Clinton Supporter George Soros Lost $1 Billion During The 'Trump Rally'

Soros took on a more direct role at his family office mid-last year and made a series of bearish bets. WSJ's report noted that he became incrementally bearish after President-elect Donald Trump won the U.S. presidential election.

WSJ, citing its sources, noted that Soros acknowledged he was on the wrong side of the trade and closed many positions late last year, which incurred a loss of around $1 billion.

On the other hand, the broader portfolio held by Soros' firm posted profits both before and after the election, partly due to its exposure to the financial and industrial sector. As such, the Soros Fund Management finished 2016 higher by around 5 percent.

Soros trades a portion of Soros Fund's cash, but it appears his role will be limited once again when his firm fills the currently vacant chief investment officer position.

Soros' losses contrast those of notable investor Stanley Druckenmiller, Soros' former deputy in the 1990s.

WSJ noted that Druckenmiller profited from the U.S. election. He felt that if Clinton were to emerge victorious in the election, then the stock market would initially rally but then reverse course and drop. He also felt that if Trump were to win the election, stocks would initially tumble and then erase its losses and move higher.

It turns out Druckenmiller was right. U.S. equity futures immediately plunged during the late-night futures trading session when it became apparent Trump would emerge victorious.

Druckenmiller's vision paid off as his family office, Duquesne Family Office, ended 2016 higher by more than 10 percent.
