Sharesight and Mezzi: From Performance Reports to Exposure Decisions

Updated September 26, 2026.

A performance report tells you about an outcome; an exposure review helps explain what you own; a financial decision adds your goals and constraints. Sharesight and Mezzi can contribute to different parts of that sequence. Both have tools relevant to underlying fund exposure.

This guide follows the sequence with illustrative numbers. It is not a customer case study, a product performance test, or a recommendation to change a particular investment. For current plans and the general product comparison, see Mezzi vs. Sharesight.

First, correct the false choice

Sharesight is not confined to backward-looking reports. Its Exposure Report can identify overlap between direct positions and supported ETFs, including consolidated portfolios. Mezzi offers Exposure X-Ray and a broader guidance experience using connected financial information and personal context. Sharesight Exposure Report; Mezzi account groups

The choice is therefore not “reporting or overlap.” Ask which part of your process needs help: reliable records, analytical views, interpretation in the context of your life, or implementation.

Moving through these stages is more useful than treating a single chart as an instruction to trade.

Stage 1: establish a record you trust

Suppose a portfolio begins a year at $200,000 and ends at $230,000 after a $20,000 contribution. The balance is up $30,000, but that is not a $30,000 investment gain. The timing of the contribution and any other cash flows affect the performance calculation.

Before comparing returns, reconcile the transactions and identify the measurement method. Do both views use the same start date? Does one include a closed position and the other omit it? Is a dividend recorded as cash, reinvestment, or neither?

Sharesight's reporting workflow is relevant here because it documents transaction and dividend tracking alongside performance reports. Sharesight features

The practical output is a record of what the report includes and what still needs correction. If historical transactions are missing, a precise-looking percentage can give a misleading sense of completeness.

Stage 2: choose an appropriate comparison

A benchmark is useful only if it relates to the portfolio's purpose. A household keeping a reserve for a known expense may intentionally hold a different mix from a stock index. A difference in returns does not, on its own, establish poor decisions.

Write down the objective before reviewing the result. Was the money intended for long-term growth, near-term spending, or a combination? Did a major contribution arrive late in the period? Did the household change its objective during the year?

This is where records and context meet. The report provides evidence; the objective determines what comparison is meaningful. If you cannot describe the objective, ask that question before responding to the performance number.

Do not use this exercise to promise future returns. A clear account of past results cannot remove uncertainty about what happens next.

Stage 3: look through the funds

Consider a simplified $100,000 portfolio containing $20,000 of Company A directly, $50,000 of Fund One, and $30,000 of Fund Two. Assume, solely for this example, that Company A is 8% of Fund One and 4% of Fund Two.

The direct position is 20% of the portfolio, but the simplified combined exposure is 25.2%. These are invented holdings and assumptions used to explain the arithmetic, not measured outputs from either application.

Sharesight's exposure product guide explains the same analytical distinction between direct and underlying ETF holdings. Mezzi's Exposure X-Ray provides a way to investigate supported fund exposures within its account experience.

In a real portfolio, check fund dates, unsupported holdings, and the total used as the denominator. Including a large property value in household net worth is not the same as including it in an investment-portfolio exposure calculation. Two percentages may differ because they answer different questions.

Stage 4: decide what the exposure means for you

A 25.2% exposure is a fact within the example's assumptions. It is not automatically a sell instruction. The next questions concern purpose and constraints.

Is the exposure intentional? Does employment income depend on the same company? Is part of the position subject to restrictions? Would a sale create a tax consequence? Could future contributions change the mix without a sale? Is a planned expense relevant to the timing?

Mezzi's AI Personalization can record the household context behind those questions. Banking, liabilities, and other assets can help represent the wider picture. A useful prompt might be:

Help me identify what we should verify before deciding whether this concentration fits our stated goal. Separate connected facts from assumptions and list the alternatives worth investigating.

This prompt asks for a reviewable process. It does not ask the system to replace missing records with certainty.

Stage 5: separate overlap from fees and taxes

Owning two funds with common holdings does not mean you pay two fund expense ratios on the same invested dollar. Each fund's expense ratio applies to the money invested in that fund. Overlap can still matter for concentration or unnecessary complexity, but the fee calculation must be accurate.

For illustration, a 0.75% expense ratio on $100,000 is $750 per year before changes in the invested value. A 0.03% ratio on the same amount is $30. The difference is $720. That arithmetic does not establish that the funds are interchangeable or that switching produces $720 of net benefit.

Investigate differences in holdings, objectives, trading costs, and tax consequences before considering a change. A lower stated fee alone does not settle the decision.

Similarly, an unrealized loss is not a complete tax strategy. Records, account ownership, purchases in other relevant accounts, and individual circumstances can matter. Neither a report nor a connected app should be treated as a guarantee that a transaction has no tax complication.

Stage 6: keep implementation accountable

Mezzi does not trade or move funds, and Sharesight is a tracking and reporting service rather than a broker. Sharesight service boundaries

If you choose an action, specify the person or institution responsible and keep the confirmation. If you choose no action, record why and what change would justify another review. A deliberate decision to wait is different from leaving the issue unresolved.

Where professional tax or legal work is required, involve the appropriate professional. Do not let the convenience of the analysis hide the need for implementation expertise.

When using both is worthwhile

Two tools can make sense when Sharesight holds the investment reporting record and Mezzi helps investigate broader household questions. That arrangement needs clear ownership of the data: source records remain available, manual entries are maintained, and differences are reconciled.

It is less useful when both tools become dashboards you rarely act on. Start with the missing task, then select the lowest-cost setup that covers it. Free or lower-tier access may be enough for an initial evaluation; the main comparison explains current US plan distinctions.

A successful review should leave you with a clearer decision or a precise missing-information request. It does not have to end in a transaction.

Frequently asked questions

Can Sharesight show overlap across ETFs?

Yes. Its documented Exposure Report combines direct and underlying holdings in supported ETFs and can operate on consolidated portfolios. Check coverage and report limits for the assets and plan you use.

Does overlap automatically make a portfolio bad?

No. It may be intentional. The useful question is whether the resulting combined exposure fits the purpose, risk considerations, and constraints you have identified.

Can I use Mezzi for tax-sensitive questions?

You can ask for guidance, but verify that the required records and context are available. Advice does not guarantee a tax result, and Mezzi does not execute transactions or file returns for you.

What should I do after the report?

Write down one decision the report raises, the facts it depends on, and the missing information. Explore Mezzi if you want to discuss that decision using connected accounts and saved personal context.
