NISM Series VIII Equity Derivatives Study Guide: Chapter 5 (Part 2) — Advanced Option Trading Strategies

This section covers Part 2 of Chapter 5, focusing on advanced hedging and income-generation strategies: the Covered Call, Protective Put, Collar, and Butterfly Spread. These strategies are essential for managing existing cash market portfolios or structuring defined-risk volatility trades.

1. Covered Call Strategy

The Covered Call is a highly popular conservative strategy used primarily by long-term investors to enhance the yield of their portfolio.

1.1. Core Concept and Execution

This strategy is used to generate extra income from existing holdings in the cash market. To execute a covered call, an investor:

1. Holds a long position in an underlying stock (cash market).
2. Sells (writes) a Call option on that same stock.

The premium received from selling the call option provides an immediate cash inflow, which acts as a yield enhancer or a small cushion against a minor decline in the stock's price.

1.2. The Strike Price Trade-off

The most important factor in this strategy is the strike price of the sold call option. Choosing the strike price involves a critical trade-off:

• Strike Close to Prevailing Stock Price: If the strike price is close to the current market price of the underlying asset, it will fetch a higher premium upfront. However, this also means the potential upside gain from the underlying stock is locked and capped very early.
• Strike Far From Current Stock Price: If the strike price is set far above the current stock price, it will fetch a lower upfront premium. The benefit is that it provides a "longer ride of money" on the underlying stock, allowing the investor to capture more upside capital appreciation before the gains are capped.

1.3. Risk and Payoff Profile

• Downside Risk: A covered call does not protect the investor from a major market crash. The downside risk remains for falling prices; if the stock price moves down significantly, losses on the stock holding keep increasing.
• Synthetic Equivalency: Because the upside is capped and the downside is fully exposed to the falling stock price, a covered call’s overall risk-return profile behaves similarly to a short put option.

2. Protective Put Strategy

The Protective Put is a fundamental risk-management strategy used to safeguard an equity portfolio from market downturns.

2.1. Core Concept and Execution

An investor who holds a long position in the cash market always runs the risk of a fall in prices. A decline in stock prices leads to a reduction of portfolio value and mark-to-market (MTM) losses.

To hedge this risk, a portfolio manager (such as a mutual fund manager anticipating a market fall) has a few choices:

1. Sell the entire stock portfolio (which can incur high transaction costs and tax liabilities).
2. Short index or stock futures.
3. Buy a Put option on the underlying portfolio assets (the Protective Put strategy).

By purchasing a put option while holding the underlying asset, the investor establishes a guaranteed floor price at which they can sell the asset, effectively eliminating downside risk below the put's strike price.

2.2. Synthetic Relationship

• Synthetic Long Call: A protective put payoff is structurally similar to that of a long call option.
• Why? If the underlying asset's price rises, the investor participates fully in the upside (minus the premium paid for the put), just like a long call. If the asset's price falls, the loss is strictly capped at the put's strike price, also mimicking the limited risk of a long call. Therefore, this combination is referred to as a synthetic long call position.

3. Collar Strategy

The Collar is a multi-leg hedging strategy that brackets an investor's portfolio value between a specific upper and lower bound.

3.1. Core Concept and Execution

A collar strategy is a direct extension of the covered call strategy.

In a standard covered call, the investor faces unlimited downside risk if the stock price plummets (the downside risk remains for falling prices). To put a hard floor to this downside risk, the investor buys a put option.

The strategy is constructed by combining:

1. A Long position in the underlying stock/futures.
2. A Short (written) Call option (to generate premium income).
3. A Long Put option (to protect against downside losses).

3.2. How the Hedge Works

The long put option in this strategy essentially negates the downside risk of the short underlying/futures position or the synthetic short put profile created by the covered call. By selling the call, the investor uses the premium received to fully or partially offset the cost of buying the protective put option, creating a highly cost-efficient hedge.

4. Butterfly Spread Strategy

The Butterfly Spread is a highly structured, neutral option strategy designed to profit from low volatility while maintaining strictly defined risk parameters.

4.1. Core Concept and Execution

Just as the collar is an extension of the covered call, the butterfly spread is an extension of the short straddle.

In a standard short straddle, a trader gains when the market is flat, but faces theoretically unlimited downside risk if the market moves violently in either direction. To eliminate this unlimited risk, the trader buys out-of-the-money protection on both sides.

A butterfly spread is constructed by:

1. Establishing a Short Straddle (selling an at-the-money call and an at-the-money put).
2. Buying one out-of-the-money (OTM) call option.
3. Buying one out-of-the-money (OTM) put option.

This combination caps the maximum loss on both ends of the payoff spectrum, creating a safe, range-bound trade.

4.2. Payoff and Construction Variations

• Visual Profile: The resulting position has a unique pictorial payoff chart that resembles the wings of a butterfly, giving the strategy its name.
• Flexibility of Construction: A butterfly spread can be created using:
  • Only call options.
  • Only put options.
  • Combinations of both call and put options.

5. Payoff and Risk Comparison Matrix (Part 2)

The table below outlines the core characteristics of the strategies detailed in Part 2 of Chapter 5:

6. Important Terminology Glossary

• Covered Call: An income-producing strategy involving holding the underlying asset and selling a call option against it.
• Protective Put: A hedging strategy where an investor buys a put option to protect their existing cash market stock holdings from falling prices.
• Synthetic Long Call: A position created by combining a long asset position with a long put option, producing a payoff identical to a long call.
• Collar: An extension of a covered call that uses a long put to establish a absolute floor on downside risk.
• Butterfly Spread: A defined-risk neutral strategy constructed by adding long OTM options to a short straddle to limit potential losses.

7. Key Takeaways for the F&O Certification Exam

1. Yield Generation: A Covered Call is primarily used to generate extra income from existing holdings in the cash market, but it leaves the investor exposed to full downside risk.
2. Strike Selection Trade-Offs: For Covered Calls, selecting a strike closer to the stock price increases upfront premium but caps stock gains early; a farther strike gives less premium but permits a longer ride of money on the stock.
3. The Synthetic Long Call: Always remember that a Long Stock + Long Put = Synthetic Long Call (Protective Put).
4. Collar Risk Mitigation: A Collar effectively removes the unlimited downside risk inherent in a standard Covered Call by utilizing a long put option.
5. Butterfly Composition: A Butterfly Spread can be constructed using only call options, only put options, or combinations of both. It is used as a safer, limited-risk extension of a short straddle.
