Somebody always knows in advance Last week, the volume on ENB put options was over 20,000 contracts which equates to 2 million shares.
I bought a few after 4 down days which was too early as today will make 6 down days in a row.
If I had to guess, I would say that the Put Option purchase was made with the full knowledge that there would be a downward push on the share price of ENB. Collusion is very hard to prove, especially when nobody is looking.
