Samsung Posted Its Best Quarter Ever. Kospi Shrugged and Sold Anyway.
Samsung Electronics reported the largest quarterly profit in its history on Thursday — consolidated operating profit of 89.5 trillion won (about $61.3 billion), up 1,813.8% year over year, with the Device Solutions semiconductor division alone contributing 89.2 trillion won on revenue of 127.5 trillion won, up 56% sequentially — and Kospi investors sold the stock anyway. Samsung shares rose more than 8% intraday to reclaim the 220,000-won level before giving back the entire move to close down 0.72% at 207,000 won, dragging the index from an intraday high of 5,976.82 to a 1.23% loss at 5,593.56, per the Seoul Economic Daily. SK Hynix, which reported Wednesday, fell a further 5.64% to 1.322 million won, extending Kospi's three-session slide to 17% (1,162.19 points) — a run that has now erased roughly 396 trillion won ($271 billion) of combined Samsung and SK Hynix market value, per Tech Times. Samsung's own disclosure gave the selling a reason: management offered no update on shareholder returns and left long-term supply-agreement pricing vague, even while forecasting the memory shortage would persist through 2028.
"This is merely a period in which a negative narrative surrounding semiconductors, the market leaders, is forming — such as an earnings peak-out and the end of the AI investment cycle — but fundamental damage, such as earnings estimates turning downward in earnest, has not materialized." — Han Ji-young, Analyst, Kiwoom Securities, via the Seoul Economic DailyHan's framing cuts against how Thursday's session actually broke down. Samsung's Device Solutions division posted its all-time record 89.2 trillion won in operating profit at roughly 70% margin, while the Mobile and Networks division swung to its first-ever operating loss of 0.7 trillion won (about $480 million), as the same elevated memory prices enriching the chip business now squeeze the phone business that buys from it, per Tech Times. That bifurcation, not a cyclical top, may be the more durable story: Samsung told analysts it expects to lock 60-70% of production capacity into five-year supply contracts with data-center customers and that shortages will intensify next year before persisting into 2028, per the Seoul Economic Daily — a forecast that, if it holds, argues Thursday's reversal was sentiment repricing a stock priced for perfection, not a read on the underlying memory cycle.

Record Profits, Still No Reward: Samsung and Lam Research Show the Pattern Holds
- Samsung's Device Solutions division posted an all-time record 89.2 trillion won in operating profit at roughly 70% margin, while the Mobile and Networks division swung to a first-ever operating loss of 0.7 trillion won, and the foundry business said it has secured 2-nanometer orders from major customers and is in talks with Broadcom, per Tech Times. Why it matters: the split shows how concentrated Samsung's profitability has become in memory, leaving the mobile business structurally exposed to the same pricing cycle that makes the chip division rich.
- Lam Research reported fiscal fourth-quarter revenue of $6.72 billion and EPS of $1.82, both above the $6.65 billion and $1.68 consensus, and lifted its long-term gross-margin target into the mid-50% range, per Benzinga. Why it matters: shares fell 7.04% in regular trading before rebounding 5.31% after hours, and management's comments that AI demand is lifting NAND, DRAM and advanced-foundry spending diversify the AI-capex story beyond memory into wafer-fab equipment.

Samsung Bets the Shortage Runs to 2028 — the Market Wants Proof Sooner
- Samsung told analysts on its earnings call that the memory supply shortage will intensify next year and persist into 2028, and that it has signed long-term supply agreements with more than ten customers on roughly five-year terms, per the Seoul Economic Daily. Why it matters: a multi-year supply-demand forecast from the industry's largest producer is a structurally bullish signal for DRAM and HBM pricing, but the lack of specifics on LTA pricing left investors unable to size the earnings benefit.
- Micron shares fell further even after Samsung's 1,813.8% profit surge, extending a decline that has left the stock down roughly 30% from its June peak, per Barron's. Why it matters: the divergence between record absolute memory profits and falling memory-stock prices suggests the market is pricing a peak in the earnings cycle rather than a peak in demand, a distinction that will keep pressuring the whole memory cohort until proven wrong.
Supply Chain
Trailing-Edge Foundry and Photonics Quietly Post Their Own Good News
- UMC reported Q2 2026 revenue of $2.12 billion with 85% utilization and a 32.5% gross margin, and CEO Jason Wang said Intel 12-nanometer design kits will reach customers by year-end, alongside the first mass-produced 12-inch silicon-photonics wafers, per Tech Times. Why it matters: a trailing-edge foundry posting rising utilization and a concrete Intel design-kit timeline is evidence that AI-driven demand is broadening beyond leading-edge logic and memory into mature-node and packaging capacity.
- GlobalFoundries signed a letter of intent with the U.S. Department of Commerce for a $300 million CHIPS Act award to advance next-generation silicon photonics, with Marvell welcoming the investment as a co-packaged-optics supplier, per GlobeNewswire. Why it matters: continued CHIPS Act funding for domestic advanced-packaging capacity supports GlobalFoundries' turnaround narrative and Marvell's optical-interconnect roadmap, both distinct from the memory and AI-compute names dominating headlines this week.
Policy Desk
Fed, Yields and Seoul's New Leverage Curbs Reframe the Risk Math
- The Federal Reserve held its benchmark rate at 3.50-3.75% with a hawkish tone, and the 30-year Treasury yield rose to 5.201% intraday, its highest level since 2007, per the Seoul Economic Daily. Why it matters: rising long-duration yields raise the discount rate applied to future earnings, compressing the valuation math underpinning AI-capex-driven semiconductor stocks just as Asian markets were already de-risking.
- South Korea's financial regulators will raise the minimum deposit requirement for single-stock leveraged ETFs to 30 million won from 10 million won starting July 31, per the Seoul Economic Daily. Why it matters: the rule targets the leveraged-ETF mechanism blamed for amplifying this week's back-to-back circuit breakers in Samsung and SK Hynix, two stocks that together make up roughly half of Kospi's market capitalization.
Analyst Corner
China's Memory Ambitions and a Contrarian Bull Case Get a Second Look
- SemiAnalysis (background reading, published Jun 23): "China's CXMT Is Set to Challenge DRAM Incumbents" models CXMT's DRAM pricing at only 5-10% below Samsung, SK Hynix and Micron, with global DRAM still undersupplied through 2028 even as CXMT's capacity share climbs — a framework directly relevant to Samsung's own 2028 shortage call this week.
- UBS, initiating on SK Hynix's U.S.-listed shares with a Buy rating, argued the stock's 35% pullback from its peak has changed little about the underlying HBM demand picture, per TipRanks — a bullish outlier against Thursday's continued selling.
Calendar / Week Ahead
Monolithic Power and SanDisk Put Analog and Memory Back on the Clock
- Thursday, July 30 — Monolithic Power Systems reports second-quarter 2026 results after the close. Analysts expect revenue of $903.97 million and EPS of $5.88, per StockTitan, the next read on analog and power-management demand outside the memory and AI-compute names.
- Wednesday, August 5 — SanDisk reports fiscal fourth-quarter results. Shares have fallen more than 50% from their peak on concerns over China's expanding memory capacity, per TradingKey, making it the week's clearest test of whether NAND pricing power is holding up.
