Why prices move
News, demand, and what people believe.
A stock's price isn't set by the company — it's set by buyers and sellers, just like trading cards. When good news makes lots of people want to buy, the price goes up. When scary news makes people want to sell, it goes down. So prices move on what people believe will happen next. 📈
Words to know
4Demand
How many people want to buy something — more demand usually pushes the price up.
Earnings day
The day a company reports how much money it made — prices often jump or drop after.
Guidance
A company's own guess about how it will do next — investors care a lot about it.
Priced in
When news everyone already expected is built into the price, so the stock barely moves when it's announced.
