>don’t know of anyone who uses their macro background to forecast specific asset prices (e.g., Amazon’s share price).

I can agree with that,

OTOH someone with uncanny ability to predict asset prices might be expected to do exceptionally well in macroeconomics, perhaps without any formal background at all.

A good deal of math would always be helpful and I like a mixture of business math and non-business math operating in the background.
