Since Donald Trump's inauguration, U.S. stock markets have experienced substantial losses, with a total decline of approximately $10 trillion. Globally, stock markets have fallen by up to 20%. Specific indices reflect these downturns: the Dow Jones has decreased by 12.7%, the S&P 500 by 15.6%, and the Nasdaq by 20.5%. The losses have been particularly pronounced following Trump's recent tariff announcement on April 2, which contributed to a collective loss of $7.7 trillion in U.S. stocks.
