George Soros had a successful Q2, according to a recent report by Seeking Alpha which tracks the billionaire's 13F filings. According to the report, Soros saw the assets for his Soros Fund Management increase from $4.96 billion at the beginning of the quarter to $5.62 billion by the end, an increase of more than $600 million in a three-month span. Among the new positions that Soros bought into over the period in question, Altaba, Inc. (AABA) was one of his biggest moves.

Soros Buys AABA, Invests in Puts in ETFs

Soros bought up a substantial position in Altaba, Inc., the investment company which was generated when Verizon purchased Yahoo!, Inc.'s internet business. The position represents about 2.5% of Soros' portfolio, meaning that it's worth somewhere in the area of $140 million.

There were other new stakes that Soros adopted over the course of the second quarter. Notably, he bought up a massive position in puts and calls. The billionaire bought puts in PowerShares QQQ (QQQ) and calls in SPDR S&P 500 (SPY). The puts in QQQ occupy about 18% of Soros' short positions, making them the largest 13F position. The position in SPY is roughly 1%, though it is also offset by a much larger short position in SPY puts as well.

Soros increased his existing positions in TiVo Corporation (TIVO), Time Warner (TWX) and Mondelez (MDLZ), among other smaller holdings.

Numerous Stake Disposals

Soros decided to sell off a number of his positions over the course of the second quarter, too. In total, the billionaire moved form 260 total positions in his portfolio to just 203 by the end of the quarter, so he eliminated a net 57 positions in those three months. Among these was Adecoagro S.A. (AGRO), which had occupied about 5% of Soros' U.S. long portfolio as recently as the last quarter of 2015. In the meantime, he has periodically sold off portions of the stake. Soros also sold out of Hewlett Packard Enterprise (HPE) shares. It represented just 0.6% of his portfolio as recently as the last quarter of 2016.

Soros also sold out of Symantec Corporation (SYMC) after he had nearly tripled his position in the first quarter of the year. Finally, he eliminated a number of smaller positions, including C&J Energy Services (CJ), Grupo Supervielle (SUPV), Netflix Inc. (NFLX), and Oracle Corp. (ORCL) calls.

As in every round of 13F filings, it's important for investors to keep in mind that money managers like George Soros maintain portfolios with other holdings besides the ones that are shown in these reports. 13Fs offer a glimpse into the investment strategies of top investors, but they do not provide a complete picture.
