The stock market, explained way too simply
The one-sentence version
A share is a tiny slice of a company, and the stock market is just a very busy place for swapping slices.

The slightly longer version
A company, sliced up
A company that wants money to grow can cut itself into pieces and sell them. Each piece is a share. Buy one and you own a very small slice of the business: its buildings, its products, and a claim on its future profits.
The market is just the swapping
Once the slices are out there, people want to buy and sell them. A stock market is the place where that happens, the way a farmers’ market is where vegetables change hands. The company itself usually isn’t involved any more. It’s owners trading with would-be owners.
Why the price moves
A share is worth whatever someone will pay for it right now. If lots of people think the company will make more money in future, they’ll pay more for a slice, and the price goes up. If they start to doubt it, fewer want to buy, and the price drops. News, rumours and moods all push those guesses around, which is why prices wiggle every minute.
So is it gambling?
Over a day, it can feel like it. Over decades, the stock market has tended to grow because the companies in it have tended to grow, making more stuff and more profit. The slices you own grow with them. That’s the difference from a casino, where the house always wins in the end. It’s also why people say the market is for money you won’t need for a long while.
