The new index measures the performance of the top 20 mid-cap companies selected based on free-float market capitalisation. It is designed to offer concentrated exposure to leading mid-sized firms rather than the broader midcap universe.

According to the exchange, BSE will introduce cash-settled monthly index futures and monthly index options on the new benchmark. Contracts will expire on the last Thursday of the expiry month, in line with the standard monthly derivatives cycle.

The approval comes amid recent regulatory changes that have streamlined the derivatives framework. Following Sebi’s directives, exchanges now offer only one weekly expiry per exchange to curb excessive speculative activity and reduce concentration risk.

This has effectively reduced the number of weekly index options expiries available in the market, shifting greater focus to monthly contracts and select flagship indices.

The launch of derivatives on a focused midcap index could attract traders and investors seeking targeted exposure to quality mid-sized companies, especially in a market where broader midcap indices have seen sharp swings.
By introducing a concentrated 20-stock midcap benchmark, BSE is positioning the product as a tactical tool for hedging and directional strategies linked to midcap performance, while adhering to the revised derivatives structure emphasising monthly expiries.
