For the last 10 years, stock exchanges from several countries have been searching for alliances or implementing new corporate governance rules in order to protect minority shareholders. The Novo Mercado (New Market) was created by the Brazilian stock exchange, BOVESPA, in this context, inspired by the German Neuer Markt. By adhering to Novo Mercado rules, firms guarantee a higher level of minority shareholder protection, which should lead to an increase in stock prices and, as a consequence, on firm´s financing capacity through capital markets. Using a sample of 46 Initial Public Stock Offerings at BOVESPA from 1994 until 2006, we find that companies that list their shares at Novo Mercado sell, on average, a bigger fraction of their capital (9.52% more) when compared to those that list at other segments in BOVESPA. Our study also shows a benefit of Novo Mercado that has not being much discussed. Higher stock prices make it less costly for controlling stockholders to diversify their wealth. The Novo Mercado seems to be as relevant for financing companies as for diversifying shareholders´ portfolios.
