Until then, both indices will be published in parallel.

The new index lists the 30 largest and most liquid companies from 13 industries, and further to a decision taken by the WSE Management Board on August 8 2013 it will also include Grupa Azoty and Synthos as representatives of the chemical industry. Being a constituent of the WSE’s main index has been one of our strategic objectives.

Composition of the WIG30 index is determined based on the value of a portfolio of the 30 largest and most liquid companies listed on the main market of the WSE. The base value of the index was set at 2,582.98 points as at December 28 2012.

Being a price index, WIG30 reflects prices of share transactions but does not account for dividend income. Its portfolio may contain no more than seven stocks from each sector represented on the exchange, and each company’s share in the index capitalisation is capped at 10%.
