Nov. 4, 2009 (The Hindu Business Line) --

Among the options, calls such as 4,700 and 4,800 shed open position, while 4,600 and 4,500 put witnessed heavy accumulation. The surge in 4,600 open interest indicates that it could act as a strong support for Nifty.
Stock futures

Heavy short covering was seen in most individual stock futures. Unitech witnessed a fall of 50.94 lakh shares in open interest while Reliance shed 7.11 lakh shares. However, it was Suzlon’s whose open interest tumbled to 90.51 lakh shares amid falling share prices. This indicates that traders are getting out of the counter as it failed to recover in line with broad market trend.

The other counter that witnessed a fall in open position included ICICI Bank (NYSE:IBN) , DLF, Bharti Airtel and JP Associates.
