Diversified Gas & Oil (DGOC), the largest oil company on AIM and an enterprise whose accounts are being scrutinised by the FRC for a wholesale breach of IFRS guidelines, has announced it plans to move from the Casino to the Premium segment of the Main Market of the London Stock Exchange in Q1 2020. Both Avanti (AVN) and Quindell (QPP) made similar promises to try to keep their shares afloat. Neither actually made it off AIM as promised although, several years later, an almost bankrupt Avanti will be delisting altogether.
