One thing that should be noted is that yesterday's decision to announce the new CEO on the same date that Cisco announced earnings was certainly not at all coincidental. It had everything to do with tactical compensation.
If Cisco had announced great earnings, the jnpr compensation committee would met and set the option price for Kheradpir at the price as of close of business the same day. As it is, that meeting will be deferred into the market digesting the Cisco miss so that his options strike price will be that much lower.
In other words, don't expect Juniper to step in to provide any stock price support by buying back for a bit until Kheradpir's option grant price has been locked.
