CNBC-TV18’s research analyst, Anichya Shah has given F&O highlights.

It was an iffy sort of day of trade closing close to 4,700 levels, which is a very critical support. What made it a more iffy was the fact that we saw whole lot of open interest addition on the call side 4,700-4,800 and 5,000 level. 4,500 put which acted as a major support level in all the downturns we been seen over the last few weeks has seen a fair bit of unwinding in today’s trading session. We have seen some bit of short build-up in Nifty; yesterday was a fair bit of short rollovers but today throughout a day we have seen some bit of short build-up. In Nifty April future there was a bit of profit booking for the shorts at the end and that’s why open interest remained at 35 lakh but it did go into about 19 point discounts.

A lot of these stocks which saw long build-up over the last few trading session, lot of the momentum stocks like Chambal Fertilisers saw a fair bit of long unwinding today; it shed about 1.3 lakh shares and was down in the spot market.

SAIL has seem fresh short build up again 19 lakh shares have been added and this stock has been seeing fair bit of short build up over the last few trading session.

Power Grid from the power space saw significant short build up in today’s trade; added 13 lakh and it did go into a fair bit of discount. But JP Hydro another power stock that bugged the negative trend saw fair bit of long build up was up about 4%; 6 lakh was the open interest build up and the cost of carry is gone into about 0.5-0.6% premium.

Yes Bank ahead of its results saw fair bit of action especially post-non; up about 12% by day and good open interest build-up of about 3.5 lakh shares and the cost of carry was pretty strong at about 1.5%. So this could be one stock to watch out for going forward.
