at levels not reached since 1989.

The Nikkei 225 JP:NIK rallied 2.2% Thursday to finish at 39,098.68, taking out the Dec. 1989 peak of 38,916 in the process.

“Although the most recent push to these levels has been rapid, we do not view this as a mountaineering ascent to a peak where the next phase is how to manage the descent,” said Morgan Stanley strategists led by Jonathan Garner, who back in 1989 would type up Eurobond closing prices from London and fax them to Tokyo.

The Morgan Stanley analysts noted that profit from the Prime Section-based group of companies has jumped 20% year-over-year. Data from Societe Generale meanwhile shows Japan is the only country where earnings per share estimates for this year and next are actually rising.

That’s impressive considering that there isn’t a clear driver for profit growth like artificial intelligence that has propped up the likes of Nvidia NVDA, -2.85% and Super Micro Computer SMCI, -6.78%. And oddly enough, many of Berkshire Hathaway’s holdings including Mitsubishi 8058, +3.04%, Mitsui 8031, +1.95%, Marubeni 8002, +2.15% and Sumitomo 8053, +1.44% — which all have been stellar investments for the Warren Buffett-led company —are the biggest drags on Japanese profits.

Japan has pushed companies to adopt corporate governance reforms, which has led to record-high stock buybacks, while the country’s central bank is considering exiting its negative interest-rate regime amid signs it may be escaping deflation.

Analysts do note that the Nikkei, like the Dow Jones Industrial Average, is a price-weighted equity index, which produces some unusual results. The biggest weight in the index, Fast Retailing 9983, +3.15%, is actually the seventh largest company by market cap; the biggest company, Toyota Motor TM, +0.14%, is number 15 in the Nikkei by weight.

The more broadly, and one could say normally, constructed Topix JP:180460 is still about 8% away from its peak. U.S.-based investors would’ve been better off staying at home over the last 52 weeks, with the S&P 500 SPX up 24%, compared to a still impressive 20% rise for the iShares MSCI Japan ETF EWJ.

There are of course risks.

Japanese companies, which have adjusted to a feeble domestic economy, are highly exposed both to the U.S. — not a problem right now — and China, which is struggling with a Japan-like debt overhang. There’s also the yen USDJPY, +0.10%, which could surge in value if the Bank of Japan lifts interest rates, possibly making Japan’s exporters less competitive.

Back in the 1980s, Japanese companies were on top of the world — according to Reuters data, representing 45% of global stock market value at their peak, versus just 6% now.

That was captured in pop culture. Die Hard, for instance, was set in the U.S. subsidiary of a Japanese company, which did enough business to have some $ 640 million of bearer bonds in the vault. Rising Sun, based on the Michael Crichton novel, was a darker assessment of Japanese corporate culture, which involved a subplot of a U.S. senator being bribed to push through the acquisition of a U.S. company.

How times have changed is reflected in the relative lack of controversy over Nippon Steel’s 5401, +0.62% planned acquisition of U.S. Steel X, +0.85%. Those companies are sponsors of Politico’s daily political newsletter to Beltway elites.
