America’s Billionaires Love Japanese Stocks. Why Don’t the Japanese?

TOKYO—Japan’s government is on a mission to make buying stocks hot again.

Many of America’s biggest investors are bullish on Japan. Warren Buffett shared that he increased his investments in Japanese companies during an April visit to the country. Ken Griffin is preparing to reopen an office in Tokyo for his hedge fund, Citadel, and investment banks Goldman Sachs and Morgan Stanley have issued optimistic outlooks for Japan’s stock market.

Japan’s problem is this: There are few signs its estimated 125 million residents share in the excitement.

Burned by dismal returns since the bursting of Japan’s asset bubble in the late 1980s and early 1990s, generations of families here have stashed most of their money in low-yielding savings accounts rather than trying to increase their wealth through the stock market.

Japanese households put an average of just 11% of their savings into stocks and 54% in cash and bank deposits, according to Bank of Japan data released last month. That trails well behind the U.S., where households have about 39% of their money tied up in the market and only 13% in cash and bank deposits, according to Federal Reserve data.

Haruyo Arai, a 62-year-old office worker, began investing in the stock market just last month.

“I was brought up by parents who would say, ‘Don’t dabble in stocks,’ ” she said.

Japanese Prime Minister Fumio Kishida has pledged to double households’ asset incomes, in part by encouraging people to invest in risky assets like stocks. The government is raising caps for Japan’s tax-exempt investment system for small investors, the Nippon Individual Savings Account, with changes set to take effect in January. The Tokyo Stock Exchange has been urging companies to boost their valuations and increase shareholder returns.

Arai cited the upcoming expansion to NISA, along with a desire to save more money for the future, as some of the reasons she decided to begin taking investing more seriously. She has been taking weekend classes at Tokyo-based Financial Academy to learn more about stocks and waking up early every morning to watch a TV news program focused on the economy.

Some believe investors like Arai will prove to be the exception, not the rule. Stocks here haven’t hit a record in decades. There isn’t much buzz among ordinary people about investing in Japanese markets.

“I’ve got the impression that Japanese people don’t really think positively about the desire to make money,” said Takashi Kawaguchi, a 48-year-old office worker who, like Arai, has been learning about investing at Financial Academy.

While the 2023 rally has helped lift Japanese stock indexes to 33-year highs, long-term returns pale in comparison to what an investor would have gotten by investing in U.S. stocks. The Nikkei closed at 32,402 on Friday, still 17% below its record hit in 1989. The S&P 500 has grown more than twelvefold over that time. That has made many investors here turn to foreign markets instead of focusing their bets within Japan.

“The Nikkei might hit 40,000, god knows when,” said Heihachiro “Hutch” Okamoto, foreign equity consultant at retail brokerage Monex. “But most of our investors prefer U.S. stocks.”

To Okamoto’s point, the most popular names traded on Monex daily aren’t Japanese stock indexes like the Topix or Nikkei, brand-name companies like Sony or even the “sogo shosha”—the trading houses that Buffett has invested in. Instead, they are all American names: companies like Nvidia, Tesla, Apple and Amazon.com, as well as funds tracking the S&P 500 and the Nasdaq-100.

And that is just among those interested in investing in the first place. While in past years, everyday investors in Japan made a name for themselves with their forays into the foreign exchange market, the overall trading culture here has been one of hesitation.

“Most people here think investing is very risky,” said Hidekazu Ishida, a special adviser at FinCity.Tokyo, which works with the government and the financial industry to try to boost investment in Tokyo. Being into finance comes off as “kakkowarui,” he added, referencing a word for uncool.

Even some heads of companies are lukewarm about the idea of encouraging more individual investors to buy Japanese stocks.

“I’m neutral about that,” said Takeshi Niinami, chief executive officer of whisky and beverage giant Suntory, when asked if he thought it would be a good idea for more Japanese people to invest in the market. Stock investing is risky, he said. And many Japanese people remain wary of participating in the market, because of the severity of prior downturns.

“I think perhaps increasing interest rates is better for people,” he said.

Wall Street’s hottest trade has gone ice cold.

For years, it paid off to buy stocks that were rising in price—and bet against struggling shares. The momentum trade was especially profitable this year, as investors piled into hot stocks including Micron Technology, Nvidia, Advanced Micro Devices and other artificial-intelligence darlings while wagering against those likely to be hurt by the embrace of AI.

The S&P 500 Momentum Index soared 44% in the second quarter, its best quarterly performance on record, and it surged 133% over the past five years, nearly double the broad market’s performance.

Mega funds and rookie investors alike piled into the trade, some using leverage and options contracts in an effort to amplify their returns, propelling the underlying shares higher.

“It is a self-fulfilling prophecy,” said Matthew Tym, managing director at Cantor Fitzgerald, of the trade.

Suddenly, the trade is a loser. The momentum index has tumbled more than 9% since July 1, lagging behind the S&P 500’s 2.8% gain. The index—which tracks stocks in the S&P 500 based on a “momentum score”—is on track for the biggest quarterly underperformance in 25 years. July was the second-worst month for the momentum trade in around 40 years, according to Bank of America estimates; the only month worse was April 2009, in the teeth of the global financial crisis.

Hedge funds that bought momentum shares while shorting low-momentum stocks suffered even more. At the same time, a basket of the most popular stocks held by hedge funds tracked by Goldman Sachs recorded its biggest one-month underperformance in July relative to the S&P 500 in more than 20 years, according to the bank’s analysts.

Momentum trading is based on a rather simple observation: Investments that go up tend to keep outperforming; those that underperform often remain laggards. This kind of trading might seem too simple a stock-picking strategy to work. Yet it often has.

“For decades, it didn’t take a lot of sophistication to run a momentum strategy and make a decent living at it,” says Agustin Lebron, senior researcher at EquiLibre, a trading firm.

Part of the reason: It takes a while for corporate and other information to spread to various investors, so they slowly build positions, producing buying momentum.

“A huge pension fund can’t flip around its positions in a day,” says Lebron. “Behavioral biases also account for some of the effect, as well—people tend to sell their winners too early and hold losers too long.”

Fans of the strategy point to the human tendency to extrapolate from past results—and chase investment returns—noting that momentum patterns have been evident in markets for decades, even centuries. They also say that some of the worst months for momentum strategies are during longer periods of outperformance.

Some have been doing the trade by buying the strongest investments in a sector while shorting the weakest; others lean in to rising markets or asset classes. Still others use a quantitative approach or turn to banks or others who sell ways to make distinct wagers on momentum as a “tradable factor” or a “thematic basket.”

The fans remain believers. “Any strategy has disappointing periods,” says Antti Ilmanen, global co-head of the portfolio solutions group at AQR Capital Management.

The surge in Moderna and other biotech stocks helped crush the momentum trade. These shares were among the most heavily shorted in recent years, but positive news on a cancer vaccine from Moderna and Merck sent those stocks flying, crushing some quant and other hedge funds. Moderna is up around 150% so far this month.

These traders had an especially rough day on Aug. 19, which Goldman Sachs told its clients was the worst day for “systematic long-short managers” in more than two years. About half of the losses were because of momentum trades, the bank said.

Some traders have begun to short, or bet against, the very stocks that propelled the momentum trade earlier this year. Net short positions in futures tied to the Nasdaq-100 index among speculators recently climbed to some of the highest levels of the past two decades, according to data from the Commodity Futures Trading Commission.

The about-face is a sign of how markets have become more treacherous for investors, even as indexes keep climbing. Part of the issue: the recent meltdown of Situational Awareness, a hedge fund that had piled into some of the most popular momentum shares, including chip stocks. After a period of market tumult, Nvidia shares rocketed almost 9% after its earnings, showing how quickly sentiment can shift.

Some investors say the run-up in share prices driving tech stocks higher reminds them at times of the dot-com frenzy decades ago.

Mike Ogborne, the founder of San Francisco-based Ogborne Capital Management, said he has grown more cautious on technology stocks and is keeping more of his portfolio in cash than he typically does.

And he is nervous about the surge in spending by technology giants and quarterly capital expenditures that keep rising.

“It is a little bit like Cinderella and the clock striking midnight. You don’t know when midnight is going to come around,” Ogborne said. “They don’t send a memo around telling you when the capex cycle is over.”
