Think you need to understand trading a lot more to understand what a real dump of stock is, today is just traders selling out of positions with a low volume day again, and at the end there was no dump there were reasonable parcels being snapped up and bought up not sold down, including the 500k shares bought in auction and that parcel at 1.8 with the one seller is just another trader getting out as many took decent positions last week and earlier in the week thinking the ascending triangle, symmetrical triangle formations were ready to break.
Chart shows the selling has been out of the blue and dramatic but also on low volume and has become oversold, market is now cautious until it finds it's feet again. We've seen before on MOX how easy it goes up, with buyers line wiping out of nowhere and that will likely happen again when the timing is right.
