What Does This Mean?

The relationship between investors and securities brokers exists on a foundation of trust. The reason that investors can generally feel secure in trusting their broker is because they are aware that brokers are obligated to always act in their customers’ best financial interests. This obligation is also known as the broker’s fiduciary duty. Brokers who breach this duty work toward the erosion of that trust, which in turn can significantly damage the broker/investor relationship.
