I see what you mean. Loosing an intensic value is riskier than waiting for the option to expire. However if I have enough cash to exercise the options on the strike date and flip, all I would incur is a short term sales tax, right ? Obvioiusly this assumes the pps will be well north of my strike price on the expiration date. For CLSN, this should not be a problem.
I have 250 calls of 4's for Jan '14 and am trying to understand the best exit strategy..lol
