reasons for obj sp movement today

So what do we all think was the reason for the movement today? The open higher at 5.8 cents then went a little higher to 5.9 then down to mid 5s before it dropped to the days low at 5.0 and bounced up again. What do we think is going on here? Traders dumping and then rebuying once it hit 5 cents? How did they know it would be dumped by everyone else at high 5s? Insiders selling their shares with unfavourable news on the horizon?
