In yesterday’s session, a significant amount of Put Writing was done on 17800 and 17900 strikes to the tune of 3.5 million shares and 3.4 million shares respectively. On an EOD basis, the strikes of 17800 has maximum PUT OI of 5.8 million. This means that this point is likely to act as support for Thursday. There are brighter chances of this point being defended; however, Nifty’s behavior vis-a-vis the levels of 17800 will be crucial to watch. On the upside, 18000 levels hold maximum Call OI.
Coming to Bank Nifty, it has room to get a bit more weak as compared to Nifty after a strong relative outperformance over the past few days. The strikes of 38000 hold maximum Call OI which was obviously to act as a strong resistance in the event of any upside. However, due to a gap-down opening, we would like to focus more today on the 37000 strikes which hold the highest PUT OI. This point is likely to act as support in the event of any weakness and this point is expected to stay defended unless convincingly violated.
