What a Financial Market Is

This lesson explains what people mean when they say "the market." It covers what is being traded, who is doing the trading, what an exchange is, and how an ordinary person reaches any of it.

None of this requires money to start understanding. Knowing the structure first makes the paperwork you meet later, like opening an account or reading a confirmation, much less confusing.

A financial market is where buyers and sellers trade assets

A financial market is any arrangement where buyers and sellers trade financial assets. An asset here means something you own that has value: a share of a company (a stock), a loan you have made to a government or a company (a bond), a currency, or a contract based on any of those.

The word "market" once meant a physical room where people shouted prices at each other. Today almost all trading happens through computer systems that match buy orders and sell orders. When you hear that a price "moved," it means buyers and sellers agreed on different prices than they did before.

There is no single financial market. There is a market for US government debt, a market for company shares, a market for currencies, and many others. Each has its own hours, its own rules and its own typical participants.

Individuals are a small part of the crowd

Individuals buy and sell in these markets, but so does nearly every other kind of organization. Companies raise money by selling shares or bonds, and they also invest cash they are not using. Governments borrow by selling bonds, including the US Treasury, which sells debt to fund federal spending.

Funds are pools of money from many investors, managed together. Pension funds, insurance companies, university endowments and mutual funds all trade in size. So do banks and specialized firms whose job is to stand ready to buy and sell, which helps other people find someone to trade with.

Being a small participant is not a disadvantage in itself. It does mean the price you see is set by the whole crowd, not negotiated by you.

An exchange is an organized venue with rules

An exchange is a regulated venue that brings orders together and publishes the resulting prices. It sets who may trade there, what the trading hours are, and what companies must do to have their shares listed. In the United States, exchanges are overseen by the Securities and Exchange Commission, the federal agency that regulates securities markets.

For stocks traded on US exchanges, regular trading hours run from 9:30 a.m. to 4:00 p.m. Eastern Time on weekdays that are not holidays. Some venues allow trading before and after those hours, though conditions there can be different and often worse for small orders.

Not everything trades on an exchange. Most bonds, for example, are traded directly between firms rather than on a central venue, which makes their prices harder to see.

The first sale of shares is not the same as later trading

When a company sells shares to investors for the first time, it is raising money for itself. That first sale is called an initial public offering, often shortened to IPO, and the money paid goes to the company (minus fees to the banks that organize it).

After that, those shares change hands between investors. The company is not part of those trades and receives nothing from them. Almost all the trading you will ever read about or take part in is this second kind: investors trading with other investors.

Here is the difference with round numbers. Suppose a company sells 1,000,000 new shares at $20 each. The company raises $20,000,000, which it can use to hire people or build things. A week later, an investor who bought 100 of those shares sells them to someone else at $22. That seller receives $2,200 and the company receives nothing. The price has changed, but no new money reached the business.

A brokerage account is how an individual reaches the market

You cannot place an order on an exchange directly. Individuals trade through a brokerage account, an account at a firm that is licensed to send orders to the market and to hold the assets you buy.

Say you deposit $1,000 and buy 20 shares at $50 each. Your order goes to your brokerage firm, which routes it to a venue where a seller is found. In the United States, most stock trades settle one business day after the trade date, so shares bought on a Monday are normally delivered on Tuesday. That standard, known as T+1, took effect on May 28, 2024.

Brokerage accounts carry real risks. The price of what you buy can fall, and you can lose money, including all of it. If the brokerage firm itself fails and is a member of the Securities Investor Protection Corporation, your cash and securities may be protected up to $500,000, including a $250,000 limit for cash. That protection covers the firm failing, not your investments losing value.

Which account and which assets suit you depends on your own situation, and a licensed professional can help with that decision.

What to remember

• A financial market is any arrangement, now mostly electronic, where buyers and sellers trade assets such as stocks, bonds and currencies.
• Participants include individuals, companies, governments and large pools of money such as pension and mutual funds.
• An exchange is a regulated venue with set hours and listing rules; US stock exchanges trade regular hours from 9:30 a.m. to 4:00 p.m. Eastern.
• A company receives money when it first sells shares; later trades happen between investors and send the company nothing.
• Individuals reach the market through a brokerage account, and the value of what they buy can fall.
