What defines the aggregation of client trade orders?

The aggregation of client trade orders refers specifically to the practice of combining orders of the same security for multiple clients into a single order. This process is typically undertaken for various reasons, including the potential for reduced transaction costs and improved execution prices due to the larger order size. When multiple client orders for the same security are aggregated into one larger order, it can enhance the likelihood of getting a better overall execution price compared to executing each client's order individually.

This practice helps investment advisers efficiently manage client trades and can lead to cost savings that may be passed on to clients. It is particularly beneficial in scenarios where liquidity might be a concern or where market conditions fluctuate substantially. By organizing trades in this manner, advisers can optimize trade execution and fulfill fiduciary responsibilities.

Other options do not correctly describe aggregation. Splitting orders of the same security for separate clients would inherently affect the benefits gained from executing a single large order. Combining orders of different securities does not fit the definition of aggregation since it pertains to orders for different securities rather than consolidating similar orders. Allocating trades based on client portfolio size involves distributing trade executions rather than aggregating orders for efficiency.
