The FTSEurofirst 300 tracks 300 large developed-European companies. Learn how selection, free-float weighting, currencies, and returns work.
The FTSEurofirst 300 Index is a broad European equity benchmark made up of 300 large companies from developed European markets. Companies are selected by full market value from the eligible FTSE Developed Europe universe, but their index weights reflect investable, or free-float-adjusted, market capitalization. It is broader than a euro-area-only index and includes markets such as the United Kingdom and Switzerland.
The index is designed to represent the performance of large companies resident and incorporated in developed European countries. An eligible security must first be a constituent of the FTSE All-World Developed Europe Index. FTSE Russell then ranks eligible companies by full market value and selects the largest 300, subject to the index rules.
This two-stage process matters:
Calling the index simply “the 300 largest European stocks” omits both eligibility rules and the distinction between a company’s total equity value and the portion available to public investors.
The official methodology can be summarized as:
where:
The divisor is adjusted when required so that constituent changes and qualifying corporate actions do not create an artificial jump in the index level. Index points are a measurement scale, not a euro amount invested.
Assume a simplified three-company European index. All values are converted to euros before weights are calculated.
| Company | Full market value | Investability factor | Investable market value | Weight |
|---|---|---|---|---|
| A | EUR 120 billion | 50% | EUR 60 billion | 33.33% |
| B | EUR 90 billion | 100% | EUR 90 billion | 50.00% |
| C | EUR 60 billion | 50% | EUR 30 billion | 16.67% |
| Total | EUR 270 billion | EUR 180 billion | 100% |
Company A ranks first by full market value, yet Company B receives the largest weight because all of B’s shares are treated as investable in this illustration.
If A gains 1%, B loses 2%, and C gains 3%, the simplified one-period price return is:
The example excludes dividends, taxes, currency movements, corporate actions, constituent changes, and rounding. It illustrates weighting, not an expected return.
The index is calculated in euros and published in euros and other currencies. This does not eliminate currency exposure. Currency enters the analysis in two different places:
Suppose the euro-denominated index gains 6% while the euro falls 4% against an investor’s home currency. A simplified unhedged home-currency return is:
Actual fund returns can also differ because of fees, withholding taxes, tracking error, hedging, trading costs, and the product’s chosen index series.
The current FTSEurofirst ground rules schedule quarterly reviews in March, June, September, and December. Review data are taken before the effective date, and changes normally become effective on the trading day after the third Friday of the review month.
Between reviews, mergers, takeovers, delistings, share changes, free-float changes, and other corporate events may alter the index. Historical analysis should therefore use the constituents, shares, investability factors, exchange rates, and divisor applicable on the measurement date.
| Index | Main coverage | Approximate constituent count | Main analytical use |
|---|---|---|---|
| FTSEurofirst 300 | Developed European large companies | 300 | Broad developed-Europe benchmark |
| FTSE 100 | Large companies listed in London that meet FTSE rules | 100 | UK large-cap benchmark |
| CAC 40 | Large, liquid shares listed in Paris | 40 | French large-cap benchmark |
| DAX | Major companies listed in Germany that meet index rules | 40 | German blue-chip benchmark |
The FTSEurofirst 300 provides broader company and country coverage than these national indexes. Broader coverage does not guarantee lower risk: market-cap weighting can still produce meaningful concentration in the largest companies, countries, and sectors.
FTSE Russell calculates capital and total-return versions of the index series.
| Series | Share-price movements | Cash distributions | Best used for |
|---|---|---|---|
| Capital, or price, index | Included | Excluded | Comparing quoted market-price movement |
| Total-return index | Included | Reinvested under methodology rules | Comparing dividend-inclusive investment performance |
Comparing a dividend-reinvesting portfolio with the capital index understates the benchmark return. Analysts should also identify the currency and any gross, net, or tax treatment attached to the exact series being used.
The index is not a direct measure of European gross domestic product. Large listed companies can earn substantial revenue outside their country of incorporation, private businesses are excluded, and stock prices reflect expected future cash flows and valuation changes rather than current output alone.
