My guess (it only just that) is that this is a stock that traders (short-sellers, algorithm traders/robot traders) are currently playing: it is their playground. All it take is a serious investment company to jump on board to take the play out of these traders. Perhaps this is already happening: who knows? Had seen the volume of bid at 33.5c keeps coming in. Perhaps this is the entry price that this investment company is willing to take or it could just be short sellers covering their shorts. I have no idea!! Below are the volume of shorts.
