"Companies are cashing in by not lowering prices as Supply issues resolve - margins increasing?"

In the short term, inflation helps revenue and gross profits (supermarkets buy an item apply the usual mark-up and flip it)

Longer term, supermarket operating costs start feeling the pressure (staff, rents, electricity etc) which pushes profits down.
Also longer term, consumer buying power starts feeling the pinch (though not as much for grocery staples)

So its a number of forces, some positive some negative, mostly negative

Anyway, the Woolworths result was within expectation, and its now history.
As discussed yesterday, the market only cares about the future.
