Open-ended funds provide a way to invest through a professionally managed portfolio with subscriptions and redemptions under the fund's dealing terms. Portfolios may include equities, bonds, cash and other permitted instruments.
Published portfolios and performance make it possible to ask clear questions about the manager’s work and the value delivered after fees. Comparing those choices with relevant market references can support a more informed fund-selection process. This article combines that framework with our historical international index study, identified by its 2025 data cut-off.
Start with the portfolio
Compare asset allocation, the largest positions, sectors, geography and currency exposure. Include cash and any relevant derivatives when interpreting the investment strategy.
Two funds investing in Portuguese securities can implement different mandates. Holdings and their changes over time help explain those differences. Underlying exposure analysis also shows when different funds share exposure to the same issuer or activity.
Read historical performance consistently
| Comparison field | Consistent treatment |
|---|---|
| Period | Use the same start and end dates. |
| Currency | Compare in the same currency or explain the currency difference. |
| Return | Distinguish cumulative and annualised returns. |
| Distributions | Identify whether distributions are reinvested or excluded. |
| Share class | Match performance to the class and its fee terms. |
| Costs | Separate charges reflected in NAV from investor-level charges. |
A NAV-based return normally reflects costs accounted for within that NAV. Deducting the same management fee again would count that cost twice. Entry, exit, custody or other separately charged costs may affect the investor's own result.
International comparisons: what the earlier research adds
Comparing Portuguese equities with other markets gives context to the manager's opportunity set. It can also highlight what a fund adds through security selection, asset allocation and implementation. The useful question is how the chosen fund uses that opportunity set, at what cost, rather than whether an index determines the outcome of every fund investing in Portugal.
Historical market paths, 2015–2025
The earlier article compared the PSI with Spain's IBEX 35, France's CAC 40, the UK's FTSE 100 and the US S&P 500. The original chart is retained below as a historical exhibit, prepared in November 2025. It shows the chosen decade's different paths; it is not a forecast or an assessment of an individual fund.
The S&P 500 shows the strongest cumulative increase in this particular chart, while the European indices follow different paths. Sector weights, dividends and currencies contribute to the differences. For an EUR-based comparison, identify the return series and currency treatment before drawing conclusions. S&P Dow Jones Indices' methodology distinguishes price, total-return and currency-adjusted calculations.
The annual chart makes a useful point about fund research: relative performance changes from year to year. The PSI records both positive and negative years, with a strong positive observation in the displayed 2025 year-to-date period. Looking across periods helps assess whether a manager's results are associated with market exposure, portfolio choices or both.
Five-year windows: a historical research sample
The original study described 500 randomly selected, overlapping five-year windows within 31 October 2015–31 October 2025. This is resampling of one historical dataset, not 500 independent market histories. Study cut-off: 31 October 2025. The figures below describe that historical dataset and are not a 2026 performance update.
| Index | Annualised return: reported median | Reported annual volatility | Reported maximum drawdown magnitude |
|---|---|---|---|
| PSI | 5.5% | 17.8% | 33.8% |
| IBEX 35 | 2.5% | 20.6% | 39.4% |
| S&P 500 | 14.3% | 21.2% | 33.9% |
| CAC 40 | 8.5% | 20.5% | 38.6% |
| FTSE 100 | 2.9% | 17.6% | 35.0% |
Source: figures reported in Nomera Capital's original November 2025 study. These are index-study outputs, not net fund returns. The preserved exhibits do not establish a harmonised currency/dividend treatment or a complete reproducible specification of the sampling and ratio assumptions; use them as historical context rather than a precise ranking of investable alternatives.
In the reported sample, the PSI's median annualised return was above the IBEX 35 and FTSE 100 and below the CAC 40 and S&P 500. Its reported volatility was close to the FTSE 100 and below the other three references. This is more informative than labelling the Portuguese market categorically strong or weak: the period, benchmark definition and actual fund all matter.
Read the path as well as the endpoint
A five-year annualised return compresses the path into a single figure. The original drawdown chart adds another perspective by showing the largest peak-to-trough falls observed inside the sampled windows. A drawdown is measured from a previous peak; it is not necessarily the loss from an investor's purchase price and does not establish when or whether recovery occurs.
For fund comparison, look at return, volatility and drawdown together, over aligned dates and for the exact share class. Allocation to cash, bonds, derivatives or other holdings can make a fund's path different from an equity index. Neither daily pricing nor the absence of daily quotations establishes investment quality by itself.
What risk-adjusted measures add
Sharpe and Sortino relate returns to different measures of variability; Omega uses a selected return threshold; Sterling relates returns to drawdown; VaR and CVaR describe specified parts of a loss distribution. They help organise questions about how a result was achieved.
Use several measures alongside the portfolio and the manager's stated process. No single ratio captures the full investment proposition, liquidity terms or fee structure.
Choosing funds: connect the manager's work with the fee structure
Open-ended funds offer a way to combine professional portfolio management, periodic reporting and access under documented dealing terms. Those features make comparison practical. The same broad market exposure can be implemented through different stock weights, cash positions, mandates, trading decisions and share-class terms.
A focused research process asks:
- What is the mandate? Identify the mix of equities, bonds, cash and other instruments, and the benchmark that best represents it.
- What does the manager do differently? Examine holdings, changes in allocation, position sizes, investment process and portfolio overlap.
- What is the relevant track record? Compare aligned periods and the same strategy, team and share class, separating a fund's history from the manager's wider experience.
- What reaches the investor after costs? Read recurring expenses, transaction costs, entry and exit charges and any performance fee together.
- What are the access and dealing terms? Compare the exact class, minimum, subscription conditions and investor-access requirements alongside liquidity and any immigration obligations.
An active fund can justify a different fee through the service, process and outcomes it delivers. A lower headline fee is one consideration; the evidence should show the total cost and what is provided in return. Comparing the accessible share classes is especially useful because investors in the same portfolio can face different terms.
A simple illustration of the cumulative effect of fees
Assume a hypothetical investment of €100,000, a 7% gross annual return for five years, and an annual charge applied at year-end to the post-growth value. There are no other fees, taxes, contributions or distributions in this example.
| Illustrative annual charge | Value after five years |
|---|---|
| 0% reference | €140,255 |
| 1% | €133,381 |
| 2% | €126,780 |
Calculation: €100,000 × [1.07 × (1 − annual charge)]⁵, rounded to the nearest euro. These are hypothetical assumptions, not a return estimate for Portuguese equities or any fund. Actual fees can accrue on a different basis.
The example isolates cost compounding; it does not assume that two managers will deliver the same gross result. The SEC's investor guidance on fees explains why both the charge and the resulting reduction in invested capital matter over time.
For an actual fund, start with its published NAV and distribution methodology. Costs already reflected in that series should not be deducted again. Add separately charged costs only where applicable. For a performance fee, check the hurdle, high-water mark, crystallisation, calculation base and class terms rather than relying on the percentage alone. Our fund terms and fees guide provides a comparison framework.

Use the PSI as context
The PSI provides a reference for Portuguese listed equities. Euronext renamed PSI 20 to PSI with effect from 21 March 2022. The PSI20 ticker was retained, so historical names and data identifiers should be distinguished from the current index name. The index does not represent every open-ended fund's asset allocation or mandate. A bond or mixed fund should be interpreted in the context of its own exposures.
Distinguish a price index, which excludes dividends, from a total-return series. A return gap can reflect dividends, cash, fees, allocation, currency or other differences as well as investment decisions. It should not automatically be labelled manager skill.
Historical comparisons describe the period measured. They do not establish expected future returns or probabilities for a new investor.
Research the companies behind the portfolio
The earlier article also examined listed-company fundamentals. That perspective remains useful when connected to the fund's actual holdings. Use current, dated statements and explain whether a multiple uses trailing or forecast earnings rather than carrying forward an old share-price snapshot.
| Research lens | Examples of evidence | How it helps interpret a holding |
|---|---|---|
| Valuation | P/E, enterprise value / EBITDA and cash-flow measures | Connect the price paid with the business's earnings and assets; compare appropriate peers. |
| Operating quality | Revenue, margins, return on invested capital and cash conversion | Examine the economics behind reported growth and profitability. |
| Financing | Net debt, debt maturity, interest coverage and liquidity | Understand the funding structure and refinancing needs. |
| Distributions | Dividend policy, payout and free cash flow | Assess how distributions are supported by the business. |
| Portfolio role | Position size, sector, geography and overlap | Explain why the holding contributes to this fund's strategy. |
A lower valuation multiple does not, by itself, establish a better investment; accounting, sector and business-model differences matter. Equally, portfolio overlap does not make two funds interchangeable: weights, cash, trading, class terms and fees can produce different investor outcomes.
Our proprietary models of manager decisions
Stock Picking Ability
Our fund-level model examines whether inferred portfolio decisions improved subsequent returns relative to retaining the previous positions. It includes the cash used or released and separates estimated subscriptions and redemptions.
Downside Protection
This model examines whether inferred decisions reduced subsequent peak-to-trough losses. The analysis includes the treatment of inferred changes in futures exposure described in the methodology.
Published assessments use a five-year history and three-month outcomes. The scale runs from 0 to 100, with 50 as the neutral point: favourable and adverse measured effects balance. Scores are not win rates, probabilities, forecasts or regulatory risk indicators.
The methodology is experimental. Decisions are inferred from monthly holdings, outcomes overlap, trading costs are not deducted and futures effects use a PSI proxy. Each score should be read with its date and methodology. An unavailable score is not zero.
Read the published methodology alongside the results. These assessments concern decisions within a fund and are separate from the manager company's financial profile.
Flows, size and portfolio changes
Changes in fund size can reflect performance, subscriptions, redemptions and other effects. Changes in a holding's value can reflect both market prices and changes in quantity.
Our market insights distinguish estimated net flows from portfolio rebalancing. Aggregates for funds classified as Golden Visa include their investors generally; they should not be presented as capital exclusively from Golden Visa applicants. Umbrella and compartment reports must not be counted twice.
Liquidity and access
Compare dealing frequency, notice, settlement and redemption conditions. Keep the ability to redeem separate from an investor's immigration obligations. Neither an open-ended nor a closed-ended structure is inherently preferable for every investor.
