The Bombay Stock Exchange benchmark Sensex tumbled over 626 points at mid-session on Tuesday after the most-weighted stock on the index, Reliance Industries, touched a 52-week low for a brief while.
The 30-share index dropped by 626.24 points to 16,318.39 at 1300 hrs, as stocks of Reliance Industries, which has over 13 per cent weightage, crashed by Rs 204.45 to Rs 840.55.
Likewise, the wide-based National Stock Exchange index Nifty cracked the 5,000-points level to trade at 4,986.45, taking a hefty loss of 99.85.
Marketmen said the rude jolt to the market came in after someone off-loaded Reliance Industries stocks at an unbelievable level of 840.50 from yesterday’s close of 1045.05.
The steep fall was backed by a weak Asian trend and lower opening in Europe, they said.
