/**
 * Highest composite short-squeeze scores — a peer-relative 0-100 rank: a weighted mean of six factor percentiles (short interest % of shares 30%, days to cover 20%, price vs trailing VWAP 15%, short-volume trend 15%, short-interest change 10%, fails-to-deliver pressure 10%) plus catalyst boosts for an unusual price spike, volume surge, or a scheduled earnings call within a few weekdays (+10 each, capped at +20, clamped to 100), highest score first. Untradeable micro-caps dominate the raw board; pass minMarketCap and/or minDollarVolume to keep only names clearing your liquidity bar (scores stay peer-relative to the full universe).
