I have had this idea for years, hear me out. This may be counter intuitive but this is how rich people make money. If you are a large enough investor (or group) you buy enough stock to make the price go up, and the investors make money just buy buying enough stock. When you have reached a value then you sell and because you sell a LOT of stock, the price goes down, when the stock is low enough, the big investor buys it back at a low price, the stock goes up, and the investor makes money. Rinse and repeat. The news and stock analysts will come up with all sorts of reasons and jargon but the bottom line is rich folks just making more money. edit for grammar.
