All week, the options for FFIV have showed that FFIV was more likely than not, heading to $97.50 as that was the strike price (on the PUTS side) that had the highest in volume for all the calls and puts! Thus, if one knows how to interpret options each week AND IF the big guys who play the options are RIGHT, then just by looking at the options each week for FFIV can give you a great idea of what to expect for where FFIV will go in the week by week's end - and since Monday (when FFIV hit a high of $106.98), that price for this week for the WEEKLY options, showed FFIV going "more than likely" to $97.50 (around there) to end the week! and voila - where did it go?? it ended just below $97.50 thereby ensuring the puts at that strike price ended at almost worthless.
Next week, it's not yet clear of where FFIV will end next week for the monthly options expiration for October - Monday will bring more clarity but as of right now, it looks like it's EITHER going to be $95 OR $100 to end the week! check options info for this! Also, there's really strong support at $95 - so, next week, FFIV might have a low of $95 and end the week at around $100!
