As you can see, there are not many shares traded in the last weeks and months, so some people can bring down the stock prices by some 10 % with a trade of only 100 shares. And people are selling for any reason, as Peter Lynch says....
And have a look on the development of the stock price of a company, which is famous nowadays, like Microsoft or Apple. In their beginning it was a huge up and down in stock price until they were known to a huge investor community! And also they had huge news in their early days. But not so many people were following these companies or were doubtful about their future.
For KIWA, it is only a question of time, until stock price will explode in my opinion. Circumstances in China are extremely good for them and they already made huge progress in the past!
