Positions as of Jun 30, 2018, from Magnetar Financial LLC's 13F filing with the SEC. A 13F lists a manager's US-listed stocks and options at a quarter end and is filed up to 45 days later, so the fund may hold something else today. It leaves out short positions, cash and holdings outside the US.

Price is a stock's reported value over its shares at the quarter end.
