S&P BSE MIDCAP

BSE introduced the new index series called 'BSE MID-Cap' index and 'BSE Small-Cap' index to track the performance of companies with relatively smaller market capitalization.

BSE-500 Index - represents more than 93% of the listed universe. Companies with large market capitalization bias the movement of BSE-500 index. This necessitated construction of a separate indicator to capture the trend in companies with lower market capitalization. Over the years, BSE Mid-Cap and BSE Small-Cap indices have proven to be a great utility to the investing community.
