What a Financial Market Is

Why this matters

"The market" gets mentioned constantly, usually as if everyone knows what it is. Knowing what actually happens when you buy an investment, and who is on the other side, makes the rest of this module much easier to follow. It also clears up one of the most common misunderstandings about stocks.

What a market is

A market is simply a place where buyers and sellers meet and agree on a price. A financial market is one where the things being traded are financial assets. Today, most of that "place" is electronic: computers matching orders rather than people shouting on a trading floor.

There are markets for almost every kind of financial asset:

• Stock markets, where shares of companies are traded.¹
• Bond markets, where loans to governments and companies are traded.
• Money markets, for very short-term borrowing and lending.
• Currency markets, where one country's money is exchanged for another's.
• Commodity and derivatives markets, for things like oil and wheat, and for contracts based on other assets.

This module focuses on the stock market, because it's where most individual investors start. The same basic ideas apply to the others.

Two markets: primary and secondary

A share of stock usually changes hands many times over its life. It helps to separate the very first sale from everything after it.

• The primary market is where new securities are sold for the first time, and the company that created them receives the money.² A company's first sale of shares to the general public is called an IPO, or initial public offering.³
• The secondary market is where those existing securities are then bought and sold between investors.⁴ This is what most people mean by "the stock market."

Event	Who pays	Who receives the money
STU Corp's IPO: 10 million new shares at $20	New investors	STU Corp, about $200 million before fees
A year later, Maria buys 50 shares at $25	Maria, $1,250	Dev, the investor who sold them
Two years later, the price is $40	No one	No one. STU Corp's cash is unchanged

STU Corp is fictional and the numbers are hypothetical. The point is the pattern: the company raised money once, in the primary market. After that, a rising or falling share price changes what investors own, not what the company has in the bank.

Why the secondary market matters

If companies only get money in the primary market, why does the secondary market matter so much? Two reasons.

It lets investors get out. Few people would buy shares in an IPO if they could never sell them. Knowing there's a busy market where shares can be sold later makes investors willing to buy in the first place. That ease of selling is called liquidity, and it's one of the main things markets provide.

It sets prices. Every trade is an agreement between a buyer and a seller about what a share is worth right now. Millions of those agreements, based on everything buyers and sellers know and believe, produce a market price. That process is called price discovery. Companies watch their share price closely because it affects how easily they can raise money in the future, and what their shares are worth when used to pay employees or buy other companies.

Key takeaways

• A financial market is any place, now mostly electronic, where buyers and sellers trade financial assets.
• In the primary market, the company sells new securities and receives the money. An IPO is a company's first public sale of shares.
• In the secondary market, investors trade existing securities with each other. The company isn't paid.
• Secondary markets provide liquidity and set prices, which is what makes primary markets work.

Check your understanding

You buy 20 shares of a large, well-known company through your brokerage app. Where does your money most likely go?

1. To the company, to help it grow.
2. To another investor who sold you the shares.
3. To the stock exchange, which owns the shares.

Why would fewer investors buy shares in IPOs if there were no secondary market?

1. They'd have no easy way to sell their shares later.
2. IPO shares would be more expensive, because fewer brokers could offer them.
3. Companies would stop paying dividends to IPO buyers.
