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 (-0,2%). The PC's and the monitors themselves are all from $HPQ (+0%) with keyboard and mouse from $LOGN (+1,41%). The telephone system is WebEx from $CSCO (-0,48%) and the work phones are from $AAPL (-0,02%) with $DTE (+1,04%) contract (and that although next door $VOD (-0,92%) sits). In addition, there are large monitors in each conference room from $DELL (-2,07%).
In the production of the semiconductors itself there are of course many machines from $ASML (-0,48%), $CAJ (+0%) and $7731 (+1,74%). The many industrial gases needed come from $LIN , $AI (+0,77%) and $4091 (+0,62%). The basic material and chemicals come among others also from $WCH (+1,66%) and $BAS (+2,39%).
The purchasers of the finished chips then include, for example. $VOW3 (+2,74%) , $BMW (+4,25%) , $MBG (+3,32%) and $TM (+2,72%). But also $V (+0,62%), $AAPL (-0,02%) and $SMSD (-0,5%) 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).
