Haha, the stock will tank on bad future prospects faster than you can sell. Being a short-termer in a stock only works if the other stockholders are in it for longer than you are, and believe in the long-term prospects.

Dividends are not a sign of short term investing. When the company's profits decline from short term thinking, the dividends disappear.

BTW, if you identify a company that is short-terming, and the other investors haven't caught on and tanked the stock, you can make a mint by shorting the stock. Got any success stories at that? Have you made money shorting McDonald's?
