Component signals

Signal	Value	Source
Days to cover	5.78	short interest →
Shares short	5,300,015	FINRA
Avg short volume %	51.42%	short volume →
Peak fails-to-deliver	18,560	FTD →

How this score works. A transparent 0-100 heuristic: 40 points for days-to-cover (scaled to 15), 30 for average short-volume %, 30 for fails-to-deliver magnitude. It combines three independent short-pressure signals into one view — it is not a prediction or investment advice, and FINRA short volume includes market-maker hedging.
