Approachyou Need To Read Chapter 4 Of Chance And Brooks Option Prici

Read Chapter 4 of Chance and Brooks (Option Pricing: The Binomial Model) prior to attempting the coursework. This coursework involves downloading relevant options and market data, performing calculations such as put-call parity, comparing market prices with theoretical models, building binomial trees, and analyzing implied volatility. The process requires extensive use of Excel, organized data collection within a 15-minute window, and critical interpretation of the results. The final report should be 1500 to 2000 words, accompanied by Excel spreadsheets or snapshots illustrating calculations, and include well-referenced citations.

The efficient and accurate pricing of options is a fundamental aspect of financial markets, enabling investors and traders to make informed decisions based on theoretical and market-derived data. The coursework outlined here emphasizes analyzing options on the S&P 100 index, using the binomial model, Black-Scholes model, and actual market data. This comprehensive approach integrates empirical data collection, theoretical computations, and critical interpretation, fostering a deep understanding of option pricing mechanisms.

Preliminary to any analysis, it is crucial to acquire accurate and timely data. This involves downloading prices for European and American call and put options, the current level and volatility of the S&P 100 index, the dividend yield on the index, and risk-free interest rates. All data must be collected within the same 15-minute window to ensure consistency, given the delayed publication of CBOE data. The data collection process should be familiarized with in advance to facilitate swift execution during the narrow time frame.

The data sources include CBOE for options prices, index level, and volatility indices; etfdb.com for dividend yields; and Bloomberg for risk-free interest rates. Once data is acquired, calculations of key parameters such as time to maturity, implied volatility, and the theoretical fair prices of options are necessary. For time to maturity, the precise contract specifications can be checked on the CBOE website, where options expire on the Saturday following the third Friday of the maturity month. Notably, the options should encompass a variety of strike prices representing at-the-money (ATM), in-the-money (ITM), and out-of-the-money (OTM) options, including both European and American types.

In analyzing the data, the first step is to verify the put-call parity condition for European and American options, interpreting deviations as potential market inefficiencies or transaction costs. Next, the difference in prices between American and European options with identical maturities and strike prices is calculated to understand the effect of early exercise features. Presumably, American options command a premium over their European counterparts, especially for ITM options, due to the possibility of early exercise.

The theoretical valuation involves applying the Black-Scholes model to the selected European options, incorporating current index levels, volatilities, interest rates, and dividend yields. Comparing these theoretical values with market prices reveals the extent of market inefficiencies or model limitations. Disparities could stem from volatility smile effects, market frictions, or liquidity issues.

Building the binomial model with three time steps entails dividing the time horizon of the options into equal segments, with upward and downward movements determined by volatility estimates, such as those derived from the VXO index. Automated computations of the binomial tree enable evaluation of American and European options under risk-neutral measures, allowing comparison with actual market prices. Differences may arise from model assumptions, discrete time steps, or market frictions.

Contrasting the Black-Scholes and binomial prices provides insights into model suitability for different option types and moneyness levels. Furthermore, calculating implied volatilities by iteratively adjusting the volatility parameter until the theoretical price matches the observed market price enables the creation of implied volatility plots across the range of strike prices. Such plots facilitate a discussion of volatility surface dynamics, deviations from the VXO index, and implications for market expectations.

In conclusion, this comprehensive analysis synthesizes empirical data, theoretical models, and market insights to deepen understanding of option pricing. Critical interpretation of discrepancies and model assumptions forms the core of this coursework, reflecting both the strengths and limitations of the binomial and Black-Scholes models in real-world markets.
