NQPOSITIVE

Net 0DTE gamma is POSITIVE on every measurement - native rebuild +$3.749B, ETF rebuild +$0.940B, published brief +$4.33B native and +$861M ETF - but net sign and LOCAL regime are different questions and here they disagree. Measured like-for-like by cumulative-strike crossing, the native rail puts the flip at 29,460-29,470, BELOW spot, while the ETF rail puts it at 29,626-29,667, ABOVE spot. The ETF rail arbitrates: within 1.5 percent of spot it carries 240,914 contracts against the native book's 7,483, a 32 to 1 depth ratio. So the working read is that price sits just BELOW its 0DTE flip inside a shallow negative-gamma pocket, with the flip roughly 29,700-29,725 on the futures axis overhead. That does not contradict an upward lean, it amplifies it: below the flip, impulses are not damped, so a push accelerates into the nodes above rather than being sold into. The same mechanism cuts both ways, which is why this instrument needs a tighter stop than the S&P today. Positioning is call-heavy on both rails and needs no model to see: net call open interest within 1.5 percent of spot is +70,862 on the ETF and +4,391 on the native book. Dollar-delta folded in here: net DEX +2,495 contracts-delta, rising from +1,757 this morning.

The clearest structure on this family and it is strike-located, not aggregate - the net aggregate is +629, essentially zero, and carries no information. The map does, and it is unusually tidy: ALL FOUR native antimagnets sit in a tight band from 29,507 to 29,597 which CONTAINS spot, and ALL FOUR magnets sit above it from 29,686 to 29,775. Price is inside a continuous repulsion zone with the entire attraction complex overhead. The strongest antimagnet is -20,028 at 29,567.3, and spot is essentially on it. The strongest magnet is +25,652 at 29,775.3, which is the largest vanna reading on either family today. Combined with the finding that price is below its flip and therefore undamped, this says the Nasdaq should move rather than sit, and the field says the direction of least resistance is up.

NEGATIVE and this is the day's cleanest cross-asset discriminator. Net charm opened at +13,575, flipped negative within the first polls and settled at -3,132, where it has stayed. The S&P over the same window ran positive and BUILDING, +1,890,041 to +2,433,005, a 28.7 percent increase. Negative charm means call delta bleeding away through the session - a mild drag against Nasdaq upside rather than a driver of downside. It is one of three independent reasons this report treats the S&P as the better vehicle today. No location is drawn from the charm centroid: the native and ETF centroid signs split on BOTH index pairs, which is the signature of a rail convention difference rather than a market disagreement, and CEX_PRESSURE_CENTROID_NOT_PRICE_TARGET applies regardless.

Net vomma positive at +17.4M and rising from 10.3M this morning - the book lengthens volatility as volatility rises. That matters more than usual with the volatility index at the 3rd percentile of 66 sessions, where there is no premium to cushion an event. Veta is folded in here because the schema has no VETA row: net veta +1.124e9, positive, so vega decays through the session and the book's volatility sensitivity is a morning phenomenon. Net rho +112,046 is also folded here and is very slightly larger than the S&P's despite a book an order of magnitude smaller.

Net ultima NEGATIVE at -120.9M against the S&P's +49.8M - the two indices carry opposite vol-of-vol convexity today. Negative ultima means the book's vomma shortens as volatility rises, so a genuine volatility expansion out of the Jackson Hole speech would be less well absorbed here than in the S&P. A second-order reason, consistent with the rest of the cross-asset picture, to prefer the S&P for directional risk. Net vera is also opposite-signed, +42,439 against -22,265.
