You you think the Alibaba stock price will go up after the IPO, then it might be worthwhile to hold them at least until Friday and see what the market thinks of BABA...... your options don't expire for 30+ days, which gives you some time to decide what to do after Friday.
I have been accumulating the October $50's and I can sleep at night...... just know there are going to be some swings, so make a game plan up now and try like mad to stick with it.
