UK stocks ended Tuesday's session with small losses, influenced in part by some weaker-than-expected economic indicators from the Eurozone, marking the second day of losses this year. Eurozone unemployment hit a new record high of 11.8% in November, according to official figures. This was a slight rise on the 11.7% rate the 17-nation bloc registered in October. More than 26m people are now unemployed across the EU, with that number totalling 18.8m in the Eurozone. Also of concern was the British Retail Consortium's (BRC) prediction for this 2013. How will 2013 go you say? "Underwhelming" is the BRC's answer. After reviewing the data economists at Barclays Research are of a similar mind, saying that: "With consumer confidence remaining depressed and spending power growth likely to be measured, we do not expect the retail environment to improve significantly this year." Sales at stores open at least a year gained 0.3% in December versus a year ago, the worst performance since 2010, when adverse weather conditions deterred shoppers. Meanwhile, research by a leading business group shows the UK economy grew in the fourth quarter of 2012, despite widespread fears of a triple dip recession. The British Chamber of Commerce (BCC) Quarterly Economic Survey showed a pick up in both the manufacturing and service sectors in the last three months of the year. The survey of 7,662 businesses also found that levels of confidence and investment had increased over the period, despite remaining weak by historical standards. In other news, the session saw Deutsche Bank upwardly revise its price targets for the majority of the construction & materials shares under its coverage, with its favourite picks being Bovis Homes, Barratt Developments and Berkeley Group. The broker raised its price target on Barratt Developments to 278p (from 224p), Bovis Homes to 667p (from 599p) and on Berkeley Group to 1,941 (from 1,925). They explain that, "through 2012 the UK house builder sector re-rated, moving from 0.69 times 2012 Net Tangible Asset Value (NTAV) to 1.0 times 2013 NTAV. However, as the sector reaches returns that cover its cost of capital in 2013, moving to mid teen levels by 2014/2015, we believe a further rerating is available. A sector creating mid teen return on capital employed (ROCE) on a sustainable basis (the upside being based on self-help measures rather than any housing market pick-up) we believe deserves to trade at a 20% premium to its NTAV (mid-range of its 2000-2005 valuation range)."Of possible import, an adviser to China's central bank was cited as saying that it will be more cautious in the second half of the year regarding its monetary policy.

ARM Holdings was also up in the top 10 after Swiss broker Credit Suisse updated its forecasts for the chip maker so as to reflect the changes made to its forecasts for the handset industry in 2013. More specifically, analyst Kulbinder Garcha has raised his smartphone market volume estimates by 6%/15% and tablet estimates by 5%/13% for 2012/13. Sainsbury was seen heading higher as confidence grew ahead of tomorrow's trading announcement, and after data from Kantar Worldpanel showed that it was the only grocer to gain market share these past holidays. Meanwhile, Tullow Oil shares fell after Societe Generale cut its target price on the stock from 1,450p to 1,390p, while the hold rating remained unchanged. Investec also reduced its target price from 1,399p to 1,000p and downgraded the stock from hold to sell. TUI Travel fell after Morgan Stanley downgraded the group from equal weight to underweight. Croda International was also a big faller after Canaccord Genuity reiterated its 'sell' rating on the stock. Debenham's was lower after saying that it now expects gross margin for the year to be 10 basis points higher than last year rather than 20 basis points as previously guided.
