CNBC-TV18's research analyst, Anichya Shah has given F&O highlights: More and more F&O stocks are participating in today’s rally which is why we are seeing Nifty’s contribution come down from about 51%-52% in the morning to about 46%. What remains the concern is that your total turn over volume still remained pretty low, only at about Rs 17,000 crore.

If you look at the Nifty, what’s very interesting is that the 4700 put has added a fair bit of open interest and there has been huge unwinding at the 5,000 call level which we saw a fair bit of call writing in the last few months, in the Nifty we are seeing some bit of long build up early in the morning that coupled with a bit of short covering has left the Nifty at about a 17 point premium, but we are seeing some sporadic bits of profit booking which is why you are not seeing a huge change in the open interest overall.

Nifty Mini which is pretty representative of the trend that’s happened today, accounts to about 2%-3% of the total turn over, you can see its been driven by a fair bit of short covering, it shed about 1.3 lakh shares and the premium is actually about 10-11 points right now, so a fair bit of short covering in traders initiated positions in mini Nifty.

SAIL has stood out in today’s session, good amount of long build up, 15 lakh shares have been added here and it has inched to a premium especially in the last half hour or so, so this stock is extremely looking from the last year’s space. Hindustan Unilever another stock from the last year's space which has seen some good open interest build up, 5.9 lakh shares, it hasn’t gone into a significant premium but it is seeing pretty aggressive additions of long as we speak and even the power space, whether if it is JP Hydro or Power Grid, we are seeing a fair bit of open interest build up, both these stocks have ventured into a fair bit of a premium and you can see JP Hydro has added about 5.4 lakh shares and IT which will be a space of interest in this week has seen some bit of long build up namely in Satyam Computer which has added about 3.2 lakh shares inching into a bit of a premium as we speak and as I said more and more stocks are participating in this rally.
