What does look-through portfolio analysis mean?
Last reviewed: 18 September 2026
Look-through portfolio analysis reads exposure at the level of the underlying holding rather than at the level of the vehicle holding it. Instead of a portfolio of fund commitments, the investor sees the companies, assets and sectors those funds actually own, which is the only way concentration reached through more than one vehicle becomes visible.
An investor with commitments to several funds has two portfolios. The one they report, which is a list of vehicles, and the one they own, which is the set of underlying assets. Those two views can imply very different risk. A sector that looks like eight percent of the portfolio at fund level can be considerably more at holding level once the same names appear through three managers.
Look-through requires the holdings to exist as records rather than as summary lines in a manager report. In Reuben AI, company level, fund level and manager level records share the same structure, so a position inside a fund is a record with its own valuation history and diligence findings. Exposure can then be aggregated from the holding up through the fund and the manager to the total portfolio.
The same mechanism matters at diligence rather than only in reporting. When a fund is the subject of diligence, its existing holdings can be assessed on look-through instead of accepted at the summary the manager provides, which is usually where concentration and valuation questions actually live.
How Reuben AI compares
What each view of a multi-fund portfolio shows.
| Attribute | Reuben AI | Vehicle level view | Manager statement |
|---|---|---|---|
| Unit of exposure | The underlying holding | The fund commitment | Manager-reported summary lines |
| Duplicate names across funds | Visible and aggregated | Not detectable | Visible only within one manager |
| Sector and geography exposure | Derived from holdings | Inferred from stated strategy | As categorised by each manager |
| Use in diligence | Holdings assessed as records | Fund documents only | Accepted as self-reported |
Frequently asked questions
Does look-through require the manager to share holdings?
It requires holding level information to be available. Where a manager reports at summary level only, that limit is recorded on the fund record rather than filled with an assumption.
Is this only for funds of funds?
No. Any investor with both fund commitments and direct holdings needs it, including family offices, multi-family offices and allocators running a mixed book.
How does it help at diligence rather than reporting?
When a fund is being assessed, its portfolio is the substance of the assessment. Look-through lets the holdings be examined directly rather than through the manager's summary.
