QQQ is 708.01 pre-open, up 3.47 points on a retail sales print that came in hot across every line, and it is back above zero gamma for the first time this week. The flip has dropped to 704.16, 3.85 points below. The call wall is 712, 3.99 points above. For the first time in this run the book is net long gamma — +$356.9M on a 1.29 ratio — which means the morning should dampen, not amplify. The afternoon is another matter. FOMC lands at 2:00 p.m. ET with a hike in the forecast column, and 0DTE vol at 34.59 percent is pricing that, not the morning.
Spot is 708.01 on the bid, corroborated three ways: the watchlist bid at 708.01, the chart print at 707.98 and the InsiderFinance page at 707.75. Tuesday’s cash close was 704.54, so the index is up 0.49 percent before the bell. The chart’s range runs from a 710.28 high to a 703.64 low, and Tuesday never got back above 710.28. Net GEX is +$356.9M on a 1.29 call/put ratio, with call GEX at $1.6B on 135,839 contracts against put GEX of −$1.2B on 231,396. Total GEX is $2.9B on 367,235 contracts. The run: $2.8B last Wednesday, $2.9B Thursday, $5.6B Friday by mid-morning, $845.4M Monday, $4.1B Tuesday, and $2.9B this morning. The book got smaller overnight, but the mix changed more than the size. Put gamma halved from −$2.6B to −$1.2B while call contracts rose from 98,035 to 135,839. Yesterday’s book was put-heavy and short gamma. Today’s is balanced and long gamma.
Yesterday’s read called the flip at 712.55 the line and put the burden on both sides: clear 710.28 then 712.55 to go up, lose 707.96 POC then break the 705 put wall to go down. The downside path fired. Price lost POC, broke 705, and ran through the 704.23 VAL and the 704.16 period low to print 703.64 — 52 cents past the listed targets and well short of 700. The upside path never triggered: 710.28 held and 712.55 never traded. The close at 704.54 was below the put wall. The call worth keeping was the one about the magnet: a strong magnet below the flip in a short-gamma book is a pull, not a floor, and it pulled.
Written at 8:57 a.m. ET, thirty-three minutes before the open. Spot is live and corroborated across the watchlist bid, the chart print and the GEX page, and the InsiderFinance snapshot is stamped 14 snapshots since 8:43 a.m. ET — the page is current. Re-pull at 9:30 anyway, because the 0DTE book rebuilds through the first hour, and today it will rebuild again into 2:00 p.m.
The Macro Tape
The 8:30 a.m. ET data was hot on every line. Retail sales rose 1.2 percent against a 0.8 percent forecast, with the prior revised from −0.6 to −0.5 percent. Core retail sales rose 1.4 percent against 0.6 percent, from −0.3 percent. Import prices rose 0.7 percent against 0.5 percent, from −0.4 percent. That is a consumer rebounding hard and an import price line turning up, six hours before a Fed decision.
The calendar still carries the rate decision at 4.00 percent against a 3.75 percent prior — the 25bp hike that moved into the consensus column on Monday night held through Tuesday. The projections are forecast higher on every horizon: the current-year median at 4.125 against 3.75, next year 3.875 against 3.625, two years out 3.625 against 3.375, three years out 3.375, and the long run 3.125 against 3.063. Hot data does not make that harder to deliver. It makes it easier.
The tape is reading it as relief anyway. The market-risk note on the wire has US stocks and Treasuries catching a bid after days of selling as traders wait for the decision and the updated projections. /NQ is up 0.49 percent and /MES up 0.29 percent. VIX is 16.72, down 0.48. The divergence worth watching is in the option chain: the 0DTE expiry is at 34.59 percent implied vol with a ±5.618 move, against 28.03 percent tomorrow and 27.40 percent Friday. Yesterday 0DTE was 25.06 percent. The front of the curve is inverted by more than six vol points, and all of that premium is sitting on one timestamp.
Underneath, Middle East flow continues. US officials met the Houthis in Oman over the weekend after an Iran-backed group seized a strategic stretch of the Red Sea coast, and the wire tags it oil weakness and S&P strength. Iran’s and China’s foreign ministers discussed war and diplomatic solutions. On the single-name side, the NYC Council has set a public hearing on AI for October 5, and its speaker has asked the OpenAI and Anthropic chief executives to attend — a headline, not a catalyst, but it keeps AI regulation on the screen on a day semis are leading.
The Gamma Map
| Level | Price | What It Is |
|---|---|---|
| 0DTE Call Concentration | 716.00 | $37.1M on the 0DTE heatmap — where the call side is parked |
| Implied High | 713.63 | Upper bound of the 0DTE expected move |
| Call Wall | 712.00 | Peak call gamma bar; 0.71x the implied move, inside the range |
| Prior High | 710.28 | Top of the chart range; held Tuesday |
| PH | 709.18 | Study period high |
| VAH | 709.08 | Value area high |
| SPOT | 708.01 | Bid; inside a 1.66-point value area, above the flip |
| POC | 707.73 | Point of control |
| VAL | 707.42 | Value area low |
| Call Gamma Edge | 706.00 | Lower edge of the call gamma block |
| PL | 705.57 | Study period low |
| Prior Close | 704.54 | Tuesday cash close |
| Zero Gamma | 704.16 | The flip; 0.69x the implied move below; rated moderate support |
| Prior Low | 703.64 | Tuesday’s low |
| Implied Low | 702.39 | Lower bound of the 0DTE expected move |
| Put Wall / Magnet | 700.00 | Heaviest put gamma; strong magnet and strong volatility trigger below; 1.43x the implied move |
| Put Gamma Bars | 695.00 / 690.00 | Secondary put gamma below the wall |
The Line: 704.16
Zero gamma is 704.16, 3.85 points under spot — 0.69 times the ±5.618 implied move, and inside the expected range with 1.77 points to spare above the 702.39 implied low. It is the line. The flip dropped 8.39 points overnight, from 712.55 to 704.16, and price went from 3.44 points under it to 3.85 points over it without the index having to do much. The book moved to the price more than the price moved to the book.
Above the flip the regime inverts from yesterday. Dealers are long gamma: they sell strength and buy weakness, and the GEX page’s first signal says exactly that — strong volatility dampening at spot, good for selling volatility. The call gamma block starts at roughly 706 and peaks at the 712 call wall, with the 708 bar almost as heavy. Spot is sitting on that block. That is what a pin looks like, and it is why the squeeze screener fell from 68, likely, to 39, possible. A long-gamma book does not squeeze. It absorbs.
Below 704.16 the character flips back to yesterday’s. The put wall at 700 is 8.01 points under spot, 1.43 times the implied move and outside today’s expected range, and the page flags it twice again: a strong magnet, and a strong volatility trigger below it. The shape between 704.16 and 700 is Tuesday’s shape — short gamma, dealers selling into weakness, a magnet at the bottom. Tuesday showed what that pull does once the flip is lost.
The complication is the clock. A long-gamma pin is a morning structure. The 34.59 percent implied vol is an afternoon price. Dealers dampening a range at 10:00 a.m. says nothing about whether the same book holds a statement and a dot plot at 2:00 p.m., and a 0DTE book this size gets rebuilt in the minutes after the decision.
Structure
POC is 707.73, VAH 709.08 and VAL 707.42. The value area is 1.66 points wide, and spot at 708.01 is 28 cents above POC, in the lower half of value. The study period range is 705.57 to 709.18, and 709.18 sits ten cents above VAH — the top of the premarket run and the top of value are the same level.
Two clusters matter. Overhead, VAH 709.08, PH 709.18 and the 710.28 prior high sit inside 1.20 points, with the 712 call wall 1.72 points above that. That is the resistance stack, and in a long-gamma book it is reinforced rather than fragile. Below, the prior close at 704.54, the flip at 704.16 and Tuesday’s 703.64 low sit inside 0.90 points. That is the shelf that decides the regime. Between the two is a 4.5-point band holding the whole value area, the 705.57 period low and the 706 edge of the call block.
The wider frame is a market that went 709 to 703.64 and back to 708 in a day — a round trip across the entire gamma map with nothing resolved. The chart’s 710.28 high is still the level every session this week has failed to hold above.
Cross-Asset
Yesterday’s post called the flat index a cancellation — semis bid, megacap offered — and said it only needed one side to stop for the index to move. The megacap side stopped. Semis kept going.
SOXL is bid 106.75 against a 102.32 close, up 4.33 percent — the biggest move on the board for a second straight morning. It sits above its 106.38 POC and below its 107.19 VAH, with VAL at 105.31 and the period range 103.54 to 107.51. INTC is up 3.84 percent at 100.87, back above 100. AMD is up 1.82 percent at 513.40, SMH up 1.25 percent at 548.90, ON up 1.09 percent at 74.00, NVDA up 0.75 percent at 213.77. That is the third straight session INTC has changed direction, which still reads as a crowd trading the name rather than owning it.
Megacap is mixed, not offered. META is up 0.79 percent at 675.54, AMZN up 0.21 percent at 248.95, AAPL flat at 331.30, MSFT down 0.32 percent at 495.52. SNOW is again the weakest name, down 0.92 percent at 320.00. MAGS closed 69.60 and is bid near 69.70, at the bottom of a 69.66-to-70.56 value area with POC at 70.27 and the period high at 70.90 overhead. Megacap is not leading. It has just stopped subtracting.
The index complex confirms tech leadership. /NQ is up 0.49 percent against /MES up 0.29 percent. SPY is up 0.29 percent, DIA 0.21 percent, IWM 0.23 percent. The leveraged pair tracks cleanly: TQQQ up 1.41 percent, SQQQ down 1.45 percent, SPXL up 0.84 percent, SPXS down 0.89 percent. VIX at 16.72 is down 0.48. The index is quiet, but this time the quiet is not two trades cancelling. It is one trade — semis — carrying the tape while the other side steps aside.
The Opening Call
The burden of proof is on the upside to accept above 709.18 and on the downside to lose 704.16. Neither is close. Spot is 1.17 points under the first and 3.85 over the second, inside a 1.66-point value area, sitting on a call gamma bar, in a long-gamma book. The default for the morning is compression between roughly 706 and 710.
The honest read is non-directional until 2:00 p.m. ET, and the reason is not balance this time — it is the clock. A hot retail print into a hike-priced FOMC and a tape that rallied on it is a setup that can be wrong in either direction at 2:00. The options market agrees: it is charging 34.59 percent for today and 28.03 percent for tomorrow. Whatever the morning does, the pin was not built to survive the statement, and whichever side wins the first thirty minutes after 2:00 gets more follow-through than it deserves.
One asymmetry is worth naming. Above the flip, the book dampens. Below it, the book amplifies toward a strong magnet at 700 that sits outside the expected range. A long-gamma morning makes the downside path slower to start, and a short-gamma afternoon below 704.16 would make it faster to finish. That is not a forecast — it means that once the flip goes, nothing between it and 700 is obligated to stop the move.
Upside Path
Trigger: Acceptance above 709.18 PH and the 709.08 VAH on cash volume, then a break of 710.28.
Targets: 712.00 call wall, then 713.63 implied high and the 716 call concentration.
Invalidation: Loss of 707.42 VAL.
The first job is the top of value. 709.08 and 709.18 are the same level for practical purposes, and 710.28 is 1.10 points above that — the high this market has failed to hold all week. In a long-gamma book, the approach to 712 is a grind, not a squeeze: dealers sell into it, and the call wall is where that selling is heaviest. So 712 is the target and also the likely stall. 713.63 and 716 are only realistic as a 2:00 p.m. move, not a morning one, and a morning break above 710.28 before 10:00 a.m. on an FOMC day deserves the usual suspicion. The path is invalidated on a loss of VAL at 707.42, which puts price back under value with the call block thinning beneath it.
Downside Path
Trigger: Loss of 707.42 VAL and 705.57 PL, then a clean break of 704.16 zero gamma on volume.
Targets: 703.64 prior low and 702.39 implied low, then the 700.00 put wall.
Invalidation: Reclaim and hold 707.73 POC.
A drift from 708 to 706 is the book working normally and tells you little. The period low at 705.57 and the prior close at 704.54 are the first real tests, and 704.16 is the one that changes the regime. Below it, dealers flip from buying weakness to selling it, and the shelf underneath is short: Tuesday’s 703.64 low is 52 cents lower and the implied low is 1.25 points below that. 700 is outside the expected range, which means reaching it requires an event — and there is one on the calendar. The put wall is rated a strong magnet and a strong volatility trigger below, so a trade through 700 is where the book’s hedging accelerates, with more put gamma at 695 and 690. Yesterday this path ran 52 cents past its listed targets and stopped. Today the magnet is closer to the bottom of the range, not farther.
Catalysts
- 8:30 a.m. ET — already printed: retail sales +1.2 percent vs +0.8 forecast, core +1.4 vs +0.6, import prices +0.7 vs +0.5. Hot across the board.
- 9:30 a.m. ET — re-pull the book. The long-gamma read depends on the flip staying under price.
- 10:00 a.m. ET — NAHB housing index, forecast 34 vs 35 prior; business inventories, forecast +0.8 percent vs 0.0.
- 10:30 a.m. ET — EIA crude inventories, forecast −1.5M vs −0.391M prior.
- 2:00 p.m. ET — FOMC rate decision, statement and SEP. Forecast 4.00 percent vs 3.75 percent. Median dots forecast higher on every horizon.
- 2:30 p.m. ET — FOMC press conference.
- 7:00 p.m. ET — Trump speaks, after the close.
- Middle East headlines are live: US-Houthi talks in Oman after the Red Sea coast seizure, and Iran-China foreign minister contact.
The Week Ahead
Today is the week. Two sessions follow it, and both will trade the decision.
Thursday, September 17 — initial jobless claims at 8:30 a.m. ET, forecast 206.5k against 206k, with building permits at the same time. The first labour print after a decision that may have been a hike.
Friday, September 18 — quad witching. Total GEX went $4.1B to $2.9B overnight even as the expiry approaches, so the build into Friday is not linear. Expect the post-FOMC book to reset Thursday and Friday’s levels to be set by the expiry rather than the tape. No market holidays this week, and no index-weight earnings on the board — everything between now and Friday is macro and positioning.
Levels are levels. Wait for the trigger, know your invalidation before you enter, and size to your own risk tolerance and account.
