Well that would be typical of options. I get a report each month one week 'before' the put and call positions expire on the major stock index ETFs. And the report shows what the major indexes must close at one week later at option expiration to cause the most financial pain to both the put 'AND' call owners. And guess what...... it's right on the money every month closing on the 3rd Friday at that exact point that would cause the majority of put and call owners to lose the most. More than a coincidence it seems...........
