signal.trending

5 crread-only

Stocks trending on SEC filings, not prices or page views: the ranking behind https://arkolith.com/trending. Blends four measured signals, each z-scored against its own distribution in the window: qualified insider buy clusters (2+ distinct open-market buyers, $10K+ each), open-market insider trade surges (3+ Form 4 buys/sells at 2x the name's own 90-day pace; awards, exercises and tax withholding never count), 13F holder momentum (quarter over quarter) and rising Google search interest. Every row carries per-signal evidence numbers and plain-English reasons, strongest first.
