Analyst: Multiple risks quickly dissipate, U.S. stocks regain optimism.

Independent analyst Ed Yardeni pointed out that the main factor driving the stock market to repeatedly hit new highs is the significant decrease in economic uncertainty. It now appears that the tariff policy will be more moderate than expected in April of this year, and the tariffs implemented so far have not had a significant impact on the economy, as evidenced by the continued strength in the labor market. In addition, analysts have stopped lowering their earnings forecasts for the companies in the S&P 500 index. "Between February 19 and April 8, uncertainty in various aspects rapidly increased, triggering a market correction; but since then, these risks have also rapidly diminished."
