A firm sells a customer 100 shares out of its own inventory and adds a markup to the price rather than charging a separate commission. In this trade, the firm is acting as a:
- ABroker (agent)
- BInvestment adviser
- CTransfer agent
- DDealer (principal)correct
Why D is correct
When a firm trades from its own account and compensates itself through a markup (or markdown), it is acting as a dealer, or principal. A broker (agent) instead arranges a trade for a customer and charges a commission.
