Saying last decade’s bull run happened because of the FED is insane

I often see around here everyone claiming that the last decade's bull run is solely because of the loose monetary policy Fed has adapted after the 2008 crisis, and the QE is the only reason we are at the current levels, the market has been propped by the Fed etc. And we are going to see it all go away when Fed starts QT.

I believe as a foreigner, Americans here are underestimating how influential and huge the American companies have become over the last decade. They have basically dominated the globe and the bull run that started after the 2008 crisis is due to their success.

I don't think you can find a place on developed world where someone never heard of an iPhone, or an office that never used Excel, or an Adobe product, or doesn't have an Instagram, or doesn't check Amazon to buy something etc. There are many more examples. And no, this was not the norm before the last 10-15 years, not this much.

Lets look at the revenue growth of some huge global companies in Nasdaq index.

Amazon: 2009 – 24 billion, 2022 – 469 billion
Apple: 2009 – 42 billion, 2022 – 365 billion
Google: 2009 – 23 billion, 2022 – 257 billion
Microsoft: 2009 – 58 billion, 2022 – 168 billion
Meta: 2009 – 0.7 billion, 2022 – 117 billion

So when a company increases their global revenue up to 10, 20, 30 times what do you think will happen to its stock? How is their huge global success all over the world is just because of Fed's QE? Are people in Europe using Instagram on their iPhone's they bought from Amazon because of the Fed?

American companies had an incredibly successful decade and the bull run is perfectly in line with this. And the Nasdaq PE is at 21 right now, not 100.
