CNBC-TV18's research analyst, Anichya Shah has given F&O highlights:

It was a good day in the F&O space but the turnover continued to remain slightly muted at about Rs 40,000 crore. We are going into expiry week and we do have a pretty long weekend, so as expected market wide rollovers were not too significant by end at about 15-16% considering we have this very long week in store. But what we did see is a fair bit of action on the option front. A fair bit of 5,100 calls and 5,200 calls got written and that seems to be a range that traders are playing for resistance on the upside as well as the long weekend would give a significant time gain on the options front.

On the Nifty what we saw was that rollovers did pickup in the Nifty. It came to about 30% market wide and some semblance of long rollovers. One can see the next month is at a slight premium but not a whole lot or not significant pressure. We should see that picking up on Monday or Tuesday next week, giving us a clear cue of the market direction.

SAIL, which has seen a huge short buildup in the last few weeks, down about 30% over the last one-month - today was driven up by a fair bit of a short squeeze. One can see it shed about 13.4 lakh shares - net it is actually shedding OI, so there is a clear short squeeze and it was up a fair bit in the spot market at about 4%.

The banking space looked pretty strong. The strongest stock in terms of rollovers from the banking space - IOB, which rolled close to about 52% of its positions with a good net addition of about close to 5 lakh shares. From the larger private banking space we saw ICICI Bank see its rollovers pickup about 16% there with a net addition of about 12 lakh shares and it did inch into some bit of a premium. This stock is usually flat, slightly negative, so that premium is a pretty positive sign.

HDIL from the real estate space has started buzzing in the latter half of the day. It saw good OI buildup with 6.2 lakh shares added but rollovers still have to pickup on this stock but it was holding a pretty strong CoC both in the April and May series even DLF looked strong in the F&O space.

Chambal Fertilisers was clearly the stock of the day in the F&O space. The stock was up about 20% with a huge OI buildup - net buildup of about 11 lakh shares primarily in the April series, so may see some bit of profit booking since the series will close in about four trading sessions and both the April and May series did inch into a premium.
