The Indexeuro PX4 is distinguished by its willingness to represent the entire variety of the French stock market, unlike more limited indices such as the CAC 40. Its official name remains SBF 120, but the PX4 code is used in quotations – these two references are frequently found in the specialized press or on investment platforms. According to the current calculation methods, it is presented in different versions: "GR" (Growth Return, Reinvested Dividends) and "NR" (Net Return, Reinvested Net Tax Dividends), giving an accurate view of growth or return based on the inclusion of dividends. The Indexeuro PX4 is therefore used as a benchmark, both by fund managers and individuals. This helps to better organize their stock exchange allowance. A professional in the sector recently mentioned how much he brought to investors wishing to diversify.

It is relatively common for a beginner investor to question: "Is it SBF 120 or CAC 40 that I have to monitor first?" The major asset of the PX4 is based on its wide range, encompassing both the CAC 40 heads display, the next 20 rising values and the Mid 60 dynamic midcaps. This makes it possible to more accurately translate the mosaic of the national economy. The presence of companies such as Safran, LVMH or Eiffage (whose shares sometimes oscillate from 122 to 631€) testifies to their indisputable weight in markets.

How is it composed and calculated?

Better understanding the structure of the Indexeuro PX4 (SBF 120) gives the keys to understand how its fluctuations are closely monitored. Especially when measuring the impact on its portfolio. Each annual review may see some values incorporate or leave the index, but the method used remains sophisticated.
120 leading French values
From an organisational point of view, the index is constructed in a clear way: it is 120 enterprises among the most liquid and influential of Euronext Paris. This group brings together CAC 40 (historical heavyweights), CAC Next 20 (future leaders), and CAC Mid 60 (growth midcaps). A glance is enough to cross great names like Airbus, LVMH, Kering, Capgemini or Société Générale. The integration of companies from different sectors feeds the dynamism of the index, according to some analysts in the sector.
Here are some of the highlights of his composition:
- Weight: The importance of each company in the index depends on its market capitalisation (the higher a company is valued, the higher its weight).
- Entry criteria: a sufficient float, regular exchanges and an uninterrupted quotation on Euronext Paris remain necessary.
- Update: the selection to stick to the reality of the market (some companies join or exit the SBF 120 according to the cycles).
- Variations: the so-called "GR" (reinvested raw dividends) is often preferred to judge performance over the long term.
In the spring of 2024, the daily volume exchanged on these values averaged EUR 1.4 billion. A figure that has already impressed more than one in its first steps on the stock exchange.
Sector balance well studied
Far from being just a gallery of champions, the SBF 120 also offers a real sectoral distribution. Compared with CAC 40, often dominated by luxury and finance, the PX4 integrates more major players from health, technology, industry and consumption. This creates a diverse fabric of values, and brings increased resistance to a shock that would affect only one sector. Some observers see this sectoral balance as one of the major strengths of the index.
