Derivative Market Update: Last week, Nifty March futures ended with a loss of 0.9 per cent at 22,444. The contract closed at 47 points premium as against the spot Nifty at 22,397. The open interest (OI) in the March contract dropped by 2.7 per cent. In Nifty options, the 22,200 – 22,500 region has seen significant accumulation of both CALLS and PUTS, setting the stage for a classic tug-of-war scenario, says Dhupesh Dhameja, Derivatives Analyst of SAMCO Securities. PUT writers continue to increase exposure at lower levels, reinforcing a strong demand zone. The Put-Call Ratio (PCR) dipped from 0.86 to 0.70, reflecting a slight bearish tilt as traders added short positions. The Max Pain level at 22,400 suggests that bulls are attempting to absorb selling pressure, preventing a sharp directional move, the analyst added. Meanwhile, the Bank Nifty March futures slipped 1.1 per cent to 48,160, on the back of 6.1 per cent increase in OI. Similarly, the MidCap Nifty futures shed 2.9 per cent along side a 2.9 per cent rise in OI. In the case of Bank Nifty, a decisive breakout above 48,500 is essential to trigger a sustained rally. As long as the index sustains above 47,800, buying on dips remains a favourable strategy, with 48,500 serving as the key breakout level, said Dhupesh Dhameja.
