The Nifty ended the day at 4,809 and Sensex shut shop at 16,017

It was a rough session today on Dalal Street with weak global cues weighing heavily on markets. News of Spain's central bank taking control of a belaguered small savings outfit served as a reminder of the financial uncertainty in Europe. Also, rising geopolitical tensions between North and South Korea added to the negative sentiment.

Asia and Europe too were a sea of red today. The Nifty ended the day at 4,809, down 137 points, while the Sensex shut shop at 16,017, down 451 points.
