On April 10, 2026, the Korean stock market was abuzz with questions about the future of HS Hyosung, a company that, just two years after its high-profile spin-off from Hyosung, finds itself mired in a prolonged stock slump and mounting investor frustration. While its parent company, Hyosung, has soared to new valuation heights, HS Hyosung’s fortunes have taken a decidedly different turn—leaving shareholders and market watchers alike searching for answers.
According to the Korea Exchange, HS Hyosung closed at 53,900 KRW on April 9, 2026. That’s a staggering 35% drop from its price on July 29, 2024, the day it was re-listed after its split from Hyosung. In stark contrast, Hyosung’s own shares have skyrocketed, climbing 196% over the same period to reach 149,600 KRW. The divergence is dramatic, and the numbers tell a clear story of two companies on very different trajectories.
Trading activity underscores the market’s waning enthusiasm for HS Hyosung. The company’s average daily trading volume in 2026 has fallen to 27,000 shares, down 25% from its first year back on the exchange. Institutional investors, once a crucial pillar of support, have steadily offloaded their positions, with net sales totaling 277,647 shares since the re-listing. The message from the market seems blunt: confidence is ebbing away.
What’s behind this growing gap? The answer lies in the companies’ business portfolios. After the split in 2024, Hyosung retained a diverse set of subsidiaries, including Hyosung Heavy Industries, Hyosung TNC, Hyosung Chemical, and Hyosung ITX. This diversification has paid off handsomely. Even as Hyosung Chemical has struggled, the robust earnings from Hyosung Heavy Industries and Hyosung TNC—whose combined operating profit last year approached 1 trillion KRW—have more than offset the group’s weaker segments. The surge in demand for power equipment, driven by the global artificial intelligence boom, has further fueled Hyosung Heavy Industries’ ascent and attracted a wave of investor interest.
HS Hyosung, by contrast, has staked much of its fate on HS Hyosung Advanced Materials, its only other listed subsidiary. This concentrated bet has exposed the company to the full brunt of global demand slowdowns and a sluggish materials market. In 2025, HS Hyosung Advanced Materials saw its operating profit plunge 28% to 157.4 billion KRW. The company’s attempt to pivot by selling its tire steel cord division to fund new ventures ultimately fizzled when the sale was called off, leaving its financing plans in limbo.
Despite these setbacks, HS Hyosung has laid out an ambitious roadmap for the future. The company has announced plans to invest 1.5 trillion KRW in anode materials by 2030, a move that could transform its business if it can secure the necessary funding. Investors, however, remain cautious, watching closely for concrete signals of a turnaround in its existing operations before buying in. The carbon fiber business, a high-multiple new materials sector, is seen as a potential bright spot. Encouragingly, carbon fiber prices have been on the rise in 2026, offering a glimmer of hope for the company’s next chapter.
Choi Young-kwang, an analyst at NH Investment & Securities, offered a tempered outlook: "Carbon fiber prices are rebounding from their lows. There are short-term headwinds in tire cord demand, but the mid- to long-term recovery in carbon fiber is more important." His remarks capture the cautious optimism that some observers still hold for HS Hyosung’s future, even as near-term results may disappoint.
Amidst this corporate soul-searching, the actions of HS Hyosung’s Vice Chairman, Cho Hyun-sang, have drawn intense scrutiny—and not just from financial analysts. Marking 650 days since he took the helm as an independent leader, Cho has made headlines for his personal investment choices. In early April 2026, he purchased a total of 1,200 shares of Hyosung Heavy Industries on the open market, spending nearly 2.99 billion KRW at approximately 2.5 million KRW per share. This move raised eyebrows for several reasons.
Back in May 2024, Cho had sold about 120,000 shares of Hyosung Heavy Industries at 339,990 KRW per share, a transaction worth 41.1 billion KRW, to comply with regulations requiring less than 3% ownership in the wake of the spin-off. Now, just two years later, he’s buying back shares at more than seven times the price he sold them for. His stake is now down to 0.66%, well below the regulatory threshold, but the timing and target of his investment have sparked controversy.
Why, critics ask, is Cho using his own funds to buy shares in his brother’s company—Hyosung Heavy Industries, led by Chairman Cho Hyun-joon—instead of supporting HS Hyosung’s sagging stock? In an era when government policy and investor sentiment both favor management-led share buybacks as a tool to boost corporate value, Cho’s decision has been met with skepticism. According to industry experts quoted by Yonhap Infomax, "The owner has invested his own money in another company, not his own, even though HS Hyosung’s stock hasn’t performed since the split. It may appear irresponsible to HS Hyosung shareholders."
The optics are further complicated by recent events at other Korean conglomerates. The scale of Cho’s 2.99 billion KRW investment mirrors a recent 3 billion KRW self-stock purchase by Hanwha Solutions’ CEO Kim Dong-kwan, which was intended to soothe investor discontent after a surprise capital increase. In that context, Cho’s move stands out not only for its size, but for its direction—toward a sibling’s company, rather than his own.
HS Hyosung, meanwhile, is still navigating the complexities of its business separation from Hyosung Group. The two entities have already undertaken business swaps between the U.S. and Vietnam to sharpen their operational independence, but the final step will be a full adjustment of cross-shareholdings. Industry observers speculate that Cho’s recent purchases of Hyosung Heavy Industries shares could be a strategic play, aimed at boosting his leverage in any future negotiations over block deals or share swaps related to the spin-off. As one industry insider told Yonhap Infomax, "Whether securing a stake in Hyosung Heavy Industries is a strategic choice to enhance the completion of the spin-off, or ends up hindering HS Hyosung’s growth, will have to be proven by future performance."
The stakes are high. The last piece of the puzzle is the fate of Cho’s roughly 14% stake in Hyosung itself—a holding that will need to be resolved for a clean break. For now, the market is left to watch and wait, weighing the risks and rewards of a company caught between old allegiances and a new, uncertain future.
As HS Hyosung faces these challenges, investors are looking for clear signals—either a convincing turnaround in its core businesses or a bold strategic move to chart a new course. Until then, the company’s fortunes remain, as one observer put it, "more uncertain than ever."
