$Arm(ARM.US)This thing actually has a small proportion of its shares in public float.Most of it is in Masayoshi Son's hands.Boss Son says he won't sell a single share.As a small position for exposure to the CPU sector,I'll continue holding it.

Some risk warnings, ARM is just a small position for meCurrently, my ARM position accounts for about 3.5%, with no plans to increase itIf the CPU sector starts to rally in the future, I will gradually reduce my position, eventually maintaining it at around 3%.ARM is a company with ecosystem barriers but weak pricing power, limited revenue growth, and profitability squeezed by persistently high R&amp;D expenses:1) Although it has a high market position, its weak pricing power leads to sluggish revenue growthARM monopolizes the mobile market and continues to gain share in the server market, but its pricing power is weak. Once ARM tries to increase licensing fees or royalties, it may force major customers to switch to open-source architectures (RISC-V) for self-development to control costs. In fact, many giants already have their own self-developed architectures, but they haven't been widely adopted yet, and their universality still can't match ARM's.2) Profit quality eroded by high R&amp;D expensesARM has high gross margins but ordinary net margins. It must continue to invest heavily in R&amp;D to maintain optimization of existing architectures and develop more cost-effective new architectures amid ongoing competition from open-source architectures.$Arm(ARM.US)

Just watched the CNBC interview with Jensen Huang and the CEO of CoreWeaveJensen said at the beginning: CRWV has always used Nvidia GPUs, but now they're also going to add Nvidia CPUsThis opening statement is quite significant, indicating: Nvidia is actively pushing into the server CPU marketAlthough the industry still predominantly uses x86 architecture CPUs, the performance of Nvidia's previous generation Grace CPU+BlueField DPU combination has shown potential to surpass traditional x86 solutions. Due to user habits and ecosystem dependencies, the migration process was slow initially, but as Nvidia actively promotes its superior CPU solutions deeply integrated with its ecosystem, its market share in server CPUs is expected to grow significantly in the future.Nvidia's CPUs have always been based on ARM architecture. Meanwhile, cloud giants like Google and Amazon are gradually developing their own CPUs to reduce costs - which also relies on ARM architecture support.Therefore, judging the technology and market trends in the CPU field from a long-term perspective, the order of ecosystem importance could be summarized as: ARM &gt; AMD &gt; Intel.This is also why I chose ARM for my investments in the CPU sector$Arm(ARM.US)$AMD(AMD.US)$Intel(INTC.US)
