'World markets suffered massive losses Monday, striking four-year lows, as panic-stricken investors doubted whether a Wall Street bailout package would stem the global financial crisis. London, Frankfurt and Paris all tumbled more than six percent approaching the half-way mark while a 15-percent dive in Moscow forced a halt to Russian trading. "We have a seriously weak and fear driven market at our hands," said Tom Hougaard, chief market strategist at City Index. "It is anyone's guess where we will end the day." Investors dumped shares after US stock markets had fallen sharply on Friday, despite US congressional approval of a 700-billion-dollar bank bailout.'
