This is a bundled pre-market wrap, but the lead item is the Coles quarterly sales update, and the framing is the familiar one: the Australian supermarket duopoly is read relative to itself, and the gap in comparable sales growth between Coles and Woolworths has historically driven the relative trade in the pair more than the absolute print. Episodes where one operator's comp growth lags its rival have tended to reopen the execution and price-investment debate, with the laggard's margin guidance carrying the weight; here the H1 supermarket EBIT guidance of flat on the prior year, despite flagged fuel cost headwinds, is the line that sets up the interim result. Liquor revenue declining while supermarkets grow is also a recurring pattern in this name and is usually treated as a separate, lower-multiple issue. Elsewhere in the wrap the distinguishable items are ResMed, where an earnings beat with gross margin holding above prior levels has historically been rewarded given the market's focus on competitive pressure in sleep devices, and Rio Tinto's suspension of underground operations at Oyu Tolgoi, where past mine stoppages have been priced off duration and guidance language rather than the announcement itself. Origin's APLNG realised price and Pinnacle's net inflows are the data points most likely to be folded into existing commodity and funds-flow narratives rather than repriced on their own. The follow-ons of note are any Woolworths response or update, management commentary on the comp gap drivers, and clarity on the Oyu Tolgoi restart timeline.
