Tragedy of the stock market: infinity can hit a company even if both management and shareholders are fully committed to modest long term stability (apparently this is absolutely not what happened at nvidia).

A company can get into the sights of "infinity believers" even if they try not to. Infinityists will honestly believe that the stock is a very good buy and whenever a "stability lover" has to sell, they will outbid the next stabilityist. Price goes up, it becomes more visible to infinityists and so on. Eventually infinityist will outnumber stabilityist and management will enter "or die trying" mode on promises they never made. Or be replaced.
