Next week sees the opportunity to gauge the relative trading patterns of supermarket giants Tesco and Sainsbury.Tesco's interim figures on Wednesday are probably the more eagerly awaited, given the recent change in strategy of the company in favour of an "every day low prices" strategy rather than a promotions-led strategy, such as the double Clubcard points offers the firm has provided in the past.The interesting question is whether the change in tack is simply a case of relatively new chief executive, Philip Clarke, continuing to put his stamp on the company, or whether it is a case of Tesco desperately trying to prevent its UK market share falling below the psychologically important 30% mark.There have been suggestions that Tesco has taken its eye off the ball in its home market, because it sees greater growth opportunities overseas. The interim report may provide detail on how well the overseas operations are doing, especially the US Fresh & Easy venture, which is beginning to hit its stride after a faltering start.On the economic front, both the Bank of England and the European Central Bank will be announcing their interest rate decisions. Though there has been talk of the Old Lady of Threadneedle Street cutting its benchmark interest rate from its historic low level of 0.5%, the chances of that happening this month are close to zero. There is more prospect of the Bank reviving its quantitative easing programme, though that is also a bit of a long shot.As for the European Central Bank, many are expecting the policy makers to admit they raised interest rates too soon earlier in the year by reversing course and announcing a rate cut.
