||Option price analyzis gives us an insight into the expectations of investors in the financial markest. More precicely, the put-call parity and distribution implicit in option prices gives us information about whether the investors expect downturn or upswing on financial markets. Hence the main goal of our project is to explain the reactions of world-wide option markets on financial turmoils. We will use actual cross-sectional option prices datasets covering the period of last major financial crisis in year 2008 to empirically test our hypothesis. Our next goal is to analyse the expectations of financial markets participants during the post-crisis period, again on up-to-date year 2009 option datasets.
