EVERYTHING
According to Stocktwits, shares of leading semiconductor firms experienced a significant rally on Thursday, reaching their highest levels in over a year. The surge was primarily attributed to the escalating global demand for artificial intelligence chips and increased capital expenditure within major data centers.
AMD and Marvell lead the hardware surge
Advanced Micro Devices (AMD) saw its stock climb more than 1% during the day, reaching an intraday peak of $310.22. The company is currently maintaining a positive momentum that has lasted for seven consecutive weeks. This upward trajectory was further bolstered by favorable analyst sentiment; Stifel recently upgraded its price target for AMD to $320 while maintaining a 'Buy' rating. Data from Koyfin indicates that 36 out of 49 analysts covering the stock hold a 'Buy' or higher rating.
Marvell Technology (MRVL) outperformed its peers with a gain of over 5% to reach $167.86, marking its fifth straight session of growth. The networking chipmaker has secured several high-profile deals with hyperscalers and recently announced the acquisition of Polariton Technologies to enhance its photonic solutions. Additionally, reports suggest Marvell is in discussions with Google regarding custom chip development.
- AMD shares have surged more than 237% over the past year.
- Marvell Technology shares have risen more than 207% in the same period.
- AMD breached a $500 billion market cap during after-hours trading following positive sentiment from Intel's earnings.
Micron benefits from memory demand
Micron Technology (MU) also reached a 52-week high of $493.62 before closing slightly lower by about 1%. The company is currently on track for its fourth week of gains, largely driven by the soaring demand for high-bandwidth memory products required for Agentic AI and broad-based servers. Micron reported that its second-quarter 2025 revenue nearly tripled to $23.86 billion, significantly exceeding analyst expectations due to structural supply constraints.
Despite the stock's stellar performance—which includes a massive surge of more than 560% over the past year—retail sentiment on Stocktwits has shifted toward 'bearish' territory. This contrasts with the 'extremely bullish' sentiment seen for AMD and Marvell, where message volumes remain high. While institutional analysts remain largely positive on Micron, retail traders appear to be cooling on the stock following its rapid price appreciation.
The semiconductor industry continues to serve as a primary beneficiary of the AI infrastructure build-out, with hardware providers capturing significant market share through specialized networking and memory solutions.
