A Can Incifin 465innovations In Contemporary Financeproject 8: Option Strategy Reverse Engineering In this project you will reverse engineer an option strategy. You will determine what financial instruments to utilize in order to create the option strategy. The client informs you that he wants to buy a stock which costs $10 per share right now. He would like a portfolio payoff diagram as seen below.
You are asked to combine this stock, call options (purchase or write), put options (purchase or write) and create the portfolio payoff diagram below (the absolute values of all the slopes are 1 in the diagram): Strategy Payoff Diagram S Specifically, you can use 1. The stock (cost of the stock: $. Call and Put options on the stock with Exercise price: $20 (cost of call: $15, put: $. Call and Put options on the stock with Exercise price: $30 (cost of call: $10, put: $. Call and Put options on the stock with Exercise price: $40 (cost of call: $5, put: $.

Answer the following questions in your report:
1. How do you obtain the payoff diagram above? In other words, what portfolio combination leads to the payoff diagram below?
2. What is the cost of this portfolio?
3. Using Excel, create the payoff diagram of this option strategy using the stock prices on the x-axis and calculating the total payoff at those stock prices (Create the graph by using those stock prices in the first column, and the payoffs in the next column. Use Scatter Plot –> Scatter with Straight lines).
Paper For Above instruction
The task of reverse engineering an option strategy to produce a specific payoff diagram requires a comprehensive understanding of how individual financial instruments interact to yield complex payoff structures. The primary goal is to identify the combination of the underlying stock, call options, and put options at various strike prices that replicate the desired payoff pattern.
Understanding the Target Payoff Diagram
The given payoff diagram, characterized by slopes of absolute value 1, indicates a "butterfly" or "striped" type payoff structure, often used to exploit specific market expectations or hedge certain risks. The diagram suggests that the portfolio should have maximum payoff at a specific stock price range, with linear payoffs on either side, creating a symmetrical "V" shape.
Constructing the Portfolio
Given the different options available, with strike prices ranging from $20 to $100, and their respective costs, a combination of these options can approximate the desired payoff. The process involves:
1. Establishing a baseline position in the stock, since the client wants to buy stock at $10 per share.
2. Selecting options at specific strike prices that, when combined, create the piecewise linear payoff.
An effective approach is to build a "spread" strategy involving options at multiple strikes:
- Buying a Call at $60 (cost $4)
- Selling two Calls at $40 (cost $5 each)
- Buying a Call at $20 (cost $15)
This creates a butterfly spread centered around the $40-$60 range.
Additionally, incorporating puts at various strikes can sharpen the payoff or hedge against drops below or rises above certain prices.
Step-by-Step Construction
- Initiate with the stock at $10, representing the initial asset holding.
- Buy a call at $20 for $15 — profits increase sharply if the stock rises above $20.
- Write two calls at $40 for $5 each — caps the upside gains, creating a "roof."
- Buy a call at $60 for $4 — adds asymmetry to the payoff.
- To further refine, incorporate puts — for example, buying a put at $20 for a certain premium if needed.
Calculating Total Cost
The total initial cost involves summing the premiums paid and received:
- Long stock at $10: costs $10 per share.
- Call options purchased: sum of costs at specific strikes.
- Call options written: deduct premiums received for calls sold.
- Puts purchased/written similarly calculated.
Assuming specific options chosen form the theoretical payoff, the total cost might be computed as:
Total cost = Cost of stock + sum of premiums paid for purchased options - sum of premiums received from written options.
From the data:
- Stock: $10
- Call at $20: $15
- Calls at $40: $5 each
- Call at $60: $4
- Put options costs are not explicitly given for all strikes; if they were, similar calculations apply.
Implementing in Excel
To visualize, list a range of stock prices (say, from $0 to $120 in increments of $5). For each stock price:
- Calculate the payoff of each instrument at that stock price.
- Sum these payoffs considering their positions (long or short).
- Plot these total payoffs against stock prices to produce the payoff diagram.
Conclusion
The combination of these options and the underlying stock forms a complex, tailored payoff profile. By carefully selecting options at various strikes and calculating the net cost, one can replicate the specified payoff diagram. This reverse engineering approach allows financial engineers to construct custom strategies aligned with market outlooks and risk preferences. Such strategies exemplify the flexibility and power of options in contemporary finance, enabling precise payoff tailoring.
