Companies traded on the stock exchange in everyday professional life
Since I am @Simpson nominated, I now grant an insight into listed companies in my daily professional life.
Briefly about me: I am a mathematician and work in the semiconductor industry in a listed company.
Starting with the software: pretty much all computers in the office run Windows and Office from $MSFT (-0,11%). The PC's and the monitors themselves are all from $HPQ (+0,19%) with keyboard and mouse from $LOGN (+0,58%). The telephone system is WebEx from $CSCO (-0,66%) and the work phones are from $AAPL (-0,43%) with $DTE (-0,15%) contract (and that although next door $VOD (-0,08%) sits). In addition, there are large monitors in each conference room from $DELL (-0,18%).
In the production of the semiconductors itself there are of course many machines from $ASML (+2,61%), $CAJ (-2,94%) and $7731 (-2,85%). The many industrial gases needed come from $LIN , $AI (+2,64%) and $4091 (-1,11%). The basic material and chemicals come among others also from $WCH (-1,2%) and $BAS (-0,54%).
The purchasers of the finished chips then include, for example. $VOW3 (-1,21%) , $BMW (-0,89%) , $MBG (-0,46%) and $TM (-3,25%). But also $V (-0,61%), $AAPL (-0,43%) and $SMSD (+1,27%) are customers.
I have certainly forgotten a lot, but as an insight it should be enough I think.
I nominate @DonkeyInvestor , @GoDividend and @Divmann (sorry if someone has already been nominated, I don't have an overview anymore).
