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 (+3,58%). The PC's and the monitors themselves are all from $HPQ (+1,37%) with keyboard and mouse from $LOGN (-3,21%). The telephone system is WebEx from $CSCO (+0,59%) and the work phones are from $AAPL (-0,53%) with $DTE (-1,41%) contract (and that although next door $VOD (-2%) sits). In addition, there are large monitors in each conference room from $DELL (+4,48%).
In the production of the semiconductors itself there are of course many machines from $ASML (+2,11%), $CAJ (-0,66%) and $7731 (-0,71%). The many industrial gases needed come from $LIN , $AI (+0,88%) and $4091 (+0,64%). The basic material and chemicals come among others also from $WCH (-1,9%) and $BAS (-0,77%).
The purchasers of the finished chips then include, for example. $VOW3 (-0,3%) , $BMW (+0,72%) , $MBG (+0,17%) and $TM (+0%). But also $V (-0,13%), $AAPL (-0,53%) and $SMSD (+1,22%) 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).
