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 (-1,1%). The PC's and the monitors themselves are all from $HPQ (+1,22%) with keyboard and mouse from $LOGN (-0,16%). The telephone system is WebEx from $CSCO (-0,99%) and the work phones are from $AAPL (+0,52%) with $DTE (+0,03%) contract (and that although next door $VOD (+1,12%) sits). In addition, there are large monitors in each conference room from $DELL (-4%).
In the production of the semiconductors itself there are of course many machines from $ASML (-2,54%), $CAJ (-2,13%) and $7731 (-2,08%). The many industrial gases needed come from $LIN , $AI (-0,06%) and $4091 (-0,59%). The basic material and chemicals come among others also from $WCH (+0,81%) and $BAS (+0,28%).
The purchasers of the finished chips then include, for example. $VOW3 (-0,65%) , $BMW (-0,73%) , $MBG (-0,87%) and $TM (-0,69%). But also $V (-0,21%), $AAPL (+0,52%) and $SMSD (-2,68%) 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).
