You have an opinion against data.
And when your data runs contrary to Amazon, Apple, Facebook, and tons of other points of data in today's market... I think its reasonable to question the data. Is data from 1870s still relevant today? The USA was still on gold + silver (silver standard!!), and the Fed didn't even exist yet.
Case in point: maybe your data is only relevant during the times when the gold standard was still being followed (before the 70s, when Nixon finally ended the gold standard).
The economy of today's market is grossly different than 1600s era Dutch traders.
Are those companies bad? Probably no. Will they plunge and be available at a steep discount? Quite likely.
They even had options, called "opsies".
