Would it be possible for a guy like Jeff to sell all his stock and convert his wealth to, let’s say, gold? The motivation for my question is my doubt that the different sources of wealth are comparable. So this ranking is hypothetical. Wouldn’t the stock price drop if someone was to sell so many shares?
I believe you are correct. In theory he would be able to turn all his assets into money, but probably he would loose huges amount of it in the process due to the effect you mentioned. I guess these rankings are just rankings. It's an abstract way to value what someone have (or could potentially have) with no relationship to absolute truth.
Is this error being used with intent? I have no interest in shaming grammar errors, it's just that I am seeing this too often here, in the same place where I read great arguments.
English is not my native language, so maybe this is a colloquial use of the word?
