If inflation continues hot don’t stock prices eventually have to go up though? If Apple raises the price of iPhones 50% because its input costs went up 50% and (assuming sales remain the same, I’m only talking inflation, not a depression), then they’re making $9/share instead of $6/share so unless people think Apple at a 15 PE is overvalued its share price would go up.
