Nov 1, 2026 · Score 67 · Type A — Value-style analysis Used for established, cash-generative companies — weighs earnings power, valuation against the company's own history and peers, and margin of safety. Full methodology →
Current PriceThe market price around the time this report was written — not a live quote. The market has moved since; check a current price before acting.Methodology → $235.99
Buy ZoneThe large figure is the midpoint of the suggested buy range shown in parentheses. $180.00 ($175.00–$185.00)
Price TargetOur estimated fair value. For richly valued stocks it can sit below the current price — see Methodology.Methodology → $210.00
Expected Return
  • Target relative to the Current Price ((Target − Current) ÷ Current). Since that price is from the report date, your actual return will differ.
  • A negative Expected Return means the Price Target is below the report-date Current Price. This can occur even with a Buy or Strong Buy recommendation because recommendations follow a fixed mapping from the overall investment score, which combines business assessment, valuation and risk. This is a limitation of our score-based framework: a favorable recommendation does not always imply an attractive entry price. Consider the Price Target, Buy Zone and valuation analysis together.
