Securities brokers, like Hilary Zimmerman, have a legal obligation to always act in the best interests of their customers. Part of this means conducting the necessary due diligence to handle their customer’s accounts to this best of their ability. When brokers let this responsibility go awry, their customers can suffer financially for it. Negligence turns out to be one of the most common things that securities brokers are accused of.
