When the market "prices in perfection," even Samsung's outstanding performance is not good enough.

Samsung Electronics delivered a historic quarterly profit surge of 19 times, only to see its stock price plunge sharply in a single day. This is not because the earnings were insufficient, but because the market had already priced in "perfection" in advance—when the financial results were released, it merely served as a signal for capital to exit.

On July 7, an article from Wall Street Insights stated that Samsung Electronics' second-quarter operating profit surged approximately 19 times year-on-year to 89.4 trillion Korean won (approximately $58.4 billion), not only setting a quarterly historical record but also surpassing Nvidia's operating profit of $894k in the previous quarter, making it the company with the highest quarterly operating profit globally. Revenue doubled to 171 trillion Korean won, both exceeding analysts' average expectations. However, after the earnings release, Samsung's stock price fell by up to 8% in a single day, while South Korea's KOSPI index dropped 6%, and SK Hynix fell over 7%.

Wall Street Insights also mentioned in another article that the logic of "buy the rumor, sell the news" played out clearly once again. On the night before the earnings release, the Philadelphia Semiconductor Index rose 2.2% in a single day, the S&P 500 gained 0.7%, and the Nasdaq 100 rose 1.3%. As the positive news materialized, capital quickly withdrew.

Brian Cho, portfolio manager at Causeway Capital Management, bluntly stated that what the market really wants to see is whether the improvement in free cash flow can form a sustainable step change, and how management treats shareholder returns—the pricing logic has shifted from "how fast profit growth is" to "whether these profits can be turned into real cash distributed to shareholders."

In addition, the sharp reversal in market sentiment has its macroeconomic backdrop. Last week, Meta first hinted at curbing capital expenditures, triggering the largest two-day sell-off in high-beta momentum stocks since the COVID-19 pandemic. Samsung's decline also pressured similar chip stocks like SK Hynix and Micron, and the high valuation logic of the entire memory chip sector is facing a systematic reassessment.

Strong earnings, but not good enough

The Wall Street Insights article noted that Samsung's second-quarter operating profit is expected to reach 89.4 trillion Korean won, up 56% quarter-on-quarter, compared to analysts' average forecast of 84.2 trillion Korean won; revenue of 171 trillion Korean won exceeded the market estimate of 169.2 trillion Korean won, up about 129% year-on-year. The company plans to release its full financial report on July 30, which will disclose net profit and segment data for each business division.

The core driver of this growth lies in the continued tight supply of memory chips. The strong demand for high-bandwidth memory (HBM) from AI data centers has prompted manufacturers to shift production capacity toward high-end products, leading to insufficient supply of traditional DRAM and NAND memory chips and driving up prices across the board.

According to HSBC data, the average selling price of DRAM rose over 40% quarter-on-quarter in the second quarter, while NAND prices increased over 50%. Citigroup Research data is similar, showing that average DRAM and NAND prices rose 44% and 53% quarter-on-quarter, respectively.

However, although revenue of 171 trillion Korean won exceeded analysts' average expectations, it fell short of some institutions' optimistic forecast of 173.9 trillion Korean won. Against the backdrop of valuations already pushed to high levels, this small gap was enough to trigger profit-taking.

The highlight of the memory business obscured several cracks in the company's overall structure. Analysts expect that Samsung's foundry and logic chip (LSI) business losses may widen further this quarter, partly because bonus expenses are proportionally allocated to the overall cost of the semiconductor division.

In May this year, Samsung reached a compensation agreement with its chip division employees, linking performance bonuses to operating profit and stipulating that, upon meeting specific profitability targets, 10.5% of the semiconductor division's annual operating profit would be set aside for special bonuses. Some analysts pointed out that if this provision had not been made, Samsung's operating profit would have exceeded market expectations even further.

AI demand supports memory boom, but marginal signals weaken

The core logic driving this memory chip supercycle remains intact: the massive expansion of global AI data centers has generated strong demand for high-end memory chips, and memory shortages have become a key bottleneck for AI development.

Multiple industry executives, including Nvidia CEO Jensen Huang and OpenAI COO Brad Lightcap, have issued warnings about this. Major manufacturers are prioritizing the supply of high-end memory products, leading to simultaneous shortages of traditional memory products. Analysts expect the supply shortage to last at least until 2027.

Market research firm Counterpoint predicts that the average operating profit margin of the three major memory manufacturers—Samsung, SK Hynix, and Micron—will remain between 75% and 80% in the second quarter of this year. The firm noted in its report that some views consider such high profit margins as "excessive profiteering" and warned that "if this situation continues, memory manufacturers may face regulatory pressure."

Additionally, the Wall Street Insights article mentioned that more noteworthy than the earnings themselves are signals from the upstream part of the industry chain. Meta recently hinted at capping AI capital expenditures, which the market interpreted as an early warning that technology giants' AI infrastructure investments may have peaked, directly triggering one of the most severe two-day sell-offs in high-beta momentum stocks since the COVID-19 pandemic.

Jean Boivin's team at BlackRock Investment Institute put it more directly: The core of the AI bubble debate is not current valuations, but whether future earnings can remain at extraordinary levels. If AI cannot translate its current scarcity into real productivity improvements, the extremely high earnings expectations will face revision.

Samsung underperforms SK Hynix; South Korea bets on AI chip dominance

From a national strategic perspective, the South Korean government views Samsung and SK Hynix as core pillars in competing for global AI leadership. The Samsung Group and SK Group each plan to build two chip factories in southwestern South Korea, with a combined investment of 800 trillion Korean won to rapidly expand production capacity. South Korea aims to double its memory chip production capacity within five years, and Samsung has announced it will invest over $70 billion in capacity expansion and R&D by 2026.

In terms of stock performance, Samsung's cumulative gain this year is about 165%, but it clearly underperforms its competitor SK Hynix's gain of about 260%. The gap mainly stems from differences in product structure—SK Hynix's business is highly concentrated on high-end memory chips for AI computing needs, while Samsung's product portfolio is more diversified, spanning both chips and consumer electronics. This divergence sends a clear signal: in the current race, focus is more favored by capital than scale.

Samsung's full financial report will be released at the end of this month, and the breakdown data for each business unit will tell the market how much real value this round of AI capital spending has actually converted. That number will become an important reference point for the next phase of AI hardware investment logic.
