The US stock market has seen significant gains as major indices, including the Dow and S&P 500, hit record highs, buoyed by impressive earnings reports from large banks like JPMorgan and Wells Fargo. The Dow surged over 400 points, while the S&P 500 closed above the 5,800 mark for the first time ever. Market analysts attribute this rally to a positive reaction to recent economic indicators and strong quarterly performances from financial institutions, indicating a growing confidence in the economy. Despite some losses in other sectors, such as a drop in Tesla shares following its robotaxi event, the overall sentiment remains optimistic as investors celebrate a fifth consecutive week of gains.
