Italian stock exchange does not play a relevant role in the national economy. To go public has not been, in fact, a very popular decision for Italian companies for a number of reasons including a cultural resistance of national entrepreneurs, the large diffusion of family businesses, the small and medium size of companies, etc. Only a small number of companies go public despite the commitment of the national stock exchange to favor their access to the financial market.
