Mezzi Fund Proxies: Fill Gaps in 401(k) and 529 Analysis

The October 31, 2026 release adds fund proxies to Mezzi’s analysis.

Some funds in your 401(k) or 529 appear in Mezzi with a balance but limited information about their holdings or price performance. A fund proxy helps fill that analytical gap.

A proxy is a similar publicly traded fund used as a stand-in for analysis. Assigning one changes the data Mezzi uses to estimate exposure. It does not replace the fund in your account, move money, or place a trade.

See the overlap that missing fund data can hide

A stock you own directly may also sit inside your retirement and education-savings funds. If Mezzi cannot look through those funds, part of your exposure can be missing from the picture.

Once you confirm a suitable proxy, Mezzi can use its stock/bond mix and underlying holdings to estimate your fund’s exposures in Exposure X-Ray. That gives the conversation more context about allocation, sector concentration, and overlap across accounts.

Proxy-based views are estimates. The stand-in may differ from your actual fund in holdings, allocation, fees, strategy, and performance. Review those differences before accepting a match.

Start with your fund’s documents

Download the fund prospectus or other fund information from your plan provider and upload it to Mezzi. A name alone may not identify the exact strategy or share class.

Ask Mezzi to identify funds with missing data, propose a similar public fund where a reasonable match exists, explain the differences, and ask you which assignments to apply. If information is insufficient, the next step is to obtain it—not guess a proxy.

The October announcement included these illustrative candidates:
