Daily Brief — Thu Sep 24, 2026

SPY's chain doesn't cross zero today — the second straight session with no clean zero-gamma flip. That's a genuine pattern worth flagging rather than a one-off: two days running, the cumulative dealer-gamma curve simply hasn't crossed the axis anywhere in the visible strike range.

The bigger change from yesterday is where spot actually sits: 763.32 is trading $0.68 below its own put wall (764) — already through the nearer structural level before the cash open, not testing it. Max pain (768) and the call wall (770) both sit well above current price. Expected move has also widened to ±1.7%, more than double Tuesday's ±0.7% — a much bigger range priced in on a day with one fewer structural level to lean on.

Put together: no flip, already under the nearest wall, and a wider expected range than the past two sessions. That's a different flavor of "no flip" than a tight, boxed-in day — this one has more room to actually move.

With the put wall already behind us and no flip to fall back on, there's no obvious structural floor directly under spot this morning. Max pain (768) and the call wall (770) are the levels standing between here and a real reclaim of the box from yesterday. A reclaim of 764 would put the put wall back to work as support; failing to reclaim it on a ±1.7% expected-move day leaves relatively open room below.

Two rows in today's raw sweeps feed — a GOOGL put and an NVDA call, both tagged with a 9/23 expiry — are left off this list: that expiry already passed, so those prints don't describe a live position today.

• 1SPY: the nearer wall is already gone. No flip, and spot opens under the 764 put wall — 768 (max pain) and 770 (call wall) are what's left overhead. A reclaim of 764 matters more than usual with no flip backing it up either way.
• 2DDOG's tripled-up ITM call sweep is the cleanest same-day conviction on the board — three separate prints, same strike, same expiry, on a name sitting a hair under its own flip.
• 3META's flow leans bullish but isn't clean — two calls and a put, same expiry. Weight the calls' larger combined size, but don't treat this as one-directional.
• 4CRWD and MCD are both worth a second look precisely because the flow disagrees with the structure — a put bought into a favorable zone (CRWD), and a call bought into a name that's both below its flip and past its own wall (MCD).
• 5MSTR and AMD both show the same odd quirk today — their own put wall sits fractionally above spot rather than below it. Worth knowing before leaning on "put wall = support" language for either name today.
• 6Keep size honest. A wider expected move on SPY, plus multiple names with mixed or contradictory structural reads, is not a setup that rewards forcing a single narrative on the whole tape.
