Soros Fund Management held 2,472,188 shares in Overstock at the end of the fourth quarter of 2017, making it the third-largest shareholder, according to regulatory filings released late Wednesday.
These were worth $157.97 million at the end of the last trading day in December and $146.72 million at the close of trade Wednesday.
Shares of Overstock have risen over 200 percent in the last year after the company announced plans to jump into the digital coin-trading business in September. Overstock's majority-owned subsidiary tZero teamed up with two financial services companies, RenGen and Argon, to create what they call a "distributed ledger platform for capital markets."
Overstock is an e-commerce firm focused on home goods and clothes. Chief Executive Patrick Byrne has been bullish on bitcoin, which it has accepted as payment since 2014, and the technology that underpins it, known as blockchain.
The Securities and Exchange Commission (SEC) filings do not give any commentary behind what stocks funds buy and sell.
Soros spoke publicly about the cryptocurrency space in January at the World Economic Forum (WEF) in Davos, Switzerland. The billionaire investor said that blockchain technology could be put to "positive use," but cryptocurrency is a "typical bubble."
The SEC filings also show other moves made by Soros Fund Management. It completely sold the relatively small holding of 10,000 shares in Amazon it owned.
It dumped 109,451 shares of Facebook, which were worth $19.3 million at the end of the December quarter. In the third quarter of 2017, Soros' fund sold 367,262 Facebook shares. The investor has been critical of internet companies, particularly Facebook and Google. At WEF, he called the companies a "menace" and said that it was "only a matter of time before the global dominance of the U.S. IT monopolies is broken."
Soros' fund did buy 1,600 shares of Google parent Alphabet in the three months to December, however. The fund's total holding is a small 4,600 shares.
All three companies had strong quarters at the end of 2017. Netflix added more subscribers than Wall Street had expected, Twitter reported its first ever net profit, while Snap reported growing users and revenues.
Meanwhile, Soros Fund Management sold 45,300 shares of Microsoft.
