“Cashing in” is on bets made many years ago is making my point. Amazon didn’t stop once it had the book market or even the online retail market (see AWS), Apple didn’t stop with ipod or iphone (see M processors/Airpods/Watch/etc), Meta didn’t stop with Facebook (see instagram/whatsapp/VR), Alphabet didn’t stop with Google (Waymo, Gmail, Drive), Eli Lilly with GLP-1 trials, etc.
They could stop, and switch to quarter to quarter decision making and juice their numbers even more. Maybe they will, and then eventually those businesses will drop in the rankings (IBM/GE/etc).
But the idea that quarterly reporting makes businesses short sighted is clearly false.
Leaders with short term motivations makes businesses short sighted (obviously). Sometimes, that’s justified because the business sector is winding down, sometimes it’s due to incompetence, and sometimes it’s due to greed.
You know I can easily give you plenty of counter examples of decisions made for short term gains and stock pumping, right?
At the end of the day most of these CEOs are valued by the stock price and they need to follow investors expectations which are very often short sighted.
Intel, Boeing and countless others are obvious examples.
All the companies you listed went the "let's cut personnel or bets even if we're making gazzilions to appease the stock market".
