Bullish Case: ULTA has run +15.7% in a month to $635 on momentum that options markets partially endorse: bullish risk is 48% above bearish, calls outvolume puts 7%, and Helium's AI forecast is +5.06%. The term structure is flat (~34-37% beyond December) with no long-dated downside regime priced, implying the market sees recent gains as durable, not event-driven. Holiday comps, Cécred/Rare Beauty rollouts, and salon AOV growth can extend the move toward $660-700.

Bearish Case: A 22.7% annual gain into a P/B of 10.4 leaves no error margin; any comp deceleration or margin miss risks a violent reprice. December 5 IV jumps to ~36-44% (Helium trace shows a December hump at 35.6/43.7 vs 25-26% adjacent weeks), flagging Q3 earnings as a binary event. Six Flock license-plate-reader class actions plus a +5% Helium forecast with -0.1 historical correlation (a contrarian signal) both argue against chasing strength here.

Potential Outcomes: 1. Post-earnings digestion (35%): Q3 beats modestly; $610-665 range; December IV hump compresses after Dec 3-4 print.
2. Momentum extension (25%): holiday comps + upgrades push $665-700; falsified if December IV expands instead of collapsing.
3. Pullback (25%): profit-taking/litigation headlines to $570-610; watch Dec IV re-steepen.
4. Sharp miss (<15%): guidance or consumer shock below $570; far-put IV (Jun-27 ~40%) reprices upward.
