Zero-Day Expiry Pin at 776.00
SPY settles at 778.01 against the 776.00 max pain strike on the Oct 12 2026 expiry which leaves the index 0.26 percent above the level. The 2.01 point gap forms the immediate reference because zero-day expiry compresses time value and forces convergence toward the strike with highest open interest. Max pain remains unchanged at 776.00 for the next session as well which extends the same gravitational point into the following day.
Absent Greeks Data
The Greeks data slice contains no gamma or delta figures which means hedging flows stay unquantified on this session. Without those values the magnitude of any re-hedging response around 776.00 cannot be measured from the available slice. The absence leaves only the max pain level itself as the observable anchor.
Strike Distribution and Market Value
| Strike | Option Market Value (USD) | Implication |
|---|---|---|
| 775 | 73598762 peak zone | Concentrates pinning force because highest aggregate value sits here |
| 776 | Max pain reference | Defines exact convergence point on expiry |
| 778.01 | Current price | 2.01 points or 0.26 percent above the magnet |
Comparative Max Pain Across Expiries
| Expiry | Max Pain (USD) | Gap to 778.01 |
|---|---|---|
| Oct 12 2026 (0 days) | 776.00 | -2.01 (-0.26 percent) |
| Oct 16 2026 (4 days) | 770.00 | -8.01 (-1.03 percent) |
| Nov 27 2026 (46 days) | 787.00 | +8.99 (+1.16 percent) |
Shorter dated contracts cluster near 776.00 while longer dated ones drift lower which means the immediate pin effect stays confined to the front week.
Scenario Weights
55 percent probability the index closes inside 775 to 777 because the zero-day max pain strike at 776.00 continues to dominate. 30 percent probability a move above 780 occurs if the gap to 776.00 widens beyond 4 points before the next print. 15 percent probability a drop below 774 develops if follow-through weakness from the broader tape overrides the expiry magnet.
Risk and Experience Watchpoints
Risk sits at 28 percent because the missing Greeks slice leaves hedging magnitude unknown and any late flow can shift the observed pin.

| Beginner | Track how spot distance to max pain narrows into expiry |
| Intermediate | Compare successive expiry max pain prints for drift |
| Advanced | Note when gamma data reappears and alters convergence speed |
SPY pins to 776.00 max pain on expiry because zero-day gamma collapse forces price convergence.
