So SFH internal reporting systems are of such quality and standard that it takes 18 days post end of quarter to assess quarterly performance and make broad projections on operational performance for 1H'18 (as noted by natnicnak, there are likely to be a myriad of "one off" adjustments likely to blow this number out of the water) and extrapolate this into 2H'18 based on average historic 2H performance - or so it seems.

In those 18 days, the share price moved from 30.5 cents to 25 cents - a drop of just over 18%.

I am just guessing here, but I suspect that management had the data and their projections ready well before today. Only the continued fall in the share price might have forced their hand to finally release a trading update and once again have the market fully informed.

I just wish I could live in somewhere in a parallel universe, where it is like second nature for companies to release this information regularly and in a timely manner. This would not necessarily change the operational trading result, but it would avoid the reality or perception of the market trading while not being fully informed, which to me is a fundamental requirement for investors to have trust in system.

Just IMHO.
