A new report from BlackRock Investment Institute suggests that the U.S. stock market may experience short-term volatility due to policy uncertainty. While this could lead to some pressure, strategists remain optimistic about the long-term prospects of the market. Favorable factors include progress in AI development, strong corporate earnings, and a robust US economy. The report points out that policy uncertainty could potentially slow economic growth and impact stock market performance in the near future. However, there is hope for a regain of global leadership within the U.S. stock market. Despite this, investors should expect continued volatility as risk assets fluctuate widely, with price swings becoming sharp.
