>Facebook has torched tens of billions of dollars of shareholder equity since it first went public. Not necessarily. Price movements in a stock are not necessarily caused by bad decisions of the company. Stock prices can change for many reasons outside of the company's control. By the article's logic, the Facebook torched a lot of shareholder value on the day of its IPO. But that day, Facebook made very few decisions, despite its price falling drastically. Rather than Facebook's bad decisions, I'd argue that investor uncertainty was the driver of the price movements.
