President Warren? President Sanders? Even a President Bloomberg, who thinks California is the model for the rest of the country, would add risk to stock and bond markets. Some of Wall Street’s biggest investors have already raised the alarm that stocks could see a big sell-off if markets start to believe that Sanders could prove a meaningful political threat to President Donald Trump. Bond investor Gundlach said that the biggest risk to the market in 2020 was the possibility of Sanders becoming president. Longtime hedge fund manager Stanley Druckenmiller said something similar last summer, warning that stocks could plummet if Sanders is elected president. “If Bernie Sanders became president, I think stock prices should be 30% to 40% lower than they are now,” he said in June. “The good news is we’d all be much more equal because everybody would be poorer but the rich would have lost a lot more wealth than the poor would have,” Druckenmiller said.
