Why these two companies

Broadcom beat Wall Street's fiscal Q3 estimates on September 2, 2026, with revenue up 86% year-over-year on soaring AI chip demand, yet shares still sank as investors focused on Q4 guidance that only roughly matched forecasts. That same beat-but-sell-off pattern has hit AI networking rival Marvell Technology since its own record Q2 report on August 27, 2026, making this the day's clearest head-to-head test of whether the market's AI-chip enthusiasm is cooling even for the sector's strongest growth numbers.

The research

Broadcom makes computer chips and software that power much of the internet's AI infrastructure, including custom chips built specifically for big cloud companies. Marvell Technology makes similar kinds of chips and networking technology that connect AI computers together, competing with Broadcom for many of the same customers.

One reason to like Broadcom: it just reported much higher sales than a year ago, driven by huge demand for AI chips, and it has a broader business that also includes software, giving it more ways to grow. One reason to like Marvell: it just posted record sales too, with its data center business growing fast, and some analysts think its stock has more room to run compared to its price target.

Something to keep in mind for Broadcom: even after beating expectations, its stock fell because its outlook for the next few months only matched what investors already expected, showing how high the bar has become. Something to keep in mind for Marvell: its stock has been sliding for several days in a row as investors worry about profit margins even though its growth numbers were strong.

Both companies just gave their full earnings updates this week, so today's price moves are more about how investors are reacting to what was already announced than about new news.
