Where do the percentages come from? I wouldn't invest in Nestle, for example. You can't exactly report positive things about the others either. Personally, I don't have any in my portfolio.
@Verbraucherengel If you really look for it, you will find something to criticize about every company. Nestle and others are probably so in the spotlight that they can hardly afford to make mistakes. Others, under the radar, continue unabashedly.
