The financial world is under different stress, caused by the evolutions of many relevant economic and financial indicators. The stock market provides us a direct and updated reaction of investors to the evolution of the global economy. The analysis of different indicators can show us a relevant correlation between stock indexes. The purpose of our paper is to see the relation between stock indexes and indexes that track the Worldwide shipping prices, or the relation with measures of implied volatility, between 2005 and 2010.
