Morrison, Debenhams and WH Smith all making statements today. Wm Morrison edges higher after the supermarket made a good start to the new trading year, with sales growth well ahead of the sector norm. Like for like sales improved by 8.2%, or by 5.0% including fuel, maintaining the rate of LFL growth seen in the year to 1 February 2009. Sector peers Sainsbury and Tesco rise in sympathy with Morrison. Department store Debenhams is to raise £323m through a placing and open offer to reduce its debt burden and improve its ability to acquire retail assets that may arise if the economic downturn persists. It said its high debt levels had damaged investor sentiment towards the company, which has impacted its share price. The company had been widely expected to raise funds through a share issue, but with the price at which the shares are to be sold yet to be determined, the market has adopted a cautious stance and marked the shares lower. Newsagent WH Smith is also on the slide after said like-for-like sales in the first 13 weeks of the second half were down 4% on the same period last year, with total sales up 1%.
