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

Rethink: Japan as No.1 technology?

I rethink that Japan has No.1 fields of science & technology or not.
By wikipedia, (https://en.wikipedia.org/wiki/Science_and_technology_in_Japan)
Japan has 4 good fields, aeronautics, nuclear power, electronics, biomedical research.

1)Aeronautics
Is this real? I don't feel that Japan has original technology. And if Japan has original technology, I wonder how to make money from it. Is aeronautics field big or small/Japanese economic GDP?
And catching up by China is hard...

2)Nuclear power
This is... too bad. The new construction of nuclear power plant will be decreased...

3)Electronics
I can't think that this field by Japanese companies becomes to be bigger than now. Because basic OSs are Windows, iOS, Linux... There is Japanese OS Tron (Not movie title!). But no power to be consumer OS.
So if Japanese electronics will survive (not = revival) in future, companies will escape to B to B business.

4)Biomedical research
This! This will be cash cow! (I hope) Especially, iPS cell will be big business. The problem is licence & business... These are locked by big brand company. Individual investors can't get profits from it.

I think that Japan doesn't have No.1 science & technology as some people said or thought.
As a investor, Japan may be losing the attraction... And this may be why many Japanese become more conservative.

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. This thought can't stand on human populations decreasing society. And in this society, the flow that provides products cheaper and cheaper cannot keep. Now, Japanese society is standing on that thought, and Japanese system hardly stands. This is by the patience of Japanese. When the breaking point of Japanese system comes, the counter of patience will keeps long time. And I think that communism never comes in Japan. Because Karl Marx doesn't think about human populations decreasing...

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!!!
