RBS maintains its positive stance on luxury fashion group Burberry, despite shares taking a hit over the last few days on concerns of its exposure in Japan.While Japanese consumers have accounted for as much as 40-50% of domestic- and international-related luxury goods demand over the past decade, Burberry's 2011 regional sales exposure is around 5-6%, compared with French company Hermes which has the highest exposure of 19%, according to the broker."Clearly, luxury goods share price performances are likely to be adversely impacted by the recent tragic events in Japan," he says. However, "the share price movement this morning (-5%) appears an over-reaction relative to peers," says Guy.While the broker acknowledges that around two thirds of revenues and earnings are driven by Burberry's Japanese licence business, it notes that the financial impact for the current twelve month period is less of an issue as the group is already more than 11 months through the year.RBS remains a 'buyer', with a target price of 1,500p.While UBS keeps its 'neutral' rating on funeral home operator Dignity, it upgrades its forecasts as pre-arranged funerals should lead growth in the near future.The full year 2010 results were slightly better than expected, with a 2% beat in operating profit as a result of better-than-expected profits from the pre-arranged funeral plan division, according to analyst Isabel Green.The broker ups its earnings estimates for 2011 and 2012 by 3% and 4%, respectively, to reflect the higher base for funeral plans and a slightly lower tax rate than previously assumed."We see Dignity's pre-arranged funerals as an important driver of the future growth of its funeral service business, pulling in an additional 84 more funerals per 100 than would naturally fall to Dignity's branch network," says Green.The target price is increased by 4% to 735p, from 700p, in line with the upgrades.Credit Suisse remains positive on AMEC despite nuclear sentiment providing a drag on the shares recently, after the Japanese earthquake on Friday caused explosions at the Fukushima Daichi nuclear power plant.Shares in AMEC - the international engineering and project management firm - were down 3.2% on Monday, whereas the oilfield services sector as a whole was down just 1.2% after the explosions.However, the broker estimates that current and future nuclear new build revenues account for just 2-3% of the group's earnings per share (EPS) estimates to 2015. "If this were zero, we would still have AMEC achieving 114p of EPSE in 2015 in our base case, higher than the company's target of 'greater than 100p,' " says analyst Tao Ly.Nevertheless, going forward, AMEC's largest nuclear new build exposure is in the UK, according to Credit Suisse, where the company will support EDF's four new build reactors at Hinkley Point and Sizewell. The broker notes that the biggest risk there is the potential for political delays.With the risks limited, the broker keeps its 'outperform' rating and target price of 1,180p.
