During the second week of July, semiconductors dominated South Korea’s stock market. Samsung Electronics (005930.KS) reported its highest-ever quarterly earnings, only to see its share price tumble, while SK Hynix (000660.SK) opened a new chapter by attracting global capital ahead of its U.S. listing. Here is a closer look behind the scenes of this “semiconductor super week,” where bullish and bearish forces collided.<\/p>\n
Not an earnings shock, but an expectations shock \u2014 record profits met with a cold market<\/p>\n
Samsung Electronics’ preliminary second-quarter 2026 results, released on July 7, exceeded market forecasts. Revenue reached 171 trillion won (approximately $113.1 billion) and operating profit hit 89.4 trillion won (approximately $59.1 billion). Revenue surged 129% year-over-year, while operating profit skyrocketed 1,810%. This marks the highest quarterly operating profit in the history of global technology companies, surpassing even Nvidia’s estimated operating profit of approximately 80.9 trillion won ($53.5 billion) for the same period. Yet Samsung’s stock closed down 6.92% that day. SK Hynix also dropped more than 6%, and the Kospi index briefly plunged over 8%, triggering South Korea’s sixth circuit breaker of the year.<\/p>\n
Why did the market turn its back on record-breaking results? Experts unanimously point to the gap between reality and expectations. “The problem isn’t the earnings themselves, but that overly inflated earnings expectations are now correcting,” said Na Jung-hwan, an analyst at NH Investment & Securities. “Semiconductor stock prices rose faster than profit growth this year, and this earnings release became a catalyst for profit-taking.” Indeed, Samsung’s stock had surged over 160% year-to-date, and the market had grown accustomed to blowout results. Park Yu-ak, a senior analyst at Kiwoom Securities, diagnosed the situation: “For the first time, market expectations and actual results converged at similar levels. Investors conditioned to constant upside surprises dumped shares in disappointment.”<\/p>\n
Concerns about the semiconductor cycle peaking also played a role. According to market research firm TrendForce, DRAM contract prices are projected to rise 13\u201318% quarter-over-quarter in the third quarter of 2026. While still climbing, the pace has decelerated sharply from the 93\u201398% surge in the previous quarter. Prices are still rising, but the mere fact that the rate of increase has slowed was interpreted as a cycle peak signal.<\/p>\n
The 10 trillion won margin debt blowback \u2014 forced liquidation fears spread<\/p>\n
Behind the sharp sell-off looms the shadow of “debt-fueled investing.” According to the Korea Financial Investment Association, margin loan balances on the Kospi stood at 29.56 trillion won (approximately $19.6 billion) as of July 6, up roughly 1.5 trillion won (approximately $992.1 million) from a month earlier. The bulk of that increase was concentrated in Samsung Electronics and SK Hynix. The combined margin balance for the two stocks reached 10.6 trillion won (approximately $7.0 billion), accounting for 36% of the Kospi’s total margin debt. Excluding these two names, margin balances across the rest of the Kospi actually fell by more than 1 trillion won.<\/p>\n
The danger is that as share prices plummet, collateral ratios could fall below critical thresholds, turning the specter of forced liquidations into reality. Typically, when the collateral ratio drops below 140%, investors must post additional margin. Failure to do so triggers forced sale of holdings at the start of the next trading session. With over 10 trillion won in leveraged positions, a cascade of forced selling could unleash a wave of sell orders.<\/p>\n
SK Hynix lands on Nasdaq \u2014 a global bet on the ‘king of AI memory’<\/p>\n
Meanwhile, SK Hynix is set to list American Depositary Receipts (ADRs) on the Nasdaq on July 10 (local time), knocking on the door of global capital markets. The offering totals 177.9 million ADRs, with 10 ADRs representing one common share. Underwriters include Wall Street heavyweights Bank of America, Citigroup, Goldman Sachs, and J.P. Morgan.<\/p>\n
Market attention is squarely focused on the fundraising scale. Initially projected at $29.4 billion (~44.5 trillion won), the figure has been adjusted down to approximately $24.5 billion (~37 trillion won) due to the recent share price correction. This reflects not a reduction in the number of ADRs offered, but a natural adjustment tied to the decline in the underlying Korean share price. Even at this level, it ranks as the second-largest equity offering in global stock market history, comparable to SpaceX’s IPO last month and the IPOs of Saudi Aramco and Alibaba.<\/p>\n
More notable is the quality and intensity of demand. According to market sources, the ADR offering was oversubscribed by more than seven times. Major global hedge funds, long-only funds, and sovereign wealth funds \u2014 including Baillie Gifford, Coatue Management, and Situational Awareness Partners \u2014 indicated buying interest of up to $7 billion (~10.6 trillion won). Individual institutional orders reportedly ranged from $200 million to over $1 billion.<\/p>\n
The reason for their enthusiasm is clear. SK Hynix commands a 58% share of the high-bandwidth memory (HBM) market (per Counterpoint Research, Q1 2026), the essential component for AI accelerators. The company effectively holds a near-monopoly on HBM supply for Nvidia’s GPUs, controlling a critical bottleneck in AI infrastructure. As AI data centers expand, HBM demand grows exponentially. In the eyes of U.S. institutional investors, SK Hynix is no longer just “a Korean memory company” \u2014 it is essential infrastructure for the AI era.<\/p>\n
How ADRs could reshape the landscape \u2014 two prices, two identities<\/p>\n
SK Hynix’s Nasdaq listing is viewed as more than a capital raise; it represents a potential inflection point that could reshape the company’s valuation paradigm. Until now, SK Hynix has been trapped within the “memory cycle” framework on South Korea’s stock market. No matter how strong its earnings, fears that “the cycle will turn next year” made it difficult for the stock to sustain a price-to-book ratio above 1x. In 2023, SK Hynix posted an operating loss of 7.73 trillion won (approximately $5.1 billion), a stark reminder of the cycle’s brutal swings.<\/p>\n
Expectations are high that the U.S. market will be different. American investors, well-versed in AI narratives, are more likely to focus on HBM’s structural growth trajectory. Taiwan’s TSMC (TSM) offers a compelling precedent: its ADRs have traded at an average premium of 16% over its Taiwan-listed shares. UBS recently suggested in a report that “SK Hynix ADRs will trade at a premium to the Korean-listed shares” and even proposed arbitrage strategies involving buying the ADR and shorting the local stock.<\/p>\n
It is worth noting, however, that this ADR issuance involves new share creation, making dilution of existing shareholder value \u2014 an increase in shares outstanding \u2014 unavoidable. Moreover, an ADR listing does not automatically guarantee a “cycle premium.” The sharp sell-off in recent days demonstrates that SK Hynix remains caught in a tug-of-war between two identities: an AI growth stock and a cyclical memory play.<\/p>\n
The unvarnished reality of the ‘super cycle’ hidden behind the earnings<\/p>\n
Samsung’s second-quarter results and SK Hynix’s ADR listing embody the two faces of the “super cycle” that South Korea’s semiconductor industry is experiencing. On one side, record profits are met with a “sell-on” rout; on the other, global capital is clamoring to buy in at a premium.<\/p>\n
Brokerages remain optimistic over the medium to long term. iM Securities raised its target prices, forecasting Samsung’s full-year operating profit at 340 trillion won (approximately $224.9 billion) and SK Hynix’s at 261 trillion won (approximately $172.6 billion). “Tight supply-demand conditions will sustain the memory boom through next year,” said Suh Seung-yeon, an analyst at DB Securities. Kim Woon-ho of IBK Securities added, “Samsung’s top-line growth will become more pronounced from the third quarter, when HBM4 volumes ramp up in earnest.”<\/p>\n
The key question is whether second-half earnings can restore market confidence. The market is already projecting Samsung’s third-quarter operating profit above 100 trillion won (approximately $66.1 billion). Samsung’s conference call scheduled for late July, along with capital expenditure announcements from major hyperscalers, will serve as critical tests. The price at which SK Hynix’s ADRs settle in the U.S. market will also be a crucial variable shaping the trajectory of South Korean semiconductor stocks.<\/p>\n
Ultimately, the market consensus is that this correction was driven not by poor earnings, but by expectations that had run too far ahead. “Volatility-amplifying supply-demand factors like leveraged ETFs will keep swings wide, but the underlying earnings growth trajectory remains intact, so share prices will eventually converge with fundamentals,” said Na Jung-hwan. In other words, the super cycle for “Semiconductor Korea” is not over yet.<\/p>\n","protected":false},"excerpt":{"rendered":"During the second week of July, semiconductors dominated South Korea’s stock market.
