big sell after the bell

Yes folks, at ten past four the high rollers moved in with a big sell at 1.5¢ : 1,000 shares... That's right, one thousand. That's $15 worth by my calculation...

Why on earth would anyone in their right mind sell $15 worth of stock in anything??? Did they buy them at 0.1¢ and decide to take profits?

The mind boggles - or did someone just want to see the share price lower (the stock would have finished the day flat at 1.6¢ instead of showing -6.25%).
