How to read the ZBU6 implied-range chart

The shaded range above shows the one-standard-deviation implied price band at each listed expiration, derived from ATM implied volatility scaled to days-to-expiration. Under lognormal assumptions, roughly 68% of outcomes fall inside that band; 95% fall inside ±2σ; 99.7% inside ±3σ. The empirical equity-return distribution has fatter tails than lognormal, so true tail-outcome frequency is moderately higher than these closed-form numbers suggest.

ZBU6 expected move and event pricing

Expected move widens with √time: a 5% 30-day move corresponds to roughly a 2.5% 7.5-day move and a 10% 120-day move.

Sizing ZBU6 structures to the expected move

Iron condors with wings at ±1σ collect the modal-outcome premium; ±1.5σ widens probability of inside-range to ~87% but cuts collected premium roughly in half. Strangles do the inverse trade - they pay against the same lognormal distribution, profiting when realized exceeds implied. Calendar spreads bet on the slope of the term structure rather than the level. ZBU6 put/call volume ratio currently at 0.58 indicates speculative call flow dominates - look for upside-skewed sentiment. The expected move is the inputs the chain is pricing, not a forecast - realized moves above or below are normal under any distribution.
