Hanfa said that it would give no additional comments on the circumstances until the expiry of the temporary suspension.
Earlier on Monday, Hanfa said that trading circumstances and the available data on investors which it had collected during the continuous supervision were the reason why it temporarily suspended the trading in INA shares "in order to protect all investors and ensure regular and fair trading on a well-regulated market."
Last week, INA shares turned over HRK 13.8 million, with the price rising 1.39 percent to HRK 4,010 per share on the week.
According to a notification which Hanfa sent to the ZSE, the agency said that during supervision of the trading it established a large-scale trading in INA involving foreign investors and that it had requested relevant foreign regulators to provide data pertaining to this case.
