Hellenic Exchanges (HELEX), the operator of the Athens bourse, will reduce charges imposed on investors and listed companies in a move aimed at boosting its competitiveness. Portfolios worth up to 15,000 euros will no longer be subject to a fixed charge, benefiting 220,000 investors, HELEX said. The previous charge-free limit stood at 3,000 euros. The commission paid on transactions by investors will also be reduced as will charges to companies for share capital increases. HELEX is able to reduce charges thanks to a ‘significant’ reduction in operating costs in recent years, said HELEX CEO Spyros Capralos. The lower charges are applicable as of July 1. The company did not provide any estimate on the impact the lower charges will have on revenues.
