This week many companies will reveal their Christmas trading figures, which should give a clearer picture of the general sales activity over this period. Last week we saw good figures from Majestic Wines and Waitrose, but poorer trading results reported by Marks & Spencer.

On Tuesday this week Morrisons will give its trading statement for Christmas trading. Investors are expected to focus on sales at the group’s newly converted Safeway stores, according to newspaper reports today. A 10% slide in sales for these stores has been predicted by some brokers, while at the Morrisons fascia a like-for-like sales growth of 5 to 7% is expected for the Christmas period.

Richmond Foods will produce a trading statement on Wednesday, while supermarket chain Sainsbury will report on its Christmas trading figures on Thursday this week.

Geest, the food group being taken over by Icelandic group Bakkovor, will issue a pre-close trading update on Friday. It is expected to report full-year pre-tax profits of £41.8m, according to newspaper reports.

Also on Friday, Uniq, the chilled prepared food manufacturer at the centre of a £230m bid approach, will deliver its post-Christmas trading statement.
