You can think of a fund as a kind of financial stew: Many investment options (stocks, bonds, real estate, etc.) are usually managed by a fund manager (active) or by an algorithm (passive). 

The fund manager buys or sells individual securities for the fund. The sum of all securities form the so-called fund assets, which in turn are divided into fund shares. When you buy fund shares, the price of a share is calculated by dividing the sum of the fund assets by the number of shares. 

Funds can either contain only one type of security (for example, pure stock funds) or have mixed securities such as stocks and bonds. These are then called mixed funds. We chose an equity fund, which is an impact fund. An equity fund offers the opportunity to invest for the long term: With a strategy that is not focused on daily fluctuations and profits, but in the best case permanently focused on the goals of your financial future. Of course, there is also a risk up to total loss involved - you can read more about investment risks here.
