Historically, Trump's statements on immigration have led to increased market volatility, particularly in industries that rely heavily on immigrant labor. The introduction of a self-deportation program may lead to labor shortages in sectors such as agriculture, construction, and hospitality, potentially driving up costs and reducing profit margins. Furthermore, the uncertainty surrounding the program's implementation and potential legal challenges may deter investors and weigh on market sentiment. The technology and healthcare sectors may be less affected, but the overall impact on the stock market is likely to be negative, at least in the short term. Regulatory implications and international trade implications may also be affected, as countries with significant immigrant populations in the US may respond with retaliatory measures. Market confidence is likely to be shaken, leading to increased volatility and a potential decline in stock prices.
