GOOG Calendar Spread — 2026-10-09

GOOG (Alphabet Inc. - Class C Capital Stock): $1020K of buyer-initiated unusual call flow (100% call-dominant), IV rank 22 (low). Our gamma model reads GOOG in a POSITIVE-gamma regime (net GEX 4.8M, flip —) — dealers are long gamma and suppress realized vol, so price tends to pin/mean-revert between the $335 put wall (support) and $340 call wall (resistance). Structured as a Calendar Spread (sell $340C / buy $340C) expiring 2026-10-09 (24 DTE) — positive-gamma pin at wall → sell near-dated theta (calendar). Net debit $157 (max risk). Breakevens $340.00.

Underlying: GOOG @ ~$341.15 | 2026-10-09 (24 DTE) | Net debit (entry): ~$157 per spread. Use limit orders at the mid or slightly better.

ENTRY: Buy the calendar at $340: SELL the near-dated 2026-10-09 option, BUY the same-strike far-dated option, one order at a LIMIT of the mid or better — net DEBIT ~$157. Best when spot is pinned at $340 in a positive-gamma regime and near-term IV is LOW relative to the back month (you want front-month theta plus room for a vega/IV expansion). Gamma: dealer gamma is POSITIVE (vol-suppressing) — spot tends to pin/mean-revert, so a briefly-tested strike often reverts; don't over-adjust on the first touch; put wall (support) at $335; call wall (resistance) at $340. IV rank 22 is low — premium is thin, so keep size small and lean on a defined-risk structure. | TAKE PROFIT: This is a DEBIT trade — take profit as the NEAR leg decays and/or IV EXPANDS, typically ~20–35% on the $157 debit. EXIT BEFORE the near (short) leg's 2026-10-09 expiration — never let the short leg expire or go in-the-money; roll the short out or close the whole calendar around 22 DTE on the front leg. | IF TESTED: A calendar wants spot to STAY near $340; it loses if GOOG runs away from the strike (both legs go deep ITM/OTM and the spread collapses). If price drifts off $340 by more than about the width you paid, ROLL the whole calendar's strike toward price (a diagonal roll) to re-center, or cut it — don't defend a directional runaway with a neutral structure. Treat a close below the $335 put wall as the hard trigger to act (the pin support has failed); Treat a close above the $340 call wall as the hard trigger to act (the resistance magnet has broken). Max loss is the $157 debit paid. | MAXIMIZE: If GOOG pins $340 and near-term IV stays low while the back month firms, let the front leg decay for the biggest gain, then roll the short leg out to a new near-dated expiration to collect another cycle of theta (turning it into a longer campaign) — but always close before the current short leg expires.
