Q3 2026

AI Data-Center Demand Lifted Dongshan; US Content Rule and Tax Clouded Q3

  • AI data-center demand and profit surge Suzhou Dongshan Precision's first-half net profit jumped 290% to 2.957 billion yuan, powered by AI data-center demand. Its 1.6T optical modules were already shipping, showing the company is a real supplier to the AI buildout.

    This is the core positive force behind the stock's strong quarter.

  • Fund manager buying and rising PCB material prices Top fund manager Zhang Kun added the stock to his top ten holdings, a strong vote of confidence. At the same time, rising prices for PCB materials lifted the whole sector, helping Dongshan's shares.

    These are new positive catalysts that supported the stock during the quarter.

  • US optical-module content rule and China VOCs tax A US plan requiring 65% domestic content in optical modules hit the stock, which fell by its daily limit. Dongshan denied the rumor, but China's new VOCs environmental tax from 2027 also raised compliance-cost concerns.

    These regulatory risks were major negative forces that weighed on the stock.

  • AI-spending doubts and sharp CPO/PCB swings OpenAI's weaker revenue forecast fueled doubts about AI spending, and sharp swings in CPO and PCB shares added volatility. These moves reflected shifting sentiment rather than Dongshan's own fundamentals.

    This explains the negative sentiment and volatility that partly offset the strong quarter.

AI demand lifts Dongshan, but US optical-module rules and AI-spending doubts hit

  • AI-driven PCB demand and rising material prices lift Dongshan Electronic fabric prices jumped 17-18% in August, their biggest monthly gain this year, pushing up PCB material costs. Dongshan, a PCB maker, benefits as AI servers and chips drive demand for its boards, and the whole PCB sector rallied with it.

    This explains the core demand and pricing force pushing Dongshan's shares up.

  • First-half profit up 290% and 1.6T optical modules already shipping Dongshan reported first-half net profit of 2.957 billion yuan, up 290% from a year earlier. It also said its 1.6T optical modules are already being supplied to customers, showing it is winning business in the fast-growing AI data-center market.

    Strong earnings and new high-end product shipments are direct positive drivers for the stock.

  • US plan to limit Chinese optical modules hits the stock A Morgan Stanley report said the US may require 65% of optical-module parts to come from US suppliers, starting with next-generation 3.2T products. Dongshan and other optical stocks fell sharply, with Dongshan hitting its 10% daily limit down, as investors feared lost overseas sales.

    This is the main new risk weighing on Dongshan's price this period.

  • Dongshan denies rumor, but AI-spending worries drag sector Dongshan denied the 65% US-content rumor, saying some optical chips are self-developed and make up under 10% of material costs. Still, the stock and the whole AI hardware sector fell after OpenAI's revenue forecast came in about $20 billion below expectations, raising doubts about AI spending.

    Shows the company's pushback against the rule, but also the broader AI-demand worry that hurt the stock.

Earnings Surge and Fund Buying Offset Tax and Selloff Shocks

  • First-half profit forecast up 283–296% on AI data center demand DSBJ expects H1 2026 net profit of 2.9–3.0 billion yuan, up 283–296% year on year. The jump comes from data center investments, its optical module business integration, and solid consumer electronics and auto parts. This directly boosts earnings expectations and supports a higher stock price.

    The profit surge is the core fundamental driver behind the stock's re-rating.

  • Zhang Kun adds DSBJ to top ten holdings for first time Top fund manager Zhang Kun added Dongshan Precision to his fund's top ten holdings in Q2, shifting away from baijiu toward tech growth. This signals rising institutional demand and can attract more buyers, pushing the price up.

    Institutional buying is a direct demand catalyst for the shares.

  • New environmental tax on VOCs to raise compliance costs from 2027 China will pilot an environmental protection tax on volatile organic compounds across eight industries, including general equipment manufacturing, starting January 1, 2027. DSBJ fell 9.74% on the news as investors worry about higher compliance costs and tighter regulation.

    This is a new regulatory cost that could pressure future margins.

  • CPO sector selloff and PCB rebound show high volatility On July 17, CPO concept stocks plunged and DSBJ hit the daily limit down amid a broad tech selloff. By July 27, the PCB sector rallied and DSBJ rebounded 6.39%. These sharp swings reflect sector-wide sentiment, not company-specific news, and add short-term trading risk.

    The extreme price swings show how sector sentiment can overwhelm fundamentals in the short run.

AI demand lifts Delta, but bond overhang and rotation cap gains

  • AI data-center demand and product ramp Analysts raised 2027 AI spending forecasts, and Delta is ramping its 800-volt power system for NVIDIA's Vera Rubin, positioning it to capture more of the AI infrastructure buildout.

    This is the main growth driver behind Delta's business and stock appeal.

  • Easing shortages and peak Q3 profit Component shortages are easing, and Q3 profit is expected to peak, which supports earnings momentum and gives investors confidence in near-term results.

    It explains the improved operational backdrop and profit outlook.

  • Broker upgrades and improved sentiment Krungsri upgraded the sector and named Delta a top pick, while Bualuang kept a 330 baht target. US-China AI talks and an extended trade truce also lifted sentiment.

    These events boosted investor confidence and buying interest.

  • Exchangeable bond overhang and sector rotation A $1.5 billion exchangeable bond creates a share overhang, capping the stock, which fell 6% on the news. Investors also rotated into KCE and HANA, limiting Delta's rebound.

    This is the main counterweight that held back the stock despite positive drivers.

Delta's AI power and cooling orders strengthen as trade tensions ease

  • US-China AI talks and extended trade truce lift sentiment Trump and Xi held their first talks on AI and extended the trade truce to January 2027. Less chip and trade tension is good for Delta, because its AI data-center power and cooling gear sells into a global build-out that depends on open trade.

    New geopolitical de-escalation directly improves the outlook for Delta's AI-linked demand.

  • AI racks need far more power, raising Delta's content per rack Morgan Stanley raised its power estimate for NVIDIA's next racks, and Bualuang kept a 330 baht target, seeing Q3 sales up 34% year on year. More power and cooling per rack means Delta sells more valuable equipment in each AI data center.

    This is the core demand driver behind Delta's earnings growth and stock price.

  • Delta launches 800 VDC AI data-center system for NVIDIA Vera Rubin Delta unveiled a modular AI data center with 800-volt in-row power and liquid cooling built for NVIDIA's Vera Rubin. Winning a place in the next-generation AI architecture supports future orders and shows Delta's technology is central to the build-out.

    A concrete new product tied to NVIDIA's roadmap strengthens Delta's competitive position.

  • Brokers turn more bullish, naming Delta a top pick Krungsri upgraded electronics to Bullish and picked Delta with a 320 baht target, expecting 51% profit growth in FY27. Kasikorn also named Delta a stock to accumulate on market dips, citing strong AI demand and recovering margins.

    Upgraded recommendations and higher targets can pull investor money back into the stock.

Delta's AI power demand stays strong, but bond overhang and rotation cap the stock

  • AI data-center demand keeps building Delta is ramping raw materials for its new 800-volt AI data-center power system, and analysts say big tech's 2027 AI spending plans are being revised sharply higher. More AI factories mean more orders for Delta's power gear, supporting revenue and prices.

    This is the core growth engine behind Delta's earnings and the main reason analysts stay positive.

  • Supply shortages ease, profit seen peaking in Q3 The component shortages that squeezed Delta earlier in 2026 are easing, and analysts expect third-quarter sales and profit to be the year's best, helped by orders pushed from the second quarter and better margins. That points to a profit recovery.

    It explains why earnings are expected to improve after a weak first half, a key support for the share price.

  • $1.5 billion exchangeable bond creates a share overhang Delta's Singapore unit is issuing $1.5 billion of bonds that can later be swapped into Delta shares at 267-302 baht. No new shares are issued now, but hedging and future selling pressure can cap the stock, which fell about 6% on the news.

    This is the clearest new negative force weighing on the share price this period.

  • Money rotates out of Delta into other electronics names Some investors moved money out of Delta into KCE and HANA, which are seen as having stronger near-term profit prospects, and Delta also tracked its weaker Taiwan parent. This competition for investor money limits how fast Delta can rebound.

    It shows a real counterweight: even with good AI news, investor money is choosing other stocks.
