Box Office Opening Drift
In plain terms
When a studio's movie opens way above or way below its recent average, the studio's stock drifts in that direction for about two weeks. We scrape The-Numbers daily box-office, compute the per-distributor surprise z-score, and trade the +/-1.5 SD threshold on Monday open.
How it works
Opening-weekend grosses are still the single most-watched data point for the major US-listed studios. A weekend-gross surprise vs the rolling-12-release per-distributor baseline drives a measurable Monday-open drift in the distributor's equity that persists ~10 trading days before being fully absorbed.
