Crude $102 and 2.86 lakh shorts

Down 335 points from Friday's close. 4% gap down. Opened at 23,900 today morning and has already slipped to an intraday low of 23,735. This is crude shock repricing. Now here's where it gets interesting. Let me walk you through Friday's positioning because that's what's going to drive today's action at open. Pro traders were flat. They had just 91 contracts. Basically neutral on the futures side. They were holding long puts and long calls. Both are hedged. Pro isn't making a directional bet. FIs on Friday added 58,000 short contracts in futures in a single session.

That took their net position to 2,86,000 short. The highest short position we have seen in recent times. Not even during the March lows were they this short. But here's the paradox. The same FIs were net cash buyers at 672 crores on Friday. First time in weeks they have bought in the cash market. They bought puts, long puts around 3,30,000 contracts. Sold calls around 1,78,000 contracts. This isn't panic selling. This is a full institutional hedge book. Short the index as an overlay, buy equities underneath.

It's a collar strategy. 5% this morning and GIFT Nifty down 335 points, those short futures are printing beautifully this morning for FIs. The question is: do they take profits today and cover, or hold through the holiday tomorrow? Clients were max bullish on Friday. They had 1,43,000 long futures. Short 4,89,000 puts. They were selling insurance to FIs. Along with that, 1,26,000 long calls. All of that is underwater this morning. When the crowd goes all in and gets hit with a crude shock, that's forced unwinding in the first hour of trade.

Now the GEX picture. The gamma flip zone is sitting right around 24,000, exactly where Nifty closed on Friday. With GIFT Nifty at 23,750, we are opening about 300 points below the flip. That means we start the day in negative gamma territory. Market makers are short gamma. They amplify moves. Expect an aggressive volatile open. The 24,000 strike has massive 53 lakh total OI. Put OI alone stands at 67 lakh contracts. That's the gravitational magnet. Above 24,050 the GEX turns positive. 24,200 is your call wall with GEX at positive 2,776.

Those are the resistance zones. Not breaking those today. Straddle traded at 283. That gives us a 1 standard deviation range of roughly 23,650 on the bottom side and 24,350 on the upside. GIFT Nifty at 23,750 is within that 1SD range, barely. But if VIX spikes 10 to 15% on open, the realized range will widen. Key levels: 23,700 is the GEX support. Below that, moves accelerate. 24,000 is the expiry pin. 24,200 is the first resistance. Below 23,650 you've broken the 1SD floor, and that's real trouble.

08 on Friday. With this morning crude shock and gap down, IV is going to spike. This is day one of a fresh volatility event. Don't sell premiums at open. Let VIX settle. Let the first 30 to 35 minutes play out. If VIX starts cooling off that spike, then you sell. Sector wise, energy and metals have been leading. With crude breaking $100 again, energy names get a fresh tailwind. But double edged sword for India. IT was showing strength after TCS monster quarter.

But some TCS bad news is hitting the markets as well. Banking likely takes a hit in today's gap down. Watch if Bank Nifty holds 54,000. Today is also RupeeCase Nifty's rebalancing day. Every two weeks the strategy rescores all 50 stocks on momentum. Top 10 get equal weighted. No opinions. Pure data. If a stock's momentum fades, it exits. If a new name accelerates, it enters. A metal stock is entering. An IT stock is entering. Some pharma names are exiting. A systematic strategy doesn't wait.

It executes. My read for today: expiry day gap down into negative gamma with a crude shock catalyst. VIX will spike in the first 30 to 60 minutes. Could test 23,650 if panic sets in. But the massive OI at 24,000 acts as a magnet. I expect the market to find a low in the first one or two hours, then grind back toward 23,800 to 23,900 by close. 5 to 1% from Friday. But this is a buy on dips week. Today's dip is the entry.
