China’s Neighbours Shouldn’t Cheer On Its Slowdown

China’s economic troubles have so far been a boon to other Asian markets. But if the world’s second largest economy continues to turn sour, things could start to look uglier for them too.

Major Asian stock markets have been doing well in 2023. Japan’s Topix index has gained 24% this year while Taiwan’s Taiex index has risen 18% and Korea’s Kospi is up 15%. That is in contrast to Chinese stocks: the MSCI China index has dropped 6%, despite a strong start of the year.

There are some fundamental reasons why Asian stocks outside of China have gone up. Buybacks and dividends are rising in Japan, while Warren Buffett’s endorsement gave the market another push. The hope of an eventual rebound in the semiconductor industry has lifted stocks in Taiwan and South Korea. But these markets also benefited from foreign investors fleeing Chinese stocks: markets such as Japan and South Korea have seen foreign inflows in recent months. Some multinationals have also been migrating manufacturing out of China and into other Asian countries to diversify their supply chains.

However, Goldman Sachs has noted that correlations between China and other markets in the region have risen lately, indicating potential concerns of spillover.

China is the top trading partner of many countries in the region like Japan and South Korea, and weak demand from China could ripple through to its neighbours. South Korea’s exports to China, accounting for roughly 20% of its total, fell 25% year on year in the first eight months of this year.

And falling investment in China—especially in the real-estate sector—could weigh on commodity prices. So far prices of commodities such as iron ore have been resilient this year as demand from sectors like autos and infrastructure have softened the blows from property construction. But commodity-exporting nations such as Australia, Malaysia and Indonesia could suffer if Chinese investment remains weak.

The confidence crisis in China could also hurt companies selling to the country’s consumers. The number of Chinese tourists, in particular, is still way down from pre-Covid levels for many countries like Japan and Thailand.

As China is the economic juggernaut in the region, the country’s pain is unlikely to be its neighbors’ gain for long.

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.”
