BSE launches long-short and inverse indices to manage equity volatility
Long-short indices combine 80 per cent market exposure with 20 per cent hedge
Inverse indices move opposite to markets, useful for short-term hedging
Signals shift towards risk-managed, strategy-based investing in equities
As volatility becomes a more familiar feature of Indian equities, the tools available to investors are also beginning to change. The Bombay Stock Exchange (BSE) Index Services has introduced a new set of indices that attempt to reflect this shift, moving beyond plain-vanilla market tracking to strategies that account for both upside and downside.
In a press release issued on March 18, the exchange’s index subsidiary announced the launch of two long-short indices and two inverse indices. The products are positioned as building blocks for strategies that aim to stay invested in equities while managing risk in a more structured way.
How The Long-Short Framework Works
The long-short indices follow a fixed allocation model. A dominant share, 80 per cent, is linked to the BSE 500, offering exposure to the broader market. The remaining 20 per cent is assigned to inverse positions in either the BSE 200 or the BSE 150 Midcap indices.
The structure is meant to do two things at once. On the one hand, it captures the general direction of the market through the BSE 500. At the same time, it builds in a cushion, so when parts of the market decline, this portion is meant to move the other way and help limit the hit.
This kind of approach is not new globally, but it has been relatively uncommon in India’s largely long-only ecosystem. By packaging it into an index, BSE is effectively offering a rules-based template that asset managers can use without having to actively manage hedges on a day-to-day basis.
Inverse Indices For Short-Term Moves
Another set of indices introduced alongside this tracks the BSE 200 and BSE 150 Midcap, but in reverse. These are designed to deliver returns that move opposite to their respective indices on a daily basis.
Such indices can come into play when markets turn weak or uncertain. Instead of exiting positions altogether, investors can use inverse exposure as a way to hedge. They could also suit investors who want to play short-term market moves without actually shorting stocks themselves.
That said, because they reset every day, their performance over longer stretches can be uneven, especially in volatile markets. As a result, they tend to be used more for tactical positioning than for long-term allocation.
What This Means For Investors And Fund Houses
According to the press release issued by BSE Index Services, the new indices are expected to serve as benchmarks for specialised investment funds and similar strategies. For fund managers, this opens the door to products that blend passive exposure with elements of risk control.
For investors, this essentially means there are more ways to approach the market now. Earlier, most products simply moved with the index. With long-short and inverse strategies coming in, the focus is also shifting towards limiting losses, not just aiming for gains.
Whether these indices see widespread adoption will depend on how asset managers use them and how investors respond. But their arrival signals a clear direction: the market is beginning to recognise that participation and protection may need to go hand in hand.
