In Level 5 you saw real estate: lots of capital, leverage, illiquid assets. The stock market is almost the opposite: you can start with very little money, buy and sell in seconds, and spread risk across hundreds of companies at once. Marta already touched on this in Level 2 with her index fund; this level goes into the detail of how it actually works.
A share isn't a token that goes up and down in price by magic, it's a real ownership stake in a company. As a shareholder, your money can grow in two ways: price appreciation (if the company becomes worth more over time) and dividends (a share of the company's profit paid directly to shareholders).
The rest of this level will be available very soon.
