Why would a company care about the price of its own shares in the stock market?
Because it's a good indicator of how much their asset worth. In oversimplified example, wouldn't you care how much your house, car, laptop worth? Over the course of your life you might need to buy a bigger house, sell your car etc. to cope with your financial goal / situation. It's similar in company's case but with much more complexity.
