What is a fiduciary? Everyone hears this word. A fiduciary is a person that has a registration, they are registered as a fiduciary, and that person has an obligation to choose Investments that are the best for the client and not themselves. For example, if there’s an investment that has a couple of different options, and one of them pays the better commission to the financial advisor, but isn’t the better fit for the client, that financial advisor has an obligation where they must choose the right investment for the client.
