I can't figure this out either. On last Friday, for example, the last few trades late in the day dropped the price drastically but then after the close a major trade brought it back up to even for the day. According to multiple web pages I have read there is no after hours trading for pinksheet stocks. This seems to have started happening soon after HHSE hired a market maker. I wonder if that doesn't have something to do with it since they have the ability to do things normal investors don't? Today's after hours trade was the biggest of the day at 528,000 shares and dropped the pps down by about 13% from the official close up of 5.84%.
