SPY's gamma tool reported a zero-gamma flip of 655.04 this morning — 15.3% below spot — the same kind of break this series has now caught several times. Pulling the raw per-strike data directly: the chain crosses cleanly from −$2,218.7M at 775 to +$176.0M at 776 — a real flip around ~775.9, putting spot (774.33) just 0.21% below it. That's not just a correction, it's another entry in the razor-thin-flip pattern this board keeps flagging week after week.
UNH also reported a missing flip today, and its raw data told a real story too — noisier than SPY's clean crossing (the sign flips back and forth a few times through 370–380), but with a genuine, sustained crossing into positive territory between 375 (−$25.0M) and 380 (+$2.9M). Corrected flip: ~377.2, putting UNH's spot (375) about 0.6% below it — thin, but real.
Spot, the put wall (775) and the corrected flip (~775.9) are all within two dollars of each other — another compressed stack. Reclaim and hold above ~775.9 and SPY is in positive gamma with the 778 call wall as the next real check; stay below it and the put wall sits almost directly on top of spot, offering very little room either way.

| Ticker | Spot | Flip | Call Wall | Status | Today's flow |
|---|---|---|---|---|---|
| MU | 1071.35 | 1128.89 | 1100 | BELOW FLIP | $950P 3/19/27 — $962,153, the single largest print of the day, a LEAPS put over a year out. Also $1120C 10/9 — $276,270, a near-term bullish bet in the opposite direction. A big long-horizon bearish thesis sitting alongside a small near-term bullish one. |
| AAPL | 337.06 | 336.29 | 340 | IN ZONE | Three calls, all bullish, zero puts — $325C 10/16 $536,000, $330C 10/16 $372,000, $345C 10/16 $176,000 — $1,084,000 combined, all same expiry. AAPL is just 0.23% above its own flip, a favorable but razor-thin structure underneath real conviction. |
| MRVL | 278.26 | 288.88 | 300 | BELOW FLIP | $300C 12/18 — $397,576, a two-and-a-half-month-out bullish bet struck right at the call wall. MRVL is 3.7% under its own flip — betting on clearing real structural distance. |
| NVDA | 235.22 | 238.91 | 240 | BELOW FLIP | Three calls, all bullish, zero puts, three different expiries — $235C 10/23 $365,000, $237.5C 10/16 $144,550, $235C 10/9 $138,205 — $647,755 combined. Real conviction betting against a 1.6% below-flip structure. |
| UNH | 375.00 | ~377.2 | 400 | BELOW FLIP | No sweep large enough for today's top 15, included for the flip correction above. Flip ~0.6% away — thin, noisy data, worth rechecking before the open. |
| GOOGL | 351.15 | 347.61 | 355 | IN ZONE | $340P 10/16 — $196,470, a bearish bet below spot and below the put wall (340 itself). GOOGL is comfortably in zone (1.0% above its flip), so this flow runs against a favorable structure. |
| COF | 194.00 | 203.79 | 200 | BELOW FLIP | $170P 9/17/27 — $175,403, a LEAPS put nearly a year out. COF is 4.8% under its own flip — a long-horizon bearish bet consistent with the current negative-gamma read. |
| AMZN | 258.58 | 250.27 | 260 | IN ZONE | $260C 10/16 — $157,986, struck just above spot and right at the call wall. AMZN is 3.3% above its own flip — a favorable structure backing a bullish bet at the exact resistance level. |
