By Jack Hough My proprietary oil model predicts less price volatility ahead. OK, there’s no model, but a chart of spot Texas crude still makes me shake my J.R. Ewing Stetson in disbelief at how nuts energy trading got over the past five years. OK, there’s no Stetson, either. Early in the pandemic, near the expiration for May 2020 futures contracts, oil briefly sold for negative $37 per barrel, because highways were empty, storage tanks were stuffed, and there was nowhere to receive the stuff. In summer 2022, with demand restored, and Russia well into its Ukraine invasion, prices topped $120. More recently, Texas crude sold for $77, down from $90 at the end of September, but up from $72 since the start of this year. The futures curve implies that prices will fall from the high to low $70s from now through 2027. Jason Gabelman, an oil stock analyst
