How to Trade the CAC 40: A Complete CFD Guide

The CAC 40 is France's headline equity benchmark and the most direct way to take a single position on the French market. One CFD trade on the index gives exposure to 40 of the largest and most actively traded companies listed in Paris, without buying individual shares.

This guide covers what the index contains, why its sector mix makes it behave unlike any other European benchmark in the Vanto range, what actually drives it, and the concrete contract mechanics of the CAC40 CFD on Vanto. If you are new to index CFDs, the foundations are covered in what indices trading is and how it works and in CFD index trading mechanics; this guide assumes them and stays on the French index.

What Is the CAC 40?

The CAC 40 is the benchmark stock index of Euronext Paris, tracking 40 of the largest and most actively traded companies drawn from the 100 biggest listings on the French market.

The name is an abbreviation of Cotation Assistee en Continu, French for continuous assisted quotation, a reference to the electronic trading system introduced when the index was created. The index was set with a base value of 1,000 on 31 December 1987 and began publication in mid-1988. It is calculated and maintained by Euronext, which also operates the exchange itself.

Two construction points matter more to traders than the headline definition. First, the CAC 40 is a price index: the published number reflects share prices only and excludes dividends. Euronext publishes a separate gross total-return variant that reinvests them, but the figure quoted in market commentary and used for CFD pricing is the price index. Second, the index is free-float weighted with an individual cap, so the influence of any one company is deliberately limited. Composition is reviewed quarterly by an independent index committee, using free-float market capitalisation and traded turnover as the main selection criteria.

Eligibility follows the listing venue rather than the passport of the company. Constituents are companies listed on Euronext Paris, which includes a small number of groups whose legal headquarters sit outside France. The index measures the Paris market, not the French economy, and the distinction turns out to matter a great deal once you look at where constituent revenue actually comes from.

CAC 40 Composition: Why Luxury Dominates

The CAC 40 carries the heaviest luxury-goods concentration of any major European benchmark, alongside large positions in aerospace, energy, pharmaceuticals, industrials, and banking.

The luxury complex includes LVMH, Hermes, L'Oreal, Kering, and EssilorLuxottica. LVMH and Hermes have traded places as the largest listed company in France by market capitalisation, and both sit at or near the top of the index by weight. No other European benchmark in the Vanto range has anything comparable: the DAX 40 is weighted toward industrials, software, and insurance, the FTSE 100 toward energy, mining, and pharmaceuticals, and the IBEX 35 toward banks.

Outside luxury, the index holds Airbus in aerospace, TotalEnergies in oil and gas, Sanofi in pharmaceuticals, Air Liquide in industrial gases, Schneider Electric and Legrand in electrical equipment, Safran in aero engines, and three large banks in BNP Paribas, Societe Generale, and Credit Agricole. Weights move with prices and with each free-float revision, so any specific percentage is a snapshot rather than a fixed property of the index.

Why the 15% cap changes the index's behaviour

Euronext caps each CAC 40 constituent at 15% of index weight, which limits how far a single dominant company can drive the benchmark.

The capping factor is applied at review rather than continuously, so a fast-rising constituent can drift above the ceiling between reviews before being pulled back. The practical effect is a middle position among European benchmarks. The DAX 40 applies a tighter 10% ceiling at each quarterly review. The IBEX 35 applies no individual cap at all in its headline construction, which is why a single Spanish bank or Inditex can exert an unusually direct pull on that index.

For a trader the consequence is about how much single-name event risk reaches the index price. An earnings surprise at the largest CAC 40 constituent transmits with real force, but not with the full unconstrained weight it would carry in an uncapped index. The three benchmarks therefore sit on a spectrum: DAX 40 most diluted, CAC 40 intermediate, IBEX 35 most concentrated.

The China Connection: A French Index With Asian Demand Exposure

The CAC 40's largest constituents earn a substantial share of revenue outside Europe, and Chinese consumer demand is the single most important external channel into the index.

This is the feature that most often surprises traders approaching the French index for the first time. LVMH reports roughly 30% of revenue from its Asia excluding Japan segment, in which China is the largest single market. Kering carries comparable exposure. L'Oreal sells heavily into Chinese beauty demand. The pattern extends past luxury: Airbus depends on Asian carrier order books, and the industrial names in the index are geared to global capital expenditure rather than to French construction.

The consequence is that CAC 40 pricing can respond to developments that have nothing to do with France or the eurozone: Chinese retail sales and consumer confidence, property-sector stress in China, travel and tourism flows through duty-free channels, Chinese stimulus announcements, and the renminbi exchange rate. A trader who models the CAC 40 purely as a bet on the French economy is working with an incomplete picture.

The parallel with the IBEX 35 is instructive and the mechanism is entirely different. The Spanish index carries emerging-market exposure through bank and telecom operations in Latin America, so its external channel is banking earnings and regional currencies. The French index carries its external exposure through consumer demand for discretionary goods, so its channel is retail spending and travel. Both are European indices with a large non-European determinant; neither one behaves like the domestic economy whose flag it flies.

This exposure runs in both directions. It is a source of return dispersion relative to European peers, and it is a source of risk that a purely European analysis would not capture.

CAC 40 and Euro Stoxx 50: Overlapping, Not Diversifying

A CAC 40 position and a Euro Stoxx 50 position hold many of the same companies, so running both is closer to doubling one exposure than to spreading risk across two.

The Euro Stoxx 50 selects blue chips from across the eurozone, and French companies form its largest or second-largest country block. As of the September 2025 review it contained 15 French constituents out of 50, with France and Germany together representing roughly 65% of index capitalisation. The French names that qualify are precisely the largest CAC 40 constituents, which are also the ones carrying the most CAC 40 weight after capping.

Three practical points follow.

Correlation is structural, not incidental. The two indices move together because they hold the same shares, not because of a statistical tendency that might break down. Diversification arguments that treat them as separate instruments do not survive contact with the constituent lists.

Position sizing should account for the overlap. A trader long both instruments is carrying concentrated exposure to a small group of French mega-caps twice over. Margin requirements are calculated per position and do not net the shared economic exposure.

Divergence has identifiable sources. When the two do separate, the reason is usually the part of each index the other does not hold: German industrials, Dutch semiconductors, and Italian banks on the Euro Stoxx 50 side, and the smaller French constituents that fall below Euro Stoxx eligibility on the CAC 40 side. French domestic political risk also hits the CAC 40 harder because it is a larger share of that index.

CAC 40 Trading Hours Explained

The Paris cash market trades continuously from 09:00 to 17:30 CET, preceded by a pre-opening phase from 07:15 and followed by a closing auction that runs to 17:35.

The 07:15 to 09:00 window is an order-accumulation phase in which orders are entered and amended but nothing executes. At 09:00 an auction algorithm crosses accumulated supply and demand to set the official opening price, which also establishes the opening level of the CAC 40. Continuous trading then runs for eight and a half hours without a lunch break. At 17:30 the order book moves into a closing auction, and the official close is struck at 17:35. That final crossing carries heavy volume, because index funds and benchmark-tracking accounts need to transact at the official closing price.

Paris operates on Europe/Paris time, which is UTC+1 in winter and UTC+2 during summer daylight saving. Frankfurt, Madrid, and Amsterdam share this schedule, so the French, German, Spanish, and Dutch cash sessions open and close together and change clocks on the same dates.

CFD pricing on the index extends beyond the cash session, tracking index futures and pre-market activity outside 09:00 to 17:30 CET. Liquidity is deepest during the cash session and thins outside it, which is when spreads are typically at their widest.

The Euronext holiday calendar is shorter than many traders expect. The exchange closes for a handful of full days each year, typically New Year's Day, Good Friday, Easter Monday, 1 May, and the Christmas holidays, and it runs shortened sessions on 24 and 31 December with an early close in the early afternoon. It does not close for most French public holidays. Bastille Day on 14 July, Victory in Europe Day on 8 May, Assumption on 15 August, and the November holidays are all ordinary trading days in Paris. A trader assuming that a French national holiday means a closed market will be wrong most of the time, and the current year's schedule should be confirmed against the exchange's published calendar rather than inferred.

What Moves the CAC 40?

The CAC 40 responds primarily to global luxury demand, European Central Bank policy, French political and fiscal developments, the aerospace and energy cycles, and broad risk sentiment.

Luxury demand and the Chinese consumer. Because the luxury complex carries so much index weight, quarterly sales updates from LVMH, Hermes, Kering, and L'Oreal function as index-level events rather than single-stock events. Chinese consumption data, travel-retail volumes, and currency moves that change the price of European goods for Asian buyers all reach the index through this channel.

Monetary policy. ECB decisions affect discount rates, bank margins, and the euro exchange rate, all of which reach French equity valuations. The mechanism by which central bank policy transmits into asset prices is covered in depth in the central banks guide; this section describes the index-specific channel rather than repeating the general mechanism.

French politics and the sovereign spread. France's fiscal position and parliamentary arithmetic reach the index mainly through its banks, which hold French government debt and fund themselves in the same market. The spread between 10-year French OAT yields and German Bund yields is the market's live price for that risk. When President Macron called snap parliamentary elections in June 2024, that spread widened to around 80 basis points, its widest since the euro sovereign debt crisis, and the CAC 40 fell close to 10% over the following weeks, with banking stocks leading the decline. The spread has since traded persistently wider than its pre-2024 average. For a trader the point is not the historical episode itself but the transmission path it revealed: French political headlines show up first in the bond spread and then in the bank constituents.

Aerospace and energy cycles. Airbus and Safran tie the index to aircraft order books, delivery schedules, and airline capital expenditure. TotalEnergies ties part of it to crude oil and gas prices, which gives the CAC 40 a partial commodity linkage that the DAX 40 largely lacks.

The euro exchange rate. With most large constituents earning heavily abroad, euro strength reduces the euro value of foreign revenue and euro weakness increases it. This is the same export-sensitivity channel that operates in the German index, and in the CAC 40 it works through consumer and aerospace exporters rather than through carmakers.

Broad risk sentiment. Like other European indices, the CAC 40 correlates with global equity risk appetite, with US index futures during the New York overlap, and with the general direction of European equity flows.

Dividends and Index Construction

The CAC 40 is quoted as a price index, so the headline level reflects share price movement only and excludes the dividends paid by its constituents.

This matters when comparing long-run charts across benchmarks. The DAX 40 headline figure is a total-return performance index that reinvests gross dividends into the index level, so its chart combines price appreciation with dividend reinvestment. The CAC 40 headline figure excludes dividends entirely. Two flat charts, one French and one German, therefore do not describe the same underlying investor experience. Euronext publishes a gross total-return version of the CAC 40 for comparison purposes, but it is not the series quoted in market commentary or used for CFD pricing.

For an index-CFD trader this is context rather than income. A CFD on an index does not confer share ownership, and index CFD positions do not receive dividends the way a shareholder does. The relevant consequence is comparative: performance comparisons between the CAC 40 and the DAX 40 are not like-for-like unless the same index variant is used on both sides.

CAC 40 CFD Mechanics on Vanto

The French index CFD on Vanto is listed as CAC40 with the following contract specification:

• Contract size: 1 index unit per lot
• Profit currency: EUR
• Quote precision: 2 decimal places
• Triple swap day: Friday (three days of financing booked to cover the weekend)

Tick value. A quote precision of two decimals and a contract size of 1 mean a 0.01-point move is worth EUR 0.01 per lot and a full 1-point move is worth EUR 1 per lot. Position-sizing arithmetic for index CFDs is set out in the lot size guide.

Spread. The bid/ask spread is the primary execution cost, and Vanto charges zero commission on index CFDs across Standard and Raw account types. Spreads are variable: they are tightest while the Paris cash session is open and widen outside it, particularly overnight and around scheduled releases. Live values can be checked in the trading calculator or in the platform itself rather than relied upon from any single published figure. The mechanics of bid/ask pricing are covered in the spread guide.

What "one lot" actually means across European index CFDs

Because every European index CFD in the Vanto range uses a contract size of 1, the notional value of one lot equals the index level, which means the same lot size represents very different position sizes from one index to the next.

The table below uses live Vanto quotes taken on 10 August 2026 for the five European index CFDs quoted in euro. Index levels change constantly, so treat the figures as an illustration of the ratios rather than as current prices.

One lot of DAX40 is roughly three times the notional exposure of one lot of CAC40, and roughly twenty-four times the exposure of one lot of AEX25, even though all three are quoted in euro with identical contract mechanics and identical tick values of EUR 1 per point. A position size carried across from the German index to the French one without adjustment is therefore materially smaller in risk terms, and the reverse carry is materially larger.

This is a sizing point, not a preference between instruments. Leverage reduces the capital needed to open any of these positions and amplifies both gains and losses on the full notional amount, not on the margin deposited. Margin mechanics, including margin level and stop-out, are covered in the margin guide, and the ratio-to-margin relationship in the leverage guide.

Overnight financing. CAC40 sits at the inexpensive end of the European index range for carrying a long position, with a long-side swap close to the DAX40 figure and a small fraction of the ESP35 debit, while the short side carries a modest debit rather than a credit. Triple swap is booked on Friday. A side-by-side table of published swap values across all seven European index CFDs, with the caveat that these values change, is included in the IBEX 35 guide, and the mechanics of how swap is calculated and applied are covered in the swap guide.

Step-by-Step: Opening Your First CAC 40 Trade in MT5

Opening a CAC40 CFD trade on MT5 involves seven mechanical steps: locating the symbol in Market Watch, opening the New Order dialog, selecting an order type, defining volume, setting Stop Loss and Take Profit, executing, and monitoring the position.

What follows describes the mechanics of placing the order. It does not advise when to enter, which direction to take, or how large the position should be; those are decisions only the individual trader can make against their own risk profile and trading plan.

Step 1. Locate the CAC40 symbol in Market Watch. Open MT5 and look at the Market Watch panel. If CAC40 is not listed, right-click in the panel and select Show All, or type "CAC40" into the search box. Other providers list the French index under codes such as FRA40, FCE, or France 40; on Vanto the symbol is CAC40.

Step 2. Open the New Order dialog. Right-click CAC40 and select New Order, or press F9. Confirm the symbol shown in the order window before proceeding.

Step 3. Set the order type. Choose Market Execution to fill at the current price, or a Pending Order (Buy Limit, Sell Limit, Buy Stop, Sell Stop) to fill only when price reaches a defined level.

Step 4. Define the volume. Enter the lot size. The minimum volume for CAC40 is published in the contract specification on the platform. Volume follows from a position-sizing rule based on account equity and stop distance rather than being chosen arbitrarily, and the notional table above shows why a volume carried over from another index does not represent the same exposure.

Step 5. Set Stop Loss and Take Profit. Enter the price levels for both. A Stop Loss closes the position automatically if price reaches the specified level against you; a Take Profit closes it at a favourable target. Both fields are optional, but a position without a stop remains exposed until it is closed manually.

Step 6. Review and execute. Confirm symbol, volume, order type, and levels, then click Buy by Market or Sell by Market, or Place for a pending order. Confirmation appears in the Trade tab.

Step 7. Monitor the position. Open positions appear in the Trade tab with running profit and loss. Levels can be changed by right-clicking the position and selecting Modify or Delete Order, and the position can be closed early with Close Position.

Working through this sequence on a demo account first lets the order flow become familiar without financial exposure.

Risk Management for CAC 40 CFD Trading

The principal risks in CAC 40 CFD trading are auction gap risk, concentration in a single sector, correlated exposure through the Euro Stoxx 50, political headline risk, leverage amplification, and weekend exposure.

Gap risk at the auctions. The opening price is set by an auction at 09:00 CET and the close by an auction at 17:35, rather than by continuous trading. News arriving while the cash market is closed is absorbed into a single crossing, so the index can open well away from the previous close. A stop-loss order does not guarantee a fill at its level through a gap; it becomes a market order at the next available price, which may be materially worse. The related execution mechanics are explained in the slippage guide.

Sector concentration. The weight sitting in luxury goods means a demand shock in one consumer category reaches the index through several of its largest constituents simultaneously. The 15% cap limits single-name influence; it does nothing to limit sector-level correlation between capped names.

Correlated positions. As set out above, holding CAC 40 and Euro Stoxx 50 positions at the same time concentrates rather than spreads exposure. The same applies, to a lesser degree, to the DAX 40 during broad European risk moves.

Political headline risk. French budget votes, confidence motions, and election announcements have repriced the index quickly and outside scheduled data windows. Because these events are not on an economic calendar in the way a data release is, they arrive without a defined timestamp.

Leverage and position sizing. Leverage amplifies gains and losses on the full notional value. A 1% adverse move on a position taken at 1:20 leverage represents a 20% loss against the margin deposited.

Weekend exposure. A position carried from Friday close to Monday open spans roughly 65 hours during which the cash market cannot be accessed, and triple swap is booked on Friday.

Frequently Asked Questions About Trading the CAC 40

What does CAC 40 stand for?

CAC stands for Cotation Assistee en Continu, French for continuous assisted quotation, a reference to the electronic trading system used on the Paris exchange. The 40 refers to the number of constituents. The index was set at a base value of 1,000 on 31 December 1987.

Is CAC40 the same as the FRA40 or France 40?

Yes. CAC40 is the symbol under which Vanto lists a CFD on the French CAC 40 index. Other providers use codes such as FRA40, FCE, France 40, or F40 for instruments tracking the same underlying benchmark. The naming differs between platforms; the index being tracked does not.

What time does the CAC 40 open and close?

The Paris cash session runs from 09:00 to 17:30 CET, with a pre-opening phase from 07:15 and a closing auction that sets the official close at 17:35. CFD pricing extends outside those hours, tracking futures and pre-market activity, with the deepest liquidity during the cash session.

Is the Paris exchange closed on French public holidays?

Usually not. Euronext Paris closes for only a handful of full days each year and trades normally on most French national holidays, including 14 July. It runs shortened sessions on 24 and 31 December. The current year's calendar should be confirmed against the exchange's published schedule.

Are CAC 40 constituent weights capped?

Yes, at 15% of index weight, applied at review. That ceiling sits between the DAX 40, which caps constituents at 10%, and the IBEX 35, which applies no individual cap in its headline construction.

Does the CAC 40 include dividends?

No. The headline CAC 40 is a price index and excludes dividends. Euronext publishes a separate gross total-return variant that reinvests them, but the price index is the series used in market commentary and for CFD pricing. This is the opposite convention to the DAX 40, whose headline number is a total-return performance index.

Can I short the CAC 40?

Yes. A CFD can be sold as readily as it is bought, which allows a short position on the index without borrowing shares. On Vanto the short side of CAC40 carried a small overnight debit as of 10 August 2026, and swap values change over time; current figures are visible in the contract specification within MT5.

How is the CAC 40 different from the DAX 40?

The CAC 40 tracks 40 Paris-listed constituents as a price index with a 15% cap and a heavy luxury-goods concentration; the DAX 40 tracks 40 German constituents as a total-return performance index with a 10% cap and a heavy industrial and technology weighting. Dividends are reinvested into the DAX 40 headline number and excluded from the CAC 40 headline number, so long-run charts of the two are not directly comparable. The French index also carries far more Chinese consumer-demand exposure. A parallel walkthrough of the German index is available in the DAX 40 guide.

Should I trade the CAC 40 or the Euro Stoxx 50?

That is a decision for the individual trader, but the two are not independent alternatives. Roughly 15 of the Euro Stoxx 50's constituents are French and they are largely the same mega-caps that dominate the CAC 40, so the two instruments share a substantial part of their economic exposure. The Euro Stoxx 50 adds German, Dutch, Italian, and other eurozone names; the CAC 40 concentrates on Paris.

Risk warning. Trading securities, futures, options, and contracts for differences are complex financial instruments that require knowledge and understanding. Prices can fluctuate significantly and securities may become valueless. Investors may incur losses exceeding the potential for profits. Trading on margin can result in losses greater than the amount initially deposited. Past performance is not necessarily a guide to future performance. The information in this article is for educational purposes only and does not constitute investment advice, a recommendation, or an offer to buy or sell any financial instrument. Consider whether CFD trading is appropriate for your circumstances and seek independent advice if necessary.
