Its impact is more observable on the capital market and the indices. The indices are dropping down and the markets are following the same trend. The NSE NIFTY has been the worst hit among the Indian stock market indices. The other sectoral indices are also following the NIFTY until a renewal in the last quarter. Because of the lessening trends in the capital markets, the investors are in a predicament whether their investments will be safe or not. Even though the condition has calmed a little bit now, still there is an obscurity among the investors about the performance of the indices. In this backdrop, an effort was made to study the performance of the sectoral indices in evaluation with NIFTY. The author has taken the data of the last financial year and studied the co integration to establish the relationship between the selected sectoral indices and NSE. Six leading sectoral indices were taken for the analysis, which have a significant impact on the total economic situation of the country. KEY WORDS: NSE NIFTY, sectoral indices, investments, Co-integration.
