The Tanmay Edge | India's pre-market edge, every trading day.

Eight episodes ago this podcast put one sentence on record: if oil crosses 90 dollars, the support under this market starts breaking. Overnight, Brent crossed it, 91.16 at recording time, and it picked expiry morning to do it. The same file shows retail walking into today short 6.61 lakh puts, naked, their THIRD consecutive record after 5.74 and 6.08, having sold 53 thousand more into Monday's fall, one night before the trigger fired. And expiry implied volatility, asleep at 7.8 percent on Friday, woke 25 percent overnight to 9.7. It is expiry day: something resolves at 3:30, by force.

Monday itself was the fifth straight lower close, a staircase: 24,472, 24,436, 24,396, 24,366, 24,287.65, roughly 45 points a step, with the seventh sector rotation in seven sessions, IT hammered while realty and metals rose. The war behind it reached maximum size: foreign institutions sold 2,535 crore of cash, their biggest of the month, pushed 8,423 crore through index options in a single day, and hold a fresh cycle high 1.82 lakh index futures short with a put book through 5 lakh contracts for the first time. Domestic funds wrote their second 5,000 crore cheque in three sessions. The proprietary desks doubled their long put leg and hold long volatility on both sides, a book the overnight spike already pays. Nobody informed is short volatility this morning. Only the crowd is, in record size, for the third time.

Today's board is a genuine battleground, all from the official file. Max pain sits at 24,350, sixty two points ABOVE spot for once, with the expiry future sixty points over. The put writers mounted the biggest single-strike defense of the cycle right under the market: 135 lakh puts at 24,300, 83 lakh at 24,250 after Monday's biggest single add, 104 lakh at 24,200, a 114 lakh base at 24,000, 108 lakh contracts of defense raised between 24,200 and 24,300 in one session. Above, 71 lakh fresh calls at 24,350 and 105 lakh at 24,400. The straddle costs about 125. The gamma map splits the day: negative below 24,350 where moves amplify, positive above 24,400 where they damp, and the open lands inside the pit.

The two arguments, both on the table: the pin, if oil cools, with the magnet overhead and an enormous put army below; or the break, if oil holds above 91 and 24,250 gives way, where the crowd's record naked puts become the fuel toward 24,000. The episode does not pre-choose: the level chooses. The firm calls: do not sell today's volatility, own movement small and defined after a stop day, and be flat of expiry premium by 3:15, because the closing auction owns the last print of every session now.

Episode 104 graded 3 on 5, straight: the buy-dips bias was wrong and the stop at 24,300 fired by twelve points, but the do-not-sell-vol rule paid in full overnight. Also inside: the rupee at a new weakest 95.61, US yields at 4.73, Korea's melt-up against a red Asia, and the AllCap's fresh rebalance cycle opening with 0.40 percent of alpha on day one.

Five days ago the crowd's record short put book burned in a two hundred point flush at 24,266. On Friday they rebuilt it, bigger: retail is now short 6.08 lakh puts, naked, a new record for this cycle, sold at the cheapest premium of the month, one trading day before Tuesday's expiry. On the other side, the proprietary desks bought their volatility book back on BOTH legs, 1.37 lakh calls and 0.60 lakh puts, at 7.8 percent front week implied, the floor of the entire three week arc: ten, twelve point two, nine nine five, nine four four, eight five three, and now seven eight. Every floor in that sequence preceded a violent week. The one day straddle for Tuesday costs about 168 rupees, the cheapest movement has been priced this cycle.

The foreign institutions run maximum insurance while still buying: put book at a fresh high of 4.97 lakh, index futures short at a cycle high 1.77 lakh, short 2.77 lakh calls, and yet 508 crore of cash BOUGHT on Friday, their second purchase in three days, with 5,589 crore pushed into index options in one session. Buying the stock, buying the protection, selling the futures: the same hedged accumulation fingerprint, four weeks running, bigger each week.

The board is building a textbook pin. Max pain holds at 24,400 for a fourth straight session, and last week taught the lesson: a sliding magnet chases price, a stable magnet holds it. Friday's flows pulled everything inward: 24 lakh fresh puts at 24,300, 18 lakh more at the 24,000 base now 114 lakh strong and the heaviest support on the board, 11 lakh calls added right at the money, and 15 lakh far calls covered at 25,000. Resistance sits at 24,400 then 24,500 with 113 lakh calls.

Also today: rebalance day. The AllCap rotated its book this morning after a cycle in which the alpha widened five days in a row, 0.59 to 1.26 percent, while the benchmark fell one and a half percent through six sector leaderships in six sessions. The fresh scorecard: net 607.66 percent since inception against 49.02 for the benchmark, alpha of 558 points, CAGR 47.88, fifty fresh names at two percent each. Churn is the enemy of conviction and the food of systems.

The plan, and the bias has not changed all month: buy on dips. Dips toward 24,300 are for buying, with a close below 24,300 as the stop, because under that level the crowd's record naked puts become the fuel toward 24,000. Reclaim 24,400 on a close and the 24,500 fight opens. And rule one, for the third Monday running: do not sell volatility at 7.8 percent into an expiry the crowd has already sold in record size. Own a little movement, keep it small, and be flat of expiry premium by 3:15 tomorrow, because the closing auction now writes the last print of every single day, not just expiries.

Episode 103 graded 4.5 on 5: the pin-drift around the stable magnet printed exactly as mapped.

Between 3:15 and 3:26 on Thursday the Sensex did absolutely nothing. The equilibrium price sat frozen near 77,890 and the expiry straddle, 425 rupees at the open, melted to about 80. Then, in the final four minutes, the closing auction moved almost three hundred points: the indicative price went from 77,859 at 3:22 to 78,143 at 3:26, and the settlement printed at 78,079.96, up 113 on the day and 80 points over the 78,000 battleground. Round three of the closing auction answered episode 102's question with cruel precision: the pre-paid fireworks came, one minute too late for anyone still holding premium. Even a 78,000 straddle bought for 80 in the window settled worth about 80, breakeven on a 284 point swing. The new rule that completes the auction playbook: the move now lives after 3:26, inside the uncross itself, where nobody trades. A frozen equilibrium and a melting straddle are not safety, and you cannot buy the auction move with listed premium. The old rules stand taller than ever: never trade the indicative print, and be flat into the window.

The quieter headline: for the first time in two weeks, BOTH magnets worked. The Sensex settled 80 over its max pain and the Nifty closed at 24,395.85, four points from its 24,400 max pain, after dipping to 24,311 and being pulled back by its own closing session. The lesson: max pain works when it stops moving. The Nifty's magnet slid 24,600 to 24,500 to 24,400 all week and price fell with it; the moment it stabilised, it pinned.

Positioning turned heavy-handed. The proprietary desks sold 63 thousand puts, flipping their put book short: selling floor insurance at 8.5 percent implied, the cheapest volatility of the entire two week arc (10, 12.2, 9.95, 9.44, 8.53). The crowd covered 89 thousand of its record naked put book, down to 4.86 lakh, and bought calls. The foreign institutions built their heaviest book of the cycle: short 2.89 lakh calls and 1.69 lakh index futures, both cycle highs, long 4.74 lakh puts, with 13,538 crore pushed through index options in one day, while selling 511 crore of cash into domestic funds' 4,353 crore absorb, the second big local cheque in three days.

The new week's board is a ladder: resistance every hundred points from 24,500 (105 lakh calls) to a monster 24,800 (108 lakh after the day's biggest add) and 25,000 (131 lakh); support every hundred from 24,300 (78 lakh puts) to the 24,000 base (96 lakh). The weekly straddle costs about 205 at the cycle's cheapest volatility. Also inside: the fifth sector rotation in five sessions with defensives leading, Korea's four day melt-up, US yields breaking lower, oil deflating from the 90 trigger, the rupee at its weakest close, and the RupeeCase AllCap book whose alpha has widened five straight days to 1.26 percent, with the rebalance due Monday. Episode 102 graded 4.5 on 5: the pin came, the straddle sellers ate, and 77,500 held with 166 points to spare.

At noon on Wednesday the Nifty sat at 24,266, down two hundred points, deep in the exact air pocket episode 101 mapped. Then somebody wrote a 5,842 crore cheque at the bottom. Domestic funds made their biggest single day purchase of the month, straight into a falling knife, on the same day foreign institutions sold 1,002 crore of cash and added to index futures shorts now at 1.65 lakh contracts. The V that followed recovered 170 points into a 24,435 close, down just 36. The open at 24,472 was the high of the day, the third straight session where the best print came in the first minutes.

The options board delivered three lessons. One, max pain has slid three days in a row, 24,600 to 24,500 to 24,400: a falling max pain is a trend follower, not a floor, the magnet chases price rather than pulling it. Two, call writers are chasing too, 42 lakh fresh calls sold at the money at 24,400 and the 24,500 lid now at 89 lakh contracts, while 24,500 put writers covered 12 lakh and left. Three, the proprietary desks that dumped their entire long volatility book into Tuesday's expiry at 12 percent implied bought it back on Wednesday at 9.4. One day later. Buy volatility when it is boring, sell it when it is terrifying, and repeat: that loop has now run twice in seven sessions and is the best tell on the board.

And the crowd re-sold the insurance one day after it burned: another 51 thousand naked puts into the V, taking the short put book to 5.74 lakh contracts, a new record above last week's peak, plus 1.48 lakh long calls on top. Foreign institutions lifted their put book to 5 lakh, also a fresh high, against 6.24 lakh long stock futures.

Today's main event: the Sensex weekly expiry, round three of the new closing auction. Round one misfired with phantom prints. Round two settled clean while the indicative price went wild inside the window. Both times the market walked in unprepared. Not today: Sensex one day implied volatility sits at 13.5 percent, up 19 percent, against 9.4 on the Nifty, four full vol points of auction premium, finally priced. Round three asks the opposite question: when everyone has paid for the fireworks, do they come? The board: 78,000 the battleground with 16 lakh calls against 11 lakh puts and max pain there, the floor at 77,500, the straddle near 425. The rules stand: the indicative print is not the close, nothing market on close, and theta collects all day before the window pays.

Also inside: the fourth sector rotation in four days with PSU banks up 2 percent while TCS fell 3.7, Korea's two day 7 percent melt-up, gold living at a record 4,424 dollars, Brent stalled at 88.8 with the 90 dollar trigger still loaded, and the RupeeCase AllCap book green on a red day with alpha of 0.99 percent since rebalance. Episode 101 graded 4 on 5: the fail branch ran from the opening bell.

The map: Nifty boxed between the 24,400 magnet and the 24,500 lid, 24,600 above on a reclaim, and below 24,300 the crowd's record naked puts are the fuel toward the 24,000 base. Keep risk defined and small, and give the auction its respect.

The 100th episode's exam had a trick question in it. We mapped a 24,500 to 24,600 box and the market tore the floor off it in the first thirty minutes: the open at 24,575 was the high of the day, 24,500 broke by 9:45, and the Nifty fell into the air pocket to 24,429 before closing at 24,471, down 112 points. The Sensex lost 388 at 78,154. And the weekly expiry settled 128 points BELOW max pain. Today's first lesson: max pain is a tendency, not a law, the second failure in three expiries.

The grade, given straight: the buy on dips bias was wrong, a stop loss day. What survived was the process. The 1 by 2 call spread lost only its 34 point ticket, about 2,200 rupees a set, exactly as designed. The oil conditional said word for word that oil rallying toward 90 dollars could break 24,500, and Brent went from 87.90 to nearly 89 as the floor gave way. And scenario three, break below 24,500, naked puts burn, air to 24,400, described the day to the point, low 24,429. Three on five. When you are wrong, the exit is the trade.

Then the beautiful part: a complete volatility cycle in three sessions. Friday, front week implied under 10 percent, and this podcast said do not sell it. Monday, IV exploded 22 percent to 12.2 and the curve inverted. Tuesday, crushed back to 9.95, VIX down to 11.8. And the proprietary desks, from the official participant file, dumped their ENTIRE long volatility book into the expiry, 2.14 lakh calls and 0.72 lakh puts on Monday reduced to nearly zero by Tuesday close. Buy vol when it is boring, sell it when it is terrifying, executed in plain sight.

Who bought what they sold? The crowd. On the breakdown day retail bought 2.09 lakh calls, going net long 1.89 lakh calls while still short 5.2 lakh puts: positioned maximum bullish in both directions at the lows. The foreigners went the other way again, put book at a fresh high of 4.85 lakh contracts, four to one hedged long via 6.17 lakh stock futures.

The new board for the 18 August week: max pain has moved down one floor to 24,500, and both armies rebuilt it in a day, 40 lakh fresh calls and 24 lakh fresh puts on that one strike. The deep put base sits at 24,000. The weekly straddle costs about 281 at a 9.95 implied, cheap again, Friday's setup one hundred points lower. Sectors went defensive: India Internet up 1.9 percent, pharma up 1 percent and IT green on a red day while cement and FMCG sold.

The Wednesday map: the whole day is 24,500. GIFT Nifty at 24,556 points to an open above it, so the reclaim test comes at the bell. Hold above on a close and the pin engine restarts toward 24,600. Fail, and rallies are for selling, 24,400 first, air to 24,200 below, with the crowd's short puts as fuel. Two riders: Brent at 89.38 is sixty cents from the 90 trigger, and tomorrow is the Sensex weekly expiry, the third run of the closing auction. Keep the risk defined. Tuesday showed why.

Plus the RupeeCase AllCap book: alpha of 1.01 percent since rebalance, widened every day of a falling week.

One hundred episodes. One hundred trading mornings of reading the actual exchange data, taking a view on record, and grading it in public the next day. And for the milestone, the market arranged a proper exam: a weekly expiry with the entire options board squeezed into one 100 point box.

The board, from official settlement data: 24,500 now holds a 112 lakh contract put fortress, 39 lakh added in a single session, the biggest wall on the board. 24,600 carries 146 lakh calls AND 109 lakh puts, both armies on the same strike, with max pain sitting there for the third straight day. On Monday put writers added 2 crore contracts against just 10 lakh fresh calls, lifting the put call ratio from 0.73 to 0.85. Above the box: 109 lakh calls at 24,700, 118 lakh at 24,900, 129 lakh at 25,000.

The special segment: a volatility masterclass in three clocks. Clock one, implied volatility. Friday the market priced this expiry at under 10 percent while the back weeks sat at 10.6, episode 99 said do not sell that volatility, and on Monday front week IV exploded 22 percent in one session to 12.2. The curve inverted: today now costs more than next month. Clock two, forward volatility, roughly 10.65 percent to next week and 11 percent to the monthly, so the fear is about today specifically. Clock three, the theta clock: the straddle closed near 146, should open around 120, melt another 30 to 40 rupees through the day toward 80 by 3:15, and then the last 15 minutes belong to the closing auction, where these two weeks have taught us the wildness now lives.

Positioning into it: proprietary desks long 2.14 lakh calls and 0.72 lakh puts, long volatility on both sides. Foreign institutions at a week high 4.30 lakh puts, hedged 4 to 1 long via 6.27 lakh stock futures, and on Monday the role reversal: FIIs bought 1,975 crore of cash, their biggest buy in weeks, plus 3,925 crore into index options, while DIIs sold 1,290 crore, their first sell after absorbing over 7,000 crore all week. The crowd is still short 5.53 lakh puts, naked, into expiry morning.

The plan on record: bias stays buy on dips with a close below 24,500 as the stop. On expiry day the tool is the call spread, not the naked option: buy 24,500 sell 24,650, or buy 24,550 sell 24,700, one by two or two by three, selling the strikes the wall writers own so their decay finances the position. Cut the extra leg if 24,700 breaks, be flat by 3:15, and never trade the indicative print in the auction.

Also inside: Monday's second rotation flip in two sessions (Titan +3.1%, Bajaj Finance +1.9% against SBIN -2.2%), VIX 12.33, Brent near 88 dollars after a 5 percent two day run, gold at a fresh record 4,426 dollars, and the milestone scorecard: the RupeeCase Nifty 50 strategy at 596.98 percent net since inception versus 49.58 for the benchmark, a 47.43 percent CAGR. Episode 99 graded 4 on 5: the 24,511 dip was bought to the point.

On Friday the Nifty did exactly what this podcast mapped: it broke 24,600, drifted, and stopped at the 24,500 shelf, low 24,522, close 24,570.65, down 0.27%. The Sensex fell 455 points to 78,499. The VIX sat at 12. But while the price did the boring thing, the options board did something violent, and that is today's episode.

The strike that was the market's strongest support on Thursday became its strongest resistance by Friday evening. At 24,600, put writers covered nearly 9 lakh contracts and call writers sold 64.5 lakh fresh calls, taking the strike to almost 1.2 crore contracts, the biggest wall on the entire board. The put defense retreated one floor down to 24,500, exactly where Friday's fall stopped. The put call ratio for Tuesday's expiry collapsed from 0.96 to 0.73. Max pain is still 24,600 and the spot closed 30 points below it. The magnet is now overhead.

Under the hood, the sharpest positioning split of the week. The proprietary desks flipped their put book from short 40,000 to long 1 lakh contracts, a 1.4 lakh swing in one day, while holding 2.4 lakh calls: a long volatility book walking into expiry. The foreign institutions hold 4.14 lakh puts and 2.13 lakh short calls against 6.34 lakh long stock futures, a 4 to 1 hedged long, and they bought 480 crore of cash equities on Friday, their first real buy of the week, with domestic funds adding 236 crore. The crowd sold another 1.68 lakh puts naked and is short 5.67 lakh into expiry eve at a 12 VIX. The pros are long movement, the foreigners are insured, the crowd sold everyone their crash protection.

And Monday morning leans one way: the Nikkei is up 2%, Taiwan up 2.1%, Hang Seng up 0.7%, Nasdaq closed Friday up 1.3%, Brent is at 84, gold sits just off its record at 4,327 dollars, and GIFT Nifty at 24,670 points the open straight at the 24,600 wall.

So today the podcast takes a side. The bias is buy on dips: flat breadth of 1,684 advances to 1,664 declines says Friday was rotation into IT and autos, not distribution, with Bajaj Finance down 5.9% against TCS up 3.5%. Dips toward 24,550 and 24,500 are for buying, the stop loss is a close below 24,500, because under that level the crowd's 5.67 lakh naked puts become the fuel. The trigger is 24,600 on a closing basis: above it the trapped call writers cover, 24,700 and 24,800 come fast, and the targets are 25,000, where 113 lakh calls are stacked, then 25,200. And rule one: with the Tuesday straddle at just 222 points and front week volatility near 10%, do not sell volatility, buy it. The crowd already sold. Plus the RupeeCase AllCap book: benchmark down 0.82% since rebalance, strategy up 0.02%, alpha 0.85% in a falling week.

Episode 98 called the break of 24,600 and the stop at the 24,500 shelf: graded 4 on 5. Full scorecard on rupeecase.com.

The Sensex closed up 373 points at 78,954, clean and orderly, and the settlement everyone feared would break under the new single closing auction held just fine. But in the last ninety seconds of the day the price on your terminal ran to a level the market never actually traded, and then it came back. That was the auction talking, and it is the whole story of episode 98.

The Nifty told the same lie the other way. It closed at 24,636, up eleven points, a 73 point range, the tightest day of the week, fifteen stocks up and thirty four down, the volatility gauge at 12. Dead on the surface, coiled underneath. Reliance was up 3.4 percent, State Bank up 3, Bharat Electronics up 2.5, ICICI up 2.3, while TCS fell 2 percent, Infosys slipped, autos and metals lost about a percent each. The index is a weighted average, the winners and losers were the same size, so the headline froze, and the smallcap index quietly finished up 1 percent on the same day.

This was the first Sensex weekly expiry run through the new closing auction, and after two misfires earlier in the week the market braced for another. The settlement did not break. The futures basis was barely a point off fair value. But the volatility did not vanish, it moved into the auction window itself, where the indicative price, the provisional number the exchange shows while it matches all the closing orders, spiked hard before snapping back to an orderly print. The lesson of the day: the indicative price is not the close, it is a work in progress that swings on thin, lumpy order flow, so do not trade it and do not fire a market on close order into an auction the market has not learned to trust yet.

Under the hood the positioning is a standoff. The Pros are leaning bullish, long about 1.91 lakh index calls and short 40,000 puts. The foreign institutions are the mirror image, long 3.88 lakh puts and short 1.63 lakh calls, carrying 1.45 lakh short index futures against a 6.4 lakh long stock book, a four to one hedged long, insurance and not a crash call. The crowd is short almost 4 lakh puts naked at a 12 VIX, paid almost nothing for the risk. Nobody is capitulating, which is the definition of a coil. Domestic funds carried the tape: FIIs were flat in cash at minus 18 crore, DIIs bought over 4,000 crore.

Into Tuesday's Nifty expiry, 24,600 is the magnet and max pain, the biggest stack of options for the week, with put writers piling in there and at 24,700, roughly 35 lakh and 28 lakh added, building support up. Call writers below 24,700 bought their calls back and rolled the lid up to 24,700 and 24,800. Support up, resistance up, quietly constructive. The straddle is about 252 points, gamma flips positive just above 24,650, and we closed a hair below it. GIFT Nifty near 24,646 points to a quiet open, the US closed a touch lower, Asia is red this morning, Brent is 83 dollars and gold sits near a record at 4,258. The map: 24,600 support, 24,700 the lid then 24,800, above 24,700 on a close the coil breaks, below 24,600 a drift to 24,500, otherwise a pin into Tuesday.

Here is a correction to the textbook, and it is the whole story of today. Yesterday the RBI held, repo unchanged at 5.25 percent, a neutral stance. Everyone will tell you that after a boring hold like that, volatility collapses, the classic IV crush. Look at your screen. It did not. The Sensex volatility is not falling, it is rising. The expiry straddle is staying fat and the vol gauge is popping. And there is a very specific reason: today is the first ever Sensex weekly expiry that settles under the new single auction close, the same auction that misfired twice on the Nifty this week. Nobody has ever seen this settlement. And when the market does not know how it is going to close, it does not sell insurance, it buys it. That is why the vol is going up, not down, into the one session it should be falling.

Let me make the risk concrete. The Sensex weekly options settle on the closing price, and from this week that close is a single auction print in one short window, not a thirty minute average. On the Nifty this week that window misfired twice, printing the index nearly 190 points away from where it traded. Now think about selling the 78,500 straddle today for a quiet pin: if the auction prints the Sensex a couple of hundred points away from where it traded all day, your short is settled against a number that never existed, and you are run over at the bell, by a print, not by the market. The desks know this, which is why they are bidding the vol, not selling it. The straddle that should bleed on the last day is staying rich because the settlement itself has become the risk.

This turns the usual expiry rule on its head. Normally volatility falls into an expiry, the pin and the decay of time crush the premium, and the smart trade is to sell the option. But that only holds when the settlement is predictable. The moment the way the market closes becomes uncertain, the settlement stops being a formality and becomes a fresh source of risk, and vol rises. When you cannot trust the close, you do not sell the close. You buy protection against it.

So the plan today is about how to trade, not where the levels are. Rule one: do not sell options into this close. Selling a straddle into a first ever Sensex auction expiry is picking up pennies in front of an unknown machine. Rule two: if you want a position, the safer side is to buy, not sell, owning a straddle or a cheap wing so an auction shock pays you instead of destroying you. Rule three, maybe the best: do not trade the last fifteen minutes at all. Stand aside from 3:14, let the auction happen and get absorbed, and come back tomorrow. There is no edge in guessing a print nobody has ever seen. On the Sensex the level near 78,600 sits above max pain at 78,500, but do not lean on that pin today, the auction can override it.

Underneath, the Nifty is the side show but still constructive. Yesterday the foreign funds added 63,594 short calls capping 24,600 to 24,700, but the pros bought 1,47,214 calls and the domestics bought nearly 2,900 crore of stock. Buy dips toward 24,500 with the 24,000 floor, and a clean break of the 24,700 wall still opens 25,200, but trade that in the morning, not at the bell. Overnight the global lead is soft, US tech slipped and Asia is red, yet GIFT Nifty is up at 24,704, India rising on its own steam; gold pushed to near a record 4,279, the same nervous undercurrent keeping the expiry vol bid.

## DATA SOURCE

Data: NSE and BSE official close 05 August 2026, NSE FO BhavCopy 11 August chain, BSE FO 06 August Sensex expiry chain, NSDL and CDSL participant disclosures, Reserve Bank of India MPC decision 05 August 2026.

For four episodes the story was the same: the market was pricing calm far too cheaply into one day. That day is today. At 10 o'clock the Reserve Bank decides on rates, and the calm is gone. The fear gauge has climbed three sessions in a row, from a three month low of 11.76 to 12.19, the internal volatility read has gone from about 8 to almost 14, and the weekly straddle has roughly doubled. The vol expansion I flagged last Monday is here, and the professional desks that bought cheap insurance on both sides last week were right, and early.

First the housekeeping, because it decides how you read the screen. The new closing auction has now misfired two days running. Monday it printed the Nifty 188 points too high. Yesterday, on weekly expiry, it did it again, spiking the settlement about 120 to 150 points above where the market actually traded into the close. The screen says the Nifty settled at 24,614. The real level, from the futures and the Sensex, was closer to 24,516. And it stung, because on expiry options settle on that closing price, and the auction dragged the settlement above the 24,500 strike where the market was pinning, so the traders who correctly sold the 24,500 straddle got run over by a print, not by the market. Grade everything today off the real level near 24,516.

On the real tape yesterday was a quiet down day, the real Nifty off about a third of a percent and the Sensex, with a normal close, down just 0.27, the heavyweights Reliance and HDFC Bank doing the damage on weak breadth. A tired tape, waiting.

The positioning shows who is ready. The foreign funds are a protected long: short the index futures, but holding nearly 4,86,000 long puts and long a big stock book, and they bought another 2,446 crore of cash. The pros who were long volatility last week have taken the bet off, now short across futures, calls and puts, because their cheap options already did the job as the fear gauge climbed. They bought low, and they are trimming into the event.

Today's lesson is the exact mirror of last week's. Then I said buy the cheap insurance and own volatility into the event. Today I say the opposite, because that premium is now fully in the price. Buy an option at 9:15 into a 10 o'clock hold that 68 of 72 economists expect, and you pay peak premium for a boring outcome, then it evaporates the second the governor confirms the hold. That is the IV crush. The edge was owning it cheap last week. Today, if anything, sell the inflated premium after the print, do not chase it before.

The plan, in two halves. Before 10, a gap up that clears the 24,600 wall on a strong global tailwind, Wall Street ripped with the S and P up 1.8 percent and Asia ripping too, and crude stayed low near 79 dollars, so our futures point to an open near 24,750, but do not trust a gap-open above the wall before the governor speaks. The fresh weekly chain: max pain 24,500, the biggest wall 24,600, the put floor at 24,000. After 10, base case a hold and a vol crush that lets the market drift into a 24,500 to 24,600 pin. The tail is a hawkish hold, live because June inflation ran 4.38 percent, and it opens the downside toward 24,300 then 24,000, exactly what those 4,86,000 foreign puts protect. Trade the reaction, not the anticipation, and watch the 3:30 auction a third time.
