Investors reacted to U.S. inflation data that came in hotter than expected [1, 2]. Higher inflation typically prompts concerns that the Federal Reserve may maintain higher interest rates for a longer duration to cool the economy. This environment often puts downward pressure on equity valuations, particularly for growth-oriented stocks found in the Nasdaq [3].

Adding to the market volatility were growing concerns regarding the U.S.–Iran ceasefire [1, 2]. Reports indicated that the agreement was becoming increasingly tenuous, raising the prospect of renewed conflict in the region. Geopolitical instability in the Middle East frequently impacts global energy markets, and creates uncertainty for international trade [3].
