On 4 May 2009, the Warsaw Stock Exchange will begin publishing two new indices - WIG20short and WIG20lev.
Both indices will be based on the WIG20 index. The movements of WIG20short will reflect the inverse of the WIG20 changes, e.g. a 10pts gain of the blue chip index will translate into a 10pts loss of the WIG20short index. The second newly introduced index, WIG20lev, will change in the same direction as WIG20 albeit with twice the magnitude, e.g. a 10pts rise in the blue chip index will mean a 20pts gain in WIG20lev.
