Wouldn't it be surprising if SINO made gains now and held them? It could be the start of a new trading pattern however in the not-so-distant past we had significant positive news, earnings, your S/A article, all of which resulted only in temporary price gains. Maybe something is happening in the background that isn't public knowledge or perhaps a fund is starting a position. If past precedence holds I'd expect it to be trading back below $3 next week.
There's a fair amount of exuberance on the board here which I can understand being excited but I feel like some caution is warranted since nothing fundamental has changed from last week.
