Paris Stock Exchange: The Complete Guide to Euronext Paris

The Paris Stock Exchange is the benchmark financial center of the eurozone for French-speaking investors: it is where LVMH, TotalEnergies, Sanofi and Airbus are listed, where the CAC 40 is calculated, and where most French savers invest, directly or through PEAs and life insurance. Operated by Euronext Paris, the Paris market is now the French arm of a group that links Paris, Amsterdam, Brussels, Milan, Madrid, Lisbon, Oslo and Dublin. This guide covers everything you need to know: how it works, indices, trading hours, PEA and SRD eligibility, fees, taxation and the role of the Paris stock exchange in financing the French economy.

What Is the Paris Stock Exchange? History and How It Works

Stock trading in Paris has a long history: Parisian stockbrokers organized themselves as early as the 18th century, and the Palais Brongniart, the “Palais de la Bourse”, hosted open-outcry trading for nearly two centuries, until the 1988 reform abolished the brokers’ guild and opened the market to competition. The Paris Bourse was then privatized and computerized, and in 2000 it merged with Amsterdam and Brussels to create Euronext, the first pan-European stock exchange. Today, Euronext Paris is a subsidiary of the Euronext group, itself listed on the stock market, which runs the French regulated markets: shares, bonds, ETFs, trackers and derivatives.

Companies wishing to list in Paris join Eurolist, Euronext’s regulated market, organized into compartments by market capitalization (A for large caps, B for mid caps, C for small caps). Alternext, now Euronext Growth, welcomes growing SMEs with lighter disclosure requirements, and Euronext Access completes the line-up for the smallest companies. Finally, the Paris market hosts Euronext Farm to Fork and dedicated sector segments (technology, real estate, convertible bonds), a sign of its growing specialization.

Paris Stock Exchange Indices: From the CAC 40 to the CAC Mid & Small

The CAC 40, the Flagship Index

The CAC 40 brings together the 40 largest market capitalizations on Euronext Paris, weighted by free-float market capitalization, with a cap on each stock’s weight so that no single stock dominates the index. Its composition is reviewed regularly by a committee of experts, the Conseil scientifique des indices, which adds and removes stocks based on size, liquidity and free float. It is the index most followed by the French media and the benchmark for the main Paris-listed derivatives and ETFs: our dedicated page on the CAC 40 explains how it is calculated, its composition and its history.

SBF 120, CAC Next 20 and the Size Indices

Several complementary indices revolve around the CAC 40. The SBF 120 adds the next 80 market capitalizations to the flagship index’s stocks: it is the benchmark for many fund managers because it covers most of the trading in Paris with high liquidity. Our SBF 120 page compares its long-term performance with the CAC 40. The CAC Next 20 groups the stocks “waiting” to potentially join the CAC 40; the CAC Mid 60 and CAC Small cover mid and small caps, which are often more domestic and cyclical. All of them are calculated as price indices and total return indices (dividends reinvested), and the gap between the two shows how much dividends weigh in French stock market returns.

Sector Indices

Euronext also publishes CAC sector indices (banks, real estate, technology, healthcare and more), with the CAC Technology index gaining importance as digital companies have listed. At European level, the Euro Stoxx 50, which combines Paris, German, Dutch and Italian stocks, serves as the benchmark for the major eurozone funds.

Paris Stock Exchange Trading Hours

Euronext Paris trades continuously Monday to Friday. A pre-opening phase collects orders from 7:15 am to 9:00 am without executing any trades; at 9:00 am, an opening auction sets the first price for each stock; continuous trading runs until 5:30 pm, with two intraday auctions (12:00 pm for certain stocks); finally, a closing auction from 5:30 pm to 5:35 pm concentrates a significant share of daily trading, as many indices and funds are calculated on the closing price. The market is closed on French public holidays (January 1, May 1, December 25, etc.) and publishes its official calendar each year. To compare these hours with other world markets, our stock market hours page puts Paris, New York, Tokyo and London in the same table.

How to Invest on the Paris Stock Exchange

PEA, Brokerage Account and Life Insurance

The Paris Stock Exchange is French savers’ home market, and France’s tax-advantaged accounts were designed around it. The PEA (Plan d’Épargne en Actions) accepts shares of European companies listed in Paris (and European ETFs): after five years, gains are exempt from income tax, with only social charges still due. The standard brokerage account (compte-titres ordinaire), covered on our brokerage account page, gives access to all stocks with no deposit cap, but with standard taxation (30% flat tax or the progressive scale). Finally, life insurance (assurance-vie) and the PER retirement plan let you invest in euro-growth funds or unit-linked funds backed by French equities, each with their own tax advantages.

The Deferred Settlement Service (SRD)

The most liquid Eurolist stocks are eligible for the SRD, which lets you buy on credit with partial cover (moderate leverage) and sell short within a regulated framework. Settlement takes place at the end of the trading month, creating expiry effects, the famous “SRD Thursdays”, that punctuate the Paris calendar. The SRD requires rigorous risk management: potential losses can exceed the initial stake.

Investment Fees

French online brokers charge very low fees for Paris orders, often less than one euro per order, plus any custody fees and subscriptions. IPOs open to retail investors through their brokers, automatic investment plans and PEA account fees complete the economics of a Paris portfolio, one of the cheapest in Europe.

Dividends and French Taxation

Large Paris-listed companies pay most of their dividends between April and June, after the annual general meetings that approve them, a calendar that shapes cash flow for income investors. For taxes, two regimes coexist in a standard brokerage account: the flat tax (PFU) of 30% (12.8% income tax + 17.2% social charges) on dividends and capital gains, or, by option, the progressive income tax scale with a 40% allowance on dividends and holding-period allowances on capital gains, an option to simulate case by case. In a PEA, reinvested dividends are not taxed as long as they stay in the plan; withdrawals after five years are exempt from income tax on gains, with social charges still due at the prevailing rate. This treatment is one of the strongest arguments in favor of the Paris Stock Exchange for a French resident: nowhere else is the tax wrapper so directly aligned with the home market.

The Largest Companies Listed in Paris

The face of the Paris Stock Exchange has changed over twenty years: luxury and technology stocks now weigh as much as banks and energy. The CAC 40’s largest historical market capitalizations thus include LVMH and Hermès (luxury), TotalEnergies (energy), Sanofi (healthcare), Airbus (aerospace), L’Oréal (consumer goods), the big banks (BNP Paribas), insurers (AXA) and utilities (Engie, and EDF before its renationalization). This diversity makes the CAC 40 more defensive and more dividend-oriented than most of its European peers: the dividend yield of large French companies has historically been among the highest in the eurozone.

Why the Paris Stock Exchange Matters for Investors

Three reasons explain Paris’s unique place in French-speaking investors’ portfolios. First, domestic taxation: the PEA, life insurance and the PER were built around French and European markets, a cumulative advantage over the long term. Second, liquidity and regulation: Euronext is a leading regulated market, supervised by the AMF and the Banque de France, with standardized settlement times. Finally, the index’s unique composition: the CAC 40 provides exposure to global luxury, the energy transition, healthcare and finance, a profile that neither the DAX nor the FTSE 100 replicates exactly. For a beginner investor, the Paris Stock Exchange remains the most natural entry point: same hours, same currency, same tax system.
