Different Holdings Can Carry the Same Risk

Identify What Your Holdings Have in Common:

A portfolio can contain several holdings while relying heavily on the same companies, industries, or economic conditions. Counting positions gives you a starting inventory. Understanding their underlying exposures requires a closer look.

 

Consider a fictional portfolio containing a broad equity fund, a technology-focused fund, and shares in a large technology company. The company may also appear in both funds. Three separate purchases can therefore increase exposure to the same business, while other companies across the funds may share similar commercial risks.

 

Start by examining the underlying holdings using dated information. Record material overlaps, including repeated companies, sector concentrations, and geographic dependencies. Keep the size of each position visible because a small overlap and

a dominant concentration have different implications.

 

Then describe the common exposure in plain language. For example, “Several holdings depend substantially on spending by the same customer group.” That gives you something more specific to investigate than the number of funds in the account.

 

An overlap may be intentional. Record its purpose and assess whether the combined exposure fits your portfolio’s stated limits.

 

Choose one pair of holdings and identify their largest shared exposures.

Note the source date and any information gaps before drawing a conclusion about

how much diversification the pair provides.

Combine Repeated Exposures Across the Portfolio:

Once you identify an overlap, estimate its contribution across all relevant holdings. Looking at each position separately can conceal the total amount tied to the same company or risk source.

 

Suppose the fictional portfolio is allocated as follows:

  • Broad equity fund — 50% of the portfolio

  • Technology fund — 20% of the portfolio

  • Direct shares in Company A — 5% of the portfolio

  • Other holdings — 25% of the portfolio

 

Company A represents 4% of the broad equity fund and 10% of the technology fund.

Its contribution to the overall portfolio is therefore calculated as follows:

  • Through the broad equity fund — 50% × 4% = 2%

  • Through the technology fund — 20% × 10% = 2%

  • Through the direct holding — 5%

 

Total identifiable exposure to Company A — 2% + 2% + 5% = 9% of the portfolio.

 

This total assumes the other holdings contain no additional exposure to Company A.

If they do, include that exposure in the calculation.

 

These illustrative figures measure exposure to one company. They do not estimate how much the portfolio would lose under a particular event. That would require further assumptions about prices and the behaviour of other holdings.

 

Use compatible, dated information for the calculation. Record fund weights, portfolio weights, and any differences in reporting dates. Where information is incomplete,

label the result as a partial estimate.

 

Repeat the exercise for a material sector or another clearly defined exposure.

Keep categories consistent and check whether they overlap. Adding a company total to

a sector total that already contains it would count part of the exposure twice.

 

Record the combined estimate beside the purpose and limit you use to assess it.

Test How a Shared Exposure Could Affect Several Holdings:

A combined exposure estimate tells you where risk may be concentrated.

A stress scenario examines how several holdings could be affected by the same event.

 

Return to the fictional portfolio. Suppose Company A experiences a serious business setback. Both funds hold its shares, so the direct holding and the fund positions would all be affected through that ownership.

 

A broader event could reach further. If technology spending falls sharply, other companies in the funds might also face weaker demand. The exposure to that event could therefore extend beyond the 9% identified for Company A.

 

Choose one plausible adverse event and examine each holding against the same question. What connects this holding to the event?

 

Record the possible effects separately:

  • Direct effects — ownership of the affected company or asset

  • Related effects — dependence on similar customers, suppliers, financing, or demand

  • Access effects — possible difficulty selling or receiving proceeds when needed

  • Uncertainty — relationships or data you cannot establish reliably

 

Keep each connection supported by information about the holding. A shared sector label can prompt investigation, but it does not establish that every company would respond equally.

 

You can begin with a qualitative scenario. State the event, explain the relevant connections, and identify which holdings could be affected together. Any numerical loss estimate requires explicit assumptions and should remain labelled as a scenario result.

 

Use the exercise to identify concentrations that deserve closer assessment against

your portfolio limits.

Define What Each Concentration Limit Covers:

A concentration limit becomes usable when it specifies the exposure being measured, the holdings included, and the point at which a review is required.

 

For the fictional portfolio, a company limit would need to include direct shares and

the company’s contribution through both funds. A limit applied only to the direct holding would leave part of that exposure outside the check.

 

Write each limit with a clear scope:

  • Exposure — the company, sector, region, or other defined dependency

  • Measurement — how the combined exposure is calculated

  • Coverage — which accounts and holdings are included

  • Review trigger — the boundary or change that requires assessment

  • Response — the procedure to follow when the trigger occurs

 

Choose boundaries through your documented portfolio planning process,

taking account of objectives, access needs, and the consequences of concentration.

The illustrative percentages in this article describe one example and

provide no recommended limits.

 

Distinguish a measured breach from a data gap. If a fund’s underlying holdings are unavailable, record the uncertainty and the action needed to investigate it.

An incomplete estimate cannot establish that the exposure is within its limit.

 

Finally, specify when the measurement is refreshed. A new purchase, a change in fund composition, or movements in portfolio weights can alter the combined exposure.

Keep the calculation date and supporting sources with each review.

Recommended Framework:

Start with one material exposure. Combine its identifiable contribution across your holdings, examine a shared stress scenario, and check the result against a clearly defined portfolio limit. Keep missing information visible.

 

The Portfolio Risk Management System provides an educational framework for examining concentration, correlation, drawdowns, and liquidity within a portfolio.

 

The ten-document pack includes the main manual and nine supporting documents:

  • Portfolio Risk Management System

  • Portfolio Risk Map

  • Drawdown Response Protocol

  • Exposure Limit Framework

  • Correlation Risk Matrix

  • Volatility Control System

  • Liquidity Protection Protocol

  • Risk Escalation Thresholds

  • Capital Preservation Declaration

  • Portfolio Risk Review Sheet

 

Use the documents to organise your assessment, record your assumptions, and

define review procedures for the risks you identify.

Wealth compounds quietly.

Systems don’t create results overnight.

They create conditions where consistency can compound over time.

This site exists to document that process, honestly.
