Revenue reached RMB 1.035 billion in 2025, up 207.2% year on year, but more than 94% was recognized in the second half, operating cash outflow was RMB 2.137 billion, and the price-to-sales ratio was about 98.7x. Research rating Watch: scarcity is real, but the current price already discounts several years of high-growth delivery, with an ideal buy zone of HKD 21–25.
40/100
Iluvatar CoreX In-Depth Research
A domestic general-purpose GPU designer, Iluvatar CoreX sells compute through training cards, inference cards, and AI solutions, making it a scarce Hong Kong-listed name not yet on the Entity List. In 2025, revenue reached RMB 1.034 billion, gross margin was 54.0%, adjusted loss narrowed to RMB 438.8 million, and the stock traded at roughly 110x price-to-sales. Rating Avoid: inference volume is real progress, but HKD 519 already discounts two to three years of execution, with an ideal buy range of HKD 190-255.
44/100
In-Depth Research on MetaX
MetaX is a domestic full-function GPU designer whose core team came from AMD, with the XiYun C series contributing 94.31% of revenue. 2025 revenue reached 1.644 billion yuan, up 121.26%, while net loss attributable to shareholders was still 789 million yuan, operating cash flow was -1.260 billion yuan, the price-to-sales ratio was about 169x, and three lock-up expiries are due within the year. Research rating Avoid: the company is improving, but the share price has already discounted years of successful execution, with an ideal buy range of 170-220 yuan.
47/100
Cambricon In-Depth Research
Cambricon is a Chinese AI chip design company whose cloud products now contribute almost all revenue and which achieved its first full-year profit in 2025. Revenue reached 6.497 billion yuan, up 453.21% year over year, but operating cash flow was a net outflow of 498 million yuan, the top five customers contributed 88.66% of sales, and trailing P/S was about 93.5x. Research rating Avoid: the earnings inflection has arrived, but the current price has nearly prepaid the next two rounds of execution, with an ideal buy range of 280–340 yuan.
46/100
Moore Threads In-Depth Research
Moore Threads is a domestic full-function GPU designer listed on the STAR Market in late 2025, with revenue already shifting toward AI compute clusters. 2025 revenue reached CNY 1.506 billion, up 243.37%, and 2026Q1 net profit attributable to shareholders turned positive, but recurring profit remained negative, operating cash flow showed a CNY 1.487 billion net outflow, and the stock trades at about 192.6x sales, above Cambricon. Research rating Watch: revenue is scaling, but cash flow and recurring profit have not yet validated the valuation, with an ideal buy range of CNY 166–194.
46/100
Hygon Information In-Depth Research
Hygon Information is a domestic high-end processor design company, with CPUs providing the cash flow from Xinchuang and localization and DCUs providing upside optionality. 2025 revenue reached 14.377 billion yuan, up 56.92%, but the annual report does not split CPU and DCU revenue, while the static P/E is about 264x, more expensive than NVIDIA. Research rating Hold: CPU provides the floor and DCU provides elasticity, but the valuation has already priced in substantial optimism, with an ideal buy zone of 160-176 yuan.

Long-Term Owner's Analysis of Huawei HiSilicon Ascend
Huawei HiSilicon Ascend is Huawei's AI chip and full-stack computing product line, spanning chips, servers, supernodes, software stacks, cloud services, and industry solutions. Huawei generated RMB 880.9 billion in 2025 revenue, RMB 68.0 billion in net profit, and RMB 192.3 billion in R&D spending, while Ascend had 4 million developers and 9,800+ partners by year-end 2025, making it China's primary domestic-substitution option for AI computing infrastructure. Report Rating Avoid: a strategically important business, but not a verifiable, priced, and executable value-investing security for outside public-market investors today.
38/100
Lightelligence In-Depth Zen Horizon Research
Lightelligence is a scarce listed global AI photonic-computing asset, with 18C shares trading roughly 2x above the IPO price within five weeks of listing. Revenue was only RMB 106 million in 2025, with large accounting losses but about RMB 270 million of adjusted operating losses and roughly five years of post-IPO cash runway. Rating Avoid: the company holds 88.3% of the narrow China independent scale-up optical interconnect segment, but Huawei has 98.4% of the overall market and Lightelligence only about 1.4%.
57/100
Broadcom: A Deep-Dive Research Report
Great company, bad price. AI revenue is still accelerating (Q1 at 8.4 billion, Q2 guided to 10.7 billion) with an FCF margin near 42%, yet the current price of 481.57 dollars implies a TTM free-cash-flow yield of only about 1.3% (far below the 4.46% on the 10-year Treasury), already pricing in AI optimism that remains unverified ahead of Q2. Rating Avoid: a high-quality compounder whose price has front-run the very catalysts it still has to deliver, so we cut from Watch to Avoid.
66/100
NVIDIA Investment Memo
Great company, bad price. NVIDIA has evolved from selling chips to selling an entire accelerated-computing platform, with formidable cash flow and an exceptionally strong ecosystem, yet the current share price near 220 dollars already sits at the upper edge of the optimistic scenario, with fair intrinsic value of 110 to 140 dollars and an insufficient margin of safety for conservative investors. Rating Watch: an outstanding business that is still getting stronger, but at today's price you are buying extreme quality rather than buying it cheap.
56/100
TSMC: A Deep-Dive Value Investing Study
The world's leading advanced-logic foundry, holding roughly 70% of the pure-play foundry market, with FY2025 revenue of NT$3.81 trillion and a 59.9% gross margin. At a current Taiwan share price of NT$2,235 and a TTM P/E near 29.5x, the stock already trades above fair value and offers a thin margin of safety. Rating Watch: a world-class business, but the price no longer leaves a cushion.
53/100
AMD: A Deep Dive Through the Lens of a Long-Term Business Owner
AMD is a fabless chip designer whose data-center engine pushed 2025 revenue up to $34.6 billion and lifted its server CPU revenue share to 46%, all on a net-cash balance sheet. Yet its AI-platform moat remains weaker than NVIDIA's, and at roughly $414 the stock trades at about 136x earnings and over 100x P/FCF, far above a $60–190 intrinsic-value range with no margin of safety. Rating Watch: a strengthening business, but a price that prices in more than a decade of good news.
Broadcom: A Value Investing Deep Dive
Broadcom runs a dual engine of high-barrier semiconductors plus VMware software, with FY2025 revenue of 63.89 billion and free cash flow of 26.9 billion dollars; AI semiconductors are powering ahead, yet at roughly 411 dollars the stock already trades near 84x trailing GAAP earnings and 69x TTM free cash flow, leaving no margin of safety. Rating Watch: a high-quality, cash-rich platform priced for near-flawless execution, with an ideal entry of 160 to 220 dollars.
45/100
Micron Technology: A Deep-Dive Value-Investing Analysis
Micron's TTM revenue surged to $58.1 billion on AI/HBM demand, with $23.86 billion in fiscal Q2 alone, and HBM4 is in volume production for NVIDIA's Vera Rubin; but the memory industry's strong cyclicality and capital intensity are unchanged and most contracts are short-term fixed-price, so at roughly $699 the stock sits far above the $120–520 intrinsic-value range with no margin of safety. Rating: Watch.
41/100
Tower Semiconductor Deep Research Report
Analog/power/RF/silicon-photonics specialty foundry with a sturdy balance sheet and high customer process stickiness, but at roughly 127x 2025 P/E and 9.4x tangible net assets, the stock has all but priced in the silicon-photonics and AI-interconnect growth story in advance. Rating: Watch.
51/100
Marvell Technology: A Deep Long-Term Value Study
Built on AI custom silicon, optical interconnect, and data-center networking, with the data center making up three quarters of FY2026 revenue and genuine AI infrastructure demand behind it; yet today's 104x P/FCF and a 0.96% FCF yield (far below the 4.59% 10-year Treasury) already prepay the optimistic case. Fair value sits at $60-90, and the margin of safety is thin. Rating Watch: a strengthening AI-infrastructure platform whose price has run ahead of its value.
NVIDIA: A Deep Value-Investing Study
Paying a high price for an exceptional business. NVIDIA is now a full-stack platform for AI infrastructure, and its multi-layered moat (the CUDA ecosystem, NVLink system integration, and developer mindshare) is still widening; but at the current ~$225 it trades at 46x PE with a 1.8% FCF yield, the fair buy range is $120 to $160, and the price already sits near the upper edge of the optimistic scenario. Rating Watch: an outstanding franchise priced for sustained perfection rather than a bargain with a thick margin of safety.
40/100
Cerebras Systems: A Long-Term Business Owner's Perspective
Good technology, bad price. Cerebras has won OpenAI and AWS validation in the low-latency inference niche, but 86% of 2025 revenue came from two UAE-linked customers, operating cash flow is weak, and governance carries real flaws. Rating Avoid: at roughly $280 post-IPO, the price already prepays for a decade of flawless execution, while conservative-to-reasonable intrinsic value runs only $20-50 per share.
