What is the Difference Between a Jobber and a Broker in Stock Trading?

In the world of stock trading, the terms jobber and broker refer to two different types of intermediaries who facilitate the buying and selling of securities. Though they both operate in the stock market, their roles, functions, and the way they interact with clients and the market itself differ significantly. Understanding these differences is crucial for anyone engaged in trading or investing.

1. Definition and Core Functions

Jobber (Market Maker)

A jobber, also known as a market maker in many modern markets, is an individual or firm that buys and sells securities on their own account to provide liquidity in the market. They are not directly involved with the public or individual clients. Instead, they operate within the market to ensure that there are always buyers and sellers available, thereby facilitating smooth trading.

• Main Role: Provide liquidity by continually offering to buy or sell securities.

• Nature of Business: Trading on their own account.

• Interaction with Clients: No direct interaction with public clients. They trade only with brokers or other market participants.

• Profit Model: Jobbers earn profits through the bid-ask spread, the difference between the price they are willing to buy a stock (bid) and the price they are willing to sell it (ask).

Broker

A broker, on the other hand, is an intermediary between the jobbers (or the market) and the public. Brokers do not trade on their own accounts but instead execute trades on behalf of clients. They earn commissions for facilitating these transactions.

• Main Role: Execute buy and sell orders for clients.

• Nature of Business: Facilitating trades for clients.

• Interaction with Clients: Direct interaction with public clients or institutional investors.

• Profit Model: Brokers earn money primarily through commissions or fees for the services they provide to their clients.

2. Key Differences in Trading Operations

3. Risk Exposure

Jobber’s Risk

Jobbers, since they trade on their own accounts, take on significant market risk. If the market moves unfavorably against their position, they may incur losses. Their job is to manage this risk by making sure they buy low and sell high within short time frames. They depend heavily on market movements and timing to make profits.

Broker’s Risk

Brokers, in contrast, face far less direct market risk because they are simply executing trades on behalf of clients. They do not hold positions in the market themselves (except in specific scenarios like proprietary trading divisions in large firms). However, they have reputational risk — if they fail to execute trades efficiently or provide poor advice, their client base may erode.

4. Client Interaction

Jobber

Jobbers do not interact with individual clients. Their trades are done through brokers or directly within the exchange, typically on a wholesale basis. Their purpose is solely to maintain market liquidity, and they rely on brokers to bring clients’ orders to them.

Broker

Brokers are client-facing and focus on understanding the client’s needs, investment objectives, and risk tolerance. They provide advice and services such as trade execution, portfolio management, and financial planning. Their role involves building relationships and trust with clients, whether they are individual retail investors or large institutional clients.

5. Market Impact

Jobbers’ Impact on the Market

Jobbers are essential for the smooth functioning of the stock market because they provide the liquidity that allows trades to happen efficiently. By consistently offering to buy and sell securities, they narrow the bid-ask spread and ensure that investors can execute trades without causing dramatic price swings.

Brokers’ Impact on the Market

Brokers impact the market by bringing buy and sell orders to jobbers or the open market. They help clients make investment decisions and ensure that trades are executed quickly and at the best possible price. Broker can also influence market trends through their research and recommendations.

6. Jobbers in the Modern Stock Market

Historically, jobbers were prevalent in older stock exchanges, like the London Stock Exchange, where they were key players in making markets. However, with the advent of electronic trading, the role of jobbers has evolved into that of market makers, firms, or individuals who play a similar role by providing liquidity on modern trading platforms.

In today’s markets, major financial institutions, like banks or specialist trading firms, act as market makers, ensuring that there's enough liquidity in securities trading. These modern-day jobbers operate using sophisticated algorithms to manage their trades.

7. Brokers in the Modern Stock Market

In the digital era, brokers have become more accessible to the general public through online trading platforms. These platforms offer clients the ability to place trades directly via the Internet, often at lower commission rates. Brokers now range from full-service brokers, who provide personalized investment advice and portfolio management, to discount brokers, who focus solely on trade execution.

8. Technological Evolution: From Open Outcry to Electronic Markets

Both jobbers and brokers have adapted to significant technological shifts. The transition from open-outcry trading floors to fully electronic exchanges has transformed how both roles function.

• Jobbers have transitioned from physical market makers to algorithm-driven market participants.

• Brokers now utilize online trading platforms and high-frequency trading systems to execute client orders rapidly and with precision.

9. Choosing Between a Broker and a Jobber

As an individual investor, your main point of contact will always be a broker rather than a jobber. Jobbers or market makers function behind the scenes to ensure the smooth flow of transactions, while brokers provide the personalized service and trading execution you need to buy and sell securities.

However, if you're trading in more complex or institutional environments, understanding the difference between these two market participants becomes more critical. Large investors might interact directly with market makers (jobbers) when executing big trades.
