As of today, BM&FBOVESPA begins the real time calculation and publication of the Corporate Governance Trade Index (IGCT), the Exchange’s 18 th index. IGCT will calculate daily the performance of shares issued by companies that have voluntarily adopted differentiated corporate governance standards and which meet the inclusion standards that have been established by the index’s methodology.
The new index will be updated every four months, and is different to the IGC in that it considers liquidity criteria such as inclusion in a group of stocks whose negotiability indices added represent 98% of the total value of all individual indices; and trading session participation equal or more than 95% in the period.
The same company can have more than one stock in the portfolio, as long as each stock meets the inclusion criteria separately. What is more, companies with less than 12 months of listing are only eligible if they have more than six months of trading and have at least 95% presence in the trading session during the last six months of the analysis period.
