Look for a 'pop' on ENB on Monday as many ETFs will have to boost their position with the increase in ENB market cap once the SE deal closes. 

That is also a large part of the weakness today as these same ETFs have to raise cash to buy ENB on Monday. 

BTW, as long as ENB continues to raise their dividend by 10-12% per year thru 2024, I don't care what the stock price is. The annual payout will be 4X what it was when I first purchased it in 2010, (Split adjusted of course) and double what it is today.
