With the bulk of the Christmas trading updates from major retailers out of the way, Friday looks set to be a quiet day, with results from Bovis Homes likely to be the most keenly anticipated corporate update.The company moved back into the black last year and was still sounding cautiously optimistic as recently as November. "Whilst there remains uncertainty concerning the near term direction of house prices, the fundamental demand and supply drivers of the housing market remain positive which should support volume and prices in the medium term," the group said in its interim statement.Bovis said in November it expects the average sales price of legal completions in 2010 will be around £160,000, up 3% from 2009's average sales price of £154,600, so Friday's trading update should reveal how accurate that prediction was.On the economic front, UK producer input prices for December are tipped to have risen 1.70% in December, after rising 0.90% in November. Output prices are expected to have risen 0.40%, versus November's 0.30% increase.The jump in the input prices index is likely to be due to rises in commodity prices, particularly food and oil.
