Eight Hours, One Sentence: Anatomy of a Geopolitical Gap-and-Fade

Brent gapped nearly 4% overnight to break $90 and S&P futures were down about 1% at 4 a.m. By the opening bell, crude had pared to $88 and stocks were higher.

The mechanics are knowable. The variance is brutal. Both deserve to be stated plainly.
