For most people, their 401(k) is their single largest retirement asset. It’s where a big chunk of savings grows year after year. But for all its importance, the 401(k) is often left sitting on an island.
Here’s what we mean. Investors may carefully build a diversified portfolio in their IRA or brokerage account, but their 401(k)—with its own mix of funds and strategies—rarely gets coordinated with the rest. The result? Inefficient overlap, unintended risk, and a portfolio that isn’t truly working as one.
Take a common example: a client has an IRA balanced 60/40 between stocks and bonds. But their 401(k), left on autopilot, is also loaded with target-date funds heavy in equities. Put together, the client isn’t 60/40 at all; they might be closer to 75/25 without realizing it. That hidden tilt can make a retirement plan riskier than intended.
Another issue is costs. Some 401(k)s offer a handful of high-expense funds as the default menu. Without oversight, investors may end up paying far more in fees than necessary. And because 401(k)s are typically viewed in isolation, those costs often go unnoticed.
The good news: your 401(k) doesn’t have to be a blind spot. At Hanover, we offer 401(k) aggregation—meaning your workplace retirement account can receive the same level of professional management as the rest of your portfolio. That allows us to coordinate every account into a single, deliberate investment strategy. No more overlaps, no hidden risk concentrations, and no drifting away from your long-term goals.
Retirement planning isn’t just about saving diligently—it’s about making sure all the moving parts work together. When your 401(k) is managed alongside the rest of your portfolio, you avoid hidden overlaps, manage risk more effectively, and keep costs under control. It’s a way to make sure every dollar you’ve saved is pulling in the same direction.
