The last 10 years were unlike any other. Total global debt increased by 11% compound rate vs real GDP growth of 4%. Credit growth has outstripped real GDP growth by 275%.
Peter Bernholz noted 28 episodes of hyperinflation in 20th century, with 20 occurring after 80s. He found a pattern that a tipping point of hyperinflation occurred after government's deficits reached 40% of its expenditures. The US is past this point. Banks are holding massive excess reserves, which if they decided to deploy or lend out, could increase the money supply by 6 TRILLION, triggering massive inflation.
Ken Rogoff along with Carmen Reinhart studied sovereign defaults and put a tipping point of defaults at approximately 4.2x debt/revenue. The US is coming dangerously close. At 16x debt/revenue, Japan may blow up sooner than we all think.
With massive tectonic shifts happening in the global economy, consider the performance of traditional value investors versus macro investors. All the winners you can think of off the top of your head - Paulson 07, Burry ('05-'09), Kyle Bass - have been macro guys. Value investors Berkowitz, Paulson '11, Ackman, etc have not done very well at all (first two are down >30% this year).
Has value investing become impractical in todays day and age?
FWIW, I have been spending an inordinate amount of time on the macro, but have yet to switch my investing style away from cigar butt value to macro.
