CNBC-TV18's Head-Markets Research, Anuj Singhal has given F&O highlights: The volumes are much higher compared to last few days as the spotlight has again shifted to the Nifty. Nifty has seen big buildup both in the futures and on the options side. The Nifty OI PCR surged to 1.28 and that’s primarily because the 4,700 Put has added a staggering 13-lakh shares in OI - that’s quite a bit of buildup that we have seen at around that level.

The turnover is about 30% higher than what one normally sees at this time. It is about Rs 24,000 crore and more importantly the Nifty average by about 2:30 pm has been about Rs 10,000 crore and it is already much above that. The Nifty turnover is close to about Rs 12,000 crore with a 7 points premium and 35 lakh shares OI buildup. So definitely a lot of interest in the Nifty as we see Nifty trading above the 4,800 level.

Only a few stocks have seen some sort of OI buildup like SAIL, which has seen a buildup of about 8 lakh shares in OI. Cairn is one stock, which has extended its gains with a buildup of 5 lakh shares - that’s nearly 10% buildup. It has been a good week for Cairn, which is up Rs 8 in today's trade as well.

BILT is having some sort of relief run over the last two-days. It has seen a fresh buildup of nearly 3 lakh shares.
