Opened a DRAM calendar call spread at the $70 strike — short the Dec 18 '26 70C, long the Jan 15 '27 70C — on continued DRAM weakness. Opened July 24, 2026, 11:12 AM ET at $1.075 debit ($107.50 total; 1 calendar spread). Defined-risk theta-harvest structure; estimated max profit ~$628.38 if DRAM reclaims $70 by the Dec 18 front expiry, max loss $107.50 (= debit). Profit zone approximately $68–$72 at front expiry. Spot $54.25 at entry; IV ~94% (front 95.28%, back 93.54%).
Why This Structure
The calendar call spread is a defined-risk theta-harvest structure: short a near-dated call, long a further-dated call at the same strike. The front short leg decays faster than the back long leg, so the spread gains value as time passes — provided the underlying stays near the strike.
Why a calendar instead of a diagonal? The earlier DRAM diagonal (Jul 15) used different strikes across expiries to express a directional recovery view. The calendar uses the same $70 strike on both legs — a purer volatility/theta expression. With DRAM sold off to $54.25 (22.5% below the $70 strike), the calendar doesn't need a directional call: it needs DRAM to drift back toward $70 by December and then sit still.
Why the $70 strike? $70 is the round-number magnet — the level DRAM traded at before the selloff, and the strike with the deepest liquidity on both expiries. A calendar's max profit concentrates at the strike at front expiry; placing it at the pre-selloff level aligns the structure's peak with the recovery target.
Why 28 days between legs? The Dec 18 → Jan 15 gap (147 DTE front, 175 DTE back) is wide enough that the back leg retains meaningful time value when the front expires — the calendar's residual value is the trade's second profit engine if DRAM hasn't reached $70 by December.
Thesis
- Selloff recovery to a magnet level: DRAM has sold off to $54.25 on sector weakness. The $70 strike is the pre-selloff trading level and a natural magnet. The calendar's estimated max profit of ~$628 concentrates exactly there at the Dec 18 front expiry.
- Extreme IV favors selling front premium: IV ~94% (front 95.28%, back 93.54%) prices enormous expected movement. The calendar sells the richer front-month premium ($8.175 live mid on the short Dec 70C) against the slightly cheaper back month — harvesting the term-structure edge while staying defined-risk.
- Two ways to win: If DRAM reclaims $70 by Dec 18, the front short expires worthless against a still-valuable back long — the ~$628 peak. If DRAM stays depressed, the back leg's residual time value plus the front leg's faster decay still leaves salvage value; the structure can be rolled or closed for a partial recovery.
- Defined risk on a volatile single name: A 94%-IV underlying can gap violently. The calendar's max loss is the $107.50 debit — no matter how far DRAM runs in either direction, the long back leg caps the damage.
Risk
| Risk | Magnitude | Mitigation |
|---|---|---|
| DRAM stays below ~$68 at Dec 18 expiry | Partial to full loss of the $107.50 debit | Close 7 days before short expiry; roll the back leg if the recovery thesis is intact |
| DRAM rips above ~$72 before Dec 18 | Calendar loses value as both legs go deep ITM and the spread compresses | Stop at $215 cost to close (2× debit); the long back leg caps the loss |
| DRAM below $50 at any point | Recovery thesis broken | Hard stop: close the structure if DRAM closes below $50 |
| IV crush on a snapback | A violent rally crushes IV; the back long leg loses vega value | The short front leg benefits more from IV crush than the long back leg loses — net favorable |
| Earnings gap | Single-name gap risk in either direction | Defined risk: max loss $107.50 regardless of gap size |
Position Payoff at Three Time Horizons
The chart shows the P/L curve at three time horizons. The calendar's signature tent shape peaks at the $70 strike at the front (Dec 18) expiry — the estimated ~$628.38 max profit if DRAM closes exactly at $70 on Dec 18. The profit zone is narrow (approximately $68–$72): calendars are precision structures, not wide-net structures. As time passes toward the front expiry, the tent sharpens; the back leg's residual value is the floor under the position.
Key levels on the chart:
- Spot $54.25 — current underlying price, 22.5% below the strike.
- Strike $70.00 — both legs; the calendar's peak at front expiry.
- Max profit ~$628.38 — at $70 on Dec 18, 2026 (BSM estimate).
- Max loss $107.50 — the net debit, realized if DRAM is far from $70 at front expiry.
- Profit zone ~$68–$72 — approximate breakeven band at front expiry (source estimate).

Greeks Snapshot (Black-Scholes)
| Greek | Interpretation |
|---|---|
| Delta (Δ) | Near-zero at entry with spot far below the strike; delta grows as DRAM approaches $70. |
| Gamma (Γ) | Long gamma near the strike at front expiry — the tent's peak is a gamma concentration. |
| Theta (Θ) | Net positive — the front short leg decays faster than the back long leg. Time is the trade's edge. |
| Vega (ν) | Net short vega on the front leg vs long vega on the back; a parallel IV crush helps the structure. |
Numbers per-contract = per-share × 100.
Verification (anti-pattern #80: basis vs live)
Live verification against the chain at entry:
| Leg | Recorded basis | Live mid |
|---|---|---|
| Short Dec 70C | $7.80 | $8.175 |
| Long Jan 70C | $8.875 | $9.10 |
| Net debit | $1.075/share ($107.50) | $0.925/share ($92.50) |
The live chain was $0.15/share tighter than the recorded basis — a $15/contract saving. The source records the $1.075 basis for the hero numbers; the live economics are modestly better.
How the Trade Has Moved Against the Underlying
The source includes a companion spot-vs-strategy-premium simulation chart (not migrated; only the P/L curve was in scope). Its key reading: the calendar's premium is a tent centered on $70 — the structure gains value fastest as DRAM grinds toward the strike and loses value on sharp moves away from it in either direction. With spot starting at $54.25, the position needs a sustained 29% recovery rally to reach its peak.
Intraday Setup (entry)
- Pre-market context: Continued DRAM weakness; spot $54.25 at entry. IV ~94% reflects the market pricing large moves in both directions.
- Entry signal: The $70 strike sits 29% above spot — the pre-selloff level and the natural recovery magnet. The 28-day calendar width gives the back leg meaningful residual value at front expiry.
- Execution: Opened July 24, 2026, 11:12 AM ET at $1.075 debit (recorded basis). Live-mid cross-check: $0.925 — the actual fill economics were ~$15/contract better than the recorded basis.
- Position size check: $107.50 max loss = 0.036% of $300k book. Well below the per-trade cap.
Management Plan
- Profit target: $314 — 50% of the ~$628 estimated max profit. Take it if the calendar's mark reaches the target; calendars rarely need to be held to the exact peak.
- Time stop: Close 7 days before the short leg's expiry (around Dec 11) regardless of P&L. Never hold a short front leg into expiry week on a 94%-IV single name.
- Stop loss: $215 cost to close (2× the debit) OR DRAM closes below $50 — the recovery thesis is broken at that level.
- Adjustment: If DRAM approaches $70 well before December, consider taking the profit early rather than nursing the tent. If DRAM is still depressed in late November, roll the structure or close for salvage.

Lessons
(To be filled in as the trade progresses through Q3/Q4 2026.)
- For the playbook: A 28-day calendar on a 94%-IV single name is a non-standard duration/IV bucket. The playbook's calendar section calibrates shorter-dated structures; a note on wide-interval calendars on high-IV underlyings would be useful.
Cross-references
- The 2026-07-15 DRAM diagonal call spread (this journal) is the predecessor structure — a directional recovery expression that the calendar refines into a purer theta/volatility trade.
- The playbook (2026-07-05 SOP) governs the 50%-of-max-profit take-profit rule and the 7-day pre-expiry close discipline used here.
