Panmure Gordon has lifted its price target for retailing group Next from 3,770p to 3,848p following the company's Christmas trading update on Thursday morning which showed 'continued strength'.However, despite the forecast upgrades, Panmure retained its 'hold' rating for Next. "Trading on a FY2013E price-to-earnings ratio of 13.5 on our new estimates, dropping to 12.3 in FY2014E, we think that Next shares have some upside but not enough to justify a 'buy' recommendation," analysts said.Seymour Pierce has upgraded its rating for information services company Experian from 'reduce' to 'add' on the back of increased hopes about the US mortgage market.She said that Experian's shares are now trading at "more attractive levels", having underperformed the wider market by 6% over the past month.Investec has reiterated its 'buy' rating and 280p target price for defence contractor Chemring following Thursday's appointment of a new Finance Director in Steve Bowers."We regard Steve highly and the market should welcome a further strengthening of the executive team charged with steering the group after a difficult year," the broker said.
