Before the July 30 open, Samsung Electronics reported the strongest quarter in its history: KRW 171.5 trillion of revenue, up 28% from the previous quarter; KRW 89.49 trillion of operating profit, up 1,813.8% year on year and 56% sequentially; a 52.2% operating margin. All three were records. The memory business set simultaneous highs for quarterly revenue and operating profit.
The shares reached KRW 226,000 after the open, 8.39% above the previous close. They finished at KRW 207,000, down 0.72%.
KOSPI traced the same shape. It touched 5,976.82, up 5.54% from the prior close, and settled at 5,593.56, down 1.23%. SK Hynix reached a high of up 4.14% and closed down 5.64%. Two heavyweight stocks and the index itself: the intraday high was erased in all three.
Yesterday’s note ended on a question. If another record print still failed to attract buyers once Samsung’s numbers arrived, peak-cycle doubt would deepen. The answer came today. The buyers showed up and lasted half a session.
The Chairman Bought For The First Time. The Price Still Did Not Hold
The market was not indifferent to the report. That 8.39% was real, and the gap between Samsung’s −0.72% and Hynix’s −5.64% is nearly five percentage points on the same day, in the same country, along the same supply chain.
The easiest explanation is shareholder returns, and it does not survive contact with the day. Neither company gave a specific arrangement. Samsung’s CFO Park Soon-cheol said the next return policy, including a possible special dividend, was under in-depth discussion and would be shared with shareholders as soon as possible. Hynix’s call a day earlier likewise said only that additional return formats were under study. The five-point gap does not sit here.
Something else did happen on the Hynix side. On July 30, SK Group chairman Chey Tae-won bought 3,620 SK Hynix common shares on the open market, about KRW 4.79 billion at the day’s closing price of KRW 1,322,000. It was the first time he has held Hynix shares in his own name, having previously held them indirectly through SK Square, the largest shareholder. Korean outlets Newspim and Financial News reported the move as a gesture toward “responsible management.”
Hynix still closed down 5.64%, the worst of Samsung, KOSPI and Hynix. The chairman put his own money in for the first time and it did not hold the day’s price. The stock has fallen from its June 22 record closing high of KRW 2.919 million to today’s close of KRW 1.322 million, about 54.7% erased in a little over a month (measured close to close).
A record quarter and a chairman’s first purchase. Everything observable at the company level that day sat on the bullish side, and the price still went down. That weakens the reading of a fundamental repricing as the day’s main driver and pushes weight toward explanation A below. So the market did pay for the earnings. It just did not pay enough to offset the selling.
The size of that selling shows up in volume. Over three sessions KOSPI fell from 6,755.75 to 5,593.56, a 17.20% decline, with daily losses decaying from −10.84% to −5.98% to −1.23%. Turnover ran from KRW 24.29 trillion on July 27 to KRW 49.22 trillion on July 29 and back to about KRW 38.3 trillion today, still far above pre-selloff levels. Index structure makes it more visible: on exchange market-value data, Samsung’s common shares at KRW 1,210 trillion plus Hynix’s KRW 966 trillion is about KRW 2,176 trillion, roughly 47% of KOSPI’s KRW 4,611 trillion total. Add Samsung’s preferred shares (005935) at KRW 121.16 trillion and the share rises to about 49.8%, close to half.
The Deepest Hole Moved
Across these three sessions, the worst-hit patch has kept relocating.
On July 28 Korea broke alone while the US market barely moved at the index level and the split ran between semiconductors and everything else: the S&P 500 rose 0.21% and the Dow Jones Industrial Average 1.03%, the Nasdaq Composite was near flat at −0.22%, and SMH fell 3.45%. Overnight on July 29 Wall Street caught down across the board: SPY −1.54%, QQQ −2.04%, SMH −4.79%, Micron −9.94%, Nvidia −3.55%. VIX rose 13.45% to 20.66, the Dow Jones Industrial Average fell 2.19%, and TLT lost 1.65%, meaning long-end prices down and yields up.
On July 30 Korea’s decline narrowed to 1.23% and the deepest hole moved to mainland China: the semiconductor sector fell 6.28% and memory chips 5.19% (free-float market-value weighted, not exchange-published indices), ChiNext lost 3.97%, the Shenzhen Component 2.73%, Naura 5.43% and SMIC 6.04%. The Shanghai Composite fell only 0.62% and CSI 300 lost 1.10%. The same day, Taiwan’s benchmark fell 0.26%, TSMC rose 0.23%, the Hang Seng Index 0.20% and Kioxia 2.92%.
What fell was not “Asia.” It was memory plus heavy capital spending. Assets outside that line either dipped slightly or closed higher. ChangXin Memory finished at −0.15%, essentially flat, with only 6.7% of its shares freely traded and correspondingly little participation in collective repricing.
The Company Says Tighter. The Market Prices Glut
The company and the market are telling two different stories.
On the call, Samsung said that given the demand it is currently receiving from customers, the supply shortage in 2027 will be more severe than this year and will persist into 2028. At the same time the company spent KRW 16.8 trillion of capex in the second quarter, KRW 5.5 trillion more than the previous quarter, of which KRW 15.4 trillion went to semiconductors and KRW 0.7 trillion to displays, with Pyeongtaek and Taylor ramping. Hynix plans to lift 2026 capital spending by roughly 50%, to at least KRW 45 trillion, about USD 31 billion, according to Bloomberg.
The market is pricing a different script: both companies flooring the accelerator, and 2027 capacity landing on margins.
Only one of these can be right. Either the order book the companies see is accurate, the shortage runs into 2027, and current expansion is catching up rather than creating a glut; or the market is right, and capacity signed today competes with itself two years out. Call guidance is a forward-looking company view, not an established fact. Market pricing is not a fact either, only the odds currently on offer.
Not Callable Yet
Three explanations sit on the table, and I am not picking one.
A · Position liquidation. Declines sorted by crowding and AI-hardware content, largely detached from the day’s headlines. The shape supports it. The erased intraday rebound looked the same at stock, heavyweight and index level, while TSMC, the Hang Seng and the Shanghai Composite, none of them memory-heavy, held up or rose.
B · Rate repricing. The Federal Reserve held the federal funds rate at 3.50%–3.75% on July 29 for a fifth consecutive meeting, but on a 9-3 vote, with three members (Hammack, Kashkari, Logan) favouring a 25 basis point increase. The statement described solid economic expansion and strong capital investment. Long-end yields rose that day, the 10-year by 6bp and the 30-year by 11bp to 5.20%, on Treasury CMT data. Long-duration, capital-hungry assets get compressed by the discount rate. The Dow lost 2.19% that day, so it was not only technology getting hit, and that helps B.
C · Oversupply fear. Both companies are adding capital spending and the market worries 2027 capacity crushes margins. Its problem is that it collides head-on with Samsung’s own guidance.
Each branch has an observable tell. If non-memory assets keep outperforming and turnover keeps decaying through declines, that favours A. If the selling spreads into non-AI-hardware sectors and tracks long-end yields, that favours B. If DRAM or HBM spot and long-term contract prices soften, that favours C.
Public data is not yet sufficient to settle among the three. One thing today is certain: the strongest quarterly report in the company’s history bought half a session in this market. Log that one and leave it there. It is not enough to call the cycle.
The first observation is in. The body of this note closes at the July 30 Asian close; the US session that opened after it finished with the worst-hit names bouncing hardest: the semiconductor ETF SOXX +8.50%, Micron +18.36%, Lam Research +17.98%, Microsoft +15.51%. VIX closed at 17.09, down 17.28% — the fear gauge caved the same day. And this was not a rebound that turned in the last hour: the intraday highs held into the close, with Micron up 16.9% midday and 18.36% at the bell, Lam Research up 18.4% midday and 17.98% at the bell. CNBC attributed part of the memory strength to Samsung’s warning that the shortage may run into 2028, so the direction leans toward accepting the company’s guidance. That weakens explanation C, though the same numbers are equally friendly to explanation A: the worst-hit rebounding the most is exactly the shape you would expect after a position flush. Three days down 17%, one day back. The day is finished and it still settles nothing.
