Cisco Soars 32% in a Month, Arista Falls 10%, Broadcom Drifts: The AI Networking Trade Has a Clear Winner

The AI networking trade shows leadership rotation, with Cisco surging while Arista slips and Broadcom advances in intraday trading. In midday action, Arista trades up about 3-4 percent, Cisco slips around 2.5 percent, and Broadcom moves higher by about 2 percent, underscoring a fast-changing landscape even as all three face the same hyperscaler capex cycle. Cisco rebounded after a strong Q3 FY2025 report, posting revenue of $15.84 billion, up 12 percent year over year, with networking revenue up 25 percent. It lifted its FY2026 AI infrastructure order target to $9 billion from $5 billion and raised AI revenue guidance to $4 billion from $3 billion, while data center switching orders grew more than 40 percent YoY. Arista contends with margin concerns and customer concentration with hyperscalers, guiding Q1 2026 non-GAAP gross margin to 62-63 percent. Broadcom posted Q1 FY2026 AI semiconductor revenue of $8.4 billion, up 106 percent YoY, and guided Q2 AI semi revenue to $10.7 billion, illustrating a robust AI hardware cycle that supports a continued rotation in leadership.
