TL;DR - SK Hynix (000660.KS / SKHY) hosts its Q2 2026 earnings conference call on Wednesday July 29 at 9 AM KST — FnGuide consensus targets operating profit of ₩64.2 trillion (+597% YoY vs. ₩9.21 trillion in Q2 2025), with the bull case reaching ₩69.0 trillion (KB Securities, 77% margin). - Samsung Electronics (005930.KS) and LG Electronics (066570.KS) release full Q2 segment breakdowns on Thursday July 30 — Samsung's preliminary OP of ₩89.4 trillion (+1,810% YoY) needs credible HBM4 revenue disclosure to re-rate; LG's ₩1.58 trillion (+147% YoY) needs to strip out a one-time ₩300 billion tariff refund. - KOSPI closed at 7,150.26 (+5.96%) on Wednesday July 22, recovering from a -4.48% intraday plunge to 6,515.24 on July 20; SK Hynix briefly touched ₩1,990,000 intraday, approaching the psychologically important ₩2 million level. - The SKHY ADR (Nasdaq, listed July 10) carried a 33% premium over the KRX-implied value ($164.60 vs. approximately $123.94) as of July 22 — elevated ahead of results, likely to compress post-announcement.
Market Context Going Into the Week
Korea's equity market enters the last week of July riding a whipsaw recovery. KOSPI logged an intraday decline of -4.48% on Monday July 20 — touching a trough of 6,515.24 — as the Philadelphia Semiconductor Index entered a technical bear market (-20.2% from its June 22 peak). On Wednesday July 22, the index staged a +5.96% session gain (measured close-over-prior-close) to 7,150.26 as global chip benchmarks rebounded overnight and SK Hynix pre-positioned ahead of next week's earnings. July 2026 has already recorded more than seven circuit-breaker events and thirty sidecar triggers — the most volatile KOSPI month since early 2020.
Against that backdrop, the market is squarely focused on whether the AI-driven memory supercycle — which powered SK Hynix to record Q1 2026 results (OP ₩37.61 trillion, 72% margin) — can sustain or accelerate in Q2 as HBM4 enters commercial shipment.

July 29: SK Hynix — The Week's Centerpiece
Consensus and Bull/Bear Range
SK Hynix enters its Wednesday July 29 conference call with the most-watched earnings in Korea's 2026 season. FnGuide's consolidated sell-side estimate puts Q2 operating profit at ₩64.2 trillion on revenue of ₩83.9 trillion, implying a sequential jump from Q1 2026's ₩37.61 trillion in OP and ₩52.58 trillion in revenue — a quarter-over-quarter increase of approximately +70.7% in operating profit.
KB Securities, among the most bullish brokerages, projects ₩69.0 trillion in operating profit and an operating margin of 77%, with segment-level margins of 81% for DRAM and 66% for NAND Flash, driven by average selling price increases of more than 50% QoQ. The bear case comes from Mirae Asset at approximately ₩60.4 trillion.
| Scenario | Q2 2026 OP | Margin | YoY vs. Q2 2025 (₩9.21T) |
|---|---|---|---|
| Bull (KB Securities) | ₩69.0T | 77% | +649% |
| Consensus (FnGuide) | ₩64.2T | ~77% | +597% |
| Bear (Mirae Asset) | ₩60.4T | ~73% | +556% |
Three Questions Investors Are Asking
1. How large is the HBM4 revenue contribution in Q2?
SK Hynix supplies approximately 70% of Nvidia's HBM4 requirements for the Vera Rubin platform, and Samsung signed an HBM4 supply MoU with AMD in March for the Helios AI rack (confirmed live on Azure in July). Q2 2026 may be the first quarter to meaningfully separate HBM4 (versus HBM3E) revenue. Management's commentary on HBM4E sampling timelines — and whether supply remains deliberately constrained — will be a primary post-call discussion topic.
2. Is NAND Flash margin recovery durable?
KB Securities' 66% NAND margin assumption would represent a full recovery from the loss-making conditions of 2024. SK Hynix's eSSD product for AI data centers (launched at its July 10 Nasdaq listing ceremony in New York) is the forward narrative here. Any guidance on enterprise SSD pricing trends into H2 will be closely followed.
3. What does management say about H2 supply discipline?
Memory is a volume-sensitive commodity: consecutive supply cuts in 2024–2025 enabled the current supercycle. The structural risk is that Samsung, Micron, and China's CXMT add capacity faster than AI-driven demand can absorb. SK Hynix management's language around H2 2026 supply positioning will likely drive post-results stock movement more than the Q2 numbers themselves.
SKHY ADR: Premium Likely to Compress Post-Results
As of July 22, SKHY (Nasdaq) traded at approximately $164.60 — approximately 33% above the KRX-implied ADR parity value of approximately $123.94. At its July 10 listing, the premium was approximately 16%; it peaked above 50% during intraday volatility in mid-July.
Strong results may paradoxically compress the ADR premium via "buy the rumor, sell the news" dynamics: U.S. institutional investors who drove the Nasdaq premium may rotate back into KRX-listed shares or take profits if HBM4 guidance is cautious. Korean active ETFs (11 products had added SKHY exposure by July 16) create an additional feedback loop between the two venues.
July 30: Samsung Electronics — Segment Breakdown in Focus
Samsung's preliminary Q2 2026 guidance (released July 7) placed consolidated operating profit at ₩89.4 trillion — the largest quarterly profit in the company's history, and a +1,810% YoY increase — driven almost entirely by the memory-heavy DS Division where HBM and DRAM pricing surged. Consolidated revenue was estimated at approximately ₩171 trillion. The market's initial reaction on July 7 was a 7% stock decline, reflecting concerns about HBM yield versus SK Hynix and DX Division margin pressure.
The Thursday July 30 full release provides the segment data investors need to assess earnings quality:
| Division | What to Watch |
|---|---|
| DS (Device Solutions / Memory) | Share of ₩89.4T from HBM4 vs. commodity DRAM/NAND; yield improvement disclosure |
| DX – MX (Mobile) | Margin recovery post-Q1 2026's ₩2.8T OP; Z Fold 8/Z Flip 8 ASP impact |
| SDC (Samsung Display) | Large OLED share vs. LG Display; iPhone 18 Pro ramp volume |
| Harman (Automotive) | EBIT margin; automotive infotainment backlog |
DRAM average selling prices rose approximately 44% QoQ in Q2, and NAND flash climbed 53% QoQ (Citi Research) — with Samsung's DRAM capacity at roughly 38.6% market share (Q1 2026, Counterpoint), these tailwinds are material for the DS segment. S&P's July 22 decision to raise Samsung's credit outlook to Positive (from Stable), citing the sustained improvement in memory pricing and Samsung's strengthened balance sheet, reinforces the memory supercycle thesis.
The key overhang: Samsung has not confirmed commercial HBM4 shipments at scale. Any disclosure of HBM4 volume or a timeline for HBM4E qualification at Nvidia or AMD would narrow the valuation gap to SK Hynix. The analyst community shows 36 Buy ratings and 3 Hold with an average target of ₩305,000 (vs. ₩273,000 July 22 close), implying approximately 12% upside — but re-rating requires HBM narrative clarity.
July 30: LG Electronics — Structural Profitability Under Scrutiny
LG Electronics released preliminary Q2 2026 results on July 7: ₩1.58 trillion in operating profit (record Q2 high, +147% YoY) on revenue of ₩23.83 trillion (+15% YoY, record Q2 high), beating the analyst consensus of ₩1.42 trillion OP (beat by approximately 11.3%) and ₩22.79 trillion revenue (beat by approximately 4.6%).
The July 30 conference call will provide four-division detail:
- H&A (Home Appliance & Air Solution): Record European heat wave drove HVAC and heat pump demand; premium appliance and subscription-model revenues.
- MS (Media & Entertainment): webOS advertising platform, now monetized across 140+ countries.
- VS (Vehicle Solutions): Automotive infotainment order book; management has guided VS to structural profitability by year-end 2026.
- BS (Business Solutions): HVAC commercial units and B2B services.
Investors' primary concern: approximately ₩300 billion in one-time U.S. tariff refunds was included in Q2 results. Excluding this non-recurring item, operating profit would be closer to ₩1.28 trillion — approximately 9.9% below the ₩1.42 trillion consensus and well below the headline figure. The structural question is whether LG can sustain ₩1.0 trillion+ quarterly operating profit through H2 2026 without tariff tailwinds. Analyst confidence in the "structurally ₩1T OP company" narrative drove the stock higher in July; the VS segment profitability update is the confirmation signal.
Side Story: Homeplus — Rehabilitation or Liquidation?
South Korea's No. 2 hypermarket chain Homeplus (MBK Partners, private equity-owned) remains in legal limbo. The Seoul Bankruptcy Court terminated rehabilitation proceedings on July 3, citing failure to secure operating funds. A subsequent 14-day ultimatum led MBK Partners and Meritz Financial Group to provide ₩200 billion ($135 million) in emergency DIP financing on July 16, enabling Homeplus to file an appeal at the Seoul High Court on July 20.
If the High Court restores rehabilitation, Homeplus restarts a restructuring plan targeting a narrowed 67-store hypermarket footprint. If rejected, liquidation proceedings begin — affecting 12,000 employees, supply-chain creditors, and real estate assets (Homeplus properties are largely sale-leaseback structures). Listed hypermarket competitors E-mart (139480.KS) and Lotte Shopping (023530.KS, operator of Lotte Mart) face an asymmetric outcome: orderly restructuring means continued competition; liquidation creates a sudden store-count reduction and real estate market pressure.
Investment Implications
SK Hynix (000660.KS / SKHY): Results at or above ₩64 trillion confirm the supercycle thesis. Results in the ₩60.4–63 trillion range — below the ₩64.2T consensus but at or above the ₩60.4T bear case — would be viewed as a modest miss. A result below ₩60 trillion, or cautious H2 HBM guidance, would likely mean a sharp reversal from the July 22 recovery. Upside surprise with specific HBM4 volume commentary could push SK Hynix toward ₩2,000,000 on KRX. The SKHY ADR premium at 33% builds in substantial expectations — position sizing should account for both outcomes.
Samsung Electronics (005930.KS): Segment data is the unlock. Strong DS Division disclosure — including any HBM4 yield or customer qualification news — closes the narrative gap to SK Hynix. DX Division guidance on Galaxy Z Fold 8 / Z Fold 8 Ultra and Z Flip 8 pre-orders (post-Unpacked London, July 22) adds a mobile wildcard. With 36 buy ratings and a ₩305,000 average target, the stock is positioned for re-rating if HBM clarity emerges.
LG Electronics (066570.KS): The structural story hinges on VS segment profitability timing. A confirmed VS EBIT-positive quarter would support multiple expansion toward premium-conglomerate peers. If H2 guidance is maintained at ₩1T+ OP excluding tariff effects, LG Electronics qualifies as a defensive within Korea's earnings week lineup.
Key Risk Factors
- U.S.-China export controls: Any new HBM or advanced DRAM export restriction targeting Chinese AI customers would disrupt SK Hynix's Q3 supply allocation and is the single largest tail risk for Korean chipmakers.
- FX exposure: KRW/USD at 1,480.2 on July 22. Korean memory exporters' dollar revenues translate back at margin-accretive rates during KRW weakness — a rapid KRW appreciation (Fed pivot risk) compresses won-denominated earnings.
- Earnings-season overhang: If Kia (Friday July 24) or the large financial groups disappoint, KOSPI could test support at 6,900 before the SK Hynix catalyst on Wednesday July 29, creating entry opportunities for patient investors.
