RE:the conflict in europe right now First of all the possibility of war is extremely low, secondly even if a war starts which I hope not regardless of oil supply shortage there will be a huge sell off in the stock market including oil stocks, in that case people keep cash. I would never invest in something due to a war or conflict. Investment in oil stocks should be based on demand and supply in the normal world situation and the company's management and performance.
in my opinion the long term oil market is bright and bull due to 2 reasons, one demand is increasing and second OPEC+ is in control and needs $80+ oil because they rely on oil revenue to run their countries, for sure there will be up and down fluctuations. The short term market depends on overall market reaction, let's see if the market will rebound this week or the sell off continues.
Again all my opinion.
