## **Introduction**

Financial markets are organized in a variety of ways to facilitate the trading of securities. Understanding the core market types, order mechanisms, and market microstructure is critical for evaluating price formation, liquidity, transaction costs, and risk management as tested in CFA Level 1. This article reviews the organization of markets, order types, the role of intermediaries, and the fundamentals of market microstructure that underpin exam questions across investment asset classes.

## Types of Financial Markets and Trading Venues

Markets can be classified by the nature of their organization, trading process, and the types of securities traded.

### Primary vs. Secondary Markets

> **Key Term: Primary Market**
> The market where new securities are issued and sold to initial investors, providing capital to issuers.
>
> **Key Term: Secondary Market**
> The market where existing securities are bought and sold among investors, enabling liquidity and price discovery.

### Trading Venues

Three core trading venue types are tested on CFA Level 1:

- **Exchanges:** Centralized marketplaces where buyers and sellers transact according to formal rules; most require listing and compliance.

- **Over-the-Counter (OTC) Markets:** Decentralized networks where dealers quote prices for securities unlisted on exchanges.

- **Alternative Trading Systems (ATS)/Electronic Communication Networks (ECN):** Electronic platforms that match buy and sell orders, often anonymously, outside traditional exchanges.

## Market Structures: Order-Driven, Quote-Driven, and Brokered

Financial markets can be structured in several ways:

> **Key Term: Order-Driven Market**
> A market in which buyers and sellers submit orders that are publicly displayed and matched according to set rules, with prices determined by supply and demand (e.g., most stock exchanges).
>
> **Key Term: Quote-Driven Market (Dealer Market)**
> A market where dealers continuously quote prices at which they will buy (bid) or sell (ask) securities, providing liquidity and standing ready to trade as principal (e.g., NASDAQ, most bond markets).
>
> **Key Term: Brokered Market**
> A market where brokers arrange trades between buyers and sellers, typically used for assets with low trading frequency or that are less standardized.

## Types of Orders

Order classification is essential for the CFA exam. Common order types include:

- **Market Order:** Execute immediately at the best available price.
- **Limit Order:** Specify a maximum purchase price (buy) or minimum sale price (sell); not guaranteed to execute.
- **Stop Order:** Becomes a market order when a set price (stop price) is reached.
- **Stop-Limit Order:** Becomes a limit order at the stop price.

> **Key Term: Market Order**
> An instruction to buy or sell a security immediately at the best available price in the market.
>
> **Key Term: Limit Order**
> An instruction to buy or sell a security at a specified price or better; execution is not guaranteed.
>
> **Key Term: Stop Order**
> An order that becomes active for execution only when the security's market price reaches a designated level, triggering a buy or sell.

### **Worked Example 1.1**

A CFA candidate is told: “XYZ stock is trading at \$50. An investor enters a limit buy order at \$48 and a stop sell order at \$45.” Explain what will occur as the market price moves.

> **Answer:**
> The limit buy order at \$48 will only execute if the price falls to \$48 or below; it will not execute immediately. The stop sell order at \$45 will not activate unless the price falls to \$45, at which point it becomes a market sell order and is likely executed at the prevailing price, which may be lower than \$45.

## Order Execution and Trading Process

The trading process includes several steps:

1. **Order submission:** Investor gives instructions to a broker or a dealer.
2. **Order routing:** Order may be routed to venues based on price, liquidity, or other factors.
3. **Order matching:** In order-driven markets, orders are matched based on price–time priority. In quote-driven markets, dealers take the other side.
4. **Order execution and confirmation:** After matching, the trade is executed and confirmed to both parties.

## Market Intermediaries

> **Key Term: Broker**
> An agent who executes trades on behalf of clients for a commission, without taking any proprietary position.
>
> **Key Term: Dealer**
> A market participant who trades for its own account, standing ready to buy or sell at quoted prices and profiting from the bid-ask spread.
>
> **Key Term: Exchange**
> A formal marketplace where financial instruments are listed and traded under specified rules.

Brokers provide access, route orders, and seek best execution for clients, charging a commission. Dealers provide liquidity by quoting bid and ask prices.

## Market Microstructure Fundamentals

Market microstructure examines how trading processes, rules, and market participants influence price discovery, liquidity, trading costs, and informational efficiency.

> **Key Term: Market Microstructure**
> The study of the processes and outcomes of exchanging assets under explicit trading rules, including how prices are formed, liquidity is provided, and trading costs arise.

### Key Microstructure Concepts

- **Liquidity:** The ability to buy or sell quickly in desired quantities with minimal price impact and cost.
- **Bid–ask spread:** The difference between the dealer’s quoted purchase and sale prices; a measure of transaction cost and liquidity.
- **Market depth:** The volume of orders available above and below the current price; deeper markets absorb larger trades with less price impact.
- **Transparency:** The degree to which order flow and prices are visible to market participants.
- **Price discovery:** The process by which market prices reflect information in order flow and trading.

> **Key Term: Bid–ask Spread**
> The difference between the highest price a buyer is willing to pay (bid) and the lowest price a seller is willing to accept (ask); a direct cost to traders and a proxy for liquidity.
>
> **Key Term: Liquidity**
> The degree to which an asset can be quickly bought or sold in the market at a price close to its quoted value.
>
> **Key Term: Market Depth**
> The volume of buy and sell orders at different prices; a market with high depth can accommodate large orders with little price change.

### **Worked Example 1.2**

A dealer quotes a bid of 100.2 and an ask of 100.5 for a government bond. An investor sells 1,000 bonds at market; the trade executes at 100.2. The investor’s trading cost is 0.3 per bond (the spread), for a total cost of \$300.

> **Answer:**
> Selling at the bid incurs the bid-ask spread as the cost. The dealer profits from buying at 100.2 and, potentially, selling to another investor at 100.5.

## Trading Costs and Price Impact

Trading costs include:

- **Explicit costs:** Commissions, fees, and taxes.
- **Implicit costs:** Bid–ask spread, market impact from large orders, and opportunity cost.

Slippage refers to the difference between the expected price and the actual execution price due to market movements or lack of liquidity.

## Market Quality and Factors Affecting Liquidity

Market quality and liquidity are influenced by:

- Number and activity of market participants
- Rules on short selling, order transparency, and tick size
- Trading volume and frequency
- Presence of multiple venues and access to information
- Risk and reward for liquidity provision (bid-ask spread)

Markets with high liquidity, low spreads, high depth, and transparency are considered high quality. Fragmented markets may reduce transparency and increase implicit costs.

### **Exam Warning**

> When answering microstructure questions, ensure you distinguish clearly between order-driven and quote-driven systems. Many candidates confuse the roles of brokers and dealers in quote-driven markets on the exam.

## **Summary**

Understanding market organization, order types, and microstructure is fundamental for correct responses on CFA Level 1 questions. Distinguish venue types, match order instructions to trading objectives, and identify liquidity sources. Recognize how execution venues and microstructure affect pricing, costs, and risk.
