GSK Hedge Radar

Neutral

Full Hedge Radar

Neither score is at an extreme today. Neither axis is a forecast — this is where GSK sits on protection cost vs. fragility today.

Protection is priced in the cheap band (2.59) — implied vol sits in the 10th percentile of its own past year, and downside puts carry 3.4 IV points more than at-the-money, measured against this name's own rolling 22-trading-day realized moves (482 overlapping windows). Fragility reads neutral (4.44): it is trading 3% above its hedge wall on a wall graded MEDIUM for reliability, and its realized-vol regime is stable.
