A good stock broker is someone you can rely on to give you solid advice and protect your interests. Trust is key. And you get that by building an ongoing relationship with your broker. They should also be someone who remembers you exist. Especially when things are happening that you need to know about as soon as possible.
Clearly you don’t build a strong relationship with a broker — or anyone — in just a day or two. It takes time. And patience. And asking lots of questions. If they seem short with you or distracted or give vague answers, they’re not the right broker for you.
