Nifty 50

The December Nifty futures closed at 20,375 on Friday, advancing 2.2 per cent for last week. The contract posted gain in all sessions over the past week.

As this happened, the cumulative Open Interest (OI) of Nifty futures ballooned till Thursday and saw a sharp fall on Friday – it shot up to 175 lakh contracts on November 30 versus 130.6 lakh contracts on November 24; it tumbled to 108.7 lakh contracts on December 1.

However, Nifty futures continued its upswing on Friday too. On a weekly basis, we can see considerable short covering, as the price went up and the OI declined. The chart of Nifty futures suggests potential for further rise this week.

On the options front, the Put Call Ratio (PCR) of the nearest weekly and monthly options stood at 1.2 and 1.4 respectively. Thus, a greater number of call options are being sold compared with put options, a bullish indication.

According to the option chain, the price region between 20,000 and 20,200 is a support band as cumulatively, the put options with these strikes have considerable OI. On the other hand, 20400- and 21000-strike calls have the highest OI. So, these are potential resistance levels.

The above factors denote a positive outlook. So, traders can consider bullish strategies. Consider longs on Nifty futures or alternatively, one can go long on at-the-money (ATM) December monthly call options.

As per the weekly option chain, 44,800 and 44,500 are the possible supports since put options with these strikes have highest OI. On the other hand, 45000-call have significant OI and so, this is a potential resistance. Subsequent resistance can be 46,000.
