Wall Street rises, boosted by microchip stocks amid tech earnings focus

Wall Street indices concluded Tuesday with gains, as a robust recovery in microchip stocks redirected investor attention from Middle Eastern geopolitical tensions and trade disputes over tariffs.

Markets concentrated on the forthcoming earnings announcements from major technology firms, seeking indicators for the trajectory of artificial intelligence-related trade. The rebound in recently pressured microchip stocks provided substantial support to the main U.S. indices. The Philadelphia SE Semiconductor index recorded a strong advance for the second consecutive session, following a decline of over 20% from its late June peak.

"Investors are returning to microchip stocks ahead of earnings, fearing they might miss potential earnings beats and outlook upgrades (FOMO), while no longer holding as many shares as before the correction," said Lindsay Bell, chief investment strategist at 248 Ventures in Charlotte, North Carolina. However, Bell cautioned that sharp pre-earnings rallies make continued upward movement post-results more challenging. "The numbers will be very good, but the stocks are also priced to perfection," she added.

The semiconductor index had previously fallen due to concerns over high valuations and significant investment plans in AI. Despite this, it remains up nearly 75% year-to-date. Preliminary data showed the S&P 500 rising 0.86%, the Nasdaq Composite gaining 1.26%, and the Dow Jones Industrial Average increasing by 0.74%.

Technology sector stocks led the gains among the 11 major index sectors, while consumer staples stocks declined. Investors appeared to disregard President Donald Trump's announcement of 50% tariffs on a wide range of Canadian imports. They also remained unfazed by geopolitical developments, even as oil prices closed 2% higher, reaching five-week highs. The movement of two Saudi crude oil tankers in the Red Sea, prompted by Houthi threats, did not significantly impact market sentiment. Bell noted that investors perceive the conflict as temporary, considering both oil price pressures on Trump and the approaching midterm elections.
