A bit profit taking by those who don't see the bigger picture and are happy with a small gain. That gives others the opportunity to get in at a still very low price.
Once it reaches 10c then I would say it is time to check sales figures to decide if it's a buy or not. But until then it is close to a no-brainer.
But we've said that at 3.2c already and no one believed us. Maybe they do now.
