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 (-0.12%). The PC's and the monitors themselves are all from $HPQ (+0.23%) with keyboard and mouse from $LOGN (-0.47%). The telephone system is WebEx from $CSCO (-0.19%) and the work phones are from $AAPL (+0.16%) with $DTE (-0.29%) contract (and that although next door $VOD (-1.15%) sits). In addition, there are large monitors in each conference room from $DELL (-3.23%).
In the production of the semiconductors itself there are of course many machines from $ASML (-1.52%), $CAJ (+0%) and $7731 (-1.89%). The many industrial gases needed come from $LIN , $AI (-1.04%) and $4091 (-1.11%). The basic material and chemicals come among others also from $WCH (-0.34%) and $BAS (-1.27%).
The purchasers of the finished chips then include, for example. $VOW3 (-0.84%) , $BMW (-0.09%) , $MBG (-0.32%) and $TM (-1.76%). But also $V (+0.31%), $AAPL (+0.16%) and $SMSD (-0.52%) 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).
