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

Price is high, not quality! Oops, pride is too high...

EU Air Safety Body Urges Halt on Use of Kobe Steel Products

This is too problem! Japanese manufacturing quality is lower than past, and a lot of Japanese don’t realize it. They believe that Japanese manufacturing quality is too high and price is high. 
When I talked with one Chinese, we confirmed that Japanese manufacturing, only price is high. Unfortunately, this is not joke.

What by?
I think that cutting cost is surface problem, in deeper problem, Japanese companies’ system is too classic, and in more deep problems, there is the limits of mind & brain, which don’t accept new business & technology.
I mean that almost all Japanese can’t accept new (information) technology because they get old. People who is old easily deny new things.(Not all people!)
Denying new things is easy, but understanding new things is difficult.
And old people’s brain wants not to change their solid world.

In other words, Japan gets old...

Cheaper work

2016/12/29. Cheaper works: Hard competition makes expensive work cheaper. In Japan, there are some people who thinks there are a lot of workers, and they are exchangeable easily.

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!!!
