It starts out noble. Once a company goes public, the first few town halls after the shareholder call the CEO or CFO will be like, "Don't worry about the stock price, we're better than all the other short-termist companies, we care about long term quality and blah blah." But bit by bit, little by little, like Pavlov's dogs the employees get trained to peek at that stock ticker around reporting time. And over time they sync up their decision making with that schedule, and internal planning starts to reflect it. And new initiatives get created and judged by investor reactions. And it's all downhill from there :-(
