The AEX index is a weighted average of the most important 25 companies whose shares are traded on the Amsterdam Stock Exchange. It is now interesting to see how the price of the different funds develop in relation to each other, over a period of 12 months. We can achieve this by indexing the price of each fund to ‘1’. So on day 1 the value of each fund is 1 euro. Then you can see the actual price development in the graph above. Now you can immediately see which funds are outperforming the AEX and which funds are lagging behind.
