SPY closed Friday at 776.34, down 0.20%. Net dealer gamma across the chain is +$127M per 1% move, which on a screener reads like a quiet, well-cushioned tape. It isn't one. Split the same chain at spot and you get the actual picture:
Every single strike from 767 through 776 carries negative gamma — −$510M stacked in a ten-point band directly under the market, led by 775 at −$143M, 770 at −$107M and 772 at −$85M. The only positive strike inside that band is 774 (+$39M), and it is one strike wide. Start at 777 and the sign inverts for good: +$74M at 778, +$95M at 779, +$259M at 780 — +$625M of damping between 777 and 785.
That asymmetry is the week. It says a grind higher gets slower and slower into the 780 wall, and a break lower gets faster. Max pain sits at 775, one point under Friday's close, so the pin has gravity right where the negative stack begins. New to this? What dealer gamma exposure actually is →
| Index | Fri close | Net GEX | Flip | Put / call wall | Read |
|---|---|---|---|---|---|
| SPY | 776.34 | +$127M | 783.36 | 775 / 780 | Below flip Cushion is 0.95% overhead |
| QQQ | 731.07 | +$422M | 729.83 | 724 / 735 | In zone by 0.14% — one bad hour of cushion |
| IWM | 305.09 | +$244M | 304.05 | 301 / 306 | In zone The only clean book on the board |
| DIA | 536.80 | +$34M | 547.22 | 535 / 541 | Below flip by 2.03%, and −$29M sits at 535 |
Two of four majors below their zero-gamma line is what our own regime scan calls BROKEN — trade with momentum, not against it. The nuance worth holding: QQQ and IWM are the two that still have a floor, and IWM's is real — +$265M of positive gamma against only −$21M negative, with a +$104M block sitting at the 306 call wall. Small caps are the tightest-pinned, best-cushioned thing on the board, which is not a sentence we get to write often.
QQQ is the fragile one. It closed 0.14% above its 729.83 flip. Above the line, +$501M of damping; below 724, the book turns negative. That's not a cushion, it's a coin resting on its edge — and it's the tell we'll be checking first every morning.
There is no CPI, no PPI and no jobs report this week. Last week's inflation data is behind us and the next payrolls print is not. That matters more than it sounds: when the macro is second-tier, the tape gets driven by positioning and expiry mechanics instead of headlines — which is exactly the setup section 1 just described.
| Day | Time | Event | Why it matters |
|---|---|---|---|
| Mon 8/17 | 8:30a 10:00a | Empire State Mfg (Aug) NAHB Housing Index (Aug) | Second-tier. Monday's job is to see whether 776 holds without help. |
| Tue 8/18 | 8:30a 9:15a | Housing starts & permits (Jul) Industrial production (Jul) | Housing data lands the same morning HD reports — the two read each other. |
| Wed 8/19 | 2:00p | FOMC minutes (July 28–29) | The week's one real macro event. Minutes from the meeting that held the funds rate at 3.50–3.75%. A 2pm release into a market with no floor under it. |
| Thu 8/20 | 8:30a 10:00a | Jobless claims · Philly Fed (Aug) Leading indicators (Jul) | Claims is the labour proxy that matters while payrolls is three weeks out. |
| Fri 8/21 | 9:45a all day | S&P Global flash PMIs (Aug) Monthly OPEX | August monthly expiry. The chain that's pinning the tape all week rolls off. |
Wednesday 2:00pm is the fuse. The minutes land into a market sitting one point above a −$510M gamma pocket. If they read hawkish and SPY loses 775, dealer hedging works with the move rather than against it — that's the single scenario this week most likely to produce a real range instead of a grind.
Tech season is over; this is the consumer read. Nine names carry the week, and the implied move below is what the options are pricing for the post-print swing — not a direction. Click any ticker for its full earnings analyzer (implied vs how the stock actually moves).
| Day | Name | Implied | Dealer positioning into the print |
|---|---|---|---|
| Mon 8/17 | FN amc | ±10.6% | The biggest implied move of Monday, and the only one worth a slot. |
| Tue 8/18 | HD bmo | ±3.6% | Below flip by 8.9% (368.57 vs 338.55). Wall 350, put wall 335, and only +$3M of net book. |
| Wed 8/19 | TGT bmo | ±5.8% | Above flip — but trading through its 150 call wall at 154.52. Past-wall is a low-reward place to be long. |
| Wed | LOW bmo | ±4.5% | Negative gamma No flip anywhere in the chain. Dealers amplify both directions. |
| Wed | TJX bmo | ±3.4% | Negative gamma −$8M net, with −$9.9M parked at the 145 put wall. |
| Wed | ADI bmo | ±5.3% | Below flip by 4.9%. The one semi in a consumer week — wall at 395. |
| Wed | WOLF amc | ±14.9% | ATM IV 182. Options are already priced for chaos: 1σ to Friday is ±19.1%. |
| Thu 8/20 | WMT bmo | ±4.2% | Negative gamma The week's biggest print has no flip and −$10.2M sitting at 119, just above spot. |
| Thu | BABA bmo | ±5.9% | Below flip by 1.8% — the flip at 126.17 is inside the implied move. Wall 130. |
| Thu | DE bmo | ±4.6% | No book Net dealer gamma rounds to zero. Nothing damps this one either way. |
| Thu | ROST amc | ±5.9% | Negative gamma −$3.6M at the 220 put wall, and 8.2% of 1σ between here and Friday. |
The number that frames the whole week: those nine headline reporters carry +$12M of net dealer gamma between them. NVDA's 230 strike alone carries +$172M. Four of the nine are in outright negative gamma and three more are below their flip — there is no dealer cushion anywhere on this slate. Post-print continuation is the higher-probability behaviour here, not the usual fade.
This is the trade the structure is handing us. Below 775 and dealers are selling into weakness with nothing but a −$510M pocket down to 767: that's the momentum-short/put side, and it needs no forecast, only the level. Above 778, the +$625M stack takes over and the honest read is that upside gets slow and capped near 780 — a grind to sell into, not a breakout to chase. Between 775 and 778 there is nothing to do, and Monday will probably be exactly that.
If we want risk-on exposure this week we'd rather own it in small caps than in an index whose cushion is above the market. IWM is pinned between the 301 put wall and a +$104M block at 306, with 13× more positive gamma than negative. Two ways to play it and they're opposite trades: fade the edges of 301–306 while the pin holds, or take the break above 306 seriously, because above the wall the damping stops.
WMT, TJX, LOW and ROST all report into negative dealer gamma. That means the hedging flow after the print pushes the move further rather than absorbing it — the reaction tends to trend rather than mean-revert. We are not buying lottery tickets into the release; we're waiting for the gap, letting the first 30 minutes set the range, and trading the continuation with the structure. Check implied vs actual history first →
±14.9% implied on 182 IV. This is the one name on the board where the options are priced for a real event, which cuts both ways: the move can be enormous and still lose money on a long premium position. It goes in the small-size bucket or it doesn't go on at all.
August monthly expiry with flash PMIs at 9:45a. We wrote the same thing before the last two expiries and it was right both times — last Friday's OPEX went 5–6 and cost 1.0% on average while the rest of the week ran 68% winners. Expiry days aren't unprofitable because the read is wrong; they're unprofitable because there's no room in either direction. Smaller size, shorter holds.
What makes us stand down: a Monday gap straight into 778–780 leaves no reward on the long side and we simply won't chase it. And if QQQ loses 729.83 while SPY is already below its flip, that's three of four majors short-gamma at once — at that point the only trades we want are with the trend, held short, and half size.
Next week is the setup week, not the payoff week. NVDA reports Wednesday Aug 26 on a ±5.7% implied move — sitting on +$618M of net dealer gamma, 12% above its own flip, with a +$172M call wall at 230. And the Jackson Hole symposium runs Aug 27–29, with the Fed chair's keynote Friday morning. That's the two-day window that sets the tone into September.
Trading Aug 17–21 like it's the main event is how people arrive at the actual main event with no capital and no patience. Take the clean levels, skip the rest.
