The Prague Stock Exchange will switch from both PX-50 and PX-D indices to just one, a PX index as of March 20, the PSE General Director Petr Koblic stated, adding that the newly established index will combine the advantages of the two existing indices. The PX-50 and PX-D will stop calculated on March 17. Koblic explained that the change is linked to the preparation of the planned launch of derivatives trading on the borse. The PX index will include stocks traded on the SPAD system, with market capitalizations above CZK500 million (€17.3 million) and average daily traded volumes above CZK2 million. At the same time, a single issue cannot have a weight of more than 25% in the index.
The new main PX index will continue in the development of the PX-50 index taking over its history. After March, 20 the PX-D index value calculation would be possible using the so called PX-D coefficient, derived by a fraction of the PX-D and PX 50 final values on March 17, multiplied by the PX index value. Meanwhile, foreign stocks listed on other markets will be included in the PX index only if their traded volumes in Prague are high. PSE will disclose the composition of the PX index on Feb. 28.
