The "explain like I'm 5" version, partly to answer you, and partly as a clarifying exercise for myself.
In a market, you trade dollars for other valuable things.
In a stock market, you trade dollars for stocks.
Why is a stock valuable?
It represents a small piece of a company. If you bought up all the pieces of a company, you would own the entire company. But most people can't buy an entire company, so they buy small pieces of a company instead.
Why would you want to trade dollars for a small piece of a company?
A few reasons:
1. Because a company owns valuable assets, and if you own part of a company, then you own a part of those valuable assets.
2. Because a company earns money, and if you own part of a company, then you get some of that money. (Either directly as a dividend, or indirectly as more your shares gain in value.) Think about it: if you own part of a company, then for some small fraction of the day, every single person in that company is working for YOU. YOU get the fruits of their labors for that fraction of the day. If you do this with enough companies, then you can quit your job.
3. Because a company makes decisions, and if you own part of the company, then you get to vote on how those decisions are made.
4. Because dollars become less valuable over time, by about 2% per year, assuming that the economy is operating as planned. (Inflation.)
