US stocks closed higher on Wednesday, as the S&P 500 rose 0.7% and the Nasdaq 100 jumped 1.4% with investors looking past Middle East tensions. The Dow added 0.5% points as a retreat in oil prices and robust economic data calmed growth fears. Treasury Secretary Scott Bessent signaled forthcoming measures to support Persian Gulf oil flows, helping WTI crude post its first decline since the conflict began. Despite Bessent confirming that 15% global tariffs take effect this week, sentiment was bolstered by ADP data showing stronger-than-expected private job growth and easing inflation pressures in the services sector. Tech shares led the rally, with Micron and AMD each surging over 5.5%, while Amazon rose 3.9%. Financials also bounced, as KKR and Blackstone gained roughly 3% each, signaling a recovery from recent private credit volatility. Meanwhile, laser manufacturer NLight hit a 52-week high with a 6.3% jump, reflecting a broader shift back into technology and growth stocks.
