The option contracts on IBB expiring on Jun 21st are the perfect way to play this situation and while the premiums have increased they have not increased enough across all strikes to reduce the expected returns below acceptable levels. However, given the murky picture for May 17th a little bit of patience may be a good idea prior to initiating a position.
