STOCKMARKETS in the Gulf do not observe Christian holidays, but still had a generally quiet day on December 25th. Shares in Dana Gas, an exploration business listed in Abu Dhabi, however, did make some noise, leaping by 13.2% on Christmas Day, to complete a buoyant six months for the stock (see chart). The surge may owe something to the company’s recent arbitration victory against the regional government of Iraqi Kurdistan, over $2bn it and its consortium partners are owed in overdue payments. But it also hints at shareholders’ belief that Dana will not be forced soon to satisfy its own creditors. They have been up in arms since the firm refused to honour a $700m Islamic bond, or sukuk, that matured in October.
