Stocks opened sharply lower on Monday, reflecting the immediate market response to U.S. airstrikes on Iran over the weekend. However, the main indexes quickly reversed their downward trajectory, ultimately finishing the day mostly higher. By market close, the Dow Jones Industrial Average fell slightly by 0.2% to 48,904, while the broader S&P 500 crept up 0.04% to reach 6,881. The tech-heavy Nasdaq Composite gained 0.4%, finishing at 22,748. Although the week and month began in a mixed manner, this was a notable recovery from losses exceeding 1% that the trio experienced at the start of trading.
The initial decline was triggered by news of coordinated military operations initiated by the U.S. and Israel against Iran, resulting in the death of Iran’s Supreme Leader, Ayatollah Ali Khamenei. In retaliation, Iran targeted multiple nations in the Middle East, including Kuwait, Qatar, and Jordan, where U.S. and Israeli military bases are located. Adrian Helfert, chief investment officer of multi-asset strategies at Westwood, commented on the unsettling nature of such geopolitical events and reassured investors that historical patterns suggest an initial market shock is often followed by recovery within three to six months. He emphasized the importance of monitoring energy supply dynamics, especially concerning the Strait of Hormuz, through which approximately one-fifth of the world’s oil passes daily. If it remains open, the broader market impact may be limited; if not, the repercussions could be significant.
In response to the escalation, oil prices surged, with West Texas Intermediate (WTI) crude futures climbing 8.4% to $72.74 per barrel, marking the highest settlement since June. This spike in oil prices propelled the energy sector to become the top performer within the S&P 500 on Monday. Notable energy stocks, such as Marathon Petroleum and ONEOK, saw substantial gains of 5.9% and 4.1%, respectively.
The technology sector also showed resilience, as major tech stocks like Nvidia and Microsoft posted impressive returns of 2.9% and 1.5%. Expectations remained high that these blue-chip stocks could withstand geopolitical risks. Additionally, Apple experienced a slight uptick of 0.2% after unveiling a range of new products at a March event, including the iPhone 17e and iPad Air M4.
Defense stocks largely benefited from the heightened geopolitical tensions, but not all fared well. AeroVironment, a company specializing in unmanned aircraft systems, jumped nearly 20% during early trading but ultimately fell 17.4% after Raymond James downgraded it from a Strong Buy to Underperform. This downgrade prompted concerns about the company’s future revenue, particularly following the U.S. Space Force’s decision to reopen the $1.4 billion Satellite Communications Augmentation Resource program initially awarded to defense contractor BlueHalo, which AeroVironment acquired in late 2024.
In contrast, Applied Optoelectronics was one of the standout winners on Wall Street, surging 21.7%. The company’s stock price has nearly doubled since the previous Thursday after it reported better-than-expected fourth-quarter results. Applied Optoelectronics projected a revenue of $1 billion for the current fiscal year, more than doubling its revenue from 2025. Analyst Ryan Koontz from Needham suggested that the company could significantly benefit from increasing demand for optical transceivers, driven by investments in AI and cloud technology, despite recognizing ongoing execution risks.
In an increasingly volatile market, investors are being reminded of the importance of keeping a focused eye on both geopolitical developments and sector-specific performance to navigate these turbulent financial waters effectively.
