Quote from jwcapital:
Not true. Here is an example--Last year, January 2008, the ES plunged 60 points on MLK's birthday. That Friday, I placed 4 covered puts ATM. After the 60 point plunge, my underlying showed a profit of $12,000.00 and my puts showed a loss of $7,000.00 for a net gain of $5,000.00. Yes, the gain was less than the total premiums received, but there was no way I was waiting until expiration to try to make the extra gains. As things turned out, if I waited, I would have turned a nice gain into a loss. So, with due respect, the math held.
These are OH SO WRONG on so many levels!Quote from nitro:
That is not quite correct. Skew is a factor anytime you are buying or selling synthetics vs the vanilla. In fact, to a professional options trader, they can be vastly different.
It boggles my mind that that there are people here that need to be convinced that put-call parity actually works, skew or no skew.
So I propose this. jwcapital and nitro, what say you that we put some money on the table? Let's do some trades, you and I, and we'll establish who's right experimentally.
