Is Your ShareBuilder 401k Portfolio Underperforming?

ShareBuilder 401k runs workplace retirement accounts, where defaults and a set fund list can hold an allocation away from a broad index baseline.

Pure Benchmarks ranks real ShareBuilder 401k portfolios against thousands of other verified investor portfolios across nine standardized risk categories, from 100% equity to 90% fixed income. Every portfolio is recategorized daily from actual end-of-day holdings, and Community Nests shows exactly where your ShareBuilder 401k portfolio ranks against other real ShareBuilder 401k clients in the same risk category — built entirely from verified portfolio data, with no firm that manages money able to see any data point on the platform.

Why your ShareBuilder 401k portfolio can lag a pure index baseline

The default-menu ceiling. Workplace plans limit choices to a set menu and often default balances into a single target-date fund. Convenient defaults and a bounded fund list can quietly hold the allocation away from a broad low-cost index baseline.

What to review on a ShareBuilder 401k portfolio

  • Confirm which funds in the plan menu carry the lowest expense ratios versus the defaults.
  • Compare the workplace allocation with a simple diversified index over time.
