Abstract

The theory often sees options as financial instruments very similar to other derivatives in that sense that their value depends on prices o f other assets called underlying instruments. The feature that makes options different from other derivative instruments is that their value also depends on volatility of market prices. In fact speculation on prices, which is a dominating use of let’s say futures, makes up only a small margin of options trading. It is the speculation on volatility, that stands behind the bulk of transactions with the use of options. As a result the risk of an option is mainly a volatility risk, which needs to be measured by special tools. The need of creating a new category of market risk has aiso arisen as it is not possible to classify a volatility risk into one of the traditional four market risk factors which are: stock prices, interest rates, exchange rates and commodity prices.
