There's nothing boring about George Soros' investing -- at least not for those who follow his stock picks each quarter.

The Hungarian-born investor and philanthropist has amassed a more than $20 billion fortune. Over the years, he has made enormous plays in bonds, stocks and currencies. A 1992 short sale on the British pound earned him the title of "The Man Who Broke the Bank of England."

As exciting as Soros' investing career may sound, he believes it should be just the opposite. "If investing is entertaining, if you're having fun, you're probably not making any money," he once said. "Good investing is boring."

Soros may not be amused by his investment moves, but there are many people out there who are.

Although he stepped back from managing clients' money in 2011 -- and declared his retirement again in 2015, saying "this time it is final" -- Soros Fund Management is still alive and kicking. And Soros, who is still listed as the firm's investment manager in public filings, is very likely still involved.

His latest 13F filing, corresponding to June 30, reflects $4.7 billion invested across 173 holdings.

A number of the positions listed are recently initiated ones. Here are 10 of Soros' biggest new buys from the second quarter of 2016.
