Imagine your company is worth 100€
You divide it into 100 shares of 1€ each.
If someone buys 10, they own 10%.
That's a stock.
In reality
Apple is worth trillions. Divided into millions of shares worth hundreds.
You buy 1 Apple share: you own a tiny real piece.
Why do they go up and down?
Up: People think it'll do well. Want to buy. Many buying = price up.
Down: Think it'll do poorly. Sell. Many selling = price down.
