Stock Market Basics (How the Stock Market Works!)

You've seen an auction — people shouting prices, the highest bid wins. Well, here's a secret: the entire stock market works exactly like that. Every second of every day.

One giant, never-ending auction

On one side, you have buyers — people who want a stock, each shouting the price they'll pay. On the other side, sellers — people who own the stock, each shouting the price they'll accept. When a buyer's price and a seller's price match — boom. A trade happens. That's it. That is the entire stock market: one giant, never-ending auction.

Bid and ask, simply

The buyer's price is called the bid. The seller's price is called the ask. When they're close enough, they meet in the middle and the trade goes through. Millions of these little deals happen every second — and the last price anyone paid becomes the stock's current price. That's the number you see flashing on the screen.

Where do stocks come from?

Imagine you run a lemonade stand and you want to open ten more stands, but you don't have the money. A bank loan means debt. So instead, you do something clever: you split your business into a million little pieces and sell them to the public for the very first time. That first sale has a fancy name: an IPO — an Initial Public Offering. The company collects a pile of money to grow with — and the buyers get their little pieces.

After the IPO, it's people trading with people

Here's the part most people miss. After that first sale, the company is done — it already got its money. From then on, it's just people trading pieces with each other. When you buy a stock today, your money goes to the person selling it — not the company. The company only got paid once, on day one.

Pressing buy

So what happens when you press buy? Your order zips into the marketplace, finds a seller asking your price, and — done — the stock is yours. The whole thing takes less than a second. You never meet the seller. You never see the company. You just own a little piece of it now.

So now you know the basics. The market is an auction. Buyers bid, sellers ask, and trades happen where they meet. Companies raise money once, at the start, through an IPO. And after that, it's people trading with people — all day, every day.
