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.

Fabrinet's AI-driven growth is real, but the stock is priced for perfection

Thailand photonics investment surge highlights Fabrinet's role in AI supply chain Thailand's BOI revealed over 82 billion baht invested in photonics projects over five years, naming Fabrinet as a key producer for Nvidia, Cisco, and AWS. This confirms strong demand for Fabrinet's optical communication products used in AI data centers, supporting revenue growth.
Shows underlying demand strength that drives Fabrinet's business, a key reason the stock has risen over time.
Potential FCC ban on Chinese optical transceivers could benefit Fabrinet The FCC is drafting a rule to ban imports of new Chinese optical transceivers, which could shift business to US suppliers. Fabrinet, a major contract manufacturer for optical transceivers, could gain market share as customers seek non-Chinese sources.
A regulatory change that could boost Fabrinet's orders and pricing power, directly affecting future revenue.
Record earnings and strong guidance, but margins and cash flow disappoint Fabrinet reported record Q4 revenue of $1.316 billion and guided Q1 above expectations, but gross margin fell 30 basis points and free cash flow turned negative due to heavy capital spending. The stock dropped 18% as investors worried about profitability and cash generation.
This is the core tension: strong top-line growth but weakening bottom-line metrics that spooked investors.
Valuation concerns and profit-taking drive sharp selloff despite beat After an AI-driven rally, Fabrinet's stock trades at about 46 times earnings. Even with record results and above-consensus guidance, the market's expectations have risen so high that any sign of margin pressure or cash burn triggers a selloff, as seen in the 18% drop.
Explains why the stock fell despite good news, highlighting the risk of high expectations.
