Nifty 50 (18,534) ended last week with a minor gain of 0.2 per cent, whereas Nifty Bank (43,938) was down 0.2 per cent. We could observe some short covering in Nifty 50 and mild long build-up in Nifty Bank futures over the past week. Below is an analysis of futures and options (F&O) data of both indices.

Nifty 50

The Nifty 50 June futures closed at 18,636 last week, producing a gain of 0.3 per cent. But the cumulative Open Interest (OI) of Nifty futures dropped slightly to 100.6 lakh contracts on June 2 as against 102.4 lakh contracts on May 26. An increase in price along with a reduction in OI shows short covering on Nifty futures.

Coming to options, the Put Call Ratio (PCR) of the nearest weekly expiry stands at 0.74, as there has been a greater number of call writing compared with put selling. This is a bearish sign. However, the PCR of June monthly options contract is at 1.38, indicating more put writing. So, although the outlook for this week may be a bit bearish, participants expect the index to recover towards the end of this month.

For this week, 18,500 and 18,600 are the key support and resistance levels respectively as suggested by the options chain. Overall bullish bias will remain valid so long as the underlying index stays above the support at 18,500.

From a trading perspective, one can stay on the fence for now and initiate long positions when the Nifty 50 crosses over 18,600.
