- Explain why a market price can change and why quants care
A financial market brings together people who want to buy and people who want to sell. They trade and agree on a price. You use markets all the time, such as when you buy groceries. A financial market follows the same basic idea, but people trade financial assets instead of food.
An asset is something you can own that has value. A financial asset gives you a claim on something else. A stock, for example, gives you a claim on part of a company's future profits. A bond gives you the right to be repaid on a loan. For now, picture buyers and sellers meeting and settling on a price.
Intro Financial Markets
Savers have money to invest, while other people and organizations need to raise it. The introduction shows how financial markets connect them.
What gets traded
There is a different market for each type of asset. You will study all of them later. At this point, you only need to recognize the names and know what each asset represents.
Key terms
- Stock (also called a share or equity)
- A small piece of ownership in a company. If you own one share, you own a tiny part of that business.
- Bond
- A loan you make to a company or government. The borrower pays you interest and promises to return your money later.
- Currency
- National money, such as the US dollar or the euro. Currencies are traded against each other in the foreign exchange market.
- Commodity
- A basic physical good such as oil, gold, wheat, or natural gas. Traders buy and sell commodities in standard units.
- Security
- A tradable financial asset, usually a stock or bond.
A market can be a physical place, like an exchange floor full of traders. Today, almost all trading happens through computers that match buyers and sellers in a fraction of a second. The setting has changed, but buyers and sellers still need to find each other.
| Market | What is bought and sold | Everyday example |
|---|---|---|
| Stock market | Shares of ownership in companies | Buying one share of Apple |
| Bond market | Loans to companies and governments | Lending to the US government by buying a Treasury bond |
| Foreign exchange (forex) | One currency for another | Swapping US dollars for euros before a trip |
| Commodity market | Physical goods in standard units | A bakery locking in the price of wheat months ahead |
Three jobs markets do
Markets can look like places where traders bet on prices. They also do useful work for the economy. Three jobs come up again and again in finance: finding prices, making trade easier, and moving savings to companies and governments that can use the money.
- Price discovery. Buyers and sellers trade until they settle on a price. That price is the market's current estimate of what the asset is worth, and it can update within seconds when news arrives.
- Liquidity. A liquid market lets you exchange an asset for cash without waiting long or pushing the price far against yourself. You can buy when you want in and sell when you want out.
- Capital allocation. Markets move savings toward companies and governments that can use the money. More money tends to reach the projects investors consider valuable.
Match the job to what it does
Pair each market job with its description.
A price is an opinion
A price is different from a measurement such as the temperature. It marks the point where buyers and sellers currently agree to trade. If enough of them change their minds, the price moves. Thoughtful investors pay attention to how that agreement forms instead of treating the latest price as a fixed fact.
A market price combines many opinions about what an asset is worth into one number.
Markets, Efficiency, and Price Signals (Crash Course Economics)
Prices carry information about what people want and what things cost. Watch how those signals guide decisions across the economy.
Why quants care
A quant uses data and math to make investment decisions rather than relying only on instinct. A quant strategy usually looks for a small, measurable error in the current price and expects that error to disappear later. To search for that kind of opportunity, you first need to understand what a price means and how buyers and sellers create it.
Why did the price move?
A company reports much higher profits than investors expected, and its stock price jumps within minutes. Which market job are you watching in action?
Price discovery happens when new information changes what buyers and sellers are willing to pay.Put it in your own words
In two or three sentences, explain to a friend what a financial market is and why prices move. Use your own words.

Model answer
A financial market is a place or system where people buy and sell assets such as stocks and bonds. Buyers and sellers agree on a price, and that price changes when new information changes what they think the asset is worth.
The rest of this unit covers the main asset types, the way an exchange matches a trade, and the numbers shown in a stock quote. Those pieces will help you understand where a stock's price comes from.
