This study has carried out somepreliminary
time series analyses to examine the impacts of demonetization which was carried
outin India on 8 November 2016, on the well-known Indian stock index,
BSESENSEX,and four major sectoral indices viz., BSE BANKEX,BSE Auto, BSE Reality
and BSE Smallcap,using daily level time series data covering the period 1January
2016 to 31May2017. Apart from examining the stationarity/nonstationarity
property and existence of structural breaks after demonetizationin these series,
the paper has also studied the trend behavior and returns models for both the
pre- and post-demonetization periods. This study has
found that while there is more than one break in all the five series at their
level values, there is only one structural break after demonetization.  It has also been found that the trend
function for all the index series broadly gives support to this finding of one break
after demonetization. Further, some changes have also been observed in the
stationary models for the two sub-periods of pre- and post-demonetization for
all but BSE Auto index. Finally, except for BSESENSEX to some extent, no change
in the status of stationarity/nonstationarity in the pre- and post-
demonetization periods has been found in the other series.
