Why this analysis is different

  • A 9-signal quantitative MoonshotScore built from filings, insider activity, and market data — computed from the numbers, not from opinion.
  • An AI Council read across up to eight perspectives — value, macro, quantitative, and momentum lenses — that shows where they disagree instead of averaging the tension away.
  • Figures come straight from FMP and Yahoo Finance filings data. The AI writes the narrative around the numbers — it never edits the numbers.
