Profit taking saw Cairn Energy touch 1,455p before closing 37p off at 1,500p. Investors cannot be blamed for trousering profits. Cairn has been one of the success stories of 2004. It has soared from 365p in January after finding the Mangala oil field in the deserts of Rajasthan. Cairn snapped up acreage rejected by Shell, paying about £10m for assets now valued by the stock market at about £1.5bn following a string of finds.
