Historically, Trump's protectionist policies and tariffs have led to increased market volatility, but in this case, the specific focus on steel and aluminum may boost the stock prices of companies in these industries. The exemptions for certain countries, such as the UK, may also impact trade relationships and global market dynamics. The increased tariffs could lead to higher prices for steel and aluminum, potentially affecting industries that rely heavily on these materials, such as construction and automotive. However, the overall impact on the stock market is likely to be positive, at least in the short term, as investors react to the perceived benefits of protectionist policies for US manufacturers. The market sentiment score of 65 reflects the potential for increased stock prices in the steel and aluminum industries, but also acknowledges the potential for increased volatility and uncertainty in the broader market.
