SPY edges ahead in a higher finish as mixed PMIs give way to overnight tariff whiplash
QQQ finished 0.47% higher and SPY gained 0.58%, leaving SPY ahead by 0.11 percentage points after both opened higher. Services PMI beat expectations while manufacturing missed, and Nvidia's reported $6 billion Poolside AI licensing agreement kept AI investment in focus. Overnight, U.S.-Canada tariff talks moved from reported progress to collapse, while U.S.-Iran sanctions threats followed Hormuz shipping constraints and diplomatic contacts.
