How to trade the rest of the week

SPY finished at 763.65 (−0.29%) against a put wall at 764. Not near it — through it. IWM did the same thing: 297.94 (−0.66%) against a put wall at 298. QQQ took the worst of it, −1.02% to 706.19, and is holding above its 705 put wall by 0.17% — call it holding by nothing.

Net dealer gamma is negative on all three. That flips hedging from damping to amplifying: dealers sell into weakness and buy into strength instead of the reverse, so ranges break rather than hold and realised volatility runs above what the chain is pricing.

None of the three currently prints a clean zero-gamma cross. That is not a data outage — it is what a one-sided book looks like. There is no nearby level where hedging flow changes sign, which means the regime does not change until the open interest itself does. We would rather tell you a level is absent than invent one. New to this? What gamma exposure actually is →

The put wall is the strike carrying the largest negative dealer gamma inside the near-money window. It is where hedging pressure is densest — and the direction of that pressure is the part most people get backwards.

Above the put wall, that concentration acts like a shock absorber. Below it, the same open interest is being hedged in the direction of the move: as price falls, dealers sell to stay neutral, which pushes price lower, which forces more selling. It does not hold you up. It moves you through.

So "SPY is at 764 support" is precisely the wrong read of Monday's close. 764 is the level that stops helping once you are under it, and both SPY and IWM ended the session on the wrong side.

SPY 767 (+0.44% from Monday's close). QQQ 714 (+1.11%). IWM 300 (+0.69%). All three lean the same way into Friday's expiry.

Max pain is a description of where open interest is concentrated, not a forecast, and it moves as positions roll. But when all three majors point the same direction at once while dealers are positioned to accelerate rather than absorb, it is worth knowing which way the pin is pulling.

Set against that: SPY ATM IV of 10% and an expected move of ±0.4% for a full session. The chain is pricing almost nothing while the structure has no cushion beneath it. Cheap optionality and no floor is the asymmetry of this week — not a directional call, an observation about what you are being charged for being wrong.

No mega-cap prints this week. Nothing on the slate moves the index by itself, which means the index moves on structure rather than news — and the single-stock risk concentrates almost entirely on Wednesday and Thursday afternoon.

Forty-seven reports land across Wednesday and Thursday, most of them after the close. In a negative-gamma tape with no flip on the board, that is where the week's realised volatility most likely comes from.

Most names are overpriced going into earnings — that is the whole reason the implied-vs-actual study exists. Across the tickers we track, the options are typically too expensive in 70–90% of reports.

AFRM is not one of them. Across 18 reports, the options priced a median 13.9% move and the stock actually delivered 15.6%. Implied has been too low, and it has been overpriced in only 44.4% of prints — close to a coin flip, against a 70–90% baseline. It reports Thursday, with the chain currently asking ±9.5%.

IREN runs the other way. 14 reports, implied a median 11.2% against an actual 9.5%, overpriced 64.3% of the time. Same Thursday session, opposite edge.

Two names, one afternoon, and the historical edge points in different directions for each. That is the entire argument for looking at implied versus realised instead of just reading the implied move off the chain. Run any ticker through the earnings analyzer →

SPY reclaiming 764 is the first thing that matters. Under it, hedging flow works against every bounce attempt, and "support" is not what that level is doing.

768 is the ceiling. That is the call wall and the top of the bracket. Nothing sustained happens above the tape without it going first.

QQQ 705 is the weakest line on the board — held by 0.17% after a −1.02% session. It is the most likely of the three to be the next one lost.

Wednesday and Thursday after the close is where the single-stock risk sits: 47 of the week's reports, and the two earnings edges above.

10% IV on SPY. In negative gamma with no cushion, long premium is cheap relative to what the structure can actually deliver. That is the week's asymmetry, and it costs very little to be wrong about.
