FAQ - Invest

The average purchase price refers to the average price at which you invest in a financial instrument (funds for instance), over a given period.

When the market rises, the value of the units increases and you buy fewer units at a higher price. On the other hand, when the market falls, you buy more units at a lower price. You therefore buy securities at an average price without having to anticipate market trends in order to determine the best time to buy or sell.


You pay monthly instalments of 100 € into your investment funds. The number of units you buy with this amount varies each month as the markets fluctuate.
