Was talking to a former CBOE floor trader this am. He suggested in lieu of all the restrictions, fees, lack of availabity when trying to establish a short stock position was to sell deep ITM calls for parity. Basically, understood him right up to the "parity" part. I understand parity, but can someone explain "parity" in context to this position. He obviously is trying to sell at more advantageous pricing. Just not getting the swing in regard to the trade here. Thanks.
