All eyes will be on Tesco on Wednesday when the supermarket giant unveils its half-year results.
News on the impact of the cost-of-living crisis will be uppermost in the minds of many investors.
Derren Nathan, an equity analyst at Hargreaves Lansdown, said: "Tesco prides itself on being price competitive against peers - something that's put it in good stead recently and allowed for continued growing market share.
"Management continues to expect full-year underlying operating profits in the realm of £2.5billion to £2.8billion, but this assumes a return to normal consumer behaviour.
"The question now turns to how the cost-of-living crisis is affecting consumer demand.
"Sales at Tesco's supermarkets have showed resilience, particularly in Europe, but as consumers start trading down to cheaper alternatives we'd like to see what impact this has had on sales at the half-year mark."
Invest-to-save initiative
Mr Nathan also stated that investors will be interested to hear how the company's invest-to-save initiative is going.
He added: "The three-year programme aims to save roughly £1billion and could be the silver lining that gives management confidence in keeping a floor under operating profits. We remain optimistic, but this week should reveal the full impact.
"Shareholder returns will also be on the radar. At last check, the group had already bought back £300million of its shares. The group promised another £750million by April, so progress on this front will be closely watched."
Meanwhile, there will be plenty of interest in a third-quarter trading statement from bakery chain Greggs tomorrow.
Mr Nathan commented: "Greggs has grown impressively since coming out of the pandemic.
"Like-for-like sales for the first half of the year were 12.3% ahead of pre-pandemic levels, but large city locations have continued to lag.
Greggs has strong presence
"While Greggs strong presence in towns and suburbs has helped offset this, we'd like to see transport-hub locations recovery.
"Management said price hikes haven't taken a bite out of volumes yet, but the impact could take time to filter through. Tomorrow should provide a clearer picture.
"Profits haven't seen the same sort of growth, though.
"The group estimates cost inflation to be running at 9% for the full year, and the trading statement should shed some light on how this may impact the outlook going forward.
"This week will also give us an insight into Greggs' expansion plan.
"The group is focused on opening stores in strategic locations like airports and railway stations in a bid to attract a higher footfall of customers.
"We'd like an update on progress here, and some idea of whether rising costs will keep a lid on the pace of expansion."
