A selloff and rebound overlapped in one week. In this kind of tape, last week's rankings age quickly. Next week's call turns on the four conditions below.
One thing carries from last week into next week.Relative strength in the first week after a sharp selloff is not a reliable sector-selection tool for the following week.
KOSPI −5.10%, KOSDAQ +10.98%. Twenty of 24 sectors outperformed the index; only Electrical & Electronics and its parent Manufacturing category were weaker than the market. The divide was not sector — it was size.
KOSPI· Naver Finance investor-flow data. Sidecar Trading Curb was triggered for four straight sessions from Aug. 3, then stopped on Aug. 7.
Power infrastructure, downgraded in the previous issue, jumped back near the top· Construction, previously dead last, ranked No. 1 of 24· Electrical & Electronics, the only upgrade, finished last.
When leveraged positions are being unwound, selling first hits the names that had risen the most. That is why a one-week ranking can print the opposite of the following week.

| Daishin· 8/6 | August index upside near 9,300; the same report gives a settling range of 6,500–6,800 |
| Hana· 8/3 | Two rebound axes: rates and foreign flows. Forward P/E is at a historical low. |
| Daishin· 8/7 | Semiconductors return as crowding unwinds, joined by lagging sectors. Basis: Q2 non-semiconductor exports +20.3%. |
Among the 72 research notes collected for this issue, most August outlooks point higher. That does not mean downside risk is absent; it describes the distribution of the material we reviewed. A consensus this one-sided is itself something that needs confirmation.
Not “Is it safe to buy now?”
but “What must be confirmed before buying?”Industry-cycle data are already strong,
but two variables remain: flows and next-quarter expectations.
Fundamentals and price have split. The re-entry call comes from flow data, not another strong industry-cycle number.
2027 volumes are locked in by long-term contracts· Only the price fell· Flows, not earnings, determine the re-entry point· Two research notes identify Samsung Electronics' shareholder-return discussion as a potential rerating catalyst.
These numbers arrived before memory did.
Ibiden FY26 Operating-Profit Guidance JPY 127bn· Double YoY· Electronics-Segment Operating-Margin Target 29.3%· 2030 target brought forward by four years· Quarterly Advances Received JPY 154.5bn· Up JPY 73.6bn in one quarter· 35% of this year's capex plan.
Customers prepaid the investment· Post-2029 volumes are already at the contracting stage.

LG Innotek· Daeduck Electronics· Entry into switch-IC market in 2H· Late entrant.
GigaVis· Of Ibiden's JPY 210bn annual investment plan, JPY 20.1bn was spent in Q1· Orders come in 2H.
Orders moved separately while memory prices wobbled.
Hanwha Vision Q2 Operating Profit KRW 65.6bn· +197% QoQ· Driven by SMT equipment and TC bonders at consolidated affiliate Hanwha Semitech· Additional TC-bonder orders for SK hynix· Q3 falls to KRW 48.9bn on one-off costs.
Kiwoom· Undervalued versus 2027–28 HBM growth· Sector top pick.
The first place to show up when utilization rises.
Wonik QnC· Q3 Operating Profit KRW 34.2bn· +327% YoY· The basis is threefold: Pyeongtaek P4 expansion, NAND utilization, and sales to TSMC.
Samick THK· Korea's only mass producer of LM guides and ball screws· Collaborative robots entering wafer transport· Trading resumed in April this year· Start with earnings.
Doosan· Acquiring 70.61% of SK Siltron for KRW 2.3tn· 8.2x EV/EBITDA· vs. an overseas average of 10.5x.

2027 Volume Contracts· 2H FC-BGA Margin· HBM and NAND Prices
SanDisk· Revenue $8.97bn, +372%· Data-center revenue surged 1,298%· Next-quarter guidance of $10.3–10.8bn missed expectations· Down 6.81% in the Aug. 6 regular session.
WDC· Revenue, EPS and guidance all beat expectations· Down 13.03% the same day.
Expectations, not earnings, set the price.
The move reached Korea on Aug. 6: Samsung Electronics fell 6.3%, SK hynix 10.4%, and SK Square 13.3%. On Aug. 7, Samsung Electronics rose 0.22% while SK hynix fell 4.88%, marking the point where stock-specific reactions began to diverge despite the same industry backdrop.
| Source | Thesis |
|---|---|
| SK· 8/3 | P/E says undervalued, P/B says overvalued. ROE quadrupled in 10 months. |
| Hana· 8/3 | The cycle is clearly strong, yet the index has been weak for four weeks. July memory exports +287%. |
| Daishin· 8/6 | Concerns eased after news that 2027 DRAM and HBM volumes were sold out |
| Daishin· 8/7 | One guidance print shook the whole sector. NBM FY27 50% · FY28 two-thirds. |
| Kiwoom· 8/7 | The sector with the biggest earnings surprises had a negative share-price response. Continued in Section 06. |
The first three say it is cheap; the last two say it still does not rise. The dividing line between the camps is the decision threshold.

What range does KRW trade in from here?Intervention only drew a ceiling.
Direction is set by the BOJ rate path.
Japan intervened alone on Jul. 30· Defended USD/JPY at JPY 160.18· The U.S. joined the next day, pushing it into the 157s· The first coordinated action in 28 years since 1998. KRW strengthened too, with USD/KRW at KRW 1,416.
In less than a week, JPY gave back half its gain. Two things intervention did not touch.
The key is not intervention, but the Bank of Japan. The July meeting held at 1.00% (8–1).· Takata argued for a 1.25% hike· Gov. Ueda signaled rate-hike discussions from September· Hana Securities leans to an October hike and leaves room for Japan's 10Y yield to reach 3.0% by year-end.
A hike strengthens JPY, but bond yields also rise in a country planning to spend JPY 370tn.
Conditions BOJ stays on an October hike path· U.S. inflation slows, narrowing the rate gap· USD/JPY 160 as an upper reference
USD/KRW Lower end of the KRW 1,410–1,470 band· Hanwha
Favored Banks· Airlines· Chemicals· Domestic Demand
Disfavored KRW-translated earnings of exporters
Conditions Hike delayed· U.S. rates rise again· Flows that drove KRW strength are exhausted
ADR conversion· Exporters' USD selling· Banks' pre-emptive selling is finite· Hanwha
USD/KRW USD/KRW rises back to KRW 1,480 by year-end· Eugene
Favored Semiconductors· Exporters such as semiconductors and autos
Disfavored FX losses for foreign investors· Import Prices· Strengthens the Aug. 27 BOK hike case
Keep both scenarios open and judge by the signals below.
USD/KRW 1,432 → 1,416· Over the same period, foreign KOSPI net selling totaled KRW 5.93tn· June foreign net outflow from Korean equities: $31.61bn· Daishin· An offsetting structure in which a current-account surplus does not immediately translate into KRW strength and foreign inflows.
FX is a variable that separates sector P&L, not a leading indicator of foreign flows.
This leads into the Aug. 27 BOK meeting. Korea July CPI: 2.8%· Yuanta's 3%-range condition for an early hike was not met· Supports Kiwoom's view: hold, then look to October· Daishin adds a caveat: core inflation accelerated even as headline inflation slowed.
Under A, a stronger KRW lowers import prices and hike pressure; under B, the opposite.
If a country planning JPY 370tn of spending raises rates,
government bond yields jump.
A surge in long JGB yields triggers a yen carry unwind and then
spills into global risk assets.
That is why Scenario A should not be read as unconditionally favorable.
| Source | Thesis |
|---|---|
| SK· 8/3 | U.S. objective: block weakening JGB demand and a rise in long yields. Not a trend reversal, but a measure to prevent sharper further JPY weakness. |
| iM· 8/3 | Pre-empt a second Truss shock and support Korea/Japan investment commitments to the U.S. USD/KRW band: 1,400–1,450. |
| Eugene· 8/5 | Structural weak-yen factors remain, so strength should be short-lived. USD/KRW at 1,480 by year-end. |
| Hanwha· 8/7 | Policy acts as a ceiling that makes upside and downside asymmetric rather than simply lowering the exchange rate. August band: 1,410–1,470. |
| Hana· 8/3 | The ultimate solution is a rate hike. Hold at 1.00% (8–1); Takata argued for 1.25%; October hike possible; 10Y upper end at 3.0%. |
| Daishin· 8/7 | June current-account surplus was $49.73bn but concentrated in semiconductors. Foreign net outflow of $31.61bn was the offset. |
A Treasury secretary memo was caught on camera, with “To Do: Buy JPY” on the top line.
The $5–10bn cited in reports is the number on the memo, not a confirmed execution amount· The Treasury did not disclose the size· There was also an observation that euros, not dollars, were sold to buy yen.
In a market where good earnings are no longer enough,
what criteria should we use?We look at four things.
Guidance· Margin· Free Cash Flow· Speed at Which Investment Converts to Revenue
| Before | Now |
|---|---|
| Last-Quarter Revenue | Next-Quarter Guidance |
| AI Revenue Growth | Return on AI Investment |
| Capex Expansion | Free-Cash-Flow Recovery |
| Industry Growth | Magnitude of Company-Specific Beat |
Look first at the next-quarter range, not last quarter's numbers. Put consensus next to company guidance; the decision line is whether the bottom of the range falls below consensus.
When revenue grows, does operating margin rise too? If revenue grows while margin stays flat, growth costs have not yet been recovered.
During capex expansion, cash signals before net income. This quarter showed cases where cloud revenue growth accelerated to 82%, 43%, and 37% even as cash flow worsened.
The same capex has different revenue-recognition lags by sector. With Big Tech's cumulative capex above $1.1tn, Berkshire's new $30bn-plus position in Alphabet was a vote for the payback period rather than near-term cash flow.
| Case | What Set the Price? |
|---|---|
| SanDisk· WDC | Earnings beat, but next-quarter guidance hit the expectations bar |
| Datadog | Beat and raised, yet fell 19%. Expectations were ahead of earnings. |
| NAVER· Kakao | Revenue rose while profit stalled. AI costs are showing up first. |
| Kiwoom· More than 80% of U.S. companies reporting Q2 beat expectations· Semiconductors and equipment posted roughly 16% EPS surprises, the highest of any sector, yet the average share-price reaction was negative· For software and IT hardware, the correlation between surprises and share-price reactions exceeded 0.9. The expectations threshold sits in a different place for each sector. | |
The question that should come after “data centers are increasing.”Which industry captures orders first,
and which does not recognize revenue until three years later?
DS Investment & Securities, Aug. 7. This is an estimate of cumulative investment over the full plan period, not annual spending.
First decide where buildout comes first. Even if generation capacity remains, the grid cannot connect new load without headroom. Jeonnam,· No. 1 in both power self-sufficiency and solar capacity,· is rated for phased expansion due to grid constraints.
Transmission lines, not power plants, set the sequence.
The first place where price moves.
Third-week August public hearing on the regional electricity-tariff system· Finalized in 2H· Four national tiers based on transmission-use cost, power self-sufficiency, and balanced national development.
August LNG fuel cost: KRW 155.09/kWh· +9.3%· SMP crossed KEPCO's breakeven level of KRW 146.
Once the site and grid are fixed, orders show up first.
Same axis as the construction section in 04· Industrial facilities before housing· Order disclosures lead quarterly earnings.
The first fork is whether starts appear in Yeongnam and Gangwon first.
If the grid is the bottleneck, the largest amount attaches here — and it is already visible in orders.
LS ELECTRIC· Q2 new orders: KRW 2.1tn· +243% YoY· Switchgear 50%, ultra-high-voltage transformers 20%· Backlog KRW 7.0tn, up KRW 1.4tn in one quarter· Fixed contracts with U.S. Big Tech are under discussion.
LS· A holding company linking materials, cable, and equipment in one chain· Consolidated revenue forecast: KRW 27.5tn in 2024 → KRW 43.9tn in 2027· Mirae Asset initiated coverage on Jul. 30.
LS Eco Energy· Q2 revenue KRW 350.3bn, a quarterly record· Busduct revenue KRW 9.8bn, up 158%· Passed prequalification testing for 400kV ultra-high-voltage cable· Orders as early as 2H 2027.
Inference-power demand becomes 24/7 and shifts into storage. This is the same point as the ESS section in 04.
Already visible in June installation data· Standalone systems accounted for 26.8GWh of grid-connected volume· +48.6%· Wind/solar-attached volume declined.
The market is shifting from generation-attached equipment to systems that support the grid itself.
Where the U.S. solar policy in 08 meets Korean renewables.
If dedicated data-center tariffs fall sharply, renewable PPA rates also fall, reducing demand· One caveat applies.
It arrives last, but the money lasts the longest.
TerraPower obtained a nuclear construction permit· Discussions of cooperation with Korean companies were mentioned· Still discussions, not contracts.
AI infrastructure costs are billed not only in electricity, but also in neighbors' sleep.
Microsoft's $7.3bn AI data center was sued over noise in Michigan· It paid ordinance-violation fines and offered to buy residents' homes· The same type of lawsuit has emerged in New Jersey. Siting conflict can delay schedules at any of the six stages above, so we treat it as one potential cause of construction delays.

Section 232· Section 232 of the U.S. Trade Expansion Act.The Commerce Department investigates whether imports threaten national security ·
The President decides on tariffs and import restrictions ·
This case uses a minimum import price instead of a tariff.
About 13 months after the investigation began. The basis was the collapse in the U.S. share of polysilicon production capacity from 50% in 2005 to below 2% in 2024.
The importer must prove that the first independent-party sale price in the U.S. MIP is at or above the required level
The first point where the price floor enters ASPs. Contract terms set here determine later revenue.
Because the increase accrues to seller margin rather than government tax revenue, the gap between the floor and the market price remains with the seller.
| Product | MIP | Reference |
|---|---|---|
| Polysilicon | $21 / kg | Current China price: about $4/kg |
| Ingots· Wafers | $100 / kg | About 1.5x the market price |
| Solar Cells | $0.22 / W | Additional 15% tariff on derivative products |
| Modules | $0.38 / W | Imported module prices rise from the low-$0.30s range |
| Derivative-product tariffs are 15% for Korea, Japan and the EU, and 10% for the U.K. Polysilicon itself is subject only to the MIP, with no tariff. Based on Kyobo's calculations. | ||
Malaysian feedstock is exempt from the tariff, while the MIP directly becomes an ASP floor for both polysilicon and wafers. This is the shortest path from policy to price.
Georgia capacity captures higher U.S.-made module ASPs, followed by the benefit of internalizing cell production. Because this sits at the module stage, it passes through one additional contract-renewal cycle.
| Stock | YTD |
|---|---|
| SK Eternix | +165.7% |
| HD Hyundai Energy Solutions | +145.0% |
| OCI Holdings | +111.8% |
| Hanwha Solutions | +20.3% |
| KOSPI | +49.4% |
| Kyobo Securities, as of Aug. 7. The same note concludes that the biggest policy uncertainty for 2H has been resolved. Hanwha Solutions' YTD gain being smaller than the index is part of the basis for the ordering above. | |
These are not quarter-defining narratives; we selected only developments that can move the prices and earnings of specific sectors first.
Water level at a record low· Disruptions to German petrochemical feedstock procurement· If Europe's isocyanate (TDI/MDI) procurement shortage persists, volume shifts to alternative suppliers.
Watch both Rhine water levels and European spot prices. If water levels recover, the thesis disappears; this is a short-term variable.
U.S. proposal to block new imports of Chinese optical transceivers for data centers· Target announcement by year-end· Top three Chinese vendors hold a combined 60% share of 800G optical modules· If finalized, substitution demand would be large.
Technology decoupling continues regardless of the late-September U.S.–China summit· Meritz.
July base-oil export unit price +17%· Margin spread at a record high· Driven by Middle East refinery outages· It reverses when the facilities restart.
Refining margins are reflected with a one-month lag· Watch Q3 earnings for the impact on refiners' P&L. Strength is expected to persist through 2H.· Hana.
First· Who Was Trapped?
“The index fell” and “the market fell” are not the same statement. If you cannot identify where the noise is coming from, you will get lost in the same place next week.
Second· Customer Advances
| Who | The industry's No. 7 funeral-service company Bumo Sarang |
| What Money | Customer advances KRW 59.5bn· Money subscribers prepaid for their own funeral services |
| Where | U.S.-listed 2x Leveraged ETF· A product that tracks twice the daily move of BitMine, a company accumulating Ethereum |
| What Remained | Book value at end-2025 KRW 10.2bn· Valuation loss KRW 49.3bn, about 83% of principal |
| Industry | Of 75 funeral-service firms nationwide, 32 have total assets below customer advances· KRW 11tn market· 11mn subscribers |
| Regulation | Because the industry falls under the Korea Fair Trade Commission, it is effectively outside financial regulators' prudential rules· 50% of customer advances can be invested freely |
An individual buying a 2x leveraged ETF must complete prior education, a three-hour mock-trading course, and post a KRW 30mn base deposit. A corporation investing KRW 59.5bn of other people's funeral money faced no such requirements.
Reported May 18, 2026· Book value is as of end-2025. This is an unrealized valuation loss, not a realized loss, and reported loss figures differ by media outlet.
We test only the proxy indices designated in advance last week. The criteria are also unchanged from last week: relative strength of +1.0%p or more / market-like within ±1.0%p / relative weakness of −1.0%p or less. The price score is the sector's weekly return minus the KOSPI's −5.10% weekly return.
| Axis | Predefined Criterion | Result |
|---|---|---|
| 01 · U.S. QRA | Coupon issuance up / unchanged or lower | 8/5 refunding: $125bn Held unchanged, with no increase Unchanged / Lower |
| 02 · U.S. 10Y | Weekend close above / below 4.745% | 8/6 final: 4.670% Carried to the next issue |
| 03 · Electrical & Electronics | Sector weekly return − KOSPI weekly return, ±1.0%p | −11.04% − (−5.10%) = −5.94%p Relative Weakness· Downgrade |
| 04 · Foreign Cash Flow | KOSPI five-session cumulative flow; whether it turns net positive | −KRW 5.93tn; no turn Not Met |
| AI data centers remain off the candidate list, as previously designated. Banks, previously deferred, posted +5.56% in the KRX Banks index this week. Axis 04 carries over unchanged as the first line of Section 03. | ||
The previous issue set two break conditions. If the U.S. Treasury does not increase long-duration issuance, tension in the rates axis eases.· If employment collapses, earnings — not rates — become the problem.
The first condition occurred. The Aug. 5 refunding was held unchanged with no increase.
The index fell even after that tension eased, so rates were not the cause of this week's decline.
Deleveraging filled that explanatory gap.
Margin-financing balance: KRW 37.5tn on Jun. 24 → KRW 27.6tn on Aug. 5· Semiconductor Top2 leveraged ETF average daily turnover: KRW 7.5tn → KRW 0.6tn on Aug. 6· Samsung Electronics and SK hynix market-cap weights fell versus June to 27.08% and 24.08% in July· On Aug. 7, turnover was 79% of the five-day average while the short-selling share rose from 3.6% to 6.2%.
SK Securities · 8/3· Stock-picking after deleveraging. Hana Securities · 8/5· The end of deleveraging, the start of alpha.
The wording differs, but the conclusion is the same: this is a phase of stock differentiation rather than an index-direction trade.

KOSPI sector indices are market-cap weighted, while KRX series/theme indices use different methodologies. We do not aggregate or directly compare the two families; each table is prefixed with its index family.
For flows, total and five-session cumulative figures come from Naver Finance investor data, while stock-level figures come from the KRX regular market series. They are not mixed within the same card, and no shares are calculated across the two.
USD/KRW uses the 15:30 close in Korea's onshore weekly FX session. The JPY/KRW base rate is omitted because it belongs to a different series. Weekly returns are index-to-index, from the Jul. 31 close to the Aug. 7 close.
Stock names cited in the body are those appearing in brokerage research and are not buy recommendations from this report. Target prices are omitted because brokerages can differ even on the same stock.
