Samsung's 8% Rebound Conceals a Battle Between AI Pricing Power and Market Nerves

Seoul's KOSPI rebounds 5.76% after a 9% plunge triggered by Meta cloud doubts, as Samsung and SK Hynix surge. Regulator eyes leveraged ETFs as amplifier.

Seoul's benchmark KOSPI index was forced into a temporary trading halt on Thursday as a wave of panic selling swept through Samsung Electronics and its memory-chip peers. By Friday, the script had flipped entirely: Samsung surged 8.22% to close at 309,500 won, while rival SK Hynix jumped 10.88%. The index itself rebounded 5.76% to 8,088.33 points, powered by a mix of short-covering and bargain hunters.

The violent two-day swing has drawn the attention of Korea's financial regulator, which publicly cited heavily leveraged single-stock ETFs as amplifying the selloff beyond what fundamentals justified. The incident reignites debate over whether such products need tighter oversight, especially given Samsung's outsized weighting in the KOSPI — the index has nearly doubled this year, driven almost entirely by AI memory speculation.

The immediate trigger for Thursday's 9% weekly plunge came from a report on Meta's cloud strategy that sparked industry-wide doubts about the sustainability of AI infrastructure spending. Analysts at NH Investment & Securities and other local houses have since dismissed the reaction as overblown, arguing that demand for high-performance DRAM remains solid. The selloff also dragged down U.S. memory stocks: Micron closed Thursday's shortened session 5.5% lower at $975.56, though it remains up 166.4% year-to-date. Many market watchers see Seoul's rapid recovery as a positive signal for how U.S. chip names might trade when exchanges reopen after the Independence Day holiday.

Despite the Friday bounce, Samsung stock sits 17% below its 52-week high of 374,500 won, hit on June 19. Over the trailing 30 days, it is still down roughly 12%. On a 12-month basis, however, the shares have nearly quadrupled — gaining about 390% — thanks to the chip super-cycle that kicked off long before the current correction.

Pre-earnings analyst estimates are divided. Korea Investment & Securities trimmed its second-quarter operating profit forecast by 10% to 8.6 trillion won, citing one-off employee bonuses of around 1.8 trillion won. Yet the same house raised its price target to 590,000 won, citing an expected recovery in Samsung's competitiveness on high-bandwidth memory (HBM) chips. Citi followed with an upgrade to 530,000 won, underpinned by robust server-DRAM pricing tied to AI processors. Morningstar lifted its fair-value estimate to 330,000 won, describing Samsung's pricing power in memory as "unprecedented."

That pricing power is already reshaping the entire supply chain. Samsung and SK Hynix are pressing substrate suppliers for cost cuts while simultaneously raising DRAM chip prices by up to 20% for customers such as notebook and smartphone makers. The pass-through to consumers is visible: Apple has raised MacBook and iPad prices, explicitly blaming higher memory costs. Samsung's average DRAM selling price rose 42% in the second quarter, while NAND prices surged 93%. Capacity constraints are driving the trend as the industry shifts production toward next-generation HBM4 and advanced NAND processes.

Micron CEO Sanjay Mehrotra provides a cautionary counterpoint: during the 2023 memory downturn, customers slashed prices by two-thirds, starving the industry of investment capacity. That under-investment is now the root cause of today's shortages, he argues, raising the question of how long the current pricing boom can last before demand buckles.

On the technology front, Samsung's progress with HBM4E — the seventh generation of high-bandwidth memory — appears encouraging. Yield rates for the latest iteration are reportedly above 70%, a threshold that signals near-commercial readiness. The company is also in talks with AI startup Anthropic to manufacture custom chips using its 2-nanometer process and advanced packaging technology. A deal would cement Samsung's role as a strategic infrastructure partner for one of the leading players in generative AI.

Two key dates loom for investors. On July 7, Samsung will release preliminary second-quarter results, which will offer the first concrete gauge of how the memory price surge has translated into profit. Later in the month, earnings from major U.S. technology companies will provide further clues on global AI infrastructure spending — the force that ultimately determines whether Samsung's pricing strategy remains credible or begins to crack.
