What problem does it solve?

Helps you interpret institutional “smart money” behavior by turning SEC 13F ownership and holder-change patterns into an actionable investment signal.

Core Features & Use Cases

  • Institutional ownership snapshot & trend (4 quarters): Summarizes total institutional ownership, number of holders, shares/value held, and ownership changes to infer bullish/neutral/bearish sentiment.
  • Top holders, position changes, and concentration: Identifies top holders, quarter-over-quarter adds/reductions/eliminations, and evaluates how concentrated ownership is (including turnover and stability).
  • Smart money and activist lens: Highlights notable investors’ buys/sells, surfaces activist/strategic holders, and connects ownership activity to potential catalysts and performance.
