Lesson
Best execution refers to the duty of an investment adviser or broker to ensure that client orders are executed at the most favorable terms available, considering factors such as price, speed, and likelihood of execution.
Historical Example
In the past, there have been instances where brokers have been fined for not providing best execution to their clients. One such case involved a broker who consistently routed client orders to a specific market even though better prices were available elsewhere. This resulted in clients receiving inferior execution prices, and the broker was ultimately fined and sanctioned by regulators.
Real-World Example
Imagine you are an investment adviser and receive an order from a client to buy 100 shares of a particular stock. You can route the order to one of two markets: Market A, which is offering the stock at $50 per share, or Market B, which is offering the stock at $49.95 per share. In this case, best execution would require you to route the order to Market B, as it provides a better price for your client.
