There are a lot of discussion about the similarities and differences between investment and gambling. What do you think is the main difference between investing and gambling? To bring in some context, the stock price of Hertz, the car rental company went up from less than one dollar to as high as about $6 after the company with a few days. Usually when a company files for bankruptcy protection, the equity value will be wiped out because the company's assets are barely enough to pay for the creditors. Do you think investors buying and selling Hertz stocks after the company filed for bankruptcy are investing or more like gambling?
