Our selection of specific ETFs from the approximately 1,500 currently sold in Germany takes place in a multi-stage process that is repeated approximately every three months.
The most important quantitative and qualitative ETF selection criteria are as follows:
Low costs: Avoiding costs is one of the most important criteria for long-term investment success. When selecting ETFs, we pay particular attention to the total expense ratio (TER), which indicates the total costs of index replication, as well as the total cost of ownership (TCO), which takes into account external trading costs such as bid-ask spreads, taxes and broker commissions.
High Liquidity: ETFs with low trading liquidity typically have wider “bid-ask spreads,” which increases trading costs. We pay attention to ETFs with large investment volumes and multiple market makers to ensure the best possible tradability and minimize trading costs.
Adequate diversification: ETFs usually track very broad market indices, with dozens, often hundreds or thousands of individual stocks. This broad risk diversification enables access to the fundamental return drivers of the respective asset class without having to accept high individual risks. On the other hand, very broad indices contain a so-called long tail, i.e. a number of smaller companies with lower liquidity and therefore higher trading costs. Our selection process ensures a balanced and favorable relationship between risk diversification and implicit trading costs of the ETFs.
Secure replication method: ETFs are offered in two basic versions: with physical and synthetic replication of the underlying index. We only use physically replicating ETFs.
Other criteria we take into account are the closure risk associated with the fund size and on which low-cost exchanges the ETF is traded in euros.
It is not necessary to diversify across as many different ETF providers as possible, as the investor funds in ETFs represent “special assets”. A theoretically possible insolvency of the ETF provider would therefore be irrelevant to the investors' asset position.
