Bridgewater: Expects Strong Economic rise in the U.S. During Trump's Term Bridgewater Associates co-chief investment officer Karen Karniol-Tambour said on Tuesday that holding U.S. stocks is a "good thing" and she expects a strong rise in the economy during President Trump's term. Karniol-Tambour said that the prospect of a rise in the U.S. economy has driven the stock market higher, despite the 10-year U.S. bond yields reaching a four-month high after Trump's victory in the presidential election on November 5. She said, "We may still have room for rise, even in the case of tariff imposition and there are many unknown factors." Since Trump won the election, the S&P 500 index has risen nearly 5%.
