Marvell Technology's stock tumbled 6.44% in after-hours trading on Wednesday, sharply reversing its strong intraday gains. The semiconductor company had extended a rally fueled by Nvidia CEO Jensen Huang's endorsement earlier in the week, but the momentum was halted after the market closed.
The after-hours plunge appears directly linked to sector-wide concerns triggered by earnings results from competitor Broadcom. Broadcom reported quarterly revenue that missed analyst estimates, sending its own shares tumbling over 13% in extended trading. In its report, Broadcom highlighted intensifying competition in the custom AI chip market, noting that rivals like Marvell Technology are making inroads with key hyperscale customers.
Investors reacted to the news by selling semiconductor stocks after the closing bell, concerned that the explosive growth in AI-related chip demand might face headwinds from increased competition and potential supply chain challenges. The Broadcom results served as a stark reminder of the high expectations priced into the sector following its recent record-breaking rally.
