In a roller-coaster week for Wall Street, big tech stocks propelled the S&P 500 to notch its longest winning streak since January, closing higher for four consecutive days with a weekly gain of 4%. As earnings reports from key players like Alphabet and Tesla surpassed expectations, hopes for easing trade tensions further supported the bounce back. Despite some volatility, the markets showed resilience, buoyed by optimism surrounding U.S.-China trade negotiations and positive economic indicators. The Dow, Nasdaq, and S&P all experienced significant gains, with tech shares leading the charge. Investors are closely watching developments on tariffs and further earnings reports, as mixed signals from the Trump administration continue to create uncertainty.
