Option Strategist Exercise 4: Option Trading Strategies
Using the CME Strategy Guide
Trading options involves taking a view of both the direction of the underlying and the magnitude of the volatility of the underlying. In this exercise we will set up positions, using the CME guide, to take advantage of expected changes in these two market variables. This will give you practice in changing existing exposures by buying and selling other options:
Underlying: GBP/USD
Price quoted in USD
Contract size: £1,000
European Option
Options on cash
One tick = 1/10,000 of quoted price
Value of one tick = 0.1 USD
USD Year basis = 360 days
GBP Year basis = 365 days
For all of the following positions use 1000 contracts (£1,000,000) per leg of the spread and 30 day maturities
• You are bullish and you believe that volatility is rising so you buy a 1.69 strike call option on Cable
Cable spot rate 1.69
Volatility 20%
US Interest Rates 5%
UK Interest Rates 5%
For all of the following follow-up strategies use the CME Strategy guide. For each new position you should be noting down the delta, gamma, theta and vega exposures.
• You are still a buyer of volatility but have turned bearish on the market.
