Using the Zivot-Andrews and Fourier unit root tests the stationarity of the series is tested. Since series is found to be non-linear KSS unit root test is applied. The results suggest that the series has unit root we conclude that in case there is an exogenous shock its impact on Participation 30 Index will be permanent.
