World’s Major Economies Fall Behind U.S.

Economies in the U.K. and Japan shrank at the end of last year, underlining the widening gulf between robust growth in the U.S. and more anaemic conditions in the rest of the world.

The decline in activity in Japan came as a surprise to economists and meant that it has slipped in the global rankings of the world’s largest economies behind Germany and into fourth place.

In the U.K., the economy shrank for the second consecutive quarter, the shorthand definition of a recession. The U.K.’s statistics agency Thursday said gross domestic product fell at an annualized rate of 1.4% in the final three months of 2023, compared with a 3.3% increase in the U.S. over the same period.

U.K. consumer spending, the main driver of the U.K. economy, fell over the second half of 2023 even as wage growth outpaced inflation for the first time in two years, boosting consumers’ purchasing power. Japanese consumers, who are still seeing prices rise faster than wages, also cut their spending in the final quarter.

The growth numbers from the U.K. and Japan mirror similarly weak conditions in much of continental Europe and China .

The divergence between the U.S. and the rest of the rich world is in large part a story of surprising U.S. strength . The U.S. grew much faster than economists had expected it would at the start of 2023, while Europe was badly hit by high energy prices from the Ukraine war and rising interest rates. Economists forecast the growth gap will narrow somewhat over the course of the year, but remain wide.

U.S. consumer spending has been more resilient in the face of rising interest rates than in other parts of the world. Government spending in the U.S. has also remained at historically high levels for periods outside of recessions, giving the economy an added boost.

The Organization for Economic Cooperation and Development earlier this month said it expects the U.S. economy to grow by 2.1% this year, while it sees the U.K.’s economy growing by 0.7% and Germany’s economy by 0.3%.

To be sure, the declines in activity in Europe and Japan have been relatively modest and are a reflection of slow-growing economies that by nature fall into contraction more often than those that have a higher sustained level of growth.

And while economic output declined in a number of rich countries as 2023 drew to a close, job markets in Europe and Japan remained tight, as they were in the U.S. As a result, many economists hesitate to describe the U.K. and Japanese downturns as full-blown recessions.

Policymakers expect economies to pick up as inflation ebbs in the months ahead.

“We’re seeing some signs of a pickup,” Bank of England Gov. Andrew Bailey told lawmakers Wednesday.

Japan’s unemployment rate fell to an 11-month low in December, and the Bank of Japan ’s Tankan survey “showed that business conditions across all industries and firm sizes were the strongest they’ve been since 2018.”

Many economists expect the Bank of Japan to end its policy of negative short-term interest rates in either March or April, although the bank hasn’t confirmed that.

“We doubt that today’s GDP figures will prevent the Bank [of Japan] from ending negative interest rates in April,” said Marcel Thieliant , head of Asia-Pacific at Capital Economics.

The decline in its GDP during the second half of the year, and the yen’s weakness relative to the euro, meant that Japan dropped from third place in the global rankings of economic heft when measured in U.S. dollars.

Germany takes over the third-place spot behind the U.S. and China, despite Europe’s largest economy contracting during 2023. Japan lost its second-place spot to China in 2010 .

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.”
