Just report back the call/put parity has recently been restored. okay, there are still some difference beween ATM IV of call and out, but been within a reasonable range in my mind. If we look back, does it sound like a 'free lunch' offered by the pre-mature market? During the time of C/P parity coming back, the underlined seems to be quite stable. I still don't quite get why such thing happened in a quiet time.
Thank all of you for your nice feedback to the original question!
