Abstract

This study adopts derivative pricing as an indicator of market expectations, with those results suggesting that general investors can use market expectations to predict the final settlement value of underlying assets. Most investment textbooks note that one of the major functions of futures is price discovery. Similarly, the implied volatility associated with option prices can be used to discover the volatility of the underlying asset. This study combines futures price and implied volatility to establish a probability space of market expectations regarding the final settlement value of the underlying asset, and verifies this probability space using empirical data from the Taiwan stock market. The verification results suggest that market expectations closely reflect the actual behavior of the final settlement value of the underlying asset, and thus provide a practical perspective on future price behavior. According to this study, investors can easily estimate underlying asset behavior based on the behavior of the related futures and options and without incurring significant measurement error, which can be helpful in risk management and planning investment strategies. Keywords: forecasting, market expectation, implied volatility, futures, probability space. 1 Introduction Most financial texts confer that the futures markets aggregate diverse information and expectations regarding the future prices of underlying assets, and thus provide a common reference price which is known as the price
