I was actually up 13% on ENB a Canadian pipeline company. My gain is cut in half because I doubled up on shares. I'm long on everything but RHT which is a cash payout.
You’ll probably make 10% on this trade. But the is risk of losing more than that if the transaction doesn’t close for some reason is real. That’s not free money.
The risk is obviously lower now than it was the day after the acquisition was announced. And the upside is also lower now. Less than 4%, for a closing which is not expected until the second semester of 2019 as far as I understand.
