Blowout profit forecast met with sell-off as memory chip rally cools

First-half profit forecast surges over 2,000% Shannon Semiconductor expects net profit of 3.5–4.0 billion yuan for H1 2026, up 2,117%–2,434% year-on-year. The company credits high memory chip demand, rising prices, better distribution margins, and its own 'Haipu Storage' brand entering mass sales. This is a fundamental positive that supports the stock's value.
The earnings pre-announcement is the core new fundamental event driving the stock's narrative.
Stock plunges 20% despite strong earnings On July 17, Shannon Semiconductor hit the daily 20% limit-down even after the huge profit forecast. Investors had already pushed the stock up in a months-long rally, and the good news was priced in. This shows how high expectations can turn positive news into a sell signal.
This is the key new market reaction that explains why the stock is moving down despite good news.
Memory chip sector tumbles, dragging stock down On July 13 and 16, memory chip stocks fell sharply. Demingli hit limit-down twice, and Shannon Semiconductor dropped nearly 20% on July 13. Weakness in US memory stocks like Micron also weighed on sentiment. Sector-wide selling pressure pulled the stock lower.
Sector-wide weakness is a major force pushing the stock down, separate from company-specific news.
Industry outlook still strong but price increases slow Analysts maintain that memory chip supply will stay tight through at least late 2027, supporting long-term demand. However, memory price increases slowed in June, and some companies like Demingli warned of quarter-on-quarter profit declines. This creates uncertainty about how long the boom can last.
This provides the necessary counterweight: the long-term story is intact but near-term momentum may be fading.

Weichai's data-center power and hydrogen engine drive growth

Data center power demand surges Weichai's data center power business is booming, with natural gas and diesel generator sales strong. In H1 2026, diesel generator sales exceeded 1,400 units, already above full-year 2025, and high growth is expected to continue. This rising demand boosts revenue and profit.
This is a key new growth driver that directly lifts Weichai's earnings and stock price.
Hydrogen engine breakthrough Weichai launched the world's first China VI-compliant heavy-duty hydrogen engine, a major tech milestone. It plans mass production and supports national hydrogen projects. This opens a new long-term market and strengthens its technology leadership.
This new product innovation positions Weichai for future growth in clean energy.
Strong H1 earnings and cash flow First-half net profit rose 36.5% to 7.7 billion yuan, with operating cash flow up 66%. Q2 profit jumped 57.4%. The company also plans higher dividends and buybacks, returning cash to shareholders. This solid financial performance supports the stock.
Earnings growth and shareholder returns are fundamental drivers of stock price.
Shareholder increase and SOFC progress The controlling shareholder plans to buy 200-400 million yuan of A-shares, signaling confidence. Meanwhile, SOFC products aim for mass production this year, targeting the clean energy market. These moves support the stock price.
Shareholder buying and new product progress are positive signals for investors.
