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 (+1,32%). The PC's and the monitors themselves are all from $HPQ (-0,63%) with keyboard and mouse from $LOGN (+1,24%). The telephone system is WebEx from $CSCO (+1,16%) and the work phones are from $AAPL (+0,28%) with $DTE (-2,85%) contract (and that although next door $VOD (+1,13%) sits). In addition, there are large monitors in each conference room from $DELL (+0,4%).
In the production of the semiconductors itself there are of course many machines from $ASML (-0,08%), $CAJ (+0,37%) and $7731 (-0,63%). The many industrial gases needed come from $LIN , $AI (+0,08%) and $4091 (-0,77%). The basic material and chemicals come among others also from $WCH (+2,7%) and $BAS (+1,27%).
The purchasers of the finished chips then include, for example. $VOW3 (+1,74%) , $BMW (+1,77%) , $MBG (+1,59%) and $TM (+1,22%). But also $V (-0,06%), $AAPL (+0,28%) and $SMSD (+0,14%) 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).
