Sorry if we missed your question RE director selling.
There are prescribed times directors can sell stock and when they cannot. There is a blackout between the end of a reporting period such as June 30 and the release of results when directors cannot trade – this is fairly straight forward, however there are other times when it is more grey, and valid arguments could be made where directors are trading on information that is not available to the public. That in itself is illegal as directors have obligations around continuous disclosure, i.e. they must inform the market of any ‘material’ information around company performance – the term material being the key one. If you want some further reading, here is guidance from the ASX around this concept: ASX Guidlines
