FTSE 100: Rexam rises as puts personal care business up for sale Volumes on the FTSE 100 were thin, highlighting concerns among investors about injecting cash into the market when fears about longer-term issues over Europe's debt situation remained, and the index fell 18.5 points to 5,909. Leading the laggards was Vedanta Resources as the miner succumbed to profit-taking, falling 4.4pc. Supermarket giant, Tesco, came under pressure, easing 1.6pc as Bank of America-Merrill Lynch switched its rating to "underperform." "Tesco has format and brand/offer issues in the UK that will take time to fix; and international performance remains mixed," said analysts. Further down the market, Cove Energy soared 24.8pc as Royal Dutch Shell - down 0.2pc - made a £992.4m bid for the explorer. Shell has offered 195p-per-share in cash, which Cove's directors said they would recommend to shareholders. "The 195p proposed offer is unlikely to face a challenge in our view and, having been longstanding fans of the Cove story, we downgrade to Hold," said analysts at Investec. There may be more bids in E&P-land. In terms of laterals, we expect further acquisitions and highlight Ophir and Gulf Keystone as the two most likely bid targets in our view," they added.
