Investors will be keen to hear how Ocado Group PLC (LON:OCDO) is faring under pressure from online rivals when the grocery distributor updates the market on Tuesday.
The City will also be on the lookout for any news of long-awaited partnerships with overseas firms to use the UK company's advanced retail technology.
Numis Securities expects retail sales growth of 13.5% in the third quarter, but says declines in basket value will partly offset that.
The broker's Andrew Wade added: "With recent press coverage suggesting Morrisons could spark another round in the price war, this dynamic looks unlikely to change in the near future.
"More broadly, we will be interested to hear of any impact from Amazon Fresh following its recent launch.
"Ocado shares have had a strong recent run, but we retain our positive stance, continuing to believe that central fulfillment is the right model for grocers long-term."
Elsewhere, Numis said first-half results from Hilton Food Group plc (LON:HFG) should be solid.
Analyst Charles Pick said: "The trading updates of May 25 and July 21 were favourable and indicated that volume growth featured, including in the UK, Holland, the Republic of Ireland and Central Europe."
Broker Peel Hunt expects semiconductor maker IQE plc (LON:IQE) to stick to consensus numbers when it reports first-half results.
IQE released a positive first-half 2016 trading update, reporting at least a 15% increase in revenues including strong growth in photonics, £3.5mln from licence fees and modest growth in wireless and infra-red.
Profit is also indicated to have grown strongly, the broker said. "Our estimates are broadly in line with consensus and we do not expect significant changes to consensus numbers.
"Revenue diversification is a key pillar of the 'buy' case, not just because it reduces exposure to wireless product cycles, but because it is an indication of new structural growth trends."
