Memory Stocks Slide as SK Hynix Record Q2 Misses Analyst Bar

SK Hynix delivered record Q2 profit and still fell 9.6%. Kospi -8%, Micron below 813. Memory bear market meets Fed day, MSFT + META tonight.

TLDR

SK Hynix delivered the most profitable quarter in its history and its stock still fell 9.6 percent in Seoul, dragging the Kospi down another 8 percent to a four-month low. Revenue of 79.32 trillion won and operating profit of 60.54 trillion won were both records, but analysts were positioned for 84 and 64 trillion won respectively. Micron closed Tuesday below 813 dollars after CXMT’s 466 percent Shanghai debut and a Wall Street Journal report that Apple has asked Washington for waivers to source memory chips from CXMT and YMTC. The semiconductor index – SOX is now roughly 9 percent from bear market territory. Wall Street heads into Fed day with MSFT and META reporting after the close, then AAPL, AMZN, June PCE, Q2 GDP advance, and a Bank of Japan decision all landing on Thursday.

Market Regime

The memory trade that led every AI ranking through the first half of 2026 has broken. Since late June, SanDisk is off around 50 percent, SK Hynix ADRs around 47 percent, Micron and Western Digital more than 32 percent each, and Seagate about 30 percent. The Roundhill Memory ETF – DRAM, which is 72 percent Samsung, SK Hynix, and Micron combined, has followed the same path. Around 1.5 trillion dollars of semiconductor market cap has been erased since June 25. What used to be a sold-out, capacity-constrained supercycle is now being re-priced against a real Chinese competitor with fresh capital, a possible Apple sourcing shift, and a Fed meeting arriving at exactly the wrong moment.

Positioning is defensive and rotational, not risk-off. Tuesday’s tape saw the equal-weighted S&P 500 print a fresh record while the cap-weighted index sat flat and the SOX fell more than 6 percent intraday. Staples, healthcare, and materials caught the rotation flows. Wednesday’s setup is binary: a Fed hold with a hawkish-lean statement can add a second leg to the semi drawdown, and Warsh’s press conference at 12:00 AM IST will do most of the work. MSFT and META capex commentary lands right after. The bar has moved from headline beats to guidance on 2027 AI infrastructure spend.

Bullish Factors

• SK Hynix set fresh company records in Q2 with revenue up 257 percent and operating profit up 557 percent year on year. The company explicitly rejected the AI-peak narrative on its call and pointed to HBM4 mass shipments and long-term agreements now signed with roughly ten strategic customers.
• Analysts at Counterpoint Research and Morningstar continue to argue that CXMT’s threat is real in commodity DRAM and NAND but limited in HBM. Chinese suppliers may not manufacture HBM3 until the first half of 2027, by which point Micron, SK Hynix, and Samsung are expected to be shipping HBM4.
• Wall Street’s Micron consensus 12-month target still sits around 1,569 dollars against a Tuesday close of 812.48, with 29 of about 33 covering analysts at Strong Buy. Non-cancelable HBM contracts worth roughly 22 billion dollars remain in place through 2026.
• Hong Kong’s Hang Seng gained 1.8 percent and the Shanghai Composite added 0.4 percent Wednesday, a signal that mainland money is not treating CXMT’s rise as a systemic risk.

Bearish Factors

• SK Hynix missed on both lines. Consensus was 84 trillion won of revenue and 64 trillion won of operating profit; the print came in at 79.32 and 60.54 trillion won. The stock closed Wednesday at 1.4 million won, down 9.61 percent, its fourth double-digit single-session drop of July.
• Kospi is now down about 29 percent in a month and has entered bear market territory. Wednesday saw another 8 percent leg lower, with SK Hynix off 12.6 percent intraday and Samsung down 8 percent. Two consecutive circuit-breaker days have prompted a public apology from Korea’s finance minister on single-stock leveraged ETFs.
• The Wall Street Journal reported that Apple has asked the US government for waivers to source memory chips from CXMT and Yangtze Memory Technologies for non-US products. If granted, that shifts pricing power meaningfully away from the incumbent trio.
• Reports of Chinese domestically-produced DUV lithography machines add a self-sufficiency overlay that pressures the entire Western semiconductor stack, not just memory.
• Front-month WTI is bid on renewed Middle East risk. A hawkish Warsh has cover from oil-driven inflation to signal September optionality.

Asian Markets This Morning

Kospi closed down about 8 percent midday at 5,531.56, its lowest level since early April. SK Hynix ended Wednesday’s cash session down 9.61 percent at 1.4 million won, and Samsung Electronics fell 8 percent. Two circuit-breaker triggers in as many days pushed Korea’s finance minister to publicly apologize for the retail-heavy single-stock leveraged ETF regime that has amplified moves in both directions.

Japan’s Nikkei 225 finished off 1.5 percent at 61,434.19 after giving up early gains. Tokyo Electron dropped 10.6 percent, Lasertec fell 8.3 percent, and Kioxia was down about 8 percent as the semiconductor equipment complex followed Korean memory lower. Taiwan’s Taiex shed 3.8 percent on TSM and packaging weakness. Hong Kong bucked the region: Hang Seng closed up 1.8 percent at 25,762.80 and Shanghai Composite reversed early losses to finish 0.4 percent higher at 3,830.02, with mainland investors seeing CXMT’s arrival as a domestic tailwind rather than a systemic risk.

What Moved Wall Street Today

Tuesday delivered one of the sharpest intra-day rotations of the year. The equal-weighted S&P 500 hit a fresh record while the cap-weighted index closed roughly flat at 7,431, up 0.26 percent. The Dow added about 1 percent as Coca-Cola led staples higher and defensive sectors caught the rotation flows. Underneath, the SOX fell 6.4 percent intraday and the technology sector – XLK shed 3.8 percent. The Nasdaq 100 slipped again, its third straight session lower and enough to put semis on pace for their worst month since 2002.

Micron closed at 812.48, off 9.74 percent after touching an intraday low of 789. The stock broke the 803.95 support that had held since early July, with 742 the next technical shelf. SK Hynix ADRs – SKHY closed at 130.49, an all-time ADR low, off 8.76 percent. SanDisk gave up 12 percent, Western Digital dropped 7 percent, and the DRAM ETF fell about 4 percent. AMD, Intel, and Arm all traded lower on sympathy. AAPL climbed against the tape ahead of Thursday’s report and briefly crossed 5 trillion dollars in market cap for the first time.

Assets in Focus

DRAM – Semiconductor Memory Index

The Roundhill Memory ETF is now more than 20 percent below its late-June high, meeting the technical definition of a bear market for the group. Samsung, SK Hynix, and Micron together are 72 percent of the fund, so single-name earnings prints move it more than a typical sector ETF. Wednesday’s IST overnight tape has already delivered the SK Hynix miss and the Kospi cascade. The next fundamental data point is MSFT and META capex commentary tonight.

NVDA

Nvidia is the demand side of the HBM story that has powered SK Hynix and Micron. The bull case for the memory group and the bull case for Nvidia are the same trade: hyperscaler AI capex has to keep expanding through 2027. Any Fed hawkish tilt that pressures long-duration tech multiples, or MSFT or META capex language that signals a plateau, hits NVDA first. Earnings August 26.

AAPL

Apple crossed 5 trillion dollars in market cap Tuesday, a first for any US listed company. The story is bifurcated: Apple is likely a beneficiary of any CXMT sourcing waiver on cost of goods, but the reputational and geopolitical friction is real. Q3 fiscal print lands Thursday after the close, with iPhone units, services growth, and any commentary on China memory sourcing the three watch points.

MSFT and META

Both report after Wednesday’s close, arriving late night IST. Guidance on FY27 AI capex is the number that matters more than headline EPS. Meta’s Compute infrastructure framing has already been cited in the past week as one of the triggers for the memory drawdown, and MSFT’s Azure AI segment guide feeds directly into HBM demand projections.

NSDQ100

Third straight session lower and now at a one-month low. The semiconductor weight inside the index is doing most of the damage. A dovish Fed presser can produce a technical bounce, but the Thursday overnight combination of BoJ, Q2 GDP, June PCE, plus AAPL and AMZN prints makes any Wednesday rally hard to sustain into the weekend.

Index Levels to Watch

Kospi: 5,531 midday, prior support 5,500. A break there opens 5,300.

NSDQ100: prior support around 24,900 tested Tuesday, next shelf near 24,500. Third straight lower close puts the 50-day at risk.

S&P 500: 7,431 close leaves the 7,400 psychological line as the first pivot. A hawkish Warsh statement puts 7,350 in play.

DRAM ETF: 20 percent below the June high, roughly 54 dollars. Confirmation of the bear market print, with any recovery needing to reclaim 60 to reset.

SOX: still about 9 percent above the bear market threshold. Watch for the 15,900 area on any further semis leg lower.
