The stock will rise briefly, and modestly (maybe 3%) then it will crash to low 20s, losing about 30%. The gain will be due to layoffs, the fall will be a result of the intrinsic value and the general stock market.
The market, in general, is significantly overvalued. Why? Cheap money, primarily. Interest rates have been held down for 8 years making it a better choice to borrow money. The Fed has no more options (QE or negative rates) and a major correction is coming. Remember 2008? This will make 2008 look like a rose.
Cisco has borrowed and used the money to buy its own stock and compensate executives. The stock is at an al time high. Remember that 95% of cash is non-US and they can't bring it back without a 30% tax.
The once mighty Cisco is bleeding. SPs don't want the crap Switches with the crap foreign TAC support. Enterprises love AWS (Cisco has cloud? Who knew?)
Trying to retrain 70,000 people to sell software and code their own robot replacements has proven to be a monumental joke.
"So, I write a python script for ACI to do my teams job and then...oh sh--"
Cisco can't sell routers with their left hand and software routing with their right hand, yet that is what they are doing. The market has spoken. Facebook, IBM, Google, and even Apple (partner?) don't want or need Cisco.
Have you seen FBs NFV stuff?
Did you know AT&T, Cisco's largest customer is now selling virtualized networking that competes with Cisco.
This is just the beginning folks.
