US semiconductor stocks closed sharply lower on July 7 (US Eastern Time) as Samsung Electronics plunged despite reporting operating profit nearly 20 times higher year-over-year. The S&P 500 fell 0.45% to 7503.85, the Nasdaq declined 1.16% to 25818.69, and the Dow Jones Industrial Average dropped 0.25% to 52925.15 after surrendering intraday record highs. The sell-off intensified as the US Treasury revoked Iran oil sanction exemptions in response to a Strait of Hormuz tanker attack, sending Brent crude up 3.01% to $74.16 per barrel and WTI up 2.76% to $70.44 per barrel.
