The major dealers on the stock market are brokers.
Brokers are individuals or firms that act as intermediaries between buyers and sellers on the stock market. They facilitate the buying and selling of stocks by matching buyers with sellers, and they earn a commission on each transaction they facilitate.
Brokers play an important role in the stock market because they provide liquidity, which is the ability to buy or sell stocks quickly and easily. They also provide valuable advice and information to investors, helping them to make informed decisions about which stocks to buy or sell.
Jobbers, on the other hand, are a type of dealer who buy and sell stocks for their own account, rather than on behalf of clients. They are less common on modern stock markets, and their role has largely been replaced by electronic trading platforms.
Overall, brokers are the major dealers on the stock market, providing liquidity, advice, and information to investors, and earning commissions for facilitating transactions.
