With OPEC and Russia negotiations in play this week, I have been getting a lot of emails from investors about oil. Many have strong opinions. Some think oil CLN7, -0.56>#/span### is going to go down to $25 a barrel. Others think it is going to go up to between $75 and $100. Given my history of providing high-conviction opinions that have often been contrary, both bullish and bearish oil investors seem to want me to agree with their arguments. Take a look at the annotated long-term chart of oil. The chart is of a continuous futures contract, and for the sake of accuracy, I have not updated it. In terms of spot oil prices, I was steadfastly bearish on oil and calling for short-selling oil when it was around $108 per barrel. I stayed bearish all the way down to $26, before turning neutral at $29. Now the good news is that arguments on both sides are solid. The bad news is that for the short- to medium-term, I cannot agree with either side. Let me explain.via
