Friday’s book expired and took the floor with it. Zero gamma is now resistance at 714.44, spot is underneath it, and the next real support is 24 points lower. Thin tape, live headlines, and no cushion.
QQQ comes into Monday around 714.00 after Friday’s brutal reversal — 724.13 high, 714.52 low, and a close that gave back the entire post-NVDA recovery. Net GEX reads +$547.7M with a call/put ratio of 1.69, so dealers are nominally still long gamma. But look at the size: total GEX has collapsed from $6.4B on Friday to $2.1B as the weekly expiration rolled off. The dampening mechanism that absorbed every dip last week is a third of what it was. Same sign, far less force.
The Macro Tape
Two threads, and the newer one matters more this morning.
Geopolitics moved to the front. Trump said at 8:25 ET that the US will respond to Iran’s attack on US forces. Crude strengthened, equity indexes weakened. CENTCOM has since stated that no ships have hit mines in the Strait of Hormuz, which walks back one tail but not the broader one. This is a binary, headline-driven risk that gamma levels cannot price — when a wire hits, the map gets redrawn, not respected.
The Warsh hangover is still on the tape. Global stocks and gold retreated into the weekend as the Chair’s hawkish Jackson Hole remarks pushed expectations toward a hike next month. VIX is up nearly a full point to 15.39 pre-market. The market spent last week arguing about the pace of cuts and enters this one pricing the opposite direction.
Two single-name items worth knowing. NVIDIA is investing $3.5B in MediaTek — constructive for NVDA. And China’s CXMT is reported to have made a breakthrough in HBM3E, the high-bandwidth memory used in leading AI processors. That second one is a slower burn but it cuts at the moat premium embedded in the entire US memory and semi complex.
The Gamma Map
| Level | Price | What It Is |
|---|---|---|
| Call Wall | 730.00 | +2.24% — far overhead, not today’s problem |
| Prior Day / Prior Week High | ~724.00 | Friday’s high water mark |
| Overnight High | 717.51 | Session high so far |
| VAH | 716.23 | Value area high |
| 21 EMA | 715.63 | Cloud top — bearish, 9 below 21 |
| POC | 715.62 | Point of control |
| 9 EMA | 715.12 | Under the 21 |
| Zero Gamma | 714.44 | RESISTANCE — flagged as the level where dynamics change |
| Spot | 714.00 | Sitting directly beneath the line |
| VAL | 713.93 | Value area low |
| Prior Low | 713.70 | Friday’s reference |
| Overnight Low | 711.26 | Session floor |
| Put Wall | 690.00 | -3.36% — strong vol trigger, and 24 points away |
Read the walls against each other, because the geometry is the story. Call wall 730, put wall 690 — forty points apart, with only 2.4% of open interest expiring today. That is not a pinned board; that is an open field. Call GEX of $1.3B against put GEX of -$797M across 669,675 total OI is a thin, unopinionated book.
The consequence matters more than the numbers. Last week every flush found a bid at a level because dealers were long enough gamma to catch it — the 10 AM Friday break stopped dead at zero gamma to the tick. This morning, if 714.44 gives way, the nearest structural support on the gamma map is 690. There is no shelf in between. That does not mean price goes there. It means nothing on this board is obligated to stop it.
The Line: 714.44
Zero gamma has flipped to the wrong side of price. All last week it sat below spot as support; today it sits above at 714.44, tagged MODERATE resistance with the note that market dynamics change significantly if breached.
Above it, dealers are long gamma, hedging dampens, and dips get absorbed. Below it, dealers are short gamma, hedging amplifies, and every move gets help. Spot at 714.00 is forty-four cents underneath. That is the whole session compressed into one number, and it is the first thing to watch at the bell.
Structure
The cloud is bearish with the short average under the long one, and price has been rejected from the 715.62 POC repeatedly overnight. Value is defined tight at 713.93 to 716.23. The overnight session already made a full round trip — 711.26 low, 717.51 high — before settling back onto the pivot, which tells you both sides showed up and neither won.
Wider frame: QQQ topped at 735.86 on August 17, bottomed near 705 on the 25th, recovered to 724 on Friday morning and gave all of it back by the close. Two weeks of lower highs. The 730 call wall sits just under the old high, which is where this argument eventually gets settled — but that is a long way from here.
Cross-Asset
Semis are the wreckage from Friday and haven’t repaired. SOXL sits at 111.34, hugging its value area low near 111.53 and below both short-term averages after a double-digit decline. SMH and NVDA both closed near their lows. The CXMT memory headline lands on a complex that has no cushion.
Mega-cap is the less-bad side, but only barely — MAGS at 69.07 carries a bearish cloud with price only just above its short average and value area low at 68.48 uncomfortably close. Last week’s pattern was mega-cap holding the index up while semis bled. If MAGS loses its value area, that crutch is gone and there’s no third leg.
The Opening Call
The burden of proof is on the bulls, and it has a specific address: 714.44. Until that reclaims, this is a market trading beneath its own gamma flip with a third of last week’s cushion, a hawkish Fed repricing, and a live military headline. That combination argues for respecting downside more than the chart alone would suggest.
But thin books cut both directions, and the screener has a bullish squeeze flagged as likely at 50/100 for a reason. With so little dealer gamma pinning anything, a reclaim of 714.44 that holds gets to 715.62 POC and 716.23 fast, because there is no supply structure to fight either. The same absence of a floor is an absence of a ceiling.
So the honest read is not directional — it is that whichever side wins the first thirty minutes gets more follow-through than it deserves. Size accordingly, and do not assume the level that held last week will hold this week. The book that made those levels expired Friday.
Upside Path
Trigger: a tick-chart close above 714.44 that holds, with volume expansion and MAGS holding above 68.48.
Targets: 715.62 POC, then 716.23 VAH, then 717.51.
Invalidation: a close back under 713.93.
Above zero gamma the dampening returns and the tape gets orderly. Note that the 9 and 21 EMAs sit at 715.12 and 715.63 in a bearish configuration — that cluster is the real test, not the gamma line.
Downside Path
Trigger: rejection at 714.44 followed by a closing break of 713.70.
Targets: 711.26 overnight low first, then open air — the next gamma structure is 690.
Invalidation: a reclaim of 714.44.
This is the path with the thinner air beneath it, which is exactly why it deserves respect rather than enthusiasm. Below the overnight low there are no dealer levels to lean on, and in a short-gamma regime that is when moves stop being orderly. Take profits at levels rather than pressing for a number the map does not actually provide.
Catalysts
- Iran headline risk, all session. A US response to the attack on US forces is stated policy as of this morning. Crude is the tell — if WTI accelerates, equities follow the other way.
- Trump healthcare announcement at 3:00 PM ET — late-day headline risk into the close.
- Month-end. Rebalancing flows can override structure in the final hour, and August is closing near its lows.
The Week Ahead
Tuesday is the real test: Fed’s Barr at 9:05 ET, S&P Manufacturing PMI Final at 9:45, then ISM Manufacturing at 10:00 ET with consensus 55.2 against 55.6 prior. That number carries extra weight after Chicago PMI collapsed to 47.1 on Friday — if ISM confirms the weakness, the growth scare becomes the story and the hike argument gets much harder to make. JOLTS lands the same minute at 7.313M expected.
Then ADP Wednesday, AVGO earnings Wednesday after the close at 4:15 ET — the semi complex’s next referendum after NVDA — and jobless claims Thursday. A quiet Monday would be a gift, and the calendar suggests the market won’t get many more this week.
Levels are levels. Wait for the trigger, know your invalidation before you enter, and size to your own risk tolerance and account.
