What it means
A fund's name or description may suggest broad diversification, but the top holdings show how much is really riding on a handful of names. If the ten biggest positions make up half of the fund, its results will depend heavily on those companies.
If they make up only a small share, the fund is spread widely. Each holding is shown as a percentage of the fund's total value, called its weight.
Funds usually publish the list monthly or quarterly, and the data may be a few weeks old. The list tells you which companies, bonds or other assets the manager considers most important.
Investors use the list to check for overlap. Someone who owns several funds may find that each one holds the same large companies, which means the combined portfolio is less diversified than it appears.
Looking at the top holdings across all funds shows the true exposure to each company. Top holdings also reveal style and risk.
A fund with large positions in a single sector such as technology will rise and fall with that sector. A fund whose top holdings are mostly large, stable companies will behave differently from one whose top holdings are smaller, faster-growing businesses.
Be careful about what the list leaves out. It shows only the largest positions, not the many smaller ones, and it is a snapshot that can be out of date by the time you read it.
Funds can also change their holdings quickly, so the list should not be used as the only reason to buy or sell. For index funds, the top holdings mirror the index, so the largest companies in the index take the largest weights.
This means that an index fund can be more concentrated than people expect, if a few giant companies dominate the index. Checking the top ten before investing is a simple way to avoid surprises.
In practice
Real-world examples.
Example
An investor reads the fact sheet for a global equity fund and sees that its top ten holdings make up 47% of the fund. The investor realises the fund is more concentrated than its name suggests and compares it with a broader alternative.
Example
A financial adviser reviews a client's three funds and finds that the same technology company is among the top holdings in all three. The adviser reduces one of the funds to cut the overlap and moves the money into a fund with very different holdings.
Example
A pension trustee asks the investment manager for a list of the top holdings each quarter. The trustee uses the list to check that the manager is following the stated strategy and not drifting into unrelated areas.
Formula
Calculation
Concentration of the top holdings = sum of the weights of the top holdings
Dollar exposure = amount invested x concentration
Suppose a fund's ten largest positions have weights of 8%, 7%, 6%, 5%, 5%, 4%, 4%, 3%, 3% and 2%.
Concentration = 8 + 7 + 6 + 5 + 5 + 4 + 4 + 3 + 3 + 2 = 47%.
An investor who puts $200,000 into the fund has 200,000 x 47% = $94,000 invested in those ten companies.
The largest single position, at 8%, equals 200,000 x 8% = $16,000, so a 25% fall in that one share would cost the investor 16,000 x 25% = $4,000.Case study
Seen in the real world.
Oakfield Family Office is an illustrative, fictional company managing money for a wealthy family. It held four equity funds, each described as diversified, with a total of $8 million invested.
The investment analyst combined the top ten holdings from all four funds and found that one large technology company appeared in each of them. In total, that single company represented about 9% of the family's equity portfolio, or $720,000.
The illustrative response was to replace one of the funds with a more distinct strategy and to set a limit of 5% on any single company across the whole portfolio. The analyst concluded that looking only at fund names had hidden a risk that the top holdings list made plain. The family now asks each manager for a fresh list every quarter, and the analyst adds them together in one spreadsheet to track the overall exposure to each company.
Watch out
Common mistakes.
- Assuming a diversified fund has no concentration risk, when the top holdings may account for a large share of the fund.
- Treating the list as current, when it may be weeks or months old.
- Looking at each fund in isolation and missing the overlap across several funds.
Questions
People also ask.
What are top holdings?
They are the largest investments in a fund or portfolio, usually the ten biggest, shown with their percentage weights.
Where do I find a fund's top holdings?
They are shown on the fund's fact sheet, its website and in reports published by the fund manager, and many fund platforms also display them on the fund's summary page.
Why do they matter?
They show how concentrated the fund is, what drives its returns and how much it overlaps with your other investments.
