It is often the case that one year's underperformers in the stock market are the next year's best, but no so year-to-date. Thus, the main high street banks' shares are leading gains today after analysts at UBS pulled out their spread sheets this morning and raised their price targets for the main High Street banks, Lloyds (to 60p from 50p), Barclays (to 315p from 255p) and RBS (to 410p). That comes in anticipation of an expected improvement in mortgage lending and a reduced need to raise capital after the Basel committee on banking supervision last Sunday eased financial institutions' liquidity requirements. The result, which has 'read-across' to other countries is that "Britain's experiment of combining fiscal and monetary asterity may be over and the incoming Bank of England governor's openness to monetary policy innovation may not even need to be tested if," as UBS expects, banks return to lending. On a more realistic note - sombre even - plenty of long-term policy challenges remain. Thus, in its latest risk assessment the World Economic Forum (WEF) warns that severe income disparities, the indebted state of governments and rising greenhouse gas emissions risk a global "perfect storm" of intertwined financial and ecological collapse. This is not news really, but public awareness is still a tad limited. Sainsbury fails to meet lowered expectationsSainsbury has unveiled a +0.9% like-for-like increase in sales excluding fuel. That was below the 1.0% rose consensus expected, which was already down on the 1.5% rise which analysts had been pencilling in before the New Year. "We suspect Sainsbury will struggle to outperform in 2013 as Tesco continues its fight back and there is some margin vulnerability as momentum slows," Seymour Pierce analysts said in reaction.House builder Galliford Try has announced that it remains on track to meet its full year expectations and that half year profit is ahead of its targets. Designer brand Ted Baker announced a solid rise in sales over the festive period as Chairman Robert Breare confirmed he will step down after more than 11 years in the role. David Bernstein, currently Senior Independent Non-Executive Director, will succeed Breare with immediate effect.
