In a day marked by significant gains in major U.S. stock indexes, the S&P 500 and Nasdaq both reached record highs, buoyed by the strong performance of tech giant Nvidia, which closed with a market valuation of $4 trillion. The rally was further supported by optimistic earnings forecasts from Delta Air Lines, which also contributed to the rise in airline stocks. Despite some volatility and concerns over tariff implications, investors remain undeterred, pushing stock markets to new heights. This bullish sentiment was echoed across global markets, with many Asian shares reflecting the robust performance of Wall Street.
