Answer:
Shares are essentially a stake in ownership of a firm offering stock as a method of raising capital. Owning stock can sometimes allow you to receive dividends, a certain share of net profit from an accounting period, but most people make short term monetary gains by trading stocks at a higher value than when they bought it. I would not recommend investing in stocks without a financial consultant to explain things in more detail and someone who can create a portfolio that fits you specifically instead of trying to jump on hot stocks that anyone can do but many tend to fail at.
