A regular client calls you, concerned about a sharp market dip, and asks for a hedge on their Rs. 15,00,000 equity portfolio. You calculate the beta and the required number of index futures contracts, arriving at a result like 7.6 contracts to perfectly neutralize the risk. In your office in Mumbai, you immediately face the practical wall: the exchange does not allow you to purchase 0.6 of a contract.
This limitation is not merely a technicality; it is a fundamental constraint in the execution of risk management strategies for retail and HNI investors.
As a distributor, you must explain to your client that index futures are traded in fixed lot sizes, which introduces a ‘rounding error’ in any hedging strategy. If you round down to 7 contracts, your client remains slightly exposed to market volatility, a state known as under-hedging. Conversely, if you round up to 8 contracts, the portfolio becomes over-hedged, and the client essentially takes a directional speculative position against the market. Neither scenario is ‘wrong’, but both require clear disclosure and prior agreement as part of the suitability assessment process.
This constraint becomes even more critical when managing smaller portfolios or when the SIF investment strategy being hedged has a higher degree of concentration. You must guide the client through the trade-off between the cost of the extra contract and the tolerance for residual risk. Ignoring this fraction effectively means your recommendation is imprecise, which could lead to client dissatisfaction if the market moves in a way that the ’leftover’ fraction amplifies losses rather than mitigating them.
Always document the rationale for the rounding decision in your client’s file to ensure transparency under the current SEBI guidelines for fair dealing.
Ultimately, the art of the hedge lies in acknowledging that theoretical perfection is rarely achievable with standard exchange-traded lots. By framing the fractional issue as a part of the professional execution strategy, you position yourself as a detail-oriented advisor rather than just an order-taker. Mastering the math of the hedge is only half the battle; communicating the reality of market execution is what truly builds professional trust.

A client has a portfolio worth Rs. 25,00,000 with a beta of 1.2. An Nifty index future is priced at Rs. 5,00,000. How should a distributor approach the fractional result if the calculation yields exactly 6.4 contracts?
Which of the following is a primary consequence of rounding down a hedge calculation for an equity portfolio?
