option delta

Thanks, Doobs.

 

Are you referred to the option's bid being below parity, as in worth less (two words)?

 

An option ATM (at the money, i.e. the option strike price is equal or about equal to the price of the underlying) has a delta of about 50 (0.50). Only when its deep ITM (in the money) does the delta reach 100 (1.00).
