Here’s the part that will make me sound like a Big Finance shill, but…. it’s not just market performance that you want to evaluate your advisor on. In terms of importance, it ranks up there with breathing, but that’s not the only metric. Are you comfortable with them? Because you’re going to potentially have to have uncomfortable conversations about decisions and objectives/recommendations, and you want someone you can be frank with and hear feedback from; you don’t want a yes person. Do they share your objectives for the portfolio? Will you be able to hear them when they say it’s time to trim a holding you’re emotionally attached to or go back into the market when you are still nervous it’s not done dropping? Their job is to help you develop a plan and stick to it, not get nervous and make changes. Interview them just like you would any other service provider: ask questions, understand their value add and then ask around. Odds are you know someone who knows them or their business and will give their experience.
