Wall Street futures slip as Nvidia earnings, Fed speech loom

US stock futures fell Monday as markets braced for a week of major catalysts, including Nvidia earnings, new Iran sanctions, and a Federal Reserve speech. Nasdaq 100 futures dropped 0.6%, while S&P 500 and Dow futures saw smaller declines. Technology stocks remain sensitive after rising Treasury yields pushed the S&P 500 tech sector down over 3% last week. Nvidia reports quarterly results Wednesday, entering after five consecutive daily declines, with investors focused on AI server price increases and potential margin pressures. Oil prices hovered near $91 Brent and $85 WTI ahead of Treasury Secretary Scott Bessent's sanctions announcement. A renewed US-Canada trade dispute added macro uncertainty, while Fed Chair Kevin Warsh's Jackson Hole speech Friday could reshape rate expectations.
