I may be over thinking this but does this mean major milestones achieved are held onto by mgt and disclosure Delayed until Tuesday. I understand they have to prepare announcements and this takes time but surely management are holding this information longer than they have to by setting a consistent announcment date meaning more risk of the information being leaked before being disclosing to the market. I’m just baffled as the consistency of Tuesday announcements or could this be some big coincidence.... comments?
