Cisco Falls 7% on Morgan Stanley Downgrade; Ciena Plunges 15%, Arista Networks Tumbles 10%
Cisco Systems (CSCO) fell 7% after Morgan Stanley downgraded it to Equal-weight, citing AI-driven margin pressure and a strong recent rally. The firm lowered its price target to $120 from $135. Ciena (CIEN) and Arista Networks (ANET) also dropped, 15% and 10% respectively, due to concerns about AI infrastructure spending. Cisco's diversified business model has cushioned its decline compared to its peers.
