Upgrading the stock to overweight from underweight and raising its target price by 90p to 990p, the broker said recent shareprice underperformance, bleak prospects elsewhere in the sector, increased confidence because of GUS's strategic review and the possibility of a £1bn-share buyback were behind its more positive stance. GUS, which owns Argos and Experian, rose 12½p to 913⅓p.
