By the end of this lesson you understand what a stock exchange is, what role it plays as a regulated institution, and how a stock's price is determined within it.
\nA stock exchange is an organized, regulated financial market specifically dedicated to trading shares of companies listed on it. "Organized" means it follows clear rules about how trades are executed; "regulated" means a supervisory body oversees that those rules are followed and that participants receive truthful information -- in Spain, that body is the Comisión Nacional del Mercado de Valores (CNMV).
\nA very common misconception is thinking that the exchange "sets" a stock's price, as if it were a catalog with prices decided in advance. That's not how it works: the price continuously emerges from the meeting of buy orders and sell orders from all participants. If at a given moment more investors want to buy a stock at the current price than investors are willing to sell it, the price tends to rise; if the opposite happens, it tends to fall. The exchange simply organizes that meeting in an orderly and transparent way -- it doesn't decide the outcome.
\nIt's important to distinguish two different moments in a stock's life on the exchange:
\nThe vast majority of the trades you see reflected in a stock's price, day to day, happen in the secondary market, between investors -- not between an investor and the company.
\nThe Madrid Stock Exchange, the New York Stock Exchange (NYSE), and the Nasdaq are real examples of stock exchanges. Each organizes trading for the shares of the companies listed on it, with its own hours, admission rules, and trading systems -- but on all three, the underlying mechanism is the same: matching buy and sell orders to form a price.
\nA stock exchange is an organized, regulated market where shares of listed companies are bought and sold. Each stock's price emerges from the meeting of supply and demand, not from a decision by the exchange or the company. Most trades happen in the secondary market, between investors -- not directly with the company.
\nWho really sets a stock's price on an exchange?
\nWhat's the difference between the primary market and the secondary market?

It doesn't exchange products or services like a supermarket does: it exchanges **financial assets** -- stocks, bonds, currencies, among others.\n\nA company that needs capital can issue shares (selling ownership stakes in the company) or bonds (borrowing money with a promise to repay it, with interest, on a future date). Whoever has savings can buy those shares or bonds, expecting a return in exchange for the risk they take on.\n\nFinancial markets serve three functions, even if it isn't obvious at first glance:\n\n- **Channeling savings toward productive investment**: without a market to connect them, the savings of some and the financing needs of others wouldn't easily find each other.\n- **Providing liquidity**: the ability to convert an investment back into available cash by selling it to another market participant.\n- **Setting prices**: an asset's price emerges from the meeting of those who want to buy it and those who want to sell it -- supply and demand -- not from a unilateral decision.\n\nThere are different types of financial markets depending on what is exchanged in them: the equity market (stocks), the fixed-income market (bonds), the currency market, and the commodities market, among others. This Academy focuses mainly on the equity market, but you'll gradually see the rest as well.\n\n## Example\n\nApple is a company listed on the Nasdaq, a U.S. stock exchange. Anyone with a brokerage account can buy one share of Apple and become, for that small part, a part-owner of the company -- that exchange (money for an ownership stake) happens precisely in a financial market, not in a store or a traditional bank.\n\n## Common mistakes\n\n- Confusing \"financial market\" with \"stock exchange\" -- the stock exchange is one specific type of financial market, the one for stocks, not the only one that exists.\n- Thinking that money is made automatically or with a guarantee in a financial market -- in reality there's real risk of loss; it's an exchange between parties, not a game with a guaranteed outcome.\n\n## Summary\n\nA financial market connects those who have savings with those who need financing, through the exchange of financial assets -- not physical goods. It serves three functions: channeling savings toward investment, providing liquidity, and setting prices through supply and demand. The stock exchange is one of the best-known financial markets, but not the only one.\n\n## Self-check\n\nWhat is exchanged in a financial market, instead of goods or services?\n\nWhy do we say that a financial market gives \"liquidity\" to whoever invests in it?","bodyHtml":"By the end of this lesson you can distinguish what a financial market is, identify what is exchanged in it, and tell it apart from other markets you already know, like a consumer goods market.
