The Reload

How the pin rebuilt in seven sessions, stalled forty points under the June top, and rolled off at July expiration

8-part reconstruction of July 1–17: two dead-flat closes to open the month, then a call-led rebuild (walls migrating $7,630 → $7,700, measured VIX floor 14.96), the end of the US–Iran ceasefire flushed to $7,421 and reclaimed inside a session, a CPI relief pop to a $7,581 window high 39 points under the June top, and the roll-off into the July 17 monthly settlement on a book that had inverted to 71% puts. The gamma sign flipped five times in ten sessions: neither the damper of May nor the amplifier of June, but an alternator. Includes two corrections to the June paper.

The Expiry

How the long-gamma pin finally rolled off, and June round-tripped $7,600 to $7,238 and back

8-part reconstruction of June: a low-vol top at $7,620 on a book already turned net-short gamma, the May-jobs crack on June 5 (−2.64%), the negative-gamma flush to an intraday $7,238, the FOMC break, and the late-June decay regime as the walls compressed toward spot on a thinning near-money book. The dealer book rotates pinned → expand → decay; the pin the prior three papers kept flagging finally expires. Per-session SPX tables, wall structure, and full methodology. (Two figures corrected July 18, 2026; see the editor’s note in the paper.)

The Pin That Climbed

How a long-gamma dealer book survived its two flagged tests and migrated three hundred points higher

8-part reconstruction of the May 9–29 window: the April CPI print absorbed on the upside (May 13, +0.56% to $7,444), the monthly OPEX push through $7,500 (May 14), the lone post-expiry gamma-off day, the mid-month dip that held at the rebuilt put wall, and the grind to a $7,579 close on the most compressed volatility of the entire rally. Per-session SPX tables, call-wall migration from $7,400 to $7,750, and full methodology.

The Test the Rally Passed

Three weeks above $7,000 and the first downside catalyst that didn’t break the structure

On April 21 the S&P 500 dropped 85 points intraday, the largest single-session decline since the V. By Friday April 24 it printed a new all-time closing high. Across the next two weeks vol compressed from 19 to 17 and the index advanced another 3.83% on six new closing records. This is what the options market did during a quiet period that wasn’t supposed to be quiet.
