What Is GER40 in CFD Trading? The Germany 40 Index Explained

GER40 is one of several trading symbols brokers may use for a CFD that tracks Germany’s DAX index. Other common names include DE40, DAX40 and Germany 40, depending on the broker or trading platform.

The underlying DAX tracks 40 major companies listed on the Frankfurt Stock Exchange. Understanding how the index and its CFDs work can help traders assess price movements, trading costs and the risks involved in taking leveraged exposure to the German equity market.

This guide explains what GER40 is, how DAX-based CFDs work, their main costs and the economic factors that can influence the index.

What Is GER40 in CFD Trading?

GER40 commonly refers to a Contract for Difference (CFD) based on Germany’s DAX index. It allows traders to speculate on movements in the index without buying shares in each of its constituent companies.

GER40 is not a universal exchange ticker. Brokers may instead use names such as DE40, DAX40 or Germany 40 for products linked to the same underlying German benchmark.

The DAX tracks 40 major companies listed on the Frankfurt Stock Exchange and is weighted according to free-float market capitalisation. Its constituents include companies from sectors such as technology, financial services, industrials and consumer goods.

In the context of CFD trading, an index CFD provides exposure to the movement of a broad equity benchmark through a single position. You can go long if you expect the price to rise, or short if you expect it to fall.

When a GER40 CFD position is closed, the gain or loss is based on the difference between the opening and closing prices, adjusted for the size of the position and any applicable trading costs.

How GER40 Works: Index Structure and Trading Mechanics

The DAX underwent a major change in September 2021, when Deutsche Börse expanded the benchmark from 30 to 40 constituents.

Deutsche Börse designed the reform to broaden the index and add new eligibility requirements. DAX constituents are primarily weighted according to their free-float market capitalisation, while individual company weights are capped at 15%. Major constituents include companies such as SAP, Siemens, Allianz and Airbus.

An important feature of the DAX is that it is usually quoted as a performance index. This means dividends paid by constituent companies are mathematically reinvested in the index calculation.

Deutsche Börse also calculates price and net-return versions of the DAX, so the familiar headline DAX is more accurately described as the performance-index version — not a total-return index.

This distinction matters when comparing the DAX with price-return indices such as the Dow Jones Industrial Average, commonly referred to as US30 on CFD trading platforms.

Xetra’s regular trading session runs from 09:00 to 17:30 Central European Time. CFD providers may offer GER40 trading outside these hours, but the exact trading schedule and pricing methodology depend on the broker.

Costs and Leverage on GER40 CFD Positions

Trading GER40 CFDs can involve several costs. These may include the spread, overnight financing and, depending on the account or provider, commissions or other charges.

When comparing trading costs, traders should therefore look beyond the advertised spread and consider the total cost of opening and maintaining a position.

For UK retail clients, Financial Conduct Authority (FCA) rules limit leverage according to the underlying asset. CFDs on major stock indices can be offered with leverage of up to 20:1. This corresponds to a minimum initial margin requirement of 5%.

GER40 Margin and Risk Example

This simplified example shows how leverage increases the effect of relatively small market movements on the capital committed as margin. A 1% adverse move in the underlying index would represent a 20% loss relative to the €900 initial margin in this example, before trading costs.

The FCA requires CFD providers to disclose the proportion of their own retail client accounts that lose money. The regulator has also previously reported that approximately 80% of customers lose money when investing in CFDs. The exact percentage displayed in a broker’s risk warning can differ because firms must calculate and update their own figures.

Overnight financing may apply when a cash CFD position remains open beyond a provider’s daily financing cut-off. The rate, calculation method and cut-off time vary between brokers, so traders should check the provider’s contract specifications before opening a position.

Spreads can also change according to liquidity, volatility and the provider’s pricing model.

What Moves the GER40 Market?

GER40 prices can respond to German and Eurozone economic data, monetary policy, global market sentiment and company-specific developments.

Important factors include:

• European Central Bank policy: Changes in interest rates and ECB guidance can affect borrowing costs, economic expectations and equity valuations.
• Economic data: German and Eurozone inflation, GDP, industrial production and sentiment indicators can influence expectations for the economy and monetary policy.
• Currency movements: Many DAX companies generate revenue internationally. Changes in the euro can therefore affect the translated value of overseas earnings and the competitiveness of exporters, although the impact varies between companies.
• Corporate earnings: Results and guidance from heavily weighted constituents can influence the wider index.
• Global market conditions: Developments in US and Asian equity markets, geopolitical events and changes in global risk sentiment can also affect the DAX.

What Are the Risks of Trading GER40 CFDs?

GER40 CFDs are leveraged products, so relatively small price movements can produce much larger gains or losses relative to the margin used to open a position.

Market gaps and slippage are two important execution risks. If the market moves rapidly through a stop-loss level, an order may be filled at a different price from the one requested.

The opening of the European cash session can also bring increased trading activity as new information is incorporated into prices. Short-term volatility and execution conditions may change around the Xetra open, so traders should not assume that spreads or available liquidity will remain constant.

The exact level of slippage depends on factors including market conditions, order size, order type and the broker’s execution model. There is therefore no reliable basis for claiming that waiting exactly 15 minutes after the Xetra open will consistently provide better execution.

Holding a cash CFD for several days may also result in repeated overnight financing charges. These costs can become significant over time, particularly when the expected price movement is relatively small.

What Is GER40? Summary and Trading Considerations

GER40 is a common broker name for a CFD linked to Germany’s DAX index. It gives traders a way to take leveraged long or short positions on movements in a major German equity benchmark without owning the underlying shares.

The DAX contains 40 major German-listed companies and is commonly quoted as a performance index that assumes dividends are reinvested. However, the specifications of GER40 CFDs — including spreads, contract sizes, trading hours and overnight financing — can differ between providers.

Leverage also increases risk. Position sizing, margin requirements, execution conditions and total trading costs should therefore be considered before opening a GER40 CFD position.
