It depends on your position size and time frame. It is troubling to see SFUN fell below 50 day sma in larger volume today, but then many other Chinese names like VIPS, SOHU and WUBA had been retreating as well. SFUN gained like 40% from its February bottom to peak of $99.75, and so it is no ususual to see this level of pullback in a such a short time as well. Today, SFUN even fell below its 100 sma. I would use any bounce to unload unless I see volume coming back in in its rebound.
