ARM.US rose 10.03% to $282.47, reaching a peak increase of 10.81% during the session, setting a new historical high, and its market capitalization surpassed $300 billion for the first time; its leveraged ETF (ARMG.US) rose 19.83% to $29.25, with a peak increase of 21.59% during the session. Marvell Technology (MRVL.US) rose 3.93% to $194.15, with a peak increase of 4.16% during the session; its 2x leveraged ETF (MVLL.US) rose 7.12%. Broadcom (AVGO.US) rose 0.89% to $421.49. Nvidia (NVDA.US) showed relatively restrained performance during the session, slightly rising 0.24% to $224.01 as of the time of writing, with a peak increase of 1.76% reaching $227.40 during the session. After the earnings report, buying concentrated at the moment of opening, followed by a continuous retreat in gains; the 2x leveraged ETF (NVDL.US) rose 0.33% (with an intraday fluctuation of 3.43%), while the inverse ETF (NVDD.US) fell 0.71%. On the downside, Intel (INTC.US) fell 1.87% to $116.74, with its derivative INTW.US falling 3.11%, amplifying the downward movement; AMD (AMD.US) fell 1.74% to $439.79; Cerebras Systems (CBRS.US) fell 1.25% to $287.07, opening at $293.70, close to the day's high, and then continuously declined to $283.05, with a maximum intraday drop of about 4%, showing a typical high open and low close pattern; its 2x leveraged ETF (CBRG.US) fell 2.43%. In terms of news, Nvidia announced its Q1 performance after the market closed yesterday, with revenue growing 85% year-on-year, exceeding expectations, and the Q2 outlook also better than market expectations. However, after a surge in stock price post-announcement, there was a significant retreat in gains, reflecting that the market has already priced in expectations for its performance. Against this backdrop, market funds shifted towards the "second-tier leaders" in the AI computing power chain—ARM benefited from the "CPU Renaissance" theme, with the industry generally reflecting that the ratio of CPU to GPU in AI training is rapidly shifting from the traditional 1:8 towards 1:1 or even 4:1. Some AI startups have begun to significantly increase CPU procurement, and the importance of CPUs has been revalued by the market; Marvell continued the "Trainium industry chain revaluation" main line, combined with the recent $2 billion strategic investment from NVDA and AMD's strategic stake, further elevating its position in the custom silicon track. Regarding CBRS, as a core speculative target of the earlier "next-generation AI chips benchmarked against Nvidia/AMD" theme, after Nvidia's performance was realized, market sentiment turned rational, showing a typical "good news realized sell-off" reaction ### Related Stocks - [INTC.US](https://longbridge.com/en/quote/INTC.US.md) - [ARM.US](https://longbridge.com/en/quote/ARM.US.md) - [AMD.US](https://longbridge.com/en/quote/AMD.US.md) - [MRVL.US](https://longbridge.com/en/quote/MRVL.US.md) - [ARMW.US](https://longbridge.com/en/quote/ARMW.US.md) - [SOXL.US](https://longbridge.com/en/quote/SOXL.US.md) - [SOXX.US](https://longbridge.com/en/quote/SOXX.US.md) - [XSD.US](https://longbridge.com/en/quote/XSD.US.md) - [SMH.US](https://longbridge.com/en/quote/SMH.US.md) - [ARMG.US](https://longbridge.com/en/quote/ARMG.US.md) - [SOXQ.US](https://longbridge.com/en/quote/SOXQ.US.md) - [PSI.US](https://longbridge.com/en/quote/PSI.US.md) - [FTXL.US](https://longbridge.com/en/quote/FTXL.US.md) - [ARMU.US](https://longbridge.com/en/quote/ARMU.US.md) - [MVLL.US](https://longbridge.com/en/quote/MVLL.US.md) - [AVGO.US](https://longbridge.com/en/quote/AVGO.US.md) - [NVDA.US](https://longbridge.com/en/quote/NVDA.US.md) - [NVDL.US](https://longbridge.com/en/quote/NVDL.US.md) - [NVDD.US](https://longbridge.com/en/quote/NVDD.US.md) - [CBRS.US](https://longbridge.com/en/quote/CBRS.US.md) - [CBRG.US](https://longbridge.com/en/quote/CBRG.US.md) - [NVD.DE](https://longbridge.com/en/quote/NVD.DE.md) ## Related News & Research - [Marvell Technology Gets Boost From New AMD Stake](https://longbridge.com/en/news/287070913.md) - [Intel Is Supposed to Be in a New CPU Era But Its Losing Market Share to AMD and Arm](https://longbridge.com/en/news/286646639.md) - [Marvell Technology Has a Hidden Growth Engine That Could Cause MRVL Stock to Skyrocket](https://longbridge.com/en/news/286602332.md) - [2,074 Shares in Advanced Micro Devices, Inc. $AMD Bought by Sapient Capital LLC](https://longbridge.com/en/news/287034881.md) - [BUZZ-Citigroup sees server CPU market reaching $132 billion by 2030, Intel to lead](https://longbridge.com/en/news/286771641.md)
