I got this question just now. The guy signed out so cannot reply
Can you tell me an absolute objective way to measure risk does exist?"
If you measure risk to wealth there is no such benchmark because there are no assets which rise or fall at the same pace as is needed. OR even close to that.
Not only can you not measure the risk but you cannot insure against it by investing in the kind of assets which provide such protection. There are none.
Until this changes the economies of this world will be unsafe and unstable.
