Konfoong profit surges on AI chip demand; funds pile in

Profit guidance nearly doubles on AI-driven chip demand Konfoong told investors first-half 2026 profit would jump 90%-122% year on year, as global chip demand and AI buildout drive wafer-fab expansion and rising sales of its ultra-pure metal targets and precision parts. Stronger earnings make the shares more attractive.
The profit surge is the core fundamental force behind the stock's move.
Big-name funds add Konfoong as they rotate into tech Fund managers including Liu Yanchun added Konfoong to their top holdings in the second quarter, cutting consumer staples like baijiu to buy tech growth. More institutional money buying the stock supports its price.
Institutional demand is a direct new buyer force for the shares.
Half-year report confirms 113.61% profit growth The actual semi-annual report showed revenue up 30.68% to 2.737 billion yuan and net profit up 113.61% to 540 million yuan, landing inside the earlier guidance range. Confirmed results remove doubt and underpin the stock.
The reported results validate the earlier forecast, the key hard number for investors.
New private equity fund is a side capital move Konfoong joined Silan Integration and others to set up a Shanghai private equity fund. It is a small capital allocation with no clear near-term effect on earnings, so it neither strongly helps nor hurts the stock.
It is the only other new company-specific event, but its price impact is unclear.

AMEC profit surges, expands capacity and domestic share

First-half profit jumps over 280% AMEC guided to and then reported first-half net profit up roughly 282-311% year on year, with revenue up about 35%. Part of the gain came from selling a stake in Piotech, so not all profit is from core equipment sales.
Earnings growth is the clearest fundamental driver of the stock's value.
3.5 billion yuan Lingang expansion AMEC will invest 3.5 billion yuan in phase two of its Lingang base, making etching, inspection and deposition tools. Full production is targeted at 3 billion yuan of annual sales, expanding capacity to meet demand.
This is a concrete, large capital commitment that signals confidence in future orders.
Domestic chip tool demand accelerates Chinese fabs are buying more locally made equipment after Western supply restrictions. AMEC's etchers compete with Lam Research, and its share of the China market is rising toward a leading position, with 800 reaction chambers shipped to top overseas logic customers.
This is the core long-term demand story that supports revenue growth.
New investment vehicles and Wuhan unit AMEC joined a 2.1 billion yuan venture fund with Montage and Jinqiao Capital, and set up a Wuhan subsidiary with 50 million yuan registered capital. These moves widen its investment reach and equipment manufacturing footprint.
Shows AMEC is deploying capital to expand its ecosystem and production capacity.
