Quote from jeffm:
Today, the SEP1340P is 100 points ITM and is trading for about 93. What can this put possibly trade up to? Anything over 100 is free arb money. I don't see any platinum between 93 and 100.
ATM, OTM and many ITM options would certainly have huge premium after a black swan. But we're talking WTF-ITM, not ATM.
What if IV were so high that the corresponding call was $15 bid? Wouldn't the arbs be willing to pay a time premium for the put?
