The BSE benchmark Sensex on Friday rose to a nine-week high of 19,131.70 but later tripped by more than 220 points as investors sold bluechips, especially metal and mining stocks, on worries that new mining draft would hurt corporate earnings besides a likely cabinet shuffle next week.

The Bombay Stock Exchange benchmark Sensex, which had gained 350 points in the previous session, closed down 220.26 points at 18,858.04 as metal, refinery and banking stocks suffered heavy losses in volatile trading.
