Super Micro Computer climbs 9% on Cisco partnership

Supermicro Computer's stock surged 8.2% during early trading hours after Cisco announced a strategic partnership with the company. This collaboration aims to expand Cisco's AI infrastructure portfolio by integrating Supermicro's high-density, liquid- and air-cooled server systems into Cisco's Secure AI Factory with NVIDIA offerings.

The deal is expected to benefit enterprise, neocloud, and sovereign cloud customers, with Supermicro solutions becoming available in October 2026. The partnership validates Supermicro's strategic position in the AI infrastructure sector and comes as the stock recovered from a 7.5% decline on Monday. This bounce follows a roughly 60% rally earlier in the month, driven by strong results from Supermicro's fiscal fourth-quarter earnings on August 11.

However, lingering concerns over share dilution and regulatory issues initially weighed on sentiment. The broader market also provided some support, with the Nasdaq Composite up 0.6% and the S&P 500 climbing 0.3%. Investors are currently focusing on the Jackson Hole Economic Policy Symposium and the pending release of the Personal Consumption Expenditures price index, the Federal Reserve's preferred inflation indicator, which is generating cautiously optimistic market sentiment without causing significant market moves.
