This value resetting (what I call the elimination of overvaluation) is not value destruction because the overvaluation would disappear anyway. The resulting stock price decline will generate substantial pain for shareholders, board members, managers and employees. The prospect of this value resetting pain makes it difficult for managers and boards to
