You may track option prices through a variety of Internet sources. Go to the CBOE home page (www.cboe.com) and select an index option based on the S&P 500 and the Russell 1000. Select a call and a put option with the same expiration dates and a strike price close to the current value of each index. Track the prices of the options and each index for a period of two to four weeks. What were the percentage changes in the indexes and in the put and call options?
