What is the AEX Index?
The AEX Index is a key benchmark for the Dutch stock market, comprising the 25 largest and most actively traded companies listed on Euronext Amsterdam.
It provides investors with a comprehensive overview of the performance of the Dutch economy, serving as an important indicator of market trends and investor sentiment.
The AEX Index was established in 1983 with a base level of 100 index points, making it one of Europe's leading indices, reflecting the growth and development of the Dutch economy over time.
This index is weighted by free-float market capitalization, meaning that larger companies have a greater impact on its performance.
Larger companies like Royal Dutch Shell can have a more substantial effect on the overall index compared to smaller companies.
The AEX Index serves as a representation of the broader Dutch stock market, including both domestic companies and multinational corporations with a significant presence in the Netherlands.
This diversity allows investors to gauge not only the performance of local businesses but also the impact of global economic factors on the Dutch economy.
Composition and Calculation
The AEX index is composed of the 30 largest companies listed on the Amsterdam Stock Exchange in the Netherlands. These companies are selected based on their market capitalization, with the largest companies having the greatest weight in the index.
The AEX index is a capitalization-weighted index, meaning that the weight of each company is determined by its market capitalization. At each main annual review, the index weightings of companies in the index are capped at 15%, but range freely with share price subsequently.
The index is calculated using a formula that takes into account the number of shares, free float factor, capping factor, and price of each company. The formula is:
It=∑ ∑ i=1NQi,tFi,tfi,tCi,tdt
Where:
- It is the value of the index at any given time
- N is the number of constituent shares in the index (usually 30)
- Qi,t is the number of shares of company i on day t
- Fi,t is the free float factor of share i
- fi,t is the capping factor of share i (exactly 1 for all companies not subject to the 15% cap)
- Ci,t is the price of share i on day t
- dt is the index divisor (a factor calculated from the base capitalization of the index)
Here is a list of the current constituents of the AEX index, along with their index weighting:
Trading and Investing
AEX stock trading offers investors a popular investment option to diversify their portfolios and potentially earn significant returns. By trading stocks within the AEX, investors can gain exposure to a diverse range of industries and potentially benefit from the performance of these leading Dutch companies.
The AEX is one of Europe's most liquid stock exchanges, with high trading volumes and tight bid-ask spreads, ensuring that investors can easily buy or sell shares without significantly impacting the stock's price. This liquidity is a significant advantage for investors.

Buying Options
To buy options, you'll need to find the AEX options under 'Realtime AEX-koers vandaag en AEX-nieuws' on the Euronext website. This is where you can see the AEX options with different expiration dates. By clicking on the option with the desired expiration date, you'll see the option matrix with current price information.
The AEX options are available for both call and put options. Call options give you the right to buy the AEX index at a specific price (strike price) before the expiration date, while put options grant you the right to sell the index at the strike price.
You can choose between these two types of options based on your market outlook and desired strategy. For example, if you believe the AEX index will increase in value, you could buy call options at a strike price slightly below the current index level.
The prices of AEX options are influenced by several factors, including the current level of the AEX index, time until expiration, volatility in the market, and interest rates. Understanding these factors is crucial for making informed trading decisions.
