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 (-2,18%). The PC's and the monitors themselves are all from $HPQ (+1,96%) with keyboard and mouse from $LOGN (+1,39%). The telephone system is WebEx from $CSCO (+2,79%) and the work phones are from $AAPL (+1,44%) with $DTE (+2,17%) contract (and that although next door $VOD (+1,78%) sits). In addition, there are large monitors in each conference room from $DELL (+5,36%).
In the production of the semiconductors itself there are of course many machines from $ASML (+1,94%), $CAJ (+0%) and $7731 (+0,75%). The many industrial gases needed come from $LIN , $AI (+1,9%) and $4091 (-2,42%). The basic material and chemicals come among others also from $WCH (+3,63%) and $BAS (+3,38%).
The purchasers of the finished chips then include, for example. $VOW3 (-0,69%) , $BMW (-0,77%) , $MBG (-1,15%) and $TM (+0%). But also $V (-0,08%), $AAPL (+1,44%) and $SMSD (-2,36%) 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).
