Quote from spindr0:
That will lock in a loss if the time premium received for the short call does not exceed the premium paid for the put (OP's post implies that assignment would be a break even).
Absolutely true if the put is available for a penny or two but that may not necessarily be the case because the call has a Holland Tunnel wide spread and you can hide a lot of put premium in there (if expiry is a further month and/or higher IV).Quote from ogarbitrage:
The opposite put of a 100 delta call would have to be cheap. Assuming in my writing that he could pick it up for a penny, 2 at most.
