In the UK we have a convenient way of observing this phenomenon.
The FTSE100 is mostly multinational companies valued in pounds. The FTSE250 is mostly British companies valued in pounds. If the FTSE100 goes up while the FTSE250 stays flat or falls then it means the currency got devalued and there's no real growth.
It's kinda like saying during "My bread appreciated!" during hyper inflation.
IMO we're in one of the cases where "Number go up" is actually bad.
