THREAD AWS $AMZN
AMZN has 15Xed in 6 years (~$60bn->~$1tr). Along the way there have been many investor concerns, which have in hindsight been "can't see the forest for the trees" nitpicks: 1) AWS not profitable; 2) AWS price cuts; 3) Depr acctg; 4) Too much start up exposure.


Looking back on it, it is funny to think about a few of the past AWS bear cases/worries:
AMZN first disclosed AWS financials on the 1Q15 print. Before AMZN disclosed AWS revs/EBIT, the consensus was the MORE unprofitable AWS was, the better it was for AMZN’s stock because it meant the retail business was even more profitable than people thought.

After AMZN disclosed the AWS metrics, valuation hawks jumped all over the AWS disclosures. 50% adj. EBITDA margin were masked by 1) capital leases and 2) depreciation shenanigans.
I remember the 2015/16 tech downturn vividly. I was on the sell side covering smidcap internet. Almost half of my smidcap Internet names down 40+% earnings in November 2015.

Krugman is, of course, right about this. BUT, note that universities can do a lot to revitalize declining and rural regions.

Viruses and other pathogens are often studied as stand-alone entities, despite that, in nature, they mostly live in multispecies associations called biofilms—both externally and within the host.
https://t.co/FBfXhUrH5d
Microorganisms in biofilms are enclosed by an extracellular matrix that confers protection and improves survival. Previous studies have shown that viruses can secondarily colonize preexisting biofilms, and viral biofilms have also been described.
...we raise the perspective that CoVs can persistently infect bats due to their association with biofilm structures. This phenomenon potentially provides an optimal environment for nonpathogenic & well-adapted viruses to interact with the host, as well as for viral recombination.
Biofilms can also enhance virion viability in extracellular environments, such as on fomites and in aquatic sediments, allowing viral persistence and dissemination.
