The country's official jobs data, which showed that nonfarm payrolls increased by 171,000 in October beating estimates, raised concerns that the Federal Reserve may abstain from further monetary easing measures.
China's leadership change is also set to take place this week. Although there is no uncertainty over the leadership, investors are waiting to know the new regime's policy decisions.
Markets reacted negatively even after official data showed that the country's service sector purchasing managers index (PMI) had increased to 55.5 in October from 53.7 the previous month. China's manufacturing PMI, released in the previous week had also shown improvement.
News from the eurozone too remained discouraging. Reports suggested that Greece's public and private sector workers plan to go on a strike against the government's proposed austerity measures. The country has to reach a consensus on the issue to secure the much needed bailout package from international lenders.
