OK, now you've got my attention. This is the kind of player that really could manipulate TSLA. They have been making huge swings in the amount of TSLA they've owned over the years, and have very large option interests, including a net put option value of almost 2 billion. It would definitely be worth shining a spotlight on their trading activities.
Here's some info I saw reported about their positions in November (a few month before what was reported in the current filing):
