what are the functions of a jobber in the stock exchange?

Jobbers, now commonly referred to as market makers, act as intermediaries in the stock exchange by providing liquidity to the market. They buy and sell shares on their own account, facilitating transactions between buyers and sellers. By maintaining an inventory of stocks, jobbers help ensure that trades can be executed quickly and efficiently, reducing price volatility. Additionally, they earn profits through the spread between the buying and selling prices of stocks.
