Why GDP isn't the best predictor of EPS growth:
"The biggest reason for this non-intuitive result is that the relationship between GDP growth and
earnings per share (EPS) growth that most people assume must be there does not exist in the long
run. The two developed countries with the strongest EPS growth between 1980 and 2010 were Sweden
and Switzerland, which each had lower than average GDP growth. Canada and Australia, which saw
the strongest GDP growth, showed very little aggregate EPS growth. Why? A big reason is dilution.
Canada and Australia saw strong growth from their commodity producing sectors, but that growth
came from massive investment, which was funded by diluting shareholders. Switzerland and Sweden
did not invest as much and did not dilute their shareholders, leaving shareholders better off despite
lower economic growth."
It's the GDP growth surprise which has stock market impact:
"If you can find cheap countries that are going to have a big positive GDP surprise over the next three
years, you’ll outperform by a whopping 14.1% per year for the next three years, whereas if you are
unlucky enough to buy the cheap countries that will have the worst GDP surprise, the outperformance
is only 0.7%. Our strongest takeaway at GMO is that even the cheap countries with the worst GDP
surprise still outperform, and even the expensive countries with the best GDP surprise still lose. The
macroeconomic performance matters, but given how hard it is to predict who is going to do better
than expected and the fact that it doesn’t change the sign for either the cheap or expensive countries,
we’re sticking with value."
