History of Option MarketHistory of Option Market
• Apr. 1973 CBOE– First Option Traded
• 1983 CBOE– First Index Option Traded
• 1986 Stockholm Stock Exchange– OMX Index Traded
Index options give market participants the ability to participate in anticipated market movements, without having to buy or sell a large number of securities, and they permit portfolio managers to limit downside risk (Ackert & Tian, 1999)

VolatilityVolatility
• The relative rate at which the price of a security moves up and down
• A Measure of Risk
![Page 11: OMX Index Option Efficiency Test Empirical test of market efficiency of OMX options Supervisor : Professor Lennart Flood Authors : Aijun Hou Aránzazu Muñoz.](https://reader037.fdocuments.net/reader037/viewer/2022103004/55190f345503462f428b483d/html5/thumbnails/11.jpg)
Volatility Forecasting MethodsVolatility Forecasting Methods
– Historical Volatility (HSD)• Annualized Moving Average of Daily Return
– WISD (Weight Implied Volatility)• Get Implied Volatility (IV) from the Market Price • Weight Average IV according to its sensitivity
towards price changing

• Options more traded = More Market information
• To adjust options’ sensitivities to the volatility
– High price sensitivity options to σ should be given more weight

• WISD is in general higher than HSD• When the underlying asset market is getting extremely
volatile, the derivative market tends to moderate it.
