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 (+0,93%). The PC's and the monitors themselves are all from $HPQ (+1,94%) with keyboard and mouse from $LOGN (+1,46%). The telephone system is WebEx from $CSCO (+2,56%) and the work phones are from $AAPL (+2,14%) with $DTE (-0,24%) contract (and that although next door $VOD (+1,05%) sits). In addition, there are large monitors in each conference room from $DELL (+3,07%).
In the production of the semiconductors itself there are of course many machines from $ASML (+1,26%), $CAJ (+0%) and $7731 (-0,86%). The many industrial gases needed come from $LIN , $AI (-0,05%) and $4091 (-1,27%). The basic material and chemicals come among others also from $WCH (-0,24%) and $BAS (-0,19%).
The purchasers of the finished chips then include, for example. $VOW3 (-0,74%) , $BMW (+0,29%) , $MBG (-0,26%) and $TM (+0,62%). But also $V (+1,56%), $AAPL (+2,14%) and $SMSD (+0,77%) 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).
