I agree 100%.
It has acted this way since 2008, and won't change until the next business cycle occurs 2018-19
The only way I've ever made any money on this was buying puts after each run up and stagnation
Right now, China is the U.S. in the 1950s, huge middle class growth.
Best to put money there for now in growing companies that trade on the U.S. exchanges, like BABA, MOMO, etc...
This once great country is falling apart
