Microchip Technology CEO Steve Sanghi warned about a 'bubble' in the data center market during the company's earnings call. He noted that data centers account for 16.7% of Microchip's business, suggesting the company may outperform others more exposed to data-center spending. Microchip's stock fell 13.9% on the day, while other data-center-related stocks like Nvidia, Vertiv, and Ciena also saw significant declines.

Cisco (CSCO) also declined 8% after a downgrade. Arista's Q3 revenue grew 58.5% to $3.66B, with improved gross margins. Investors fear Democratic Congress may slow data center buildout.

Marvell (MRVL) acquiring Lumentum (LITE) may prompt Ciena (CIEN) and Cisco (CSCO) to diversify suppliers, according to BofA analysts.
