January 24 (SeeNews) - The Croatian share indices on Thursday gained ground, after four days of losses, thanks to rebound on key European markets, brokers said. "The popular benchmark, CROBEX, closed at 4,502.7 points, up by 2.1%, driven by recovery on all major European markets," Neven Salamon, an analyst with Zagreb-based Fima Fas consultancy, said. However, the Zagreb bourse recovery was milder compared to the rebound seen in Asia and Europe, he added.
