Statistical, not machine-learning: a random-walk (no assumed drift) volatility model built from this ticker's own realized price history, plus a purely descriptive moving-average trend read. Illustrative only — not a price target and not financial advice. The bear and bull cases sit one standard deviation (1σ) below and above today's price, a range that covers about 68% of the outcomes the model treats as plausible, not a 68% chance of either case. Annualized volatility used: 35.9%, blended from this ticker's own 3-month and 1-year realized price history. Base case is deliberately flat — this quantifies a possible range, not a directional prediction. See the full model, including wider (≈95%) bands →
