〔Overnight Brief〕Long-End UST Pressure Caps Risk Appetite Even as NVIDIA Data-Center Doubles to $89B, HK Long-Term Foreign Capital Nears HKD 100B Since June, BSE Posts 83% Profit Coverage - Beta to Earnings

0. Weekly Arc

The consensus week: AI capex printed, A-shares shrugged. NVIDIA's data-center line hit $89B (+18% q/q, +100% y/y) with FY2028 modeled at +70% ^[1], yet BoC Securities still names U.S. Treasury supply as the single largest external risk for A-shares — Bessent is doubling long-end buybacks just to contain yields, and Warsh (沃什) struck a hawkish tone at Jackson Hole ^[2]. Hong Kong is the relative bright spot: long-term foreign capital has returned nearly HKD 100B since end-June, with last week alone showing HKD 14.0B stable and HKD 27.0B flexible inflows against HKD 23.1B of Stock Connect outflows ^[3]. The market is in transition: broad beta has given way to structural earnings plays ^[2][4][5].

1. Policy and Cross-Asset Backdrop

• **[ESCALATED] U.S. Treasury supply — BoC Securities ^[2]:** Bessent announced he will at least double the long-end Treasury buyback scale; multi-factor supply pressure (Treasury issuance + AI hyperscaler financing demand) and weaker demand are pushing long yields higher ^[2]. Warsh (沃什) delivered a hawkish Jackson Hole signal, but BoC reads the September hike as conditional on inflation data and constrained by the pre-midterm political window ^[2].
• **[ONGOING] CITIC read ^[4]:** the Fed is "cautiously hawkish," restating that the 2% inflation target is unshakeable — a short-term risk-asset headwind, though if it stabilizes long-end rates and flattens the curve it removes the tail risk of further financial-conditions tightening ^[4].

2. AI and Capex

• **[NEW] NVIDIA Q2 FY2027 ^[1]:** revenue $96B (+100% y/y), data-center $89B (+18% q/q), hyperscale $49B (+13% q/q), ACIE $40B (+25% q/q, +138% y/y), Q3 guide $108B ±2%, FY2028 modeled +70% y/y ^[1]. Guojin reads NVIDIA's reported acquisition of Hugging Face as compute vendors reaching into the open-source model layer and platform entry point ^[1].
• **[NEW] Domestic open-source push ^[1]:** Tencent released Hunyuan Hy4preview (770B total params, 1M context), placing it in the top open-source tier on engineering tasks; Zhipu's GLM-5.3-Flash added native multimodal and Coding capability at low API pricing on domestic compute ^[1]. Google's Gemini Omni1.1Flash moved video generation to 4K ^[1].
• **[NEW] Domestic test-equipment build-out ^[6]:** a research note highlights a DRAM test-equipment vendor with full-process coverage, tight collaboration with ChangXin Memory (长鑫存储), and extension into NAND Flash, SoC testers, advanced packaging sorters and probe stations ^[6].

3. China A-Shares and Hong Kong Flows

• **[NEW] Hong Kong ^[3]:** since end-June, long-term foreign capital has returned nearly HKD 100B to HK; last week (8/19–8/25) total inflows reached HKD 14.2B — stable foreign +HKD 14.0B, flexible foreign +HKD 27.0B, Stock Connect -HKD 23.1B ^[3]. Guosen flags a structural bid, with the tradeable question being whether the Stock Connect drag deepens ^[3].
• **[NEW] Northbound A-shares ^[3]:** estimated net outflow RMB 2.4B in 8/24–8/28 (prior week -RMB 1.2B); flexible foreign a marginal +RMB 50M inflow ^[3]. Most active: Innolight (中际旭创, RMB 27.5B two-way turnover, 11% of weekly stock turnover), CATL (宁德时代, RMB 16.2B, 19%), Eoptolink (新易盛, RMB 15.9B, 10%) ^[3].
• **[ONGOING] Strategy reset ^[2][4][5]:** BoC, CITIC, and the sector-rotation desk converge — broad beta is over, earnings verification is the new alpha ^[2][4][5]. CITIC leans "rebalancing" with a defensive floor plus cyclical laggards ^[4]; the September rotation report prefers a barbell of large-cap value and small-cap growth, with dividend-quality (medicine, non-ferrous, consumer, non-bank financials) plus cyclical bottom-fishing (agriculture, chemicals on El Niño, real-estate chain) ^[5]. CITIC also flags AI computing, non-ferrous, innovative drugs, banks, non-bank financials, oil, coal, steel, agriculture ^[4].

4. Beijing Stock Exchange and Structural Themes

• **[NEW] BSE 50 weekly ^[7]:** closed 8/28 at 1063.80, -1.08% w/w; 339 constituent stocks, avg market cap RMB 2.48B; weekly turnover RMB 84.773B, -46.26% w/w; avg daily turnover ratio 3.60%, -0.73 ppt w/w ^[7]. Li Chao (李超), Deputy Director of the NDRC Policy Research Office, said China's integrated-circuit exports reached RMB 1.49T in the first 7 months, +91.6% y/y ^[7].
• **[NEW] BSE H1 2026 aggregate ^[8]:** total revenue RMB 138.566B (+15.11% y/y), avg RMB 409M; total net profit RMB 11.783B (+17.58%), avg RMB 34.76M; 70.80% (240 firms) revenue growth, 47.49% (161 firms) net-profit growth, 83.19% (282 firms) profitable; 25 firms with net profit >RMB 100M, 15 turned around; contract liabilities RMB 13.800B (+34.53%) — order book supportive for H2 ^[8]. Sector breakdown by revenue growth: chemical new materials +23.34%, IT +19.00%, high-end equipment +13.97%, consumer services +5.64%, pharma +5.26%; only IT, chemical new materials and consumer services achieved net-profit growth ^[8].
• **[NEW] BSE IPO pipeline ^[9]:** Zhuomu Technology (卓目科技), an edge-AI specialist serving high-resolution earth observation, manned spaceflight and lunar exploration, was accepted by the BSE in H1 2026; the 102-firm H1 2026 BSE-accepted cohort shows median 2025 revenue RMB 598M, median net profit RMB 77.7M, median net margin 12.5%, median revenue growth 14.3%, median R&D intensity 4.1% ^[9]. NEEQ has cumulatively delivered 919 listed companies to Shanghai/Shenzhen/Beijing/HKEX as of 8/28/2026 ^[9].

5. Contrarian and Tail Risks

• **[NEW] Australia rate-cycle skepticism ^[10]:** Bloomberg reports top Australian-dollar forecasters see the two-month rally nearing a peak and warn that RBA rate-hike bets have gone too far — a contrarian signal against the global "higher-for-longer" narrative ^[10].
• **[NEW] Structural labor-share warning ^[11]:** the "投石问K" series documents a winner-takes-all pattern across major industrial economies — top 10% of Chinese listed manufacturers hold >90% of profits but only ~50% of employment, with the gap widening in upgrading-stage manufacturing and narrowing in mature manufacturing ^[11]. Implication: AI-led productivity gains may deepen the asymmetry and constrain the consumption multiplier ^[11].
• **Source quality control:** the BSE H1 aggregate numbers and HK flow data are well-sourced ^[3][8]; the AUD contrarian call is single-source via Bloomberg ^[10]; the U.S. Treasury supply narrative is a single-house view (BoC Securities) that CITIC partly qualifies with a curve-flattening offset ^[2][4].
