stock market is like a shop where like the limbs of a company is sold. Now, the money you used to buy their limbs will be used by the company to fund other things for their own. U might wonder why some stocks are expensive. Well let's put it this way, let's say that Angelina Jollie announces that she's selling her parts. And we know that Angelina Jollie is very popular, so that's the reason why her parts are more expensive. We can also say that she have done some controversy so her value declines and people will be selling her parts to somebody else. People sometimes will take advantage of this because the value is now cheaper. But we know, Angelina Jollie is can regain people's trust and again will boost value. How do we know this? It's publicly displayed in the media. Media will be our market. We check the TV for news and see what's currently happening. From there, we can see the current status although in real world, their are tickers for this. Ticker names is like Apple is to APPL. Now let's say that Angelina Jollie's stock price was $50 when you bought her back in 2000 and today the price is $150 because you know, Angelina gains so much popularity she was all over the media. You decided to sell the stock and now you just made $100 out of your $50.
