Returns might improve, but the power of chaebols—including Samsung and Hyundai—will limit gains
3 min
South Korea is taking a page from Japan to boost its stock market. There are certainly some low-hanging fruits to pick, but the country’s large family-controlled corporate empires, known as chaebols, could be an obstacle to more meaningful structural change.
The country’s stock exchange is set to unveil a stock index that will take into account factors such as profitability and shareholder returns. That is modelled after a similar move taken in 2014 by Japan, which uses its new index to essentially name and shame companies that failed to make the grade.
The new index is just a part of Korea’s “corporate value-up” program announced in February, aiming to boost the valuations of its market with shareholder-friendly policies. The government also proposed making changes to the tax code to encourage companies to pay more dividends. More broadly, South Korea hopes to copy the success of Japan’s drive to improve corporate governance and returns to investors.
Buybacks and dividends in Japan have risen, and shareholders have grown more vocal. Companies also are unloading their nonstrategic shareholdings in other companies, slimming down their balance sheets.
As a result, Japan has been one of the best-performing markets in the world in recent years. The Topix index hit a record high in July, nearly 35 years after its famous bubble burst.
On the other hand, South Korea’s stock market has long suffered from a so-called Korea discount , as it trades more cheaply than other emerging markets. Its main benchmark, Kospi Composite index, has been valued at an average 12 times forward earnings in the past decade, compared with around 15 times for Japan’s Topix and Taiwan’s Taiex each.
Japan’s index has gained 40% since the end of 2022, while Taiwan’s has surged 57%. Korea’s, by contrast, has gone up only 16% over the same period.
Similar to their counterparts in Japan, Korean companies haven’t historically been willing to return much capital to shareholders. The dividend yield on the Kospi is below 2%, which is lower than many markets. Buybacks are paltry and, more important, many Korean companies don’t cancel the shares they have bought back, instead keeping them as treasury shares, using that as a tool for major shareholders to keep control of the company.
On that front, there seems to be some progress. Treasury share cancellation, excluding Samsung Electronics , so far this year has already more than doubled the full-year level of 2023, according to Goldman Sachs . New regulations restricting how companies can use their treasury shares is probably one reason. Financial companies, in particular, have been eager to buy back and cancel their shares.
The elephant in the room, however, is the power of chaebols, which dominate Korea’s economy and stock market. Companies in the Samsung group, for example, make up more than 20% of the Kospi index. Besides the electronics brand, this includes companies in areas as disparate as financial services and shipbuilding. The interests of the families who control these vast corporate empires don’t usually align with those of the minority shareholders.
Instead, they have long used convoluted corporate structures, including extensive cross-shareholdings, to maintain their grip on the conglomerates. Given the chaebols’ strong economic and political influence in the country, they won’t be so easily pressured as Japanese companies have been to unwind these arrangements.
High inheritance taxes are another reason the families might not necessarily want high share prices for their companies. The government has proposed reducing the tax, but it might not be enough.
Korea’ stock market, which houses some of the world’s best-known brands, including Samsung and Hyundai Motor , has long been a laggard. The government’s new push might yield some successes, but its biggest companies could remain the toughest nuts to crack.

Wall Street’s hottest momentum trade has reversed sharply, as former winners tumble and heavily shorted stocks surge.

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.”
