US Wall Street’s main indices opened higher on Wednesday, recovering after recent volatility as investors weighed concerns surrounding the AI trade and uncertainty over tariffs ahead of Nvidia’s earnings later in the day (local time).The Dow Jones Industrial Average rose 183.1 points, or 0.37%, to 49,357.63 at the open. The S&P 500 gained 25.1 points, or 0.36%, to 6,915.15, while the Nasdaq Composite advanced 141.3 points, or 0.62%, to 23,005.008.Nvidia remains at the centre of the AI-driven market narrative, with its chips playing a pivotal role in the ongoing surge in artificial intelligence investments. The company has become one of the most influential stocks on Wall Street.Analysts are projecting another strong earnings performance, with Nvidia’s profit expected to jump nearly 70 per cent year-on-year to $37.52 billion. Such a result would translate into daily earnings exceeding $400 million during the three months through January 25.Nvidia’s earnings reports have increasingly served as a barometer for broader market trends, given the company’s size and AI’s outsized influence on equities. In recent years, enthusiasm around AI helped propel markets to repeated record highs, driven by expectations of productivity gains and improved corporate profitability.However, investor concerns have intensified over the sustainability of heavy AI-related spending. Market participants are closely watching whether major technology companies such as Alphabet and Amazon can generate sufficient returns on their substantial investments in AI infrastructure and chips. Any slowdown in capital expenditure could directly impact Nvidia.Investors have also begun reassessing sectors perceived as vulnerable to AI-led disruption, triggering sharp sell-offs across industries ranging from software to logistics and legal services.“While those concerns are real, we believe investors would be wise to balance them out with offsetting trends that may be underappreciated in the current wall of worry headline cycle,” said Darrell Cronk, Chief Investment Officer for Wealth & Investment Management at Wells Fargo.One such offsetting trend has been the steady growth in corporate earnings reported by large US companies, which has supported segments of the market previously overshadowed by AI-focused stocks, particularly smaller firms.Shares of Cava Group surged 18.6 per cent after the Mediterranean restaurant chain posted stronger-than-expected profit and revenue. The company also reported annual revenue exceeding $1 billion for the first time, marking a 22.5 per cent increase from a year earlier.Similarly, Axon Enterprise jumped 16.5 per cent following better-than-expected earnings, aided by demand for its Tasers, body cameras, and AI-powered solutions.The gains helped counterbalance weakness in First Solar, whose shares fell 14.2 per cent after reporting profit below market expectations.
