Shrugging off its early gains, the benchmark Sensex on Thursday declined by over 81 points at 1115 hrs due to profit-booking at higher levels.
The BSE-Sensex opened higher by over 80 points to 11,367.23 on good support from foreign funds on the back of higher global cues, but declined to 11,203.10 at 1115 hrs, a fall of 81.63 points over the previous close.
Marketmen said profit-taking by funds at existing higher levels led to the decline in the equity markets.

The National Stock Exchange's 50-share Nifty also moved down by 23.60 points to 3,460.55 from its previous close.
