I wrote Python code which shows Correlation between NASDAQ price, Corn and Gold(Corr=0.945). Corn and Gold are best mix I have found. https://gist.github.com/Kouhei-Takagi/a1a9b073f6cd6dacb7eb1ea871d8fd3c I changed some important parts. https://gist.github.com/Kouhei-Takagi/5becaf7c3a24d63ac9c56856e81297f2
2021/4/1. The 80:20 rule I wonder that how many times I have wrote this theme. 80:20 rule This is unfair rule which is called as “Pareto principle”. https://en.wikipedia.org/wiki/Pareto_principle If this rule is applied to whole people on the earth, what happens? Certain people(20%) can use 80% of the earth’s assets, and almost people(80%) can use 20% of them. The number of whole people on the earth is 7.9 billion. 20% of 7.9billion is about 1.6billion. How big is the 1.6 billion people? Almost as same as the number of Chinese. China vs USA is simple. Which is the king?
