Nasdaq Slides as SpaceX Rout and Rate Hike Fears Counter U.S.-Iran Peace Hopes

U.S. equities faced a bifurcated trading session as a sharp correction in speculative technology shares offset optimism regarding cooling geopolitical tensions. The Nasdaq Composite dropped 1.3%, weighed down by a significant 16% plunge in SpaceX shares and a retreat in Alphabet Inc. while the Dow Jones Industrial Average managed a modest 0.3% gain. The volatility coincided with a massive $7.5 trillion options expiry event that drove trading volumes to record highs.

Market sentiment was initially bolstered by news of an interim peace agreement between the U.S. and Iran. The diplomatic breakthrough led to a retreat in Treasury yields and a slide in oil prices, easing immediate inflation concerns. However, the rally in chipmakers, which saw a 6.4% jump earlier in the session, was eventually eclipsed by the broader rotation out of megacap technology stocks.

Adding to the complexity, traders are recalibrating expectations for monetary policy. Despite the geopolitical relief, firm rhetoric from central bank officials regarding the inflation fight has markets pricing in an 85% chance of a rate hike by October. This hawkish shift pushed short-dated bond yields higher and dampened the enthusiasm for risk-on assets that had previously propelled the market to recent highs.

The session also saw increased interest in emerging market structures, with the NYSE and Nasdaq exploring the tokenization of securities. At the same time, retail participation remains high, particularly among Gen Z investors who continue to favor high-risk pursuits such as meme stocks and complex options strategies, even as professional fund managers warn of potential overvaluation in current market leaders.
