Jobber: A Dealer in Shares and Commodities

A detailed encyclopedia entry about jobbers, market-makers, and their roles in financial markets.

Introduction

A Jobber is a dealer in shares or commodities who holds a stock of the asset and trades as a principal. Jobbers are distinguished from brokers, who operate in the same markets but connect buyers and sellers rather than trading for themselves. The modern equivalent of a jobber is known as a market-maker.

Historical Context

Historically, jobbers played a crucial role in the London Stock Exchange before the “Big Bang” financial reforms of 1986. They provided liquidity by continuously quoting buy and sell prices, allowing investors to trade efficiently. Over time, the role evolved into what we now refer to as market-makers.

Types of Jobbers

  1. Stock Jobbers: Specialists in trading stocks and shares.
  2. Commodity Jobbers: Focus on trading commodities such as metals, oil, and agricultural products.
  3. Bond Jobbers: Deal primarily in bonds and other fixed-income securities.
  4. Currency Jobbers: Operate in the foreign exchange markets.

Key Events

  • Pre-1986: Jobbers operated exclusively on the trading floors of stock exchanges.
  • 1986 “Big Bang” Reforms: The London Stock Exchange underwent significant changes, abolishing jobbers and transitioning to an electronic trading system.
  • Post-1986: Emergence of electronic market-makers who continued the role of jobbers in the new trading environment.

Detailed Explanations

The Role of Jobbers

Jobbers, by acting as principals, took on the risk of holding a position in a security. They profited from the spread between the buy and sell prices, often providing immediate execution to traders.

Market-Makers: The Modern Jobbers

Market-makers, similar to jobbers, provide liquidity by standing ready to buy or sell at publicly quoted prices. They are essential in ensuring a smooth, efficient market.
