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 (+0,1%). The PC's and the monitors themselves are all from $HPQ (+0,51%) with keyboard and mouse from $LOGN (-0,17%). The telephone system is WebEx from $CSCO (+0,19%) and the work phones are from $AAPL (-0,34%) with $DTE (+0,55%) contract (and that although next door $VOD (+1,89%) sits). In addition, there are large monitors in each conference room from $DELL (-0,03%).
In the production of the semiconductors itself there are of course many machines from $ASML (-0,6%), $CAJ (-2,04%) and $7731 (-0,68%). The many industrial gases needed come from $LIN , $AI (+0,03%) and $4091 (-0,25%). The basic material and chemicals come among others also from $WCH (-0,48%) and $BAS (-0,54%).
The purchasers of the finished chips then include, for example. $VOW3 (-1,33%) , $BMW (-1,44%) , $MBG (-1,54%) and $TM (-1,36%). But also $V (+0,15%), $AAPL (-0,34%) and $SMSD (-0,06%) 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).
