It took 100+ years to get here:
23 months and one global pandemic later:
AAPL $1.65T
MSFT $1.61T
AMZN $1.54T
How's that work?
A glance at Apple:
FY2015 net income was $53.39B
TTM net income was $57.22B
12.31.2015 share price was: $105.26
Current share price is: $373.85
Annual net income is up 7% in total over the last 5 years.
Share price is up 251% over the same period.
Hhahahha. I knew you would chime in. I almost put a where's @S2007S in the first post.The way they are trading they will have 3 trillion dollar market caps by 2021. 3 companies making up half the US gdp. Yep something is very very very wrong, but as they say this time its different. Right?

I disagree with that. Yes its easier now for the Dow to go up 1000 points than it was in say the year 2000, its all a percentage thing like you say.... the actual number is arbitrary... but these are real companies and we are talking real dollars. Has our GDP went up 50% in the last two years? Has the world's? There's only so much money out there. Last I looked, John and Suzie Q. Consumer haven't seen their paychecks jump 50% in the last 2 years, and where the rubber meets the road... a business is a business is a business.It works very well in my opinion!
The same phenomenon has always and most likely will always be true, just the decimals change. We'll get to a 2 quadrillion market cap a LOT faster than it will take to get to 1Q.
