S&P Futures Tread Water Ahead of Warsh’s Jackson Hole Speech; Marvell Sinks After Earnings

S&P 500 E-Mini futures held steady at a -0.05% decline as investors awaited Fed Chairman Kevin Warsh's first Jackson Hole speech. Nasdaq 100 futures underperformed, dropping -0.30%, as Marvell Technology (MRVL) faced a significant -8% drop in pre-market trading following a modest Q2 beat and slightly higher-than-expected Q3 guidance.

Other chipmakers and AI infrastructure stocks also experienced pre-market losses, erasing some gains driven by Nvidia's bullish outlook. Warsh's speech at the Economic Policy Symposium in Jackson Hole, Wyoming, is expected to provide clarity on the Fed's economic outlook and strategy for managing inflation, with investors closely watching for details on his near-term policy considerations.
