The culprits here are big players who have sofisticated software and making their fortunes by spreading fear.
By shaking the tree and taking shares from the weak hands.
If retail holders would stop selling their shares on the way down this game would not work any more.
But it works everytime because the weak keep handing over their shares hoping to buy them back cheaper.
Simple as That and it happens to many Shares on the ASX sometimes clearly visible and otherwise only visible to the trained eye.
