I was trying to make a point to MSwanson that his statement was absurd. I took his comment to mean that Swift was unusual in that its stock price rising and falling due to the commodity price was something unique to Swift. The more important part of my comment in the last part about Swift's ability to recover.
I would imagine that the price charts of most energy companies would coincide with the up and down of the oil and gas prices. It is how the industry works. It certainly isn't unique to Swift. I'm not at all sure that Swift will be able to pull themselves back up this time. They don't have Earl Swift anymore, plus they have lost most of their longtime employees either to retirement, new jobs or lay-offs. The foundation that grew this company is no longer there.
