There is no "trader" in China. If someone prints the word "trader" on a business card, it will be a joke in our industry.
Don't be too superstitious about traders. This market has such a large capacity that one person and one fund can't affect the index fluctuation of one day.
Add a love poem by Cangyang Jiacuo-you buy, or don't buy, buy more and buy less, the index is there, follow the curve it should follow, and it is out of your control.
