This document discusses the key differences between brokers and advisors. Brokers are held to a "suitability standard" where they must provide options that suit a client's needs but may not be the least expensive or best match. Advisors are fiduciaries held to the "fiduciary standard" where they are required to put their client's interests ahead of their own. Brokers are typically commission-based while advisors' compensation is usually fee-based such as a percentage of assets under management. The document provides an example of how costs for mutual funds purchased through a broker can add up to 2-4% annually without an investor's awareness.
