How to read the BSAC implied-range data

The implied range is 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.

BSAC 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 BSAC 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. The expected move is the inputs the chain is pricing, not a forecast - realized moves above or below are normal under any distribution.
