VOO Hedge Radar

No action needed

Full Hedge Radar

Fragility reads low; protection is priced cheap. Neither axis is a forecast — this is where VOO sits on protection cost vs. fragility today.

Protection is priced in the cheap band (2.54) — near-dated vol is priced 31% below far-dated, and implied vol sits in the 6th percentile of its own past year, measured against this name's own rolling 19-trading-day realized moves (485 overlapping windows). Fragility reads resilient (2.5): it is trading 12% above its hedge wall on a wall graded HIGH for reliability, and its realized-vol regime is stable.
