When and how should I simplify a messy, overlapping portfolio?

If you've accumulated a dozen funds, old 401(k)s, and overlapping holdings you can't explain, it's time to simplify. Start by listing every account and fund with its dollar value and expense ratio, then look for redundancy — multiple funds tracking the same index, or high-cost funds duplicating cheap ones. The cleanup: consolidate old 401(k)s into an IRA via rollover, sell redundant funds inside tax-advantaged accounts (no tax cost there), and rebuild toward a simple two- or three-fund target. In taxable accounts, go slower to manage capital gains — sell losers freely, and trim winners gradually or redirect new money instead. The endpoint is a portfolio you can understand at a glance and rebalance in minutes. Simplicity isn't just tidier; it reduces fees, mistakes, and the temptation to tinker. A messy portfolio often quietly costs you in overlapping fees and unclear risk.
