The furthest BAC has moved away from the mean is 19% Over the last year or so. BAC has moved around 17% to the upside the past few months with no significant pull back. BAC is set for "breath" in price action. If negative news develops it could amplify the downward move. I like the Dec 27th 30-30.5 puts here as a conservative wager. You could look lower if you want to stretch out to next year (JAN). They are cheap and with a 3-4 week expiration could see some nice returns.
