While it is anyone bet who is going to win the US election and how it will affect the stock price of Chinese companies, I think I would like to add more so long as it does not retrace back to the bearish trend line ( quite unlikely though possible)
To constantly want to catch the bottom price for fear of paying slightly more, imo is a short sighted move since share prices can be erratic in the short term.
I believe the forthcoming stimulus of 10-20 trillion by the Chinese government would help to propel the share price higher.
