Tongfu's profit surge and AI packaging demand drive the story

First-half profit jumps on AI and chip localization Tongfu reported first-half 2026 net profit of 1.717 billion yuan, up 288-337% from a year earlier, on revenue of 16.041 billion yuan. The company credits AI computing power buildout and faster chip localization, which lifted demand for its mid-to-high-end packaging services and boosted profit.
This is the core new fundamental result that explains why the stock is moving and gives the big picture.
Advanced CPO packaging opens new growth path Tongfu has entered the supply chain for co-packaged optics (CPO), an advanced packaging technology used in AI data centers. This puts it alongside other optical and semiconductor firms benefiting from the AI computing boom, giving it a new source of revenue beyond traditional chip packaging.
It shows a new technology-driven demand channel that supports future growth and investor interest.
CXMT stake adds paper profit and supply-chain tie Tongfu was one of eight chip firms that invested in memory maker CXMT's stock market listing. Its stake gained about 736 million yuan in paper profit on the first day, though shares are locked up for 18 months. The deal also strengthens its ties to a key domestic memory producer.
It highlights a capital gain and strategic supply-chain link that can affect sentiment and future orders.
Institutions trim holdings even as overall ownership stays high The half-year report shows 180 institutions hold 32.20% of Tongfu, but the top ten institutional holders cut their stake by 4.11 percentage points from the prior quarter. Some funds and Hong Kong clearing reduced positions, a caution sign even as total institutional ownership remains large.
It provides the main counterweight to the positive earnings and technology news, showing some big investors are selling.

LONGi's H1 loss deepens, but policy and new tech offer hope

H1 loss forecast LONGi expects a first-half loss of 3.4–3.8 billion yuan, part of a sector-wide loss exceeding 13 billion yuan. This confirms the industry's severe oversupply and price wars, weighing on the stock.
Directly explains the company's weak financial performance and negative sentiment.
Excise tax on solar cells China will impose a 2% excise tax on solar cells from April 2027, rising to 4% in 2028. The tax aims to curb overproduction and price wars, which could help LONGi by reducing industry oversupply.
New regulation that could improve industry dynamics and benefit LONGi.
Mandatory standards and anti-cutthroat policies Three mandatory national standards for solar products take effect in January 2027, accelerating the exit of outdated capacity. Combined with anti-cutthroat competition policies, this may lead to a policy bottom and market bottom, supporting LONGi's long-term recovery.
Shows regulatory efforts to rebalance supply and demand, a key driver for LONGi's future profitability.
Perovskite investment LONGi plans to invest 203 million yuan in a 100MW perovskite tandem cell pilot line. This next-generation technology could enhance efficiency and open new markets like space photovoltaics, positioning LONGi for future growth.
Highlights LONGi's innovation and capital allocation to advanced technology, a potential long-term catalyst.
