Nikkei is a stock market index on the Tokyo Stock Exchange. It is the most quoted index in Japan, similar to Dow Jones Industrial in USA. The downtrend in Nikkei has started in 1990. The recent advance has been a corrective zig-zag (ABC). The triangle in wave four signalized that there is one last movement in the direction of the main trend. Since the completion of wave 5 of C, the trend has reversed.
We think that the main downtrend since 1990 is not yet completed and more down price movement is expected. If the invalidation level remains untouched, we may see a vicious slump in the index.
