# The investment universe consists of 32 countries with easily accessible equity markets (via ETFs, for example). At the end of every year, 
# the investor calculates Shiller’s “CAPE” Cyclically Adjusted PE) ratio, for each country in his investment universe. CAPE is the ratio of 
# the real price of the equity market (adjusted for inflation) to the 10-year average of the country’s equity index (again adjusted for inflation). 
# The whole methodology is explained well on Shiller’s home page (http://www.econ.yale.edu/~shiller/data.htm) or
# http://turnkeyanalyst.com/2011/10/the-shiller-pe-ratio/). The investor then invests in the cheapest 33% of countries from his sample if those 
# countries have a CAPE below 15. The portfolio is equally weighted (the investor holds 0% cash instead of countries with a CAPE higher than 15)
# and rebalanced yearly.
