CUE WORLD’S SMALLEST VIOLIN: Billionaire George Soros Lost Nearly $1 Billion in Weeks After Trump Election.

Last year, Mr. Soros returned to trading at Soros Fund Management LLC, which manages about $30 billion for Mr. Soros and his family. Mr. Soros was lured back by the opportunities to profit from what he saw as coming economic troubles.

Mr. Soros was cautious about the market going into November and became more bearish immediately after Mr. Trump’s election, according to people close to the matter. The stance proved a mistake—the stock market has rallied on expectations that Mr. Trump’s policies will boost corporate earnings and the overall economy.

As a result, some of Mr. Soros’s trading positions incurred losses approaching $1 billion, the people say. Mr. Soros adjusted his positions and exited many of his bearish bets late last year, avoiding further losses, the people added.

Maybe he got tired of all the winning.
