S&P BSE Mid Cap and BSE Small Cap Index


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

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