Diet time for Danone

Danone's shares rose 5 per cent after the company released better than expected fourth-quarter results. However, the French group's dairy business in Europe has been hit hard by falling sales. In response Danone announced plans to save €200m, including the loss of 900 jobs, and aims to have slimmed down by the end of 2013. Lex's Stuart Kirk and Oliver Ralph consider if this deadline is achievable and whether shares are overvalued.
