>>136618057I don't know much but I've learned some stuff during the last couple of weeks.
Basically, if a company is public (not private like Valve, let's say), you can buy "parts" of it (these are called shares/stock). If a lot of people are buying, it's price go up (the big black number you can see in Google finance), or if a new game is released/etc. On the other side, if the company announces loses or firing of the staff, the company's value decreases. If people sell more than buy, then it also decreases.
Now, how do people gain money? Basically, they buy when the price is low and sell when the price is high. Let's say I buy a couple hundred shares from EA right now when the price is low. If, let's say, EA's price goes up in a month and the company's price is, let's say, 16$, my profit it pretty because I bought when the price was low (14) and for every share I gained an additional 2$.
