STO is helped by the krone getting stronger. STL.OL is hurt. I had it backwards.
So if you think you want the currency hedge built into your oil stock it is a good long term buy. I do not know jack ___ about which way currencies will go, but there are a boat load of dollars it seems. I bought STO today feeling like a small percentage is good. It still has the dividend. Also I think the earnings will be astronomical due to the gain on sales of oil in the ground. The thing the Norwegian government does that hurts STO is putting too many krones into circulation. So if that is detectable then traders will shy from the krone. I have no clue on the currency trading as the governments are the big traders.
