"industries" is a misnomer

A firm, like $Microsoft (MSFT.US)$ , can be part of the Big Tech industry, but so are dozens of other companies. I get annoyed when someone says something like "invest in big tech" or "big tech is leading the charge".

I'd buy $Microsoft (MSFT.US)$ based on their route forward and current quarterly report, but wouldn't touch $Netflix (NFLX.US)$ (arguably a big tech firm) with a 10-foot pole because I see them near their saturation point and the media landscape changing in the relatively short term. I also see challenges for $Meta Platforms (META.US)$ and $Amazon (AMZN.US)$ while I think $Alphabet-A (GOOGL.US)$ still has room to run... despite all being in the same industry.
