ACM Research trades at a discount of more than 50% to the value of its China subsidiary, which is worth over twice the parent and has posted back-to-back gains above 15%. China's mainland market rally should eventually flow through to consumption. x.com 

ACM Research looks underpriced because its Chinese subsidiary alone has a backlog equal to about half the company's market cap. ACM Shanghai's backlog rose 88.2% to $2.5B, yet the stock barely reacted. x.com  x.com 

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 

ACM Research stands out among holding-company NAV discounts because its subsidiary is growing independently and an H-share subsidiary listing is coming soon, making it one of the biggest discounts with a path to unlock and a candidate for more concentration. Similar discounts at Korean holding companies such as Iljin Holdings and Simmtech Holdings look less trustworthy for a NAV unlock given governance. This is still early research, not a formal conclusion. x.com 

ACM Research is the best idea under $5B in market cap right now because China is going to keep pushing for localization. Ongoing dilution of its stake in its Shanghai subsidiary is a valid concern, but a necessary one. x.com  x.com 

ACM Research looked great as a value stock, but less so once it is clear it only makes wafer-cleaning equipment. @masayoshisson sees it, like nearly every AI stock, showing textbook complacency before complete capitulation, perhaps a few months after an Anthropic IPO. x.com 

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 

Chinese semiconductor localization names like ACM Research and NAURA look like attractive opportunities for the second half of 2026 because CXMT's IPO should channel capital their way. Chinese sell-side analysts say CXMT's market cap right after listing could reach at least RMB 5 trillion, a frenzy Western investors underestimate, and most of the money it raises will likely flow into localization stocks. x.com 

Chinese names like Alibaba and ACM Research have room to catch up while valuations elsewhere get absolutely out of hand. Per @negligible_cap, Cerebras is targeting up to $4B in its US IPO at a $40B valuation. The China catch-up trade is obvious, yet still non-consensus. x.com 

RS Technologies' asset discount persists amid high management ownership, no activist and no real investor interest. Those are the reasons given for why it trades so cheaply despite its Chinese holding. x.com
