A mutual fund can carry a “low risk” label even when its top 10 holdings form a large part of its portfolio. At first, this may appear difficult to understand. If a fund places a large share of its money in a small number of companies, it is natural to ask whether that makes the fund less safe.
The answer is not always yes.
Portfolio concentration is one form of risk, but it is not the only form of risk. A fund with fewer major holdings may still have a relatively lower overall risk profile if those holdings are large, established companies, have sound financial positions, and come from different sectors.
At the same time, a fund with many holdings is not automatically low risk. A portfolio can hold 50 or more stocks and still face substantial risk if most of those companies are small, highly volatile, or exposed to the same economic factor.
For this reason, a “low risk” label should not be read as a promise that the fund will have only small losses. It is better viewed as one part of the overall risk assessment.
Concentration Risk Is Only One Part of Risk
When a mutual fund has a large share of its portfolio in its top 10 holdings, the fund has a higher degree of concentration than a portfolio with a more equal spread across many companies.
For example, consider a fund with the following profile:
| Portfolio feature | Example |
|---|---|
| Top 10 holdings | 55% |
| Largest holding | 8% |
| Other holdings | 45% spread across 40+ stocks |
| Company profile | Mostly large, established companies |
| Sector exposure | Spread across several sectors |
A top-10 share of 55% means that more than half of the portfolio sits in the fund’s 10 largest positions. That is a material level of concentration when compared with a broad market portfolio.
However, that figure alone does not establish that the fund has a high overall risk level.
The nature of those 10 companies matters. If the companies are large and established, their price behaviour may differ from that of smaller and less established companies. A portfolio with exposure across several sectors may also have a different risk profile from a portfolio where most of the major holdings belong to one sector.
Therefore, the 55% figure should be treated as a fact about portfolio structure rather than as a final conclusion about the fund’s safety.
A More Concentrated Example
A different portfolio could have this structure:
| Portfolio feature | Example |
|---|---|
| Top 10 holdings | 75% |
| Top 3 holdings | 35% |
| Other holdings | 25% |
| Sector exposure | Several holdings from the same sector |
| Company profile | Some smaller or highly cyclical companies |
This structure creates a different set of concerns.
Here, 75% of the portfolio is concentrated in only 10 companies. More importantly, the top three alone account for 35%. This means that a relatively small number of positions can have a substantial effect on the fund’s result.
The sector issue adds another layer. If several major holdings depend on the same economic factor, they may face pressure at the same time. A fund may therefore appear diversified by stock count but still have meaningful exposure to one common source of risk.
This is why the number of stocks by itself does not provide a complete picture.
Why Ten Holdings Can Still Be Reasonable
A portfolio with 10 major holdings is not necessarily poorly diversified.
Imagine that the largest positions include companies from financial services, technology, consumer goods, healthcare, energy, and other unrelated areas. A problem in one industry may not affect every major position in the same way.
The size and financial condition of the companies also matter. Large, established businesses may have different financial characteristics from smaller companies with less predictable earnings.
This does not mean that large companies cannot fall sharply. They can. A large company can face a serious fall in its share price because of weak earnings, debt concerns, regulatory action, economic changes, or other factors.
The point is narrower: the concentration percentage alone cannot tell an investor how much risk the fund carries.
Why Fifty Holdings Do Not Guarantee Low Risk
The opposite situation is also important.
Suppose a fund owns 50 stocks. At first sight, this may appear well diversified. Yet the portfolio could still have substantial risk if many of those companies belong to the same sector or have similar business characteristics.
For example, several companies may depend on the same commodity price, interest-rate cycle, consumer demand, export market, or regulatory environment.
In such a case, a fall in one common factor may affect many holdings at once.
This creates what can be described as common or correlated risk. The stocks are different names, but their economic exposure may be similar.
Therefore, diversification should not be judged only by the number of securities in the portfolio.
What the “Low Risk” Label Means
In the Indian mutual fund context, the Risk-o-meter is intended to show the level of risk associated with a mutual fund scheme. It should not be treated as a guarantee against loss.
A fund with a lower risk label can still lose value. The label does not mean that the investor’s capital is protected from market movements.
This distinction is important because the words “low risk” can sometimes sound stronger than they really are.
A safer interpretation is that the fund has been placed within a particular risk category under the applicable framework. That category reflects the fund’s assessed risk profile. It does not remove market risk and does not promise a particular return or a maximum loss.
The relevant regulatory framework also recognises risks related to concentration and exposure to securities and sectors. Such rules help place limits and controls around portfolio construction, but they do not make an investment free from loss.
Concentration and Actual Portfolio Behaviour
An investor may also examine how a fund behaved during difficult market periods.
Past performance cannot establish what will happen in the future. However, historical data can help show how the portfolio reacted when markets faced stress.
For example, an investor can examine periods when:
The broader market fell sharply.
A particular sector faced pressure.
Interest rates changed.
Commodity prices moved substantially.
Small-cap or mid-cap shares faced a major correction.
The purpose is not to assume that the same result will occur again. Instead, the purpose is to understand the fund’s historical behaviour and the possible effect of its portfolio structure.
A fund with a concentrated portfolio may show a larger effect from movements in its major holdings. A more diversified fund may spread that effect across a larger number of securities. But actual results depend on the securities and their relationships with one another.
The Top 10 Percentage Is Useful but Incomplete
The top-10 percentage is a useful starting point.
Consider the following comparison:
| Measure | Portfolio A | Portfolio B |
|---|---|---|
| Top 10 holdings | 55% | 75% |
| Top 3 holdings | Not specified | 35% |
| Largest holding | 8% | Not specified |
| Remaining portfolio | 45% across 40+ stocks | 25% |
| Sector profile | Several sectors | Some common sector exposure |
Portfolio B has a higher stated concentration at the top end. Its top three positions also account for 35%, which means the effect of a few major holdings could be more significant.
Portfolio A has 55% in its top 10, with the largest position at 8%, while the remaining 45% is spread across 40+ stocks.
These figures can help an investor understand portfolio structure. They do not, by themselves, establish which portfolio has the lower overall risk.
Sector Concentration Matters
Sector exposure deserves separate attention.
Suppose a fund has 10 major stocks but those stocks are spread across several sectors. The fund still has concentration by stock, but its sector exposure may be less concentrated.
Now suppose another fund has 30 stocks, but a large part of the portfolio consists of companies from one industry. The second fund has more stocks but may still face a strong common risk.
The investor should therefore ask two separate questions.
The first question is: “How much of the fund is held in its largest stocks?”
The second question is: “How much of the fund is exposed to the same economic sector or factor?”
These questions address different forms of concentration.
Market Capitalisation Also Matters
The market-cap mix can also change the risk profile.
Large-cap, mid-cap, and small-cap companies can behave differently during different market conditions. Smaller companies may sometimes experience larger price movements, although this is not a rule that applies to every company or every period.
Therefore, a fund with a concentrated top 10 that consists mainly of large companies may have a different risk profile from a fund with the same top-10 percentage but a large allocation to smaller companies.
The concentration number should thus be read together with the market-cap distribution.
The Largest Holding Deserves Attention
The largest individual holding is another useful measure.
In the first example, the largest holding is 8%.
An 8% position means that the performance of that single company can affect the fund, but the company does not represent the majority of the portfolio.
That is different from a portfolio where one security represents a much larger share.
Again, there is no single percentage that can establish whether a fund is suitable or unsuitable for a particular investor. The significance of the position depends on the fund’s mandate, its other holdings, the type of security, and the broader market environment.
Look at the Fund as a Whole
A proper risk review should therefore consider several measures together.
| Measure | What it can show |
|---|---|
| Top 10 percentage | Overall stock concentration |
| Top 3 percentage | Dependence on a few major positions |
| Largest holding | Single-stock exposure |
| Sector concentration | Exposure to common industry risks |
| Market-cap mix | Exposure to large-, mid-, and small-cap stocks |
| Historical volatility | Past variation in fund value |
| Historical drawdowns | Past falls from a high point |
| Stock overlap | Similar exposure across an investor’s other funds |
None of these measures should be treated as a standalone answer.
The last point is particularly relevant for investors who own several mutual funds.
Overlap Can Create Hidden Concentration
An investor may own three or four different funds and believe the portfolio is diversified because the fund names are different.
However, the same company may appear among the top holdings of several funds.
For example, one fund may hold Company A at 8%, another may hold it at 6%, and a third may hold it at 5%. The investor’s total exposure to Company A would then be higher than the exposure shown in any single fund’s factsheet.
The same issue can occur at the sector level.
Several funds may have different names and different stated strategies but still hold many companies from the same sector.
For this reason, concentration should sometimes be assessed at the investor’s total portfolio level, rather than only at the individual-fund level.
What Investors Should Not Assume
A few assumptions can create confusion.
A “low risk” label does not mean zero risk.
A diversified fund does not mean guaranteed protection from losses.
A high top-10 concentration does not automatically mean that a fund is unsafe.
A low top-10 concentration does not automatically mean that a fund is safe.
A larger number of stocks does not automatically produce better diversification.
Past lower volatility does not guarantee lower future volatility.
These distinctions are important because investment outcomes can change with market conditions.
A Practical Analytical Framework
A simple way to review a fund is to start with its top 10 holdings and then move outward.
First, check the percentage held by the top 10.
Second, check the percentage held by the top three.
Third, check the largest single position.
Fourth, examine the sectors represented by the largest positions.
Fifth, examine the market-cap mix.
Sixth, look at historical volatility and drawdowns.
Seventh, compare the fund’s holdings with the investor’s other funds.
This approach gives a more complete picture than the Risk-o-meter or the top-10 percentage alone.
Conclusion
A mutual fund can have a “low risk” classification even when its top 10 holdings account for a significant share of its portfolio. There is no necessary contradiction between the two.
The central point is that concentration risk and total portfolio risk are not the same thing.
A fund with 55% in its top 10 holdings, an 8% largest position, and the remaining 45% spread across 40+ stocks may have a different risk profile from a fund with 75% in its top 10 and 35% in its top three.
The second structure shows greater stated concentration. If several major positions also have common sector or business exposure, the concentration issue may become more important.
However, those figures alone do not establish the overall risk of either fund.
For a meaningful assessment, an investor should consider the fund’s stock concentration, sector exposure, market-cap mix, historical volatility, historical drawdowns, and overlap with other investments.
Most importantly, “low risk” should not be understood as “low chance of loss” in an absolute sense. It is a risk classification, not a guarantee.
The most useful question is therefore not simply, “Is this fund low risk despite its concentrated top 10?”
A more complete question is:
“What risks does this concentration create, what other risks does the portfolio carry, and how have those risks affected the fund in different market conditions?”
That approach allows the portfolio structure and the stated risk category to be assessed together, without treating either one as a complete measure of investment risk.
