The NSE Nifty 50 Index declined 1.2 percent on Thursday, its biggest fall since the global selloff triggered by the Brexit vote in June. While the index dropped, its August futures saw an addition of 3.8 percent in open interest, indicating a build-up of fresh short positions.
The Nifty Bank Index saw long positions unwind as the gauge declined 1.6 percent, along with a fall of 3 percent in total open interest.
More Index Puts for FIIs
Foreign Institutional Investors (FIIs) and proprietary desks together bought 41,756 index put contracts and unwound 7,882 index call contracts on net basis. This indicates near-term bearishness on part of the FIIs even though they continue to buy in the cash market and hold nearly 7 long positions in index futures for 1 short position held.
