Time runs left to right, Dec 2016 to Sep 2026. Crude oil pools below the seam and US share prices hang above it. Each edge pulls back from the seam by that month’s percentage below its highest monthly value since December 2016, on one scale, and never curves past a month’s value. The sheen is decoration.
