As many readers know, I have been working in Swiss private banking for most of my career and I have witnessed first-hand the sales practices of these companies. By now, every Swiss bank pretends to have an open architecture where they offer both in-house and third-party funds, but in practice, the incentives in all these banks are skewed towards pushing in-house products. But I am not complaining, private banks are in the business of making money and in-house products simply are more profitable, so they are promoted more than less profitable third-party products.
The remedy I have followed is: Do not buy from a Bank. Do your own research and decide which Fund is best for your context,
