US Stocks Rally on US-Iran Deal Hopes; Philly Fed Surges 5%, TSMC Up Over 4%

US stock markets experienced a broad rally on June 15, with the Philadelphia Semiconductor Index leading the charge with a gain of over 5%. The Dow Jones Industrial Average closed at a historic high, reflecting positive investor sentiment.

The market's upward movement was largely driven by news of a preliminary agreement between the United States and Iran. This development led to a significant drop in US crude oil futures, which fell 4.9% to their lowest level since March. The decrease in oil prices benefited airline and cruise line stocks, which are sensitive to energy costs, although energy companies themselves faced pressure.

Technology stocks were particularly strong. Nvidia climbed 3.54%, Micron soared 10.84%, Qualcomm rose 4.29%, and AMD gained 6.98%. Meta was up 4.77%, Apple increased by 1.82%, Alphabet added 2.69%, Microsoft gained 2.31%, and Amazon saw a 3.13% rise. Taiwan Semiconductor Manufacturing Company's ADR also performed well, jumping 4.12% to $441.40, while UMC ADR increased by 6.70% to $23.08.

The Dow Jones Industrial Average finished up 468.77 points, or 0.92%, at 51,671.03. The Nasdaq Composite surged 3.07%, adding 795.10 points to reach 26,683.94. The S&P 500 index climbed 1.65%, gaining 122.83 points to close at 7,554.29. The Philadelphia Semiconductor Index, often seen as a bellwether for the tech industry, closed at 14,099.62, up 5.45%.
