0. Today's One-Line Summary

The strongest holiday news is macro: the China-US presidential summit produced a consensus of eight deliverables (9/23–9/25, including a "USD 30 billion reciprocal tariff-reduction arrangement", the trade truce extended to January 10, 2027 (per the US Treasury Secretary; China has not denied it), and an AI dialogue mechanism), directly repairing risk appetite across global markets; on A-shares' previous trading day (9/24) the market had just suffered a panic flush — a net main-force outflow of RMB 65.2 billion (largest in 31 days) — with the broad-market sentiment index at 18.97, extreme fear. A macro tailwind slamming into an ice point in sentiment: a gap-up repair is highly likely today.

But three discounts must be laid on the table at the same time: ① the export chain already rallied once on 9/17 on the "USD 30 billion tariff-reduction talks" (跨境通 (Globalegrow, 002640) +9.91%, 新泉股份 (Xinquan, 603179) +7.27%); this round is a second fermentation from "talks → summit endorsement", and the final list of tariff-reduced goods has not been published; ② the 30-year US Treasury yield broke above 5.5% on Friday (first time since 2004), and the 10-year at 5.16% set another high since 2007; the probability of an October Fed rate hike has risen to 69.7% (per CLS on 9/24) — external valuation pressure has not lifted; ③ only 3 trading days remain before the holiday: a gap-up is a window for cash-holding funds to take profits, not a signal for momentum-chasing funds to be handed money.

By branch, the holiday news meshes with where the 9/24 tape money flowed: oil tankers / oil & gas (Trump on Saturday rejected Iran's "reopen Hormuz within 7 days" proposal → crude has already been re-priced this morning: Brent +1.9% at USD 106.30, WTI +1.23% at USD 93.55 (read at 07:25); but Axios says US-Iran could resume talks as early as Monday, and the third point of the China-US consensus — "no country may levy tolls on international waterways" — is a cooling factor: two-way volatility — trade freight rates, not the direction of oil); memory (US stocks broadly higher Friday + Solidigm rumored USD 150 billion IPO + Micron 9/30 earnings — DRAM/NAND contract prices rising for four consecutive quarters are the hardest fundamentals in the entire market); robots (Tesla Optimus output up roughly 10x + a new round of China supply-chain audits; on 9/24 the robot-actuator concept already saw a net inflow of RMB 1.04 billion).

Pre-market call: gap-up repair, led by "oversold + real orders / real earnings" names (memory, optical-module leaders, oil tankers), not high-position themes (the media high-flyer cluster, the two-consecutive-limit-up packaging-materials plays). In the 9/24 limit-up ladder, almost everything above 3 consecutive boards was publishing & media (内蒙新华 (Inner Mongolia Xinhua, 603230) 6 boards in 7 days, 新华文轩 (Xinhua Winshare, 601811) 5 boards, 新华传媒 (Xinhua Media, 600825) 4 boards) + textiles (泰慕士 (Taimus, 001234) 4 boards) + home appliances (奥佳华 (OGAWA, 002614) 4 boards); Xinhua Winshare has already received a regulatory work letter from the Shanghai Exchange, and Xinhua Media itself flagged restructuring uncertainty — the high-flyer cluster is the group with the largest ebb-risk today. On positioning: the repair offers a chance to sell old and buy new, not the courage to go full-position into the holiday.

2. Strongest bullish branches, ranked

Branch deep-dives: judgments that must be spelled out

(1) The China-US consensus: a "landing confirmation", not a "first discovery". The USD 30 billion reciprocal tariff-reduction framework was first raised at the May leaders' meeting, advanced by the Ministry of Commerce in July, confirmed as under consultation at the 9/10 MOFCOM regular meeting, and the A-share export chain already rallied one round on 9/17 (跨境通 +9.91%, 新泉股份 +7.27%, 爱柯迪 +6.77%, 拓普集团 +4.36%). This holiday's increment: summit endorsement, written into the eight-point consensus, trade truce extended to 2027/1/10 (per the US Treasury Secretary), AI dialogue mechanism. Treat it as a "second fermentation of old news", downgrade it, do not treat it as brand-new bullish news; moreover the final goods list is unpublished, so direct beneficiaries cannot be pinned to tariff lines — this round of repair is more about risk appetite and export-chain beta. The US list (US exports to China benefiting: agriculture / energy / Boeing chain) and the China list (light industry & textiles / home appliances / consumer electronics / cross-border e-commerce) are useful directionally, but the scale is only USD 30 billion on each side, limited relative to total China-US trade volume — a signal, not a flood.

(2) Oil tankers: trade "freight rates + transit volumes", not "headlines". This Hormuz rally is 7 months old; the structure is "transport disruption without production cuts": strait transit was once -77%, global supply only -4%, and half the price gain is a transport-route premium (Xueqiu supply-chain tracking). This means: ① tanker stocks' elasticity is more independent and more direct than upstream oil & gas (中远海能 H1 net profit to parent +143%, 招商轮船 +228% already realized in earnings); ② but the stocks' 3-year percentiles are already 91%/99%, H1 results correspond to "already-realized rates", and Q3 increment depends on whether rates jump a second time since September — real-time VLCC TCE is unavailable locally and is marked "to be verified" in this report; readers should check Baltic/Clarksons quotes before the open; ③ weekend news is two-way: Trump's rejection (bullish oil) vs the China-US "no tolls on international waterways" + Axios's Monday-talks claim (cooling). The calmer the situation across the strait, the thinner this branch's premium; today is the touchstone.

(3) Memory: the hardest fundamentals in the market, but watch for "pre-earnings profit-taking" before the holiday. DRAM contract prices Q1 +9095%, Q2 +5863%, Q3 expected +30% — delivered consecutively on TrendForce's measure; Micron's 9/30 earnings (US Eastern) fall inside the A-share long holiday: holding through it = holding the earnings reaction blind. Today through Wednesday is the last rebalancing window for funds that "want memory exposure but fear the earnings" — expect amplified volatility. 兆易创新: H1 net profit to parent +1091%, PE-TTM 33.5x — the highest earnings-realization name among A-share memory designers; 佰维存储: H1 net profit to parent +3274% but operating cash flow -RMB 6.2 billion and liability ratio 61.6% — "low-cost inventory revaluation" profits that bite back the moment the cycle turns. Within the branch, choose "design", drop "module revaluation".

(4) Robots: media-level evidence — trade it with B-grade discipline. The "Tesla audit with 5,000-unit initial order" comes from media / supply-chain rumor; no A-share company announcement confirms any supply relationship; the "Optimus output ×10" phrasing is "up from an extremely low base" (a few hundred units per week). One counter-signal that must be recorded: Tesla closed -1.54% on Friday in the US — the Optimus output news won no buyers in its home market; A-share enthusiasm needs faster confirmation to hold. On 9/24 funds already bought robot actuators / reducers into the top two net-inflow slots; adding more today is a second relay. Carrying forward the evidence grading from the 09-18 report: 三花智控 / 拓普集团 are "Tesla auto-chain real, robot-chain unconfirmed", 均胜电子 is "the most concentrated rumor — but still a rumor" — all handled as second-tier, no S/A grade.

(5) The media high-flyer cluster: the biggest ebb-risk source today. 5-board Xinhua Winshare (9/17–9/24 cumulative +68.88%; company attests fundamentals unchanged + received regulatory work letter), 4-board Xinhua Media (planning to acquire Jiemian CLS; company's 9/25–26 announcement flagged the audit/appraisal as incomplete and uncertain), 6-boards-in-7-days Inner Mongolia Xinhua — the ladder has a gap at 3 boards; the highs rest entirely on sentiment. If the cluster cannot gap up strongly together in the auction today, ebb is confirmed; not a recommended direction — observe it only as a sentiment weathervane.

(6) Defense: 9/24's haven, durability in question. Defense +RMB 884 million / defense electronics +RMB 750 million / large aircraft +RMB 1.047 billion were 9/24's only inflow directions, but the leaders — 雷科防务 (H1 loss, TTM loss) and 霍莱沃 (20cm) — are small-cap sentiment plays; 光启技术, which has real orders (RMB 907 million contract), actually fell -6.02% on 9/24. This branch today is the key test of whether funds are really rotating: watch whether the core large-caps with orders (光启技术 / 菲利华-type) repair on volume, not whether small caps string together limit-ups.

3. Stock bullish-strength master list (sorted by total score, descending)

Scoring model in §4. "Verdict" labels: priority deep-dive / watch closely / watch only / Pass. Quotes are as of the 9/24 close.

Weathervanes to watch today beyond the master list (not recommendations): 内蒙新华 (603230) / 新华文轩 (601811) / 新华传媒 (600825) — the media high-flyer cluster, watch whether they ebb; 雷科防务 (002413) — defense sentiment marker; 奥佳华 (002614) / 泰慕士 (001234) — robot / textile 4-board high-flyers; 平潭发展 (000592) — "map speculation" sentiment marker.

---

4. Stock scoring model (total 100, sub-items below)

Model: source authority 0–15｜directness of benefit 0–20｜earnings elasticity 0–15｜industry position & fundamentals 0–15 (SEPA lens: revenue / net profit / gross margin / cash flow / liability ratio / moat / niche leadership)｜expectation gap 0–10｜theme durability 0–10｜A-share trading attributes 0–10 (liquidity / recognizability / board price-limit band)｜risk deduction 0 to -15.

Deduction logic: ① the two tanker heroes are deducted for "3-year price percentiles 91%/99%" + unverified real-time rates; ② the memory chain uniformly deducted for "Micron earnings inside the long holiday — blind-holding risk"; ③ the robot family uniformly deducted for "supply relationships are media-level evidence with no announcement"; ④ Kuang-Chi deducted for "old news outside the window + 86x PE + the market already voted -6%"; ⑤ Kangqiang Electronics has low directness and low elasticity but a small risk deduction — because its problem is not "having risk" but "having no logic"; its total naturally sits at the bottom.

5. Top 10 detailed stock analysis

1中远海能600026Branch: oil tankers | Tag: priority deep-dive · COSCO Shipping Energy · main board

• Related news: 9/25 WSJ reported Trump rejected Iran's "reopen Hormuz in 7 days" proposal; 9/27 Axios said US-Iran could resume talks as early as Monday; point three of the China-US consensus, "no tolls on international waterways" (CLS⁴、MFA¹).
• Bullish logic: Hormuz transit volumes -77% vs pre-war; disrupted transport without production cuts; longer VLCC hauls + war-risk premium + ship-scramble sentiment push TCE up directly — it acts on freight rates, not oil prices; high oil prices themselves bite demand (Brent USD 106.3 this morning, WTI USD 93.55), but the rate elasticity was already realized in H1 results (gross margin 41.4% vs only 26.1% for all of FY25).
• Branch stage: oil tankers are the branch that realized earliest and rose the most in this crisis (Haineng +32.8% over 60 days), in a "high-position disagreement phase after the climax", not an ignition phase.
• Fundamental verification (akshare / 10jqka caliber, 2026H1): revenue RMB 15.146 billion +30.0%; net profit to parent RMB 4.545 billion +143.2% (already above FY25 full-year RMB 4.037 billion); operating cash flow ≈RMB 6.95 billion (net-cash ratio ≈1.5); liability ratio 49.1%; 2026 interim dividend 2.80 yuan per 10 shares. PE-TTM 16.9x, PB 2.43x.
• Industry position: one of the world's largest tanker fleets with VLCCs at the core — niche leader.
• Technicals & sentiment: closed +1.52% on 9/24 when the broad market was -1.22% — textbook resilience against the tape; the 3-year price percentile of 91.4% says chips sit at highs. Main board ±10%.
• Final call: the name with the best "event hardness × earnings realization" fit in this entire report. If oil gaps up today but the stock gaps up less than 3%, funds are taking profits rather than adding; a volume breakout would signal branch continuation. The biggest variable is real-time freight rates (local VLCC TCE unavailable — verify before the open).

2兆易创新603986Branch: memory | Tag: priority deep-dive · GigaDevice · main board

• Related news: US memory stocks broadly up Friday (Qualcomm +4% / SK Hynix +2%); Solidigm rumored USD 150 billion IPO; Micron 9/30 earnings; ITC Section 337 investigation on DRAM equipment (CLS²、CLS morning report⁴).
• Bullish logic: memory is an AI-driven price-hike supercycle (TrendForce: Q1 DRAM contract +9095%, Q2 +5863%, Q3 expected +30%); GigaDevice's NOR / niche DRAM / MCU all benefit, and the gross-margin inflection from 40.2% to 63.1% was confirmed in H1 — it acts directly on the financial statements, not on sentiment.
• Branch stage: the A-share memory chain is down -44% to -50% over 60 days, in a divergence zone of "hardest fundamentals, weakest stock prices", awaiting a catalyst for re-pricing; the US Solidigm IPO rumor + Micron earnings are the triggers.
• Fundamental verification (2026H1): revenue RMB 11.566 billion +178.7%; net profit to parent RMB 6.857 billion +1091.5%; gross margin 63.1%; ROE (half-year) 23.1%; liability ratio 11.5% (near net cash); OCF ≈RMB 6.03 billion. PE-TTM 33.5x, PB 7.2x.
• Industry position: top-3 global NOR Flash, domestic leader in niche DRAM and MCU — niche leader.
• Technicals & sentiment: 9/24 -3.75% on shrinking volume, no breakdown; 60-day -44.8% oversold. Main board ±10%.
• Final call: the best "earnings elasticity / valuation" ratio among the 13 verified names (33.5x against +1091% profit). Two risks: the cyclical "low-PE illusion at the top" (33x is not low for a cyclical), and Micron earnings falling inside the long holiday. Today through Wednesday is the rebalancing window — suitable for buying dips, not for chasing.

3中际旭创300308Branch: optical modules / compute | Tag: priority deep-dive · Zhongji Innolight · ChiNext ±20%

• Related news: Goldman expects 2027 cloud AI capex of USD 1.2 trillion (+50%); the Anthropic–Akamai USD 11.6 billion compute contract; the company announced on 9/24 the completion of the RMB 5 billion buyback (CLS²).
• Bullish logic: cloud capex is the direct leading indicator for optical-module shipments; in the 1.6T ramp the company's results are already verified (H1 net profit to parent +241.7%). CPO is a far-term variable after 2028 — a narrative, not a threat, in the short run. The RMB 5 billion buyback (≈0.5% of market cap) and its executed price range imply the company's own view of an undervaluation zone.
• Branch stage: optical modules were the hardest-hit area of September's main-line ebb (9/18 electronics +RMB 38 billion → 9/24 electronics -RMB 22.876 billion), now in a "first-wave repair observation phase after the ebb"; as the leader, Innolight has more repair elasticity than the back row.
• Fundamental verification (2026H1): revenue RMB 41.778 billion +182.5%; net profit to parent RMB 13.651 billion +241.7%; gross margin 46.3%; ROE (half-year) 37.6%; liability ratio 36.1%. Flaw: H1 operating cash flow only ≈RMB 1.79 billion (net-cash ratio 0.13; FY25 OCF per share 9.81 yuan) — inventory/receivables ballooned; earnings quality needs watching. PE-TTM 48.5x, PB 25.1x, market cap ≈RMB 994.4 billion.
• Industry position: global optical-module leader (core large-cap).
• Technicals & sentiment: 9/24 -2.89%, clearly resilient vs components (-4.34%) / PCB (-4.74%); 60-day -21.6%. ChiNext ±20% — high volatility elasticity.
• Final call: top-tier earnings realization market-wide, PEG<0.6. If the electronics chain repairs today, it is institutions' first buy-back target; if it gaps up more than 5% without volume expansion, treat as an "ebb continuation" and do not chase.

4招商轮船601872Branch: oil tankers | Tag: watch closely · China Merchants Energy Shipping · main board

• Related news / bullish logic: same as COSCO Shipping Energy. Additional variable: the world's largest VLOC fleet; dry bulk is a second-order driver of the "iron ore–China" route cycle; H1 net profit to parent +227.6% (RMB 6.960 billion, above FY25 full-year RMB 6.012 billion).
• Fundamental verification (2026H1): revenue RMB 19.651 billion +56.2%; gross margin 45.0%; ROE (half-year) 15.61%; OCF ≈RMB 8.17 billion; liability ratio 47.5%. Flaw: the 2026 interim payout ratio was only 15.1% (payout cut even as profit surged, retaining for expansion) — a minus for dividend-style funds. PE-TTM 15.6x, PB 3.61x, market cap ≈RMB 169.3 billion.
• Technicals & sentiment: 9/24 +0.72% resilient; 3-year price percentile 99.0%, the highest of the 13 — elasticity is essentially fully priced.
• Final call: pick one of the two tanker names — for pure elasticity choose Haineng (percentile 91% vs CMES's 99%); for an "oil + dry bulk" double hedge choose CMES. The biggest risk is double cycle-top resonance: no averaging down on this one — trade it as a T.

5均胜电子600699Branch: robots | Tag: watch closely · Joyson Electronics · main board

• Related news: rumor of Tesla's Yangtze Delta audits carrying an initial order of 5,000 units; attention on electromechanical parts such as joint modules; Bloomberg et al. report Optimus output ×10 (a few hundred units per week) (Sina⁶、CLS²).
• Bullish logic: rumor-level — neither the audit nor the order is confirmed by any company announcement or by Tesla; graded as an "industry-trend positive" rather than a "direct order positive". The company's logic is identity-positioning as an "old auto-electronics supplier → robot electromechanical actuators".
• Branch stage: robots became funds' new direction on 9/24 (actuators +RMB 1.041 billion / reducers +RMB 638 million net inflow); Joyson's 9/24 limit-up = ignition first board; the sector's high-flyer 奥佳华 (002614) is at 4 boards. Ignition phase; the ladder is not yet formed.
• Fundamental verification (akshare / 10jqka caliber, 2026H1): revenue RMB 28.091 billion -7.4%; net profit to parent RMB 739 million +4.4%; ex-non-recurring RMB 655 million; gross margin 17.7%; liability ratio 67.0% (high leverage left by historical M&A in auto safety). TTM PE ≈24x. Revenue has shrunk for two consecutive quarters — the core business is contracting; the valuation rests entirely on the robot option.
• Industry position: global top player in auto electronics + auto safety (core large-cap identity, not an elastic small cap).
• Technicals & sentiment: 9/24 A-share limit-up close at 23.68 yuan (+9.99%), H-share +10.98% in lockstep (00699.HK) — A/H resonance is a plus; market cap ≈RMB 33.3 billion. Main board ±10%.
• Final call: today's trading-recognizability name in the robot branch. Verification points: whether Tesla officially announces the audit/order and whether the company responds on the investor-interaction platform; if it is only a sentiment pulse, 24x PE + negative revenue growth cannot support consecutive surges. Manage the position as an "option".

6中海油服COSL / 601808Branch: oil services | Tag: watch closely · main board

• Related news: on 9/23 controlling shareholder CNOOC Group made its first A-share purchase of 0.41 million shares (≈RMB 4.98 million), planning RMB 300–500 million cumulative before 2027-04-08 (disclosed 2025-04, extended one year); oil oscillated at highs during the holiday.
• Bullish logic: indirect transmission — high oil prices → offshore oil & gas capex and day-rate upgrades. Note H1 net profit to parent was only +2.3%: day-rate elasticity has not yet been realized; the share purchase is a "signal", not "earnings".
• Fundamental verification (2026H1; code corrected to 601808): revenue RMB 23.787 billion +2.0%; net profit to parent RMB 2.009 billion +2.3%; gross margin 18.5%; liability ratio 42.98%; H1 operating cash flow turned negative at -RMB 1.43 billion (FY25 full-year OCF ≈RMB 11.3 billion — possibly payment timing; watch the interim-report structure). PE-TTM 14.9x, PB 1.22x, market cap ≈RMB 57.8 billion. 3-year price percentile only 4.7% (3-year range 10.79–20.68 yuan) — the only one of the 13 sitting at a historical low.
• Technicals & sentiment: 9/24 closed flat (12.12 yuan), no panic; the low position = a thick cushion.
• Final call: a "low valuation + shareholder-purchase backstop" type, not an earnings-driven type. Suitable as a low-position catch-up watch alongside oil tankers; if the two tanker leaders gap up too much, funds may spill into it. Risk: negative cash flow + unrealized day rates = continued bottom-grinding.

7佰维存储688525Branch: memory | Tag: watch only · BIWIN Storage · STAR Market ±20%

• Related news: same as GigaDevice; in addition — if the ITC 337 investigation targets Korean equipment, sentiment for the domestic memory chain strengthens again.
• Bullish logic: module makers earn "low-cost inventory revaluation" money in a price-hike cycle: gross margin 21.4% → 54.8%, H1 net profit to parent +3273.5% — more violent elasticity than designers, but the profit's "inventory-price content" is also higher.
• Fundamental verification (2026H1): revenue RMB 15.575 billion +298.1%; net profit to parent RMB 7.166 billion +3273.5%; ROE (half-year) 78.7%; but operating cash flow -RMB 6.24 billion (massive stocking) and liability ratio 61.6% — the most fragile balance sheet of the 13. PE-TTM 11.9x, PB 7.8x.
• Technicals & sentiment: 9/24 -5.24%, weaker than GigaDevice; 60-day -49.6%. STAR Market ±20% — extreme volatility.
• Final call: the textbook sample of a "cyclical illusion" — the low 11.9x PE annualizes a single quarter at the cycle peak; once contract prices turn, inventory impairment + high leverage strike together. Watch it as a memory-sentiment thermometer, not as a memory position.

8光启技术002625Branch: defense metamaterials | Tag: watch only · Kuang-Chi Technologies · main board

• Related news: old news outside the window (announced 9/17 19:06): subsidiary Kuang-Chi Front-end signed metamaterial batch-production contracts totaling RMB 907 million with three customers (single customer RMB 862 million), ≈80% of H1 revenue (CLS¹²). Why it is effective today: the defense branch became a capital haven on 9/24, and the market may re-price its orders.
• Bullish logic: defense orders are a direct positive with high truthfulness (announcement-level); but over the five trading days from 9/18 to 9/24 the market expressed its "one-off mega-order vs 86x PE" hesitation with a -6% move.
• Fundamental verification (2026H1): revenue RMB 1.128 billion +19.6%; net profit to parent RMB 319 million -17.4%; gross margin 50.1%; OCF ≈RMB 170 million (well below net profit); liability ratio 17.5%. PE-TTM 86.1x, PB 5.5x, market cap ≈RMB 53.2 billion; 3-year percentile 33.4% (-43% year-to-date).
• Industry position: absolute metamaterials leader with a real moat (patents + military qualifications).
• Technicals & sentiment: 9/24 -6.02%, weaker than the defense sector — strong branch, weak stock: funds did not pick it as the flag-bearer; year-to-date orders are nearing RMB 1.8 billion (9fzt¹³).
• Final call: the orders are real, the valuation is expensive, the market is cold. Follow only if core large-caps repair on volume; do not proactively recommend; if defense strengthens today while it stays weak, funds still don't believe — remove it from the watch pool.

9拓普集团601689Branch: robots | Tag: watch closely · Tuopu Group · main board

• Related news: same as Joyson Electronics (Optimus output ×10 + audits); the company itself has no robot-business announcement.
• Bullish logic: a platformized Tesla supplier (interior / chassis / thermal management); robot actuators are its strongest far-term option; carrying forward the 09-18 report's conclusion: the auto-chain relationship is real, but the robot-chain supply relationship has no announcement-level verification.
• Fundamental verification (2026H1): revenue RMB 14.199 billion +9.8%; net profit to parent RMB 1.023 billion -21.0%; gross margin 18.8%; OCF RMB 2.58 billion > net profit (decent quality); liability ratio 43.1%. PE-TTM 32.0x.
• Technicals & sentiment: 3-year price percentile only 15.2% — the most fully corrected name in the robot core chain; 9/24 +1.20% resilient.
• Final call: pick one vs Joyson: for recognizability choose Joyson (rumor concentration + A/H resonance); for position choose Tuopu (percentile 15%). The -21% core-business profit is a hard flaw; if robots don't materialize it is just a 32x auto-parts stock.

10亨通光电600487Branch: optical comms / CPO | Tag: watch only · Hengtong Optic-Electric · main board

• Related news: 9/25–26 announcement of a planned private placement of up to RMB 6.636 billion into CPO, AI optical interconnect and other projects (Sina announcement roundup⁷).
• Bullish logic: the placement's use of proceeds is a "valuation narrative" — CPO has weak synergy with the submarine-cable / fiber core business; RMB 6.6 billion ≈ 4% market-cap dilution; the base remains submarine cables (offshore wind) and optical comms; order value not verified in this report.
• Fundamental verification (2026H1): revenue RMB 42.026 billion +31.1%; net profit to parent RMB 3.120 billion +93.4%; gross margin only 16.8%; OCF ≈-RMB 850 million; liability ratio 52.4%. PE-TTM 38.9x, PB 4.9x; 3-year percentile 91.6%.
• Technicals & sentiment: 9/24 -3.66%, 60-day -28.2% — trend still down.
• Final call: the announcement is real but does not constitute a reason to buy today; wait for hard evidence on one of the three — the placement's final price, CPO customer validation, submarine-cable orders.

7. Intra-branch ranking

(A) Oil tankers / oil & gas (the strongest event branch of the holiday)

Follower judgment: 招商南油 (China Merchants Nanjing Tanker, 601975, product tankers) has the next-best elasticity; who gets a Pass: upstream oil & gas producers (the logic is disrupted transport without production cuts — the production story is in Saudi Arabia, not in A-shares).

(B) Memory (the hardest-fundamentals branch)

(C) Robots (Tesla chain)

(D) Defense / satellite internet (9/24's haven)

(E) Optical modules / compute (repair, not a new cycle)

8. Tomorrow's (today's post-open) validation signals

Auction signals (9:15–9:25)

• Gap-up size in the call auction: Shanghai Composite gapping up 0.5% or more = the consensus repair is endorsed; <0.2% = the positives are drowned by pre-holiday profit-taking
• Media high-flyers (Xinhua Winshare / Xinhua Media / Inner Mongolia Xinhua): whether they gap up strongly together — a weak or flat open = ebb confirmed, the day's sentiment ceiling locked; gap-up with instant limit-up = sentiment repair beyond expectations
• The two tanker leaders' (COSCO Shipping Energy / China Merchants Energy Shipping) gap size and auction volume: gap up >3% with enlarged auction turnover = funds choose the event branch; gap up then fade = weekend news offset by "Monday talks" expectations
• One-word boards / overnight orders: watch for new holiday-news one-word boards (glass substrates / memory direction)

Sector signals (9:30–10:30)

• Whether the export chain (textiles / home appliances / cross-border e-commerce) gets 3 or more rapid limit-ups — the measuring stick for China-US-consensus beta; Taimus (001234) attempting a 5th board from 4 is the key watch
• Memory chain: GigaDevice recovering the 9/24 drop on volume = supercycle re-pricing begins; modules (BIWIN) up while design not = sentiment, not allocation
• Robots: whether Joyson Electronics gets a second consecutive board + Tuopu follows = branch promotion; only OGAWA dancing alone at highs = ebb
• Electronics chain (components / PCB): if net outflow continues >RMB 10 billion, the quality of the index repair is in doubt
• Volume: if half-hour turnover is significantly below the same period on 9/24 (pre-holiday effect), the bounce height is limited; full-day combined turnover estimated <RMB 1.5 trillion = shrinking-volume bounce — do not chase

Single-stock signals

• Zhongji Innolight: gap up 2–5% + volume = institutional buy-back; gap up >5% without volume = profit-taking supply
• COSCO Shipping Energy: holding above the open for 30 minutes = strength; breaking below with oil falling in tandem = the event branch yields
• Kuang-Chi Technologies: defense sector up while it does not move = remove from the watch pool

Risk signals (cut exposure on sight)

• Gap-up dive: Shanghai Composite gaps up 0.5%+ but turns red within 30 minutes — the classic pre-holiday profit-taking pattern
• Lone limit-up: only one limit-up in tankers / memory with no followers
• Core large-caps not following: theme small caps rush while COSCO Shipping Energy / GigaDevice / Innolight do not
• Weak index: Shanghai Composite breaks below the 9/24 low around 3850 (intraday support references 3874/3860)
• Yesterday's strong theme ebbs: media high-flyers limit-down together, crushing short-term sentiment
• Overseas-market disturbance: if the US and Iran officially announce Monday talks during the day, or the situation escalates in reverse, oil price jumps will transmit in real time

9. Final recommendations

① Today's 5 most noteworthy stocks

② Today's 3 strongest branches

③ Directions not to chase today

• The publishing & media high-flyer cluster (Inner Mongolia Xinhua / Xinhua Winshare / Xinhua Media): regulatory work letter + company attesting unchanged fundamentals + a gap in the ladder — ebb more likely than persistence
• Glass-substrate back row: the Nvidia story is real but lands only in 2028; WoGe Optoelectronics is loss-making with PB 21.6x — a pure sentiment pulse
• Silver stocks: the vehicle flaws are unsolved (halted production / investigation / cost inversion, carrying forward 09-18); even if silver rises, it won't be their clean benefit
• Chasing a gold-stock bounce: with hike probability at 69.7%, haven buying cannot beat rising real rates
• PCB / components back row: five sessions of systematic trimming with no shrinking-volume stabilization signal — in a repair, watch the leaders first

④ Final one-line judgment

Today is a repair window with a triple overlay of "macro positives × sentiment ice point × three pre-holiday days": the gap-up will come; sustainability depends on volume — export-chain beta and the oversold repair of tankers, memory, and optical-module leaders are tradable, but manage positions for "three pre-holiday days"; more money will take profits into the gap-up than will chase it — don't be the bag holder.

A-share volatility risk is extremely high; automatically generated content may contain information timeliness gaps or industry-chain mapping errors, and must not be used directly as a trading basis. Price-limit bands differ across stocks in this report (main board ±10% / ChiNext · STAR Market ±20% / Beijing Stock Exchange ±30%); please judge limit-ups and risks against each board's actual band. Pre-holiday liquidity and overseas events (US-Iran talks, Micron earnings, US Treasury yields) can all invalidate this report's judgments quickly.
