Question 1 (18 marks) A trader at a local investment bank is reviewing the current global macro environment. She has taken note of rising natural gas prices in Europe, China's energy crunch, which has boosted the price of coal and led to recent high's in brent crude oil. While she is of the view that higher energy prices will likely be a temporary phenomenon, the immediate effect will be higher market volatility particularly for the energy sector. She believes that she can take advantage of her view on greater energy price volatility via Sasol (SOL) using an option strategy. Sasol is currently priced R232.42 and currently has suspended its dividend payments. She estimates Sasol's daily volatility to be 2.18% and notes that the current risk-free rate is 5.44% per annum. She wishes to hold this trade for 3-months. a) If the trader anticipates greater volatility, what option strategy would you recommend? Briefly justify your answer. (4 marks) b) Using the Black-Scholes option valuation model, calculate the value of the options that the trader will use to implement her strategy.
