I knew I was dealing with an amateur masquerading as an analyst. Apple is the largest company in the world, with a market capitalization of $412 billion. Exxon Mobil is second with a market capitalization of $391 billion and Walmart isn't even in the top 10 with a market capitalization of $244 billion. This is all VERY common knowledge in investment analyst circles...
Thanks for linking a wikipedia page on highest revenue companies, I got a good laugh out of you using it to justify your argument in claiming that I'm not correct.
Careful with those accusations.
Market cap measures VALUE. So the most
valuable public company in the world is the one with the highest market cap. Not the largest. If you knew the first thing about valuation you would know this.
An honest listing of company size NEVER uses market cap. It is usually revenue (sometimes number of employees, depending on what you are looking for).
Based on this information, why should we be unsurprised that the company with the highest market cap also has such a high margin?
Really, all you have done is proven that 20% margin is exceptional.
Just wanted to back this up with some data, so you don't make a bigger fool out of yourself by arguing over semantics.
I invite everyone to google "biggest company" and see what comes up.
