Individual Assignment

This assignment is worth 25% of the final mark for FIN201 Financial Mathematics.

The cut-off date for this assignment is 30 October 2016, 2359hrs.

In this assignment, you are expected to:

 Use a computing tool (e.g. Excel/Google Spreadsheets or Python) for financial calculations.

 Use a financial information system (e.g. Reuters Eikon, or the Internet) for obtaining market data and information as well as harnessing well-documented API/library/models to make inferencing more expedient.

Question 5

Answer the following questions on option pricing.

(6 marks)

(b) Suppose that the stock price of a company X is currently USD 200, has a volatility of 30% and the prevailing risk-free rate is 2%.

(7 marks)

(c) Suppose that the stock price of a company Y is currently USD 250, has a volatility of 25% and the prevailing risk-free rate is 2.5%. What is the hedging position in the stock for an option writer who has sold an at-the-money 6-month call option 3 months ago?
