No matter how many times you say it, that statement is not true. The problem is not now, nor has it ever been shareholder selling. The problem has always been a CEO who failed to follow through on the many things he said, therefor destroying share value, and losing investor confidence.
Investor selling was the result of loss in share value, not the cause of the drop. Shareholders can't be blamed for trying to salvage some portion of what they invested when the CEO continues to ignore calls for proof of value
