Ray Dalio, the billionaire founder of hedge fund Bridgewater Associates, said that he's increasingly nervous about President Trump's antagonistic stance towards China. "I'm worried and forced to look harder at the question of where Donald Trump is leading us. What is his real agenda?," Dalio wrote Monday in a LinkedIn post titled "More on Trade and Other Wars." "Right now, I don't think it's clear to anyone, including some of the people closest to Donald Trump, what exactly his strategic objectives are," he added. Bridgewater Associates is the largest hedge fund in the world, with assets of $160 billion.
