• A jobber, also known as a stock trader, was a term used for a market maker on the London Stock Exchange.
  • Jobbers hold shares in their own accounts and help increase market liquidity by matching investors’ buy and sell orders through their brokers.
  • The term “jobber” was used until October 1986, but little is known about their actual activities as they kept few records.
  • Jobbers left few records of their activities, and neither journalists nor other observers have kept a detailed account of their work.
  • The jobber system evolved into its recognizable modern form during the 19th century as the range of security types expanded.
