Billionaire Marc Lasry, co-founder of Avenue Capital Group, said the uncertainty surrounding Donald Trump's policies, particularly tariffs, was holding back investors who wanted to take advantage of market opportunities. "When the market doesn't know what to do, that's a problem," Mr. Lasry, 65, told a conference on credit opportunities at New York University on Friday. "An economy is not immune in a situation like this, and that just slows everything down, potentially sending the economy into recession." (Jin Ten)
