The first index of BSE-Sofia is SOFIX, which calculation started on October 20, 2000. SOFIX is based on the market capitalisation of the included issues of common shares, adjusted with the free-float of each of them.
SOFIX is the most successful index calculated by BSE-Sofia and is the first one on which structured products are based on.
BG 40 covers 40 issues of common shares of the companies with the greatest number of transactions and the highest median value of the daily turnover during the last 6 months as the two criteria shall have equal weight. The calculation of BG 40 started on February 01, 2005.
In an effort to provide a broader picture of the Bulgarian capital market, BSE-Sofia started the calculation of two new indices in September 2007.
The first one, BG TR30, is based on the price performance of the common shares included in the index portfolio, as each constituent issue has equal weight.
The second, BG REIT, covers 7 issues of common shares of special investment purpose companies that operate in the field of securitisation of real estates and/or land, i.e. real estate investment trusts (REITs), with the greatest market value of the free-float and the highest median value of the weekly turnover during the last 6 months.
