Maybe the big players have come to recognise that the RPE (risk to potential earning) ratio is just too high. I will bow to michaelhp's higher experience in the stock that its liquidity is insufficient to withstand a determined sell-off without a significant price impact but until we get a SSH notice that is still conjecture.
At present the RSI continues to decline. My view is that uncertainty over future earnings combined with high PE is driving the market at present.
