Billionaire investor George Soros recently directed a series of "big, bearish investments" after a long break from trading, the Wall Street Journal reported, citing people close to the matter.
Soros Fund Management, which manages around $30 billion for the Soros family, sold stocks and bought gold and shares in gold miners, amid a "gloomier" view of the global economic outlook and the potential for large market moves, the WSJ reported.
In an interview by email with the news outlet, Soros noted particular concerns over capital flight from China, as well as how the mainland's political milieu may prevent lasting reform.
Soros was also concerned that a combination of the migration crisis, Greek challenges and the U.K.'s potential exit could lead to the European Union's collapse, the WSJ report said.
