Tensions over Iran put S&P 500 and Nasdaq under pressure, with semiconductor stocks falling

7On 13as geopolitical tensions related to Iran escalated, S&P 500and Nasdaq futures declined, and U.S. stocks opened lower. Early in the session, investors reacted sensitively to geopolitical risk.

The semiconductor sector led the weakness on the day. Semiconductor-related stocks fell broadly, and selling pressure emerged across the sector.

Individual large-cap technology stocks were mixed, but shares of companies with higher reliance on semiconductors opened weaker. Moves in the futures market affected sentiment in the cash market.

That day’s market conditions showed that geopolitical uncertainty increases short-term market volatility. Investors appeared to be re-evaluating risk factors.

Until the market close, the trend could still change depending on additional announcements or events. When setting short-term investment strategies, volatility expansion should be kept in mind.

This move could have direct and indirect effects, especially on sectors sensitive to global supply chains and trade conditions. It will be necessary to keep an eye on the flow of related news going forward.
