AI Prompt to Check Portfolio Diversification and Asset Overlap

What you need

You need a complete itemized list of all your assets and their current values ready to paste. Write down cash reserves, individual corporate equities, broad market exchange-traded funds, bonds, property holdings, and alternative assets.

For mutual funds and index trackers, specify the geographic focus and asset type rather than relying solely on the fund provider name. For instance, note whether an exchange-traded fund tracks developed markets, emerging economies, or specific industrial sectors like semiconductors. Identify the primary operating currencies of your foreign holdings so the model can evaluate currency diversification separately from asset class distribution. If you hold physical real estate or company pension entitlements, include their estimated values so your full economic net worth appears in the assessment.

Use the snapshot block below to compile your data. Enter your balances, copy the entire block, and paste it into your AI session alongside the prompt text below.

Here is my financial snapshot. Use only these numbers.

Currency: [e.g. EUR]

[name] — [category] — [value]
...

LIABILITIES

...

CONTEXT (optional but improves the answer)
Monthly income after tax: [amount]
Monthly spending: [amount]
Amount I add to savings or investments each month: [amount]
Value of the same assets 12 months ago: [amount]

The prompt

Copy this exact text and paste it into ChatGPT, Claude or Gemini directly beneath your snapshot block.

You are a financial analyst. Using my snapshot above, judge how diversified I am.

1. Assess diversification across asset classes, geography, currency and time horizon.
   Handle each separately.
2. Where I appear diversified on the surface but am not underneath, explain the
   overlap.
3. Describe what genuine diversification would add in my case, in concrete terms.
4. Name the point at which adding more holdings stops helping and explain why.
5. End with one question I should answer about my own situation before changing
   anything.

No specific funds or tickers. Ask for missing detail rather than assuming it.

What good output looks like

The output should begin with four separate evaluations covering asset classes, geographic dispersion, currency denomination, and time horizon. It assesses whether your wealth spans uncorrelated return drivers, such as equities, sovereign bonds, and cash, or remains tethered to a single asset class.

In the second section, the model must expose phantom diversification where your portfolio appears broad on the surface but concentrates risks underneath. For example, if you hold an S&P 500 fund, a global tech ETF, and an American growth fund, the model reveals that all three funds concentrate top allocations inside the same ten mega-cap technology corporations. It calculates the effective overlapping weight across those combined holdings.

The third section explains what authentic diversification would introduce to your specific balance sheet. It describes how adding an uncorrelated asset class, such as inflation-indexed government bonds or global real estate, dampens overall portfolio volatility during equity bear markets without eliminating long-term compounding.

The model then defines the boundary of over-diversification, explaining the principle of diminishing returns in portfolio construction. It notes that owning more than twenty to thirty individual stocks or four broad index funds adds administrative complexity and fund fees without meaningfully lowering idiosyncratic risk.

The response concludes with a pointed self-examination question about your investment horizon or liquidity needs before you adjust existing allocations.

What this can't tell you

This prompt cannot read through the underlying daily portfolio constituent filings of exchange-traded funds. It relies on the general asset descriptions and fund names you provide in your snapshot.

The model cannot calculate exact historical correlation coefficients or beta metrics between your specific combination of funds. It does not know whether your tax jurisdiction penalizes foreign dividend distributions or imposes exit taxes on offshore mutual funds. It has no insight into your job stability or whether your domestic living expenses face local inflation that foreign assets fail to track. It cannot verify whether private asset valuations match real-world secondary market liquidity. Check fund prospectuses directly to confirm overlap. The output provides educational framework analysis rather than tailored investment advice.

Doing this without the retyping

Auditing fund overlap with external chatbots means retyping your asset lists, checking ticker categories, and copying values whenever you buy new holdings. In Sumio, this diversification check is one of sixty-two prompts built directly into the app. It evaluates your asset spread with one tap against the holdings you already record, keeping diversification metrics current.
