The BSE Sensex tanked 440 points to end at over three-month low of 31,159.81 due to across the board selling by investors ahead of the expiry of September derivatives and weakness in the rupee amid mixed global cues.
Extending its falling streak for the seventh straight session -- the longest losing streak since December 22 -- the 30-share index fell by 439.95 points, or 1.39%, to settle at 31,159.81 as RIL, HDFC, HDFC Bank, ITC, SBI and L&T dropped.
This is the weakest closing since June 30 when it had settled at 30,921.61.
The broader NSE Nifty cracked below the key 9,800-mark. It had regained the key 9,900-mark at the outset, but failed to hold on to the crucial level and dipped below the 9800-mark to hit a low of 9,714.40.
It finally settled down 135.75 points, or 1.38 per cent, at 9,735.75, it lowest closing since August 11 when it closed at 9,710.80.
The September futures and options contracts are set to expire tomorrow, which made participants wait and watch.
