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 (+0,86%). The PC's and the monitors themselves are all from $HPQ (-0,68%) with keyboard and mouse from $LOGN (-0,28%). The telephone system is WebEx from $CSCO (+2,06%) and the work phones are from $AAPL (+0,42%) with $DTE (+1,37%) contract (and that although next door $VOD (+0,59%) sits). In addition, there are large monitors in each conference room from $DELL (+0,75%).
In the production of the semiconductors itself there are of course many machines from $ASML (-0,65%), $CAJ (+0%) and $7731 (+0%). The many industrial gases needed come from $LIN , $AI (+1,33%) and $4091 (+1,71%). The basic material and chemicals come among others also from $WCH (+0,69%) and $BAS (+0%).
The purchasers of the finished chips then include, for example. $VOW3 (+0,1%) , $BMW (-0,01%) , $MBG (+0,53%) and $TM (-1,2%). But also $V (+0,92%), $AAPL (+0,42%) and $SMSD (-0,78%) 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).
