Wall Street’s Nasdaq hits all-time high as AI frenzy gathers pace

Wall Street’s Nasdaq stock exchange has hit an all-time high, shrugging off concerns about AI safety risks, sky-high tech valuations and the energy shock caused by the United States’ war on Iran. The Nasdaq Composite index, which is dominated by US tech giants such as Nvidia, Apple and Microsoft, rose 0.45 percent on Tuesday, taking its gains to date this year to more than 17 percent. The Nasdaq 100, a narrower index that tracks 100 top companies, jumped 0.82 percent. The S&P 500, the most popular measure of the overall US stock market, closed essentially flat. Monolithic Power Systems, a Florida-based manufacturer of power circuits, and Canadian e-commerce company Shopify led the gains, surging 8.1 percent and 7.1 percent, respectively.
