Summary

Written by a model from the transcript; not yet reviewed.

Brian Preston and Bo Hanson break down seven of the most common mistakes made by do-it-yourself investors and explain how to identify and fix them. Drawing on decades of advisory experience, the hosts cover pitfalls ranging from overlapping fund holdings and poor asset location to ignoring risk tolerances, overlooking beneficiary updates, and losing track of old retirement accounts. They also address the dangers of trying to time the market versus maintaining a consistent purchasing strategy.

Throughout the episode, the hosts emphasize the importance of understanding underlying investment holdings, aligning tax strategies with the correct account types, and avoiding emotional panic during market downturns. They provide concrete data, such as a study showing two-thirds of workers manage finances without a professional and statistics on millions of lost 401k accounts, while offering actionable self-audit tools for long-term wealth building.
