The broad market is experiencing a significant rally today, with the S&P 500 up over 1%. The primary driver is a de-escalation in geopolitical tensions, specifically news of renewed negotiations between the U.S. and Iran. This has led to a sharp drop in crude oil prices, alleviating investor concerns about inflation and potential economic disruption. This positive development has fostered a "risk-on" sentiment, contributing to widespread gains across multiple sectors. The strong Q2 earnings season provides a supportive backdrop, but the immediate catalyst is the relief from geopolitical uncertainty.
