CIECH S.A. shares are included in the new, prestigious index of the Three Seas region stock exchange

CIECH S.A. shares are included in the new, prestigious index of the Three Seas region stock exchanges, which will include the largest and most liquid companies listed on individual markets of the Visegrad Group, Croatia, Romania and Slovenia. The WSE will be responsible for its calculation.

The index portfolio will include more than 100 of the most liquid stocks of companies listed on Central and Eastern European exchanges in Bratislava, Bucharest, Budapest, Ljubljana, Prague, Warsaw and Zagreb. Stocks participating in the index have to meet the liquidity criterion: average value of trading per session of at least EUR 90,000 in six months period.

The participation of stocks in the index will depend on their free float and will be capped according to the 5/10/40 rule (i.e. participation of the biggest stock is capped at 10%, aggregate participation of stocks weighing more than 5% is capped at 40%). The participation of stocks from any single country in the index portfolio will be capped at 50% (in practice, the cap applies only to stocks listed on GPW).

The new index will be published daily basing on closing prices converted at the exchange rate of the National Bank of Poland for local currencies, the euro, and the US dollar. The Warsaw Stock Exchange (GPW) will be responsible for the calculation and publication of the index.
