The recent speech by Federal Reserve Chairman Powell, characterized by a dovish tone, led to a significant surge on Friday. The S&P 500 and Dow Jones indices reached record highs, accompanied by multiple stocks showing favorable buy signals. Market attention now turns to Nvidia's upcoming earnings report, as investors assess the impact of Powell's influence on the market's rally. Dow Jones futures have since experienced a decline, setting the stage for Nvidia's performance to serve as the next major test for the market following the Powell-led upturn.
