How Often Should You Rebalance Your 401(k)? A Clear Answer for Young Investors

Here's a scenario that plays out a lot: you started your first real job, sat through the HR onboarding session, picked some funds that sounded reasonable, and moved on. That was two — maybe three — years ago. You've checked the balance a few times. Things look... fine? Probably fine. You're not sure.

The thing you almost certainly haven't done is rebalance. And if you're being honest, you're not entirely sure what that means or how often you're supposed to do it.

This article answers that question directly. No jargon, no vague "it depends" non-answers. By the end you'll know what rebalancing is, how often to actually do it, and how to tell if your 401(k) needs attention right now.
