Tech stocks, like Apple, Sony, and Microsoft, shot up quickly following Trump's announcement, with Tesla rising particularly fast. As of this writing, Tesla stock was up 22.69 percent for the day. Meanwhile, Intel gained more than 17 percent; Nvidia was up by over 15 percent; and Meta, Amazon, Alphabet, and more stocks were spiking as well.

President Trump's unpredictable trade policies have pushed stock volatility up to its highest level in years, creating substantial uncertainty and, some say, opportunity on Wall Street.
