Sell your stock and remove emotions. Focus on you and your family by setting up your finances for the long haul.
The writing has been on the wall for some months now. The day she she promoted Neri to be President, it was clear that the day is not far off for her departure. No one in their right minds, let alone wall street, should be surprised. They are lying if they claim analysts are concerned about her departure. They just want some lame excuses to swings the stock price around. Wall street lives for this kind of stuff. They make money regardless of if the stock price goes up or down. It is the poor individual investors who will be left holding the bucket.
