What Are Financial Markets?
Financial markets are platforms where buyers and sellers trade assets such as stocks, bonds, currencies, derivatives, and commodities. They serve three essential functions: capital allocation (channeling savings to productive use), price discovery (determining fair value through supply and demand), and risk management (allowing participants to hedge or speculate).
- Primary Markets: Where new securities are issued. Companies raise capital through Initial Public Offerings (IPOs) or bond issuances. Underwriters (investment banks) facilitate the process, pricing the offering and distributing shares to institutional and retail investors.
- Secondary Markets: Where existing securities are traded between investors. The issuing company does not receive proceeds from secondary trades. Examples include the NYSE, NASDAQ, London Stock Exchange, and Tokyo Stock Exchange. Liquidity in secondary markets is what makes primary market investing attractive.
- Exchange-Traded vs OTC: Exchange-traded markets (NYSE, CME) have centralized order books, standardized contracts, and clearinghouse guarantees. Over-the-counter (OTC) markets trade directly between counterparties, with customized terms but higher counterparty risk.
Major Asset Classes
| Asset Class | Description | Key Markets | Typical Investors |
|---|---|---|---|
| Equities (Stocks) | Ownership shares in publicly traded companies. Shareholders have voting rights and claim on residual assets. | NYSE, NASDAQ, LSE, TSE, HKEX | All investor types |
| Fixed Income (Bonds) | Debt securities where the issuer pays periodic interest (coupon) and repays principal at maturity. | TRACE, Euroclear, Clearstream | Pension funds, insurers, central banks |
| Foreign Exchange (Forex) | Trading one currency for another. Largest market by volume ($7.5T/day). | EBS, Reuters Matching, FX swaps | Banks, corporations, hedge funds, central banks |
| Derivatives | Contracts whose value derives from an underlying asset. Includes futures, options, swaps, and forwards. | CME, ICE, Eurex, OTC markets | Hedgers, speculators, arbitrageurs |
| Commodities | Physical goods: energy (crude, gas), metals (gold, copper), agriculture (wheat, coffee), livestock. | CME (COMEX, NYMEX), LME, ICE | Producers, consumers, speculators |
Market Participants
- Retail Investors: Individual investors trading for personal accounts. Typically smaller order sizes, longer holding periods. Growing share of market through commission-free brokerages (Robinhood, Schwab, Interactive Brokers).
- Institutional Investors: Organizations managing large pools of capital. Pension funds (CalPERS, CPP), mutual funds (Vanguard, BlackRock), hedge funds (Bridgewater, Renaissance), endowments, sovereign wealth funds. Account for >80% of trading volume.
- Market Makers: Firms that quote bid and ask prices, providing liquidity by standing ready to buy or sell. They profit from the bid-ask spread. Examples: Citadel Securities, Virtu Financial, Jane Street.
- Investment Banks: Facilitate capital raising, M&A advisory, sales and trading, research. Major firms: Goldman Sachs, Morgan Stanley, JPMorgan, Citi.
- Regulators: Government bodies that oversee market integrity. SEC (US), FCA (UK), ESMA (EU), SFC (Hong Kong), JFSA (Japan). They enforce rules against insider trading, market manipulation, and fraud.
Key Market Concepts
Liquidity
The ability to buy or sell an asset quickly without significantly affecting its price. Highly liquid markets (US Treasuries, large-cap stocks, major currency pairs) have tight bid-ask spreads and deep order books. Illiquid markets (small-cap stocks, exotic derivatives, distressed debt) have wider spreads and price slippage on larger orders.
Volatility
A statistical measure of price dispersion over time. Typically measured as standard deviation of returns (historical volatility) or implied by option prices (VIX for S&P 500). High volatility creates both opportunity (larger price moves) and risk (greater uncertainty).
Market Efficiency
The Efficient Market Hypothesis (EMH) posits that asset prices reflect all available information. Three forms: weak (past prices), semi-strong (public information), strong (all information, including private). In practice, markets are semi-strong efficient most of the time, with anomalies that active managers attempt to exploit.
Bid-Ask Spread
The difference between the highest price a buyer will pay (bid) and the lowest price a seller will accept (ask). The spread represents the transaction cost of trading. Spreads narrow with higher liquidity and competition among market makers.
Major Stock Exchanges
| Exchange | Location | Market Cap (Listed) | Notable Listings | Type |
|---|---|---|---|---|
| NYSE | New York | ~$28T | Berkshire Hathaway, JPMorgan, Coca-Cola | Auction (specialist) |
| NASDAQ | New York | ~$25T | Apple, Microsoft, Amazon, Google, Meta | Electronic (dealer) |
| Japan Exchange Group | Tokyo | ~$6T | Toyota, Sony, Mitsubishi | Electronic |
| Shanghai SE | Shanghai | ~$7T | Kweichow Moutai, ICBC, PetroChina | Electronic (quota system) |
| Euronext | Amsterdam/Paris | ~$7T | LVMH, ASML, TotalEnergies, SAP | Electronic |
Trading Sessions and Settlement
Major equity markets operate on specific schedules. US markets: pre-market (4:00-9:30 ET), regular session (9:30-16:00), after-hours (16:00-20:00). Settlement follows the T+1 cycle (trade date plus one business day) for US equities as of 2024. Bonds and some derivatives settle on T+2 or T+3.
Orders can be market orders (execute immediately at best available price), limit orders (execute only at specified price or better), stop orders (trigger when price reaches a threshold), and Iceberg orders (display only portion of large order to minimize market impact).
