Ann: Change of Director's Interest Notice - J Graham, page-24

A company director is legally allowed to purchase shares on-market provided it is outside blackout times which normally relate to price sensitive announcements. I dont know the exact rules but would assume the fact James bought on market would mean there should be no market sensitive announcements in the near future unless it is out of the blue and he can prove he had no prior notice.

Not sure if you are unhappy with directors trading and having inside knowledge but that is why they have to announce a change in holding to market, and many people follow director on market purchases for this exact reason ie we assume they know something and if they are buying it must be good??
Same but opposite if a director is selling shares- time to bail generally.
