The announcement will provide like-for-like sales figures for the past 28 weeks, which Evolution Securities said are likely to show PC World at 7 per cent behind last year.
It said the overall performance at mobile phone shop The Link would also be poor, but added DSG International may have clawed back some ground from its 28 per cent fall in 16 weeks from April 30 to about 16 per cent over the past twelve weeks.
The group's performance is likely to be buoyed by growth in international markets. A resurgent Dixons chain may also offset the weakness at Currys to deliver a 2 per cent fall in UK electricals, said Dresdner Kleinwort Wasserstein (DrKW).
Interim profits to be announced on January 18 will be down by about 20 per cent to£82 million, said DrKW.
On Friday the group restated its accounts for the year to April this year and the six months to November 13 last year to include for provisions under IFRS. The newly drawn-up accounts also included a breakdown of sales and profits for its UK divisions.
