The popularity of a listed company is certainly given by the number and value of securities that are traded. In the first months of 1987, Unipol largely leads this ranking, and each month approximately 13% of the Company’s preference shares are traded, a much higher percentage than other listed companies, also because trades are also higher in absolute value than the securities that follow Unipol in the ranking.
