ACM Research carries binary China risk: China is about 97% of its business, and authorities could stop it any day, forcing management to choose between San Jose and China. The CCP's threats toward other countries make that exposure uglier, whatever the company's $4B revenue ambition. x.com  x.com  x.com 

Some semiconductor stocks have returned to reasonable valuations as fundamentals improve, making recent declines buying opportunities. Many had traded at two to three times their median valuations; the correction brought some back toward normal, while sustained AI spending should benefit suppliers for years. x.com 

ACM Research's cleaning business must have driven its unexpectedly strong revenue, including a higher-margin cleaning product. Q3 '36 revenue beat estimates by 20%; last quarter's voiceover foreshadowed the product, but the full release has yet to show the mix. x.com  x.com 

ASML's reported inability to make enough machines for the next two years is a buy signal for the whole AI stack. Its stock still sold off despite that shortage. x.com 

Qnity Electronics is a picks-and-shovels way to invest in AI without picking which chipmaker wins, because it supplies the materials chipmakers consume throughout manufacturing. Its photoresists, CMP pads and slurries, packaging and thermal materials, Kapton films and specialty chemicals are consumables replenished as wafers move through fabs, creating recurring demand across a diversified customer base. Risks include chip spending cycles, intense competition and geopolitical exposure in Asia. … Show more

ACM Research should benefit as China's wafer fab equipment spending soars over the next couple of years across memory and leading-edge logic, more than offsetting lower mature-node spending. Its advanced packaging sales to non-Chinese clients are also growing well, and valuation looks reasonable after the recent pullback. x.com 

Micron, TSMC, ASML, Penguin Solutions and Aehr Test Systems' AI bottleneck thesis got stronger even as their stock prices did not. Micron and TSMC beat and raised, ASML reaffirmed, Penguin executed and Aehr delivered a record quarter. AI demand, capex and supply constraints are all still there. x.com 

Micron's $1 trillion market cap echoes Cisco in 2000, when the story got too big and multiples went parabolic before the bloodbath. An AI bubble pop is inevitable. x.com 

ACM Research is breaking out cleanly from a big base on strong earnings and theme momentum, the combination behind some of the biggest winners. It builds the tools that clean and process wafers in every chip factory, yet remains one of the least talked-about names. x.com 

NVIDIA, Broadcom, Micron and TSMC should be worth less because AI risk has risen while the expected reward has not. The CEOs of Anthropic, OpenAI, SpaceX and Tesla have said AI risks killing all humans and needs to slow down, yet not a single analyst cut ratings or price targets on these chipmakers. In game-theory terms, higher risk with the same reward makes the bet worse. x.com
