Why this analysis is different

  • A sector-relative MoonshotScore — five pillars (business quality, financial safety, valuation, growth durability, momentum) re-ranked nightly against the full universe of US-listed common stocks.
  • 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.
