Correlation between NASDAQ price, Corn and Gold(Corr=0.945)

 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

Cheaper economy in Japan

 2021/7/16.  Cheaper economy in Japan 


I ate alone dinner at Yayoiken in Japan.

Hummm. It costed ¥780, approximately US$7.10.

Is this too cheap?

I ate at Tokyo Ginza in Japan.


I don’t want to tell how good taste it was or how beautiful the dinner was.(And it was not so beautiful, just only one meal.)

What makes it so cheap?


Law of one price seems to have strong power in Japan.

I think that law of one price prevents raising price in Japan.

I want to think more deeper about this topic, later.

None feedback

2016/12/29. None feedback from others in Japanese company Feedback is not always visible or sound , especially the fact of feedback is hidden by various suits. And in Japanese company, I often see the scene that ignorance to the people who did careless mistakes. Others don't say anything about the careless mistakes in front of the person, but in background, others speak ill of the person. This is none feedback. None feedback from others is very bad feedback, but in Japanese company, it is often. Why none feedback happens? In my experience, there are some reasons. When the person who made mistakes is upper than others, others want the person to fall out. When the person is equal level to others, others want the person not to promote. When the person is lower level, others want to make the person the targets for inner circle. I rethink that none feedback in company is bad signal for organization... None feedback happens when the company is bad statements!!!
