I wonder what is causing it? Long term I think they could be granted an LNG export permit and the Stock would move several points on that however I have not heard of any movement in this area. I'm thinking of taking profits in my IRA account and then buy back on the inevitable "dip."
So far Chererie has been the only one granted a permit to export.
Having said that, there is a meeting scheduled between Japan's FM (?) Abe, and Obama for a 'free trade agreement' on the export of LNG. Japan is currently paying about $16.50 per measure of LNG and currently has tentative contracts with D for LNG export.
I'm also watching D's 'Insider Trading', since the 'notable' share purchases back about the end of 2010, and for a few months into 2011 (timeline ??) and I've not seen a major selloff from these guys since that time. Their investments (I think) were based solely on the LNG side.
D investments in the LNG Industry leaves it in an excellent position to move forward as an Enery/Electric Utility Company.
As for "inevitable dips" ?, I don't think it will be anything major other than normal ups and downs, and expect a fairly steady promise for it's future growth .. specially on the LNG side.
