IMHO the main selling pressure is nothing more than fear of the past.
Daytraders who missed getting a full position at a good price BEFORE the Huajie deal was announced are very well versed in market psychology. They know all too well that all they have to do is just mention a few keywords like "Toups", "RTO", "RedChip", and "scam" along with a reminder that many china stocks have been reduced to short trading vehicles to be sold off on any news.
In other words, the daytraders are just the messenger suggesting that investors focus on fear of how RTO stock charts have traded in the past. So the problem lies in two areas - First, overcoming the stigma painted across the entire sector, and second, investors learning to grow a spine and ignore the ramblings of daytraders whose mission is to create volatility all the time - pumping the news, selling the pop, then bashing relentlessly so they can create the next low entry point as quickly as possible to wash, rinse, and repeat.
