Quote from Maverick74:
How do you do you know he wasn't spreading that trade against something else? That trade could actually have been a long trade you know.
As you said, you will never know. One thing that I am sure is that it is not his only position in his big portfolio. He should have some more long/ short positions.
. If you really don't believe that I am long, I can send PM you my position in TZA.
