Changes in analysts' earnings estimates: agreement, magnitude, upside and surprise. Stocks are sorted into five groups from #1 Strong Buy to #5 Strong Sell.

No. MoonshotScore V2 reads no news-sentiment or analyst data; it rates eligible companies on five pillars against their sector peers, as set out on the methodology page.

Evidence & Sources

  • Figures come from Financial Modeling Prep (FMP). If FMP has no figure for a ticker, a price or fundamental may come from a Yahoo Finance fallback, or a price from an Alpaca fallback. SEC EDGAR is used only for filing links and company identity details (legal name, address), never for figures.
  • MoonshotScore V2 rates eligible US-listed companies from 0 to 100 against their sector peers on five pillars: Business Quality (weight 26), Financial Safety (weight 20), Valuation (weight 18), Growth Durability (weight 16) and Momentum (weight 12). It reads no news-sentiment or analyst data, and it is not a probability of future returns.
  • Definitions follow standard investing terminology, with key terms explained inline in plain language where useful.
  • Each price is the last quote we recorded, shown with the trading session it belongs to. Pages are served from a cache, so the copy you are reading can lag that quote. Each quote is a provider snapshot, not an exchange feed.
  • This page is educational and does not constitute investment advice.
  • All analysis is generated by AI models and should be verified with independent research.
