We skeptics said that investors would at some point realize that shale oil was a long-term money loser. A former industry CEO did the math and calculated the damage as minus 80 percent for investors in the industry as a whole since 2008. Lately, investors seem to be reacting to facts rather than the hype.
Will shale oil rise again from the dead as it did after the 2014-2016 price decline? That will happen only if two things occur: 1) The oil price rises significantly and 2) investors have a serious bout of amnesia.
