Tesco’s market share for the 12 weeks to 10 October was 28.1%, compared to 26.6% in the year-ago period. Asda meanwhile grew its market share from 16.6% a year earlier to 16.8% in the latest period.


Sainsbury’s market share was 15.4% in the latest period, down from 15.8% a year earlier but up slightly from the 15.3% achieved last month.


“Yesterday, (Sainsbury’s CEO) Justin King set out his plans that included rectifying availability problems, more competitive pricing, and strengthening in-store staffing and service levels.  This should go some way to correcting basket size weakness which is behind the current poor share performance,” said Edward Garner, communications director of TNS Superpanel.


“Now that the conversion of Safeway stores to the Morrisons fascia is well underway, the Safeway decline has accelerated with a share falling to 6.3% for 12 weeks ending October 10 2004 from 8.8% a year ago. This fall is not yet being matched by a corresponding rise in the Morrisons share, which has risen from 5.9% to 7.1% over the same period.  The net effect is that the combined fascias have declined from 14.7% to 13.4%.  The key question is when will this decline halt and the proven merits of the Morrisons strategy bear fruit,” Garner added.
