Collar

Strategy Structure

Hold the underlying + Buy 1 OTM Put (protection) + Sell 1 OTM Call (to fund the put).

Profit & Loss Profile

Market Outlook

Neutral — protecting a holding through uncertainty while accepting limited upside.

When to Use

• You want protection but don't want to pay the full put premium
• You are neutral-to-mildly-bullish and fine with a capped upside
• You want to lock in a defined range around unrealized gains
• Ahead of binary events (results, budget, policy)

When to Avoid

• When you expect a large rally (the call cap will hurt)
• If you want to retain full upside (use a protective put instead)
• In strongly trending markets where the range is too restrictive
• When the call premium is too small to meaningfully fund the put

Ideal Conditions

• You hold the underlying and want cheap, defined protection
• You are willing to cap upside in exchange for funding the put
• Ahead of an uncertain event where you want to define the range
• IV skew that makes the OTM call rich relative to the put

Nifty Example

Adjustments & Risk Management

• Roll the short call up if the underlying rallies and you want more upside room
• Roll the put up to lock in gains after an advance
• Widen the collar (lower put, higher call) for more room if your view turns bullish
• Remove the call after a pullback to re-open upside while keeping the put

The Zero-Cost Collar

The most attractive form of the collar is the zero-cost (or even small-credit) collar, where the premium from the short call exactly funds the long put. This lets you insure a Nifty position against a crash for effectively nothing, at the price of capping your upside at the call strike.

Achieving zero cost depends on the IV skew. In Indian indices, OTM puts often carry a fear premium, so you may need to sell a call that is closer to spot than the put is — which tightens the upside cap. Always check whether the resulting range is acceptable before locking it in.

When the Collar Beats a Plain Hedge

A collar is the right tool when you want protection but find a standalone protective put too expensive, and you are genuinely comfortable surrendering the upside above a certain level. It is widely used to protect concentrated positions or to bridge a portfolio through an uncertain stretch like election season or a budget cycle.

If you remain strongly bullish, the upside cap is a real cost and a protective put may serve better. The collar suits the neutral-to-cautious holder who prioritises cheap, defined-range protection over open-ended gains.
