When acting as a principal, how do investment dealers generate revenue?

When an investment dealer acts as a principal, it trades with clients from its own inventory of securities. The dealer buys securities at a lower price (the bid price) and sells them at a higher price (the ask price). The difference between the bid and ask price is known as the "spread." This spread represents the dealer's gross profit or revenue on the transaction. This activity is also referred to as market-making.

A. Commissions are the primary source of revenue when a dealer acts as an agent or broker, facilitating a trade between two other parties.
B. "Tracers" is not a standard financial term for a source of revenue for investment dealers.
C. Brokerage charges are functionally the same as commissions and are associated with agency trades, not principal trades.

2. Investment Industry Regulatory Organization of Canada (IIROC). Glossary. The definition of "Principal" clarifies that a dealer acting in this capacity trades for its own account, and the profit is derived from the price difference, not a commission.
