(Reuters) -The dramatic shift in U.S. domestic and foreign policy since President Donald Trump returned to the White House on January 20 has sent shockwaves across global financial markets. Trump's multi-front trade war and constant flip-flops on tariffs have upended supply chains, clouded business outlooks and stoked fears of a recession in the U.S. The S&P 500 has lost nearly 8% since his January 20 inauguration. Data analytics provider Palantir, which works with the Department of Homeland Security, has surged nearly 60% since Trump came into power as the Department of Defense prioritizes a new software acquisition effort to enhance the U.S. military.
