The Nifty Index ended with gains of nearly one percent at 6000.65 marks. On the derivatives front we have seen that the Nifty Futures prices surged along with a nominal rise in the cost of carry and addition of open interest this is an indication of some longs being built in it at lower levels. On the options front we have seen that the OI PCR has increased to 1.32 vs. 1.25 mainly on account of addition of open interest on put options front and shredding of open interest on the calls front at strike price of 6000. The Indian Volatility Index has shown a decline of nearly 5%, indicating that the volatility has eased off due to buying support being seen at lower levels.
