Singles Day Sales Data!, page-159

Not sure of its veracity but this from an AFR article on Myer:

In the absence of either company guidance or analyst consensus for the half-year, the ASX's yardstick is the previous corresponding period and listing rules require Myer's board to update the market as soon as it's aware it will fall short of underlying profit (not revenue) by between 5 per cent (arguable) and 10 per cent (mandatory).

From memory a couple of years ago an ASX company (FXL?) who hadn’t provided guidance updated the market because consensus profit expectations were at least 10% higher than internal data projected. Caused a stormy debate on HC as to whether the disclosure was necessary.
