Intel −28.6% While SK Hynix Posts Record Profit: The Two Sides of Expensive Memory

In the last week of October 2026, two chipmakers reported results driven by the same force and got opposite verdicts from the market. On October 28, SK Hynix, one of the world's largest memory makers, reported preliminary third-quarter operating profit of 83.33 trillion won, up 632% from a year earlier, with an operating margin of 79.7%. Its shares rose 10.9% in Seoul that day. On October 29, after the US close, Intel beat third-quarter profit forecasts but guided well below expectations for the fourth quarter. On October 30, its shares fell 28.6% to $65.76. The common thread is the price of memory: for a company that sells memory it is revenue, for an industry that has to buy it it is a cost.

Intel: A Beat on the Quarter, Punished on the Outlook

Intel's third quarter was good on its own terms. Revenue was $16.5 billion, up 21% year over year, and adjusted earnings per share came in at $0.52 against the $0.40 analysts expected, according to LSEG data cited by CNBC. The Data Center and AI division grew 78% to $7.3 billion, which CFO David Zinsner called the company's strongest data center growth in 15 years. The weak spot was the PC business: Client Computing revenue fell 5% to $8.1 billion and missed estimates.

The outlook is what moved the stock. For the fourth quarter Intel guided revenue of $15–16 billion against about $17.1 billion expected, and adjusted EPS of $0.25 against $0.43. The adjusted gross margin is expected to drop to 38.0% from 44.1%. Zinsner said the company sees "the PC slowdown continuing at least through the first half of next year." Part of the gap is a one-off: an explosion at Intel's fab in Israel earlier in October killed two workers and shut the plant down, and Zinsner put the lost revenue at about $600 million over two quarters. According to Investing.com's summary of the presentation, the shutdown accounts for about 2 percentage points of the fourth-quarter margin decline.

On October 30 Intel closed 28.58% lower, its worst day since 1974, according to CNN. The stock had gained about 150% in 2026 before the report, though it had already lost about 23% in October. CNN reported that an index of chipmakers fell 7.2% that day, the Nasdaq Composite 2.86% and the S&P 500 1.82%. As with Netflix a week earlier, the market priced the next quarters, not the one just reported.

SK Hynix: A Record Built on the Same Shortage

SK Hynix's preliminary third-quarter revenue was 104.6 trillion won (about $78 billion at the October 28 exchange rate, by our calculation), up 328% year over year. It is the company's first quarter above 100 trillion won and more than its revenue for all of 2025. Operating profit of 83.33 trillion won beat the 76.26 trillion won consensus compiled by Yonhap Infomax by 9.3%. According to Investinglive, average DRAM selling prices rose by a high-20% rate from the second quarter and NAND prices by a mid-20% rate. The company named shipments of HBM4, the high-bandwidth memory used in AI accelerators, and server DDR5 as the main drivers.

The company is turning much of that cash over to shareholders: about 100 trillion won in total for 2026, including more than 30 trillion won in dividends and more than 60 trillion won in buybacks and share cancellations. The third-quarter dividend is 20,000 won per share, half of it a special payout from gains on a partial sale of its Kioxia stake, and the board approved a new 20 trillion won buyback. The company's outlook, The Korea Times reported, projects memory shortages through 2030. That is a forecast, not a fact, though it rests on long-term supply agreements with 14 major customers.

One Input Cost, Two Sides of the Ledger

The mechanism is simple. AI data centers buy huge volumes of HBM and server memory, memory makers shift capacity toward those products, and supply for everything else gets tight. Prices rise across the board. For SK Hynix that goes straight into its margin, because its costs barely change when the selling price rises.

For the PC industry the same price is a cost. Every laptop needs memory, so PC makers either raise prices and sell fewer units or absorb the cost and earn less. CNBC, citing Counterpoint Research, attributed a 4% drop in global PC shipments in the second quarter to "soaring costs for memory and other components." Fewer PCs means fewer Intel processors: Intel's presentation cited industry-wide memory shortages shrinking its addressable market and pointed to a client computing decline of more than 20% from the third quarter to the fourth.

Intel itself sits on both sides. Its data center chips benefit from the same AI spending, while its PC chips suffer from the side effect. The market judged that the second effect dominates the next two quarters.

Why a Broad Semiconductor ETF Hides the Split

A sector fund holds both memory sellers and memory buyers. When the price of one input shifts profit from one group to the other, gains and losses partly cancel inside the fund, so its return looks calm while individual holdings move by tens of percent. A 7.2% drop in a chip index and a 28.6% drop in one of its members are very different experiences for the investor.

Diversification has limits, though. On October 30, stocks that benefit from expensive memory fell too: before the US open Micron was down nearly 5%, according to StockTitan. In a sharp selloff investors sell the whole sector, and correlations rise exactly when protection is needed. We saw the same pattern in June, when Broadcom's guidance miss pulled down the entire chip sector.

Memory Super-Cycles: Concentration and Cyclicality

Memory is closer to a commodity than most chips: products from different makers are largely interchangeable, so price is set by the balance of supply and demand. A 79.7% operating margin reflects a shortage, not a permanent level. When new capacity arrives or demand slows, prices can fall just as fast, as we explained in our post on the memory supercycle debate in May.

Concentration adds to the risk. The Korean market depends heavily on Samsung and SK Hynix: on October 28 the Kospi rose 6.63% to 6,012.44 on the back of the results, according to The Korea Times, after a selloff in chip stocks driven by fears that the memory boom was peaking. An investor in a Korean index fund is betting largely on the memory cycle, as we noted in our post on the Kospi record.

For investors in Ukraine, the same applies to US sector ETFs bought through a broker, plus currency risk: the return in hryvnia also depends on the exchange rate, which recently hit a record low.

Practical Takeaway for Investors

1. Look for the input cost. When a key component gets more expensive, ask who sells it and who buys it. In the same industry the answer splits companies into winners and losers.
2. Read the guidance, not just the beat. Intel beat on the quarter and still lost more than a quarter of its value, because the price reflects expectations for the coming quarters.
3. Know what your fund holds. A broad semiconductor ETF smooths out the split between memory makers and memory buyers, but it does not protect against a sector-wide selloff.
4. Treat record margins in a cyclical business with caution. Shortage forecasts through 2030 are the company's view, and memory cycles have turned before.
5. Watch concentration. If a fund or index depends on two or three companies in one cycle, your portfolio depends on them too.
