SK Hynix priced its U.S. offering at $149 per ADR before the shares began trading on a when-issued basis on July 10.<\/p>\n
The stock opened at $170, roughly 14% above its offering price, reached $177, and finished its first session at $168.01.<\/p>\n
However, by midday on July 13, SK Hynix shares fell around 9%, hitting a low of $151.30 and giving back most of its opening-day jump.<\/p>\n
And the day ended with SK Hynix closing at $139.14.<\/p>\n
More AI:<\/strong><\/p>\n That contrast from a strong debut to a sharp pullback the next trading day captures the debate surrounding SK Hynix.<\/p>\n Investors are gaining easier access to a major supplier of the memory chips required for AI.\u00a0<\/p>\n But they are also buying into an industry known for expensive factories, rapid changes in supply and demand, and dramatic swings in memory-chip prices.<\/p>\n All of which has a dynamic effect on stock prices, and investors are aware of it.\u00a0<\/p>\n Look at SpaceX, down 14% this past month, and at $137 on Monday, July 13, it has edged closer to its $135 IPO price.<\/p>\n Meanwhile, the selling was even more severe in South Korea.<\/p>\n SK Hynix\u2019s Seoul-listed shares fell more than 15% on July 13 as investors locked in profits following a huge AI-driven rally.\u00a0<\/p>\n The selloff pulled South Korea\u2019s Kospi index down about 9% and triggered a temporary marketwide trading halt, Reuters reported.<\/p>\n TheStreet Pro\u2019s Alex Frew McMillan notes that the listing comes at a \u201ctumultuous\u201d time, \u201cwith the bull run in semiconductor stocks looking decidedly toppy, creating very choppy trade.\u201d<\/p>\n \u201cAny hint of a sale or profit slowdown is punished severely after a record first six months of the year,\u201d said McMillan.<\/p>\n Bloomberg / Getty Images<\/p>\n<\/figcaption><\/figure>\n Despite the Monday sell-off, SK Hynix sold 177.9 million ADRs at $149 each, raising about $26.5 billion.<\/p>\n Ten ADRs represent one SK Hynix ordinary share.\u00a0<\/p>\n The transaction therefore represented the equivalent of 17.79 million newly issued shares, or about 2.44% of the company\u2019s shares outstanding following the offering.<\/p>\n Demand was more than seven times the number of shares available, reflecting strong investor interest in a company at the center of the AI memory supply chain.<\/p>\n The deal surpassed Alibaba\u2019s $25 billion 2014 offering as the largest U.S. stock sale by a company based outside the United States, according to TheStreet Pro.<\/p>\n SK Hynix began trading on July 10 under the temporary ticker SKHYV on a when-issued basis.<\/p>\n The ticker changed to SKHY when regular-way trading began on July 13, with settlement scheduled for July 14.<\/p>\n Although the transaction is being described as an IPO, SK Hynix did not become a publicly traded company for the first time.<\/p>\n The business was founded as Hyundai Electronics in 1983 and began its initial public offering process in South Korea in 1996.\u00a0<\/p>\n It joined SK Group and adopted the SK Hynix name in 2012.<\/p>\n Its ordinary shares have traded on the Seoul exchange for decades.<\/p>\n The 2026 transaction is a U.S. offering of sponsored ADRs intended to raise money for additional factories and equipment.<\/p>\n Before the Nasdaq listing, U.S. investors could access unsponsored SK Hynix ADRs over the counter under the ticker HXSCL.<\/p>\n But trading volume was limited, and the company was not directly involved in that program.<\/p>\n The new sponsored listing should provide stronger trading liquidity and better price discovery, according to McMillan.<\/p>\n The strong demand did not eliminate concerns that investors might rush to take profits after the shares began trading.<\/p>\n TheStreet Pro\u2019s James \u201cRev Shark\u201d DePorre questioned before the debut whether SK Hynix could experience the same \u201csell-the-news\u201d pressure that followed SpaceX\u2019s listing.<\/p>\n DePorre noted that SK Hynix\u2019s deal was driven more heavily by institutional investors.\u00a0<\/p>\n Baillie Gifford, Coatue Management, and Situational Awareness Partners took roughly one-quarter of the offering.<\/p>\n That investor mix could mean fewer traders quickly flipping their allocations, though DePorre said selling pressure could still emerge after initial demand fades.<\/p>\n The decline arrived sooner than that thesis suggested.<\/p>\n SK Hynix\u2019s U.S. shares fell nearly 9% on their first day of regular trading, while the company\u2019s South Korean shares suffered an even larger loss.<\/p>\n McMillan had also warned investors to expect \u201cintense volatility\u201d because semiconductor trading had become highly leveraged and memory-chip stocks had already posted enormous gains.<\/p>\n SK Hynix\u2019s Seoul shares had risen almost 359% from the beginning of 2026 through their June 25 record before retreating nearly 27% from that high by July 9.<\/p>\n TheStreet Pro analyst also highlighted customer concentration and the possibility that major technology companies could eventually slow spending on AI data centers.<\/p>\n SK Hynix\u2019s business may sound far removed from the average shopper, but memory chips affect the price and performance of many products consumers use daily.<\/p>\n DRAM provides the short-term working memory that allows computers, phones, and other devices to run applications and access information quickly.<\/p>\n NAND flash stores data after a device is turned off and is used in smartphones, tablets, solid-state drives, and other electronics.<\/p>\n SK Hynix also manufactures complementary metal-oxide semiconductor image sensors, or CIS products.<\/p>\n Those sensors can be used in smartphones, laptops, medical devices, digital cameras, vehicles, security systems, gaming consoles, and home appliances.<\/p>\n The company\u2019s HBM products are more directly tied to data centers, but the consequences of the AI spending boom can spread throughout the electronics industry.<\/p>\n AI companies and cloud providers have been buying large quantities of advanced memory, tightening supply and driving up prices.<\/p>\n McMillan noted that elevated chip costs were already moving through the production chain and contributing to higher prices for products such as Microsoft\u2019s Xbox Series X and Sony\u2019s PlayStation 5 at a point in their life cycles when consoles would typically be discounted.<\/p>\n For consumers, SK Hynix\u2019s expansion could eventually help ease memory shortages by adding new production.<\/p>\n But those factories take years and billions of dollars to complete.\u00a0<\/p>\n In the meantime, strong demand for AI infrastructure can keep memory prices elevated, potentially increasing costs for PCs, smartphones, gaming systems, and other devices.<\/p>\n SK Hynix has also become one of the biggest winners from the rapid expansion of AI data centers.<\/p>\n The company held about 58% of the global HBM market by revenue\u00a0 and 29% of DRAM share during the first quarter of 2026, according to Counterpoint Research.<\/p>\n The bullish case is that spending on AI servers will continue to grow, keeping demand for HBM and advanced DRAM ahead of available supply.<\/p>\n The stock\u2019s opening-day surge showed how eager investors were to make that bet.<\/p>\n But its sharp decline the next day also shows how quickly they can reconsider it.<\/p>\n Related: Bessent’s Treasury has troubling news for every taxpayer<\/strong><\/p>\n #Major #chip #stock #plunges
