On July 7, 2026, the Korea Composite Stock Price Index (KOSPI) opened sharply lower, with an intraday drop of over 4%. Heavyweight stock Samsung Electronics led the decline, with its intraday loss widening to 7.5% at one point. As of writing, Samsung Electronics' decline remains above 7%.
The trigger for the sell-off was precisely an explosive earnings guidance.
Samsung Electronics' preliminary second-quarter financial results released on the same day showed consolidated revenue of 171 trillion won (approximately $1.118 billion), up 129.3% year-on-year; operating profit reached 89.4 trillion won (approximately $58.4 billion), up 1,810.2% year-on-year. This figure not only far exceeded the analysts' average estimate of 84.2 trillion won, but the single-quarter profit alone surpassed the total profit for the three years from 2023 to 2025. Samsung has set a new single-quarter profit record for three consecutive quarters.
With record-high earnings, the stock price suffered a heavy blow. What logic lies behind this seemingly contradictory market reaction?
Market Expectations Already Outpaced Earnings: Good News Priced In Is Bad News?
Samsung Electronics' earnings were not "below expectations," but rather market expectations had already run ahead of the results.
Before the earnings release, Wall Street's consensus estimate for Samsung's second-quarter operating profit was around 86 trillion won, and some brokerages even forecasted as high as 90 trillion to 100 trillion won. When the actual figure of 89.4 trillion won landed, it exceeded the average estimate of 84.2 trillion won but failed to meet the upper limit set by optimistic analysts.
More critically, the 89.4 trillion won operating profit already includes approximately 20 trillion won in provisions for semiconductor employee performance bonuses. In May this year, Samsung reached a compensation agreement with its chip division employees, linking performance bonuses to operating profit, stipulating that under specific profitability targets, 10.5% of the semiconductor division's annual operating profit would be set aside for special bonuses. Analysts pointed out that if this bonus provision were excluded, Samsung's actual operating profit could have easily exceeded 100 trillion won.
This means that the market had already fully priced in the highest earnings expectations. When the actual data failed to exceed the most optimistic scenario, selling triggered by "good news priced in" followed. Statistics show that in the past eight preliminary earnings releases, Samsung's stock price fell on the release day or the following day on four occasions.
Memory Business Surges, But Foundry and Logic Chips Continue to Bleed?
The core driver of Samsung Electronics' earnings explosion came from the Device Solutions (DS) semiconductor division. Increased demand for AI servers has pushed up prices for high-bandwidth memory (HBM) and DRAM, with the DS division's single-quarter operating profit estimated at around 80 trillion won.
However, beneath the shine of the memory business, structural concerns within Samsung are mounting.
Analysts predict that the losses from the company's foundry and logic chip (LSI) businesses may widen further this quarter. Part of this loss stems from bonus expenses being proportionally allocated to the overall cost of the semiconductor division. But the deeper issue is that Samsung has not narrowed the gap with TSMC in advanced process foundry, and the logic chip business has long failed to achieve stable profitability.
This "fire and ice" business structure makes Samsung's overall profitability highly dependent on the cyclical boom of memory chips. Once the memory cycle turns, losses from foundry and logic chips will further drag down group profits.
How Long Can the Memory Chip Super Cycle Last? The Battle Between Pricing Power and Cycle Peak
The fundamental driver of this profit surge is that the global AI infrastructure buildout has fully spread from HBM to traditional DRAM and NAND flash memory.
As manufacturers prioritize capacity for higher-margin AI server products, conventional memory chips for smartphones and PCs are facing historic supply tightness. Citi Research data shows that average DRAM selling prices rose 44% quarter-on-quarter in Q2, while NAND flash average prices increased even more, by 53%. HSBC's calculations also corroborate this trend, recording price jumps of over 40% and over 50%, respectively.
Analysts generally expect the supply-demand imbalance for memory chips to persist at least until 2027, allowing companies like Samsung to continue enjoying strong pricing power. To secure capacity, downstream customers are increasingly seeking long-term supply agreements, further solidifying expectations of high prices.
But the market is also concerned about another direction: has the memory chip price increase cycle already peaked? Some analysts point out that despite the current severe shortage, expansion plans by major manufacturers are accelerating. SK Hynix plans to list in the US this week at a scale of $29 billion, with one of the uses of proceeds being capacity expansion. Once supply collectively increases, memory chip prices could face reversal risks.
External Catalysts Strike Consecutively, Semiconductor Sector Sentiment Turns Weak Ahead of Fundamentals
Samsung Electronics' recent stock price volatility did not start on July 7. Over the past month, the stock has seen extreme movements of over 7% on eight trading days.
On June 23, Samsung Electronics fell 12.31%, its biggest single-day drop since 2008, triggered by profit-taking in semiconductors due to US interest rate concerns. On July 2, the stock plunged again by 9.06% on a report that Meta was preparing to launch a cloud business called "Meta Compute," selling excess computing resources from its data centers to external customers. This news raised concerns about semiconductor supply adequacy—Meta was shifting from an investor in AI data center expansion to a cloud capacity supplier.
From the intraday high of 374,500 won on June 19 to the low of 281,500 won on July 2, Samsung Electronics fell 25% in two weeks. Morgan Stanley's chief equity strategist noted that recent momentum in the semiconductor sector has clearly waned, with the Philadelphia Semiconductor Index down nearly 12% from its high.
Samsung Electronics and SK Hynix together account for 55.99% of the KOSPI index. Volatility in these two semiconductor giants has been significantly amplified into broader market turmoil.
Will History Repeat? Path Projection After the Leader Stock Adjustment
"Strong earnings, falling stock price" is not new for Samsung Electronics.
In a previous quarter when operating profit first exceeded 20 trillion won, Samsung's stock price also fell on the earnings release day. The only exception was Q1 2026, when operating profit of 57.2 trillion won significantly exceeded market consensus, leading to stock price gains on both the release day and the following day.
Researchers at Samsung Securities noted that recent volatility in semiconductor stocks reflects the market's different interpretations of the same phenomenon shaking investor sentiment, rather than new negative factors. Historically, after a 10% to 20% correction, leader stocks tend to resume their upward trend based on continued earnings growth.
In its latest report, Goldman Sachs stated that the recent turmoil in the South Korean stock market has not changed its bullish outlook, predicting that the benchmark KOSPI index will reach 12,000 points over the next 12 months. Goldman Sachs expects profits of South Korean listed companies to grow 320% this year, with an additional 35% growth in 2027.
However, this upward path may be "twisty and winding." Samsung Electronics plans to release its official financial report on July 30, which will disclose detailed operational specifics for each business division. The market will focus on the progress of HBM3E certification and the penetration rate of the Blackwell platform—these are the key variables determining whether Samsung can continue to benefit from the memory super cycle.
FAQ
Q: What exactly was Samsung Electronics' Q2 operating profit? Did it really exceed the total for the previous three years?
According to Samsung Electronics' second-quarter preliminary earnings guidance released on July 7, 2026, operating profit was initially estimated at 89.4 trillion won (approximately $58.4 billion), up 1,810.2% year-on-year. This figure indeed surpasses the company's total profit for the three years from 2023 to 2025.
Q: With such good earnings, why did Samsung Electronics' stock price plunge?
The core reason is that "expectations were already priced into the stock price." Before the earnings release, the market's expectations for Samsung's operating profit had been pushed to a high range of 90 trillion to 100 trillion won. Additionally, the 89.4 trillion won already includes approximately 20 trillion won in employee bonus provisions; excluding these, actual profit would have been even higher. When the actual data failed to surpass the most optimistic expectations, selling triggered by "good news priced in" occurred.
Q: How long can the memory chip price increase cycle last?
Analysts generally expect the supply-demand imbalance for memory chips to persist at least until 2027. However, the market is also watching the potential supply impact from expansion plans by major manufacturers and whether the price increase cycle is nearing its peak.
