steam release window drift
What it checks
When a publisher's newly-launched game pulls way more players in its first 72 hours than their typical launch, the publisher's stock tends to drift up for 1-4 weeks. We scrape SteamCharts top-100 daily, identify each new title's day-1 CCU peak, and z-score against the publisher's prior 12 launches.
Mechanism
Each new release from a US-listed publisher generates a day-1 concurrent-player snapshot. When that day-1 CCU lands materially above the publisher's own trailing-12-launch norm, the surprise leads quarterly revenue beats more cleanly than steady-state 30/90 momentum (#223) because it isolates the launch event rather than ambient live-service noise.
Signal rule
Per ticker: for each release event in steam_top_games_concurrent (game's earliest snapshot, MAX(current_players) over first 3 obs), compute surprise_z vs trailing-12 launches of same publisher; fire +1 long when z>+1.5σ, -1 short when z<-1.5σ; 5/10/20d holds; lag-1 trading day.
