QQQ is 716.21 pre-open, up 11.49 points the morning after the Fed hiked, and it has pinned itself into the tightest gamma band this run has produced. Zero gamma is 715.87, 34 cents below. The call wall is 717, 79 cents above, and the GEX page rates it the strong magnet. Net GEX nearly tripled to +$953.9M on a 2.06 ratio, so above the flip the book dampens. The problem is how little room there is between above and below.
Spot is 716.21 on the bid, corroborated three ways: the watchlist bid at 716.21, the chart print at 716.22 and the InsiderFinance page at 716.08. Wednesday’s cash close was 704.72, so the index is up 1.63 percent before the bell. The extended session ran from a 704.19 low to a 716.78 high. Net GEX is +$953.9M on a 2.06 call/put ratio, with call GEX at $1.9B on 132,708 contracts against put GEX of −$901.3M on 247,126. Total GEX is $2.8B on 379,834 contracts. The run: $2.8B last Wednesday, $2.9B Thursday, $5.6B Friday by mid-morning, $845.4M Monday, $4.1B Tuesday, $2.9B Wednesday, and $2.8B this morning. Size is flat. The mix is not. Call contracts fell by about 3,100 while call gamma rose to $1.9B, because the calls that matter are now sitting on price. Put contracts rose by about 15,700 while put gamma fell, because the puts are now 16 points away.
Yesterday’s read called the flip at 704.16 the line, said the morning pin was not built to survive the 2:00 p.m. statement, and listed the 716 call concentration as an upside target only realistic as a post-decision move. The Fed hiked, the pin did not hold, and the index is now trading on top of that 716 level — but it got there overnight, not in the session. The downside path’s first leg did fire: price lost the 707.42 VAL, and the chart shows it working around 703, under the flip, in the last twenty minutes of the day before closing at 704.72. The chart on this screen only covers the end of Wednesday, so treat that as a partial scorecard. The upside path’s cash-session trigger above 710.28 is not something this chart window can confirm either. What is not in doubt is the call about the clock: a 34.59 percent 0DTE vol was pricing the decision, and the decision moved the index more than two implied moves.
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 2 snapshots since 8:50 a.m. ET — the page is current. Re-pull at 9:30 anyway. With the flip 34 cents from price, the first rebuild of the 0DTE book can move the line to either side of spot.
The Macro Tape
The Fed raised rates Wednesday and signalled more tightening. The tape is trading oil instead. The market-risk note on the wire has US stocks and Treasuries rising together as falling oil prices fuel optimism that inflation can be kept under control. US crude is back below $100 after reports that Saudi Arabia is offering more crude through Hormuz following a pipeline attack. At 7:58 a.m. ET, sources said China has privately asked Iran to use its influence to rein in Yemen’s Houthis after a Saudi appeal to Beijing, and the wire tags it dollar and WTI weaker, index futures stronger.
The rates side has not softened. Standard Chartered now expects another 25bp hike in December, against a prior forecast of no change this year. BoE Governor Bailey said policy may have to tighten if the Middle East conflict persists, which he called likely. And the 8:30 a.m. ET data gave the Fed no reason to stop. Initial claims printed 196k against 206.5k, continuing claims 1.730M against 1.779M, and the Philly Fed 37.8 against 32.1. Housing was the soft spot: starts 1.275M against 1.32M, permits 1.394M against 1.408M. A labour market that tight is a hawkish print into a rally built on disinflation hopes.
Vol is being sold hard. VIX is 15.43, down 2.28. /NQ is up 1.61 percent and /MES up 1.26 percent. The option chain tells a more careful story: the 0DTE expiry is at 32.07 percent implied vol with a ±5.204 move, against 27.64 percent for Friday’s quad-witching expiry and 20.66 percent for Monday. Yesterday’s 0DTE was 34.59 percent, so the event premium came out by only 2.5 points after the event passed. The front of the curve is still inverted by 4.4 points against Friday.
On single names, semis are leading again and by more. AMD is up 3.41 percent at 530.00 and INTC up 3.36 percent at 104.45. ON closed Wednesday at 66.60, well under the 74.00 it was bid at yesterday morning, and is up 2.48 percent at 68.25 — a bounce inside a much bigger giveback. SNOW is the only red name on the board.

The Line: 715.87
Zero gamma is 715.87, 34 cents under spot — 0.07 times the ±5.204 implied move. It is the line, and for practical purposes it is the price. The flip rose 11.71 points overnight, from 704.16 to 715.87, and the call wall moved up five strikes from 712 to 717. The whole book followed the gap. That is why the regime question today is not whether price can reach the line. It is which side of the line the first print lands on.
Above 715.87 dealers are long gamma, and the page’s first signal says it plainly: strong volatility dampening at spot, good for selling volatility. The heaviest call gamma on the map sits at 717, the next heaviest at 718, and the page flags 717 as a strong magnet. That is a pin with a 1.13-point floor-to-ceiling band between the flip and the wall. It is also why the squeeze screener, at 44, only reads possible. A book this long gamma above spot absorbs a squeeze rather than feeding one.
Below 715.87 the picture is different. Call gamma under the flip is a scatter of small bars from roughly 712 to 716. The put block does not start in size until about 703. Between those two there is not much for dealers to hedge against, and 704.72 — the close the gap came from — is 11.49 points down, 2.21 times the implied move. A thin book does not pin. It lets price travel. The put wall at 700 is 16.21 points below and 3.11 implied moves away, which puts it out of reach on a normal day, and the page still flags it as a strong volatility trigger if it trades.
Structure
POC is 710.45, VAH 713.05 and VAL 704.46. The value area is 8.59 points wide — five times yesterday’s — because it spans the whole overnight move. Spot at 716.21 is 3.16 points above VAH. Price is trading above value, not inside it, and the extended range runs 704.19 to 716.78.
Two clusters matter. At the top, the 715.87 flip, spot, the 716.78 extended high and the 717 call wall sit inside 1.13 points. That is the whole decision in one band. At the bottom, the 704.72 prior close, the 704.46 VAL and the 704.19 extended low sit inside 53 cents, with Wednesday’s 704.16 flip three cents under that. That is the gap origin, and it is where value ends. Between the two is VAH at 713.05 and POC at 710.45 — the first place an open that loses the flip would look for acceptance.
The wider frame is a market that spent the week failing at 710.28 and then cleared it by six points overnight on a macro headline, not in a cash session. Gaps made on thin overnight volume are not accepted until the cash market holds them. The first test of that is 713.05.
Cross-Asset
Yesterday’s post said semis were carrying the tape while megacap stepped aside. This morning both are bid, and semis are still doing more of the lifting.
SOXL is bid 113.81 against a 103.97 close, up 9.46 percent — the biggest move on the board for a third straight morning. It is 2.75 above its 111.06 VAH and 38 cents under its 114.19 period high, with POC at 107.93 and VAL at 105.90. Like QQQ, it is trading above value on an overnight move. SMH is up 2.70 percent at 560.31, AMD up 3.41 percent, INTC up 3.36 percent, AOSL up 3.28 percent, ON up 2.48 percent and NVDA up 2.25 percent. NVDA is the laggard inside the group again.
Megacap has rejoined, unevenly. AMZN is up 2.22 percent at 251.43, MSFT up 1.19 percent at 496.15, META up 1.14 percent at 681.00, and AAPL up only 0.52 percent at 334.14. SNOW is down 0.27 percent at 330.12, the only red name on the list. MAGS is near 70.52 against a 69.52 close, up about 1.44 percent, and sitting right at its 70.56 VAH with POC at 70.27, VAL at 70.19 and the period high at 70.78. Megacap is at the top of its value. Semis are well above theirs.
The index complex confirms the tilt. /NQ is up 1.61 percent against /MES up 1.26 percent. SPY is up 1.27 percent, IWM 1.39 percent and DIA 1.22 percent — a broad bid, not just tech. The leveraged pair tracks cleanly: TQQQ up 4.80 percent, SQQQ down 4.83 percent, SPXL up 3.76 percent, SPXS down 3.79 percent. VIX at 15.43 is down 2.28. Everything is agreeing, which is the point to be careful at: a one-way overnight tape leaves the cash open with nobody left to convince.
The Opening Call
The burden of proof is on the upside to hold 715.87 and accept through 717, and on the downside to lose 715.87 and then 713.05. The first half of each is 34 cents from spot. The default above the flip is a pin between 715.87 and 718, with 717 as the pull.
The honest read is non-directional, and this time the reason is geometry. A long-gamma pin with its floor 34 cents under price is a regime that can be lost on the opening print. Above the line, the book dampens and the magnet holds price near 717. Below it, the book stops dampening and the gamma underneath is thin all the way to the gap. Whichever side wins the first thirty minutes gets more follow-through than it deserves, and today the first thirty minutes also decide which book the rest of the day trades against.
One asymmetry is worth naming. The upside is capped by structure — 717, 718 and 721 are all call gamma dealers sell into, and the implied high is 721.41. The downside is not capped by structure until roughly 704.72, which is outside the expected range. That is not a forecast. It means that below the flip, nothing between 713 and 705 is obligated to stop the move — and the absence of a floor there is also the absence of a ceiling above it once the pin breaks.
Upside Path
Trigger: Hold 715.87 through the open, then acceptance above 716.78 and the 717.00 call wall on cash volume.
Targets: 718.00 call gamma, then 721.00 call gamma and the 721.41 implied high.
Invalidation: Loss of 715.87 zero gamma.
The first job is not losing the flip. The second is 717, which is both the heaviest call bar and the magnet, so the likeliest outcome of a clean open above the line is price getting pulled to 717 and stalling there. Acceptance above it opens 718, the second-heaviest bar, and in a long-gamma book the approach to 718 is a grind rather than a squeeze. 721 and the 721.41 implied high are the top of the expected range and would take real cash buying to reach, not just dealer flow. The invalidation is tight because the line is tight: back under 715.87, the regime this path depends on is gone.
Downside Path
Trigger: A clean break of 715.87 zero gamma on volume, then loss of 713.05 VAH.
Targets: 711.01 implied low and 710.45 POC, then the 704.72 prior close and 704.46 VAL.
Invalidation: Reclaim and hold 715.87.
A dip to 715.90 is the book working normally. A trade under 715.87 that holds is the one that changes the regime. Below it, dealers stop buying weakness, and VAH at 713.05 is the first level where the cash market has to decide whether it accepts the overnight gap. Losing it puts price back inside value, with POC at 710.45 and the implied low at 711.01 inside 56 cents of each other — the natural first stop. The gap fill to 704.72 and 704.46 is 2.2 implied moves away, which means reaching it takes more than drift. There is no scheduled catalyst big enough on today’s calendar, but the macro tape is a headline tape, and the Middle East thread that built this gap can take it back. The 700 put wall is not a target today; it is the level where the book’s hedging would accelerate if everything above it failed.
Catalysts
- 8:30 a.m. ET — already printed: initial claims 196k vs 206.5k forecast, continuing claims 1.730M vs 1.779M, Philly Fed 37.8 vs 32.1, housing starts 1.275M vs 1.32M, building permits 1.394M vs 1.408M. Labour hot, housing soft.
- 9:30 a.m. ET — re-pull the book. With the flip 34 cents from spot, the first rebuild decides the regime.
- 10:00 a.m. ET — pending home sales, forecast −0.1 percent vs −2.3 percent prior.
- 1:00 p.m. ET — 10-year TIPS auction; prior high yield 2.438 percent, bid-to-cover 2.300. The first real-yield test after the hike.
- Middle East headlines are the driver: China’s reported request to Iran on the Houthis, and Saudi crude through Hormuz after the pipeline attack. Oil below $100 is what the rally is built on.
- Rates repricing: Standard Chartered now sees a December hike; BoE’s Bailey flagged tightening risk if the conflict persists.
The Week Ahead
Friday, September 18 — quad witching. Industrial production at 9:15 a.m. ET, forecast +0.3 percent vs +0.2, with capacity utilization forecast 76.4 percent vs 76.3. Then the first Fed voices after the hike: Bowman at 9:30 a.m. ET and Schmid at 11:45 a.m. ET. Friday’s expiry is carrying 27.64 percent vol and a ±9.29 move, and the book has held near $2.8B to $2.9B for three sessions. Expect Friday’s levels to be set by the expiry rather than the tape.
Next week — the 2-year note auction is Tuesday, September 22 at 1:00 p.m. ET, with flash PMIs on the same day’s calendar. Micron reports September 30, the following week, which matters for a semis complex that has led three mornings running. No market holidays in this window.
