The short version
- Stock markets trade ownership in companies on regulated exchanges during fixed hours.
- Currency markets are a dealer network that runs 24 hours on weekdays; most retail access is leveraged.
- Crypto trades every hour of every day on many venues, with far thinner investor protection.
Financial markets explained in one sentence: they are places, physical or electronic, where buyers and sellers agree a price for something. What that "something" is changes everything else. Owning a slice of a company, swapping one currency for another and holding a digital token look similar on a price chart, yet they differ in who stands behind them, when you can trade and what protects you if something goes wrong.
What is actually changing hands
A share is a legal claim on part of a company: a proportion of its future profits and, usually, a vote at its annual meeting. Its value ultimately rests on what that business earns. A currency pair such as EUR/USD is a price for exchanging one national currency into another; nobody expects the euro to "earn" anything, so its value moves with interest rates, trade and confidence. A cryptocurrency such as Bitcoin is a token recorded on a public ledger; it produces no profit and no interest by itself, so its price depends almost entirely on what the next buyer will pay.
That difference in what sits underneath shapes how investors think about each market. Share investors can study sales, costs and cash flow. Currency traders study central banks. Crypto holders mostly study adoption, supply rules and sentiment.

Where and when trading happens
| Stock market | Forex | Crypto | |
|---|---|---|---|
| Venue | Regulated exchanges such as the NYSE, Nasdaq or London Stock Exchange | Over the counter: banks, dealers and brokers quoting each other | Many independent trading platforms and on-chain protocols |
| Hours | Fixed weekday sessions, e.g. 09:30 to 16:00 New York time | Sunday 17:00 to Friday 17:00 New York time | Continuous, including weekends |
| Settlement | US shares settle one business day after the trade (T+1) | Spot trades settle in two days in the wholesale market; retail CFDs never settle into currency | On the blockchain, typically within minutes |
| Typical retail access | Buying the shares outright through a broker | Leveraged contracts (CFDs or spread bets) with a dealer | Buying coins on a platform or holding them in your own wallet |
Because stock exchanges close overnight and at weekends, prices can jump between one session's close and the next open when news breaks in between. Our market hours board shows which exchanges are in session right now.
How prices are set
On a stock exchange, orders meet in a central order book: buyers post the most they will pay, sellers the least they will accept, and a trade happens where the two meet. The gap between the best buy and sell price is the spread. Busy large-company shares tend to have narrow spreads; small, rarely traded companies can have wide ones.
Currency prices are quoted by dealers, so a retail trader is usually trading against the broker's own price feed rather than an exchange book. Crypto prices form separately on every platform, which is why the same coin can show slightly different prices in different places at the same moment.

Rules and protection
Listed companies must publish audited accounts and disclose material news promptly, and brokers that hold shares for clients in major markets must be authorised and keep client assets separate from their own. Many countries also run compensation schemes if an authorised firm fails, up to a limit.
Retail leverage on currency and index contracts is capped in the UK and EU (30:1 on major currency pairs, 5:1 on individual shares), and clients there have negative balance protection. Crypto rules vary much more by country; in the UK, for example, crypto-derivatives cannot be sold to retail consumers at all. In practice, a coin held on an unregulated platform may have no compensation scheme behind it.
Risk: a comparison beginners often get wrong
It is tempting to rank markets from "safe" to "risky". A better approach is to look at the three things that cause most losses: volatility (how far prices swing), leverage (how much borrowed exposure you take) and counterparty risk (whether the firm holding your assets could fail or disappear). A diversified share fund bought without borrowing scores low on two of those. A leveraged currency position scores high on leverage. A small coin held on an offshore platform can score high on all three.
How the three markets connect
These markets are separate but not isolated. A change in US interest rates moves the dollar in the currency market, affects how investors value company profits in the stock market and often shifts appetite for speculative assets such as crypto, all on the same afternoon. A British investor holding US shares owns a currency position without meaning to: if the dollar weakens against the pound, the holding is worth less in pounds even if the share price has not moved. Learning a little about each market helps you understand why your own portfolio moves the way it does.
Which market should a beginner learn first?
For most people building long-term savings, the stock market, usually through broad index funds, is the natural starting point, because shares are tied to real business profits and can be bought without borrowing. Currencies and crypto are worth understanding, if only because they affect the value of overseas holdings and appear constantly in the news. Continue with:
Reader questions
Is the stock market open 24 hours?
No. Each exchange has fixed weekday sessions and closes at weekends and on its public holidays. Some brokers offer limited trading before and after the main session, but liquidity is thinner then.
Why do currency prices move so little compared with shares?
Major currencies are backed by large economies and heavily traded, so daily moves are usually a fraction of a percent. That is why forex is typically traded with leverage, which magnifies both gains and losses.
Does crypto have the same investor protection as shares?
Usually not. Share custody and broker conduct are tightly regulated in major markets, while crypto protection depends on the country and platform and is often much weaker.
