Warsaw Stock Exchange expands the index family WIG20, mWIG40 and sWIG80


The WIGPlus index portfolio includes those companies which do not qualify for the WIG20, mWIG40 or sWIG80 index and which belong to the 5PLUS segment, i.e., their average market value in the last quarter was between EUR 5 and 50 million. The first index portfolio was determined on the basis of a ranking as at the end of October 2011.

Unlike the indices WIG20, mWIG40 and sWIG80, the number of companies in the new index portfolio is not fixed: it depends on the number of companies in the latest ranking which fulfil the index portfolio participation criteria. Thanks to its structure, the WIGPlus index is an effective tool to track the performance of the smallest listed companies; combined with the indices mWIG40 and sWIG80, it may serve as a point of reference to assess investment in small and medium-sized companies and as the basis for the structure of investment funds.

The principles of periodical and extraordinary adjustments of the WIGPlus index portfolio and the frequency of its publication are the same as for sWIG80: the list of index participants will be determined after the last session in January, April, July and October; periodical changes will be implemented after the session on the third Friday of March, June, September and December. The share of the largest companies in the index portfolio is capped at 10%; extraordinary adjustments of WIG20, mWIG40 and sWIG80 will result in adjustments to the WIGPlus index portfolio. The current value of the index will be published every minute from the opening until the closing of a trading session.
