We are therefore not surprised that Anadarko is taking a serious look a Rockhopper," said Merchant analyst Brendan Long. Long added that any investment from Anadarko would represent an American interest which would dispel political risks.Merchant Securities has maintained its 428p target price on Rockhopper.Prime Markets recommends to buy shares of Hunting ahead of its results in March as the oilfield support services provider revealed on Monday that full-year figures are set to be above expectations."Investors that held or chased down their holdings in Hunting Plc during the crash last August and the acquisition of Titan and WL Doffing will be glad they did, as Hunting continues to prove its mettle as one of the world's leading upstream oil and gas companies," according to the head of dealing at Prime Markets, Richard Curr.Prime Markets gives Hunting a target price of 900p.BC
