Stockjobbers were institutions that acted as market makers in the London Stock Exchange. Prior to the "Big Bang" in 1986, every stock traded on the Exchange passed through a jobber's book, where they acted as intermediaries between stockbrokers. Immediately prior to the Big Bang, the leading jobbing firms were Akroyd & Smithers, Wedd Durlacher, Pinchin Denny, Smith Brothers, Bisgood Bishop and Charles Pulley.
