Nifty 50 trading strategy for expiry day
The high open interest concentration in Nifty on 5th August 2021 expiry is at 16300 Call and 16200 Put is indicating range bound movement on Thursday and to take advantage of the same we are suggesting a strategy called SHORT STRADDLE. This strategy involves selling of (ATM) CALL & PUT one lot each of 16,250 strike having premium of 46 and 44 respectively garnering in total inflow of Rs. 4,500 (90 points). As it’s a credit spread from profit perspective this strategy will generate maximum profit of Rs 4,500 restricted to total premium received if Nifty closes exactly at the sold strike i.e 16,250 on expiry; however, incase if Nifty breaches the upper breakeven level of 16,340 or the lower breakeven level of 16,160 then the loss can be virtually unlimited and hence it’s advisable to maintain a combine premium (i.e add premium of call + put together) stop loss of 130-140 points so that if due to any reason if there wide movement in Nifty the exposure of unlimited loss can be curtailed.
The strategy will generate profits if Nifty remains in the range of 16,150 to 16,350 till the expiry and also closes between the same as the THETA or TIME DECAY of options will work doubly in our favour eventually making it a best-case scenario as we reach closer to expiry day on each passing hour.
