Here's an interesting one. Goes back to the @Sector volume play type situations we use to discuss quite a bit a while ago.

RHT announced FDA approval this morning and have been up 100+ %

Lets backtrack a little until Oct 22... big volume and a please explain by the ASX. 

'Nothing to see here' ... or something like that. I seen this on a scan and didn't bother to look into it, nor keep an eye on it. Have been a bit lazy in this market.

You never do know the reasons for large volume, but there's definitely a few out there that are worth paying attention to if you know a little more about the stock and the story.
