Nonsense... of COURSE it has a LOT to do with oil and gas. It was the downturn in sales and payments in Russia that started the downhill slide and and now the rest of the oil industry world wide keeps it going downhill. Not saying I love the management, but you can NOT say the price of oil and gas has no part in this. Crummy management or not, they were doing pretty well for a while and the market thought so as well.
I wrestled with reality for years, Doctor, and I'm happy to state, I finally won out over it. (Jimmy Stewart in "Harvey" 1950)
