Investment dealers are people or firms who buy and sell securities for their own account, whether through a broker or otherwise. They play an important role in the Canadian and global financial markets because they are market makers, create liquidity, and help promote long-term growth in the market. They also provide investment services to investors, such as underwriting securities, raising capital, and offering advice. By assisting with the exchange of capital for a financial instrument, they facilitate the flow of funds between savers and borrowers, and between different sectors and countries. The other options are not accurate descriptions of the role of investment dealers. References: Dealers: Definition in Trading, Meaning and Comparison to Brokers, Investment Dealers Definition
