The title already says it.
To expand on this, I read about target date funds on this site. Essentially, they try to provide bigger gains with bigger risks at the start, and "automatically" become more conservative, the closer the target date comes.
As far as I know, in Germany, we have several funds with different risk strategies made specifically for retirement (e. g. from the DekaBank), but the shift towards more conservative strategies, I have to do on my own.
Isn't there such a product in Germany, and if not, why? Is it maybe due to regulations?
