SNDK less signal strength from options side -> but there could be a pattern from OPEX now
Live: Spot $1,406.99 (+1.76% today) — and May 15 Weeklies Have Expired
The expiration of the May 15 weekly options has significantly altered the market's structural landscape:
Friday OPEX Decay in Action
| Metric | Thu 05/14 15:55 | Fri 05/15 15:55 | Change (Δ) |
|---|---|---|---|
| Spot | $1,382.89 | $1,406.99 | +$24 (+1.8%) |
| Net Dealer GEX | -$0.26M | -$0.34M | Slightly lower |
| Gamma Flip | $1,382 | $1,309 | -$73 |
| Buffer | +0.1% | +7.5% | Expanded 74x |
| Min-$\gamma$ Strike | $1,470 | $1,912 | +$442 (further away) |
| Min-$\gamma$ Magnitude | -$2.35M | -$1.23M | -48% |
| Max-$\gamma$ Strike | $1,202 | $1,062 | -$140 (further away) |
| Max-$\gamma$ Magnitude | +$2.50M | +$0.45M | -82% |
| Expiry Count | 19 | 18 | May 15 off the board |
This is the exact mechanism I outlined in the forecast 8 days ago:

Today marks the fifth consecutive confirmation of this pattern.
To be specific: The May 15 Calls at $1,450, $1,500, and $1,600 have just settled. With their exit, the densest short-gamma ($\gamma$) cluster has been wiped out. The May 15 Puts at $1,200–$1,300 are also gone, meaning the long-gamma anchor has lost 82% of its magnitude.

Notable Patterns:
- Dramatic Buffer Spikes on Friday OPEX: On both May 8 and May 15, the buffer surged sharply—jumping to +42.7% on the 8th, and to +7.5% today from yesterday's razor-thin +0.1%.
- Mid-Week Compression: Between Fridays, the buffer compresses significantly due to new Open Interest (OI) rebuilding.
- Shifting Min-$\gamma$ Strike: The Min-$\gamma$ strike takes massive leaps during each OPEX week: $1,491 $\rightarrow$ $1,620 $\rightarrow$ $1,470 $\rightarrow$ $1,912.
Current Structural Situation
We are currently sitting in a "hollowed-out" profile between two weak anchors:
- Min $\gamma$ (Resistance): $1,912 (-$1.23M) | +35.8% from Spot
- Current Spot: $1,407
- Flip: $1,309 | -7.5% from Spot
- Max $\gamma$ (Support): $1,062 (-24.5% from Spot, +$0.45M)
The mechanical anchoring effect is quantitatively minimal right now:
- Min $\gamma$ is 36% away: Before the spot price feels any structural pull from it, a new wave of OI would need to build up at closer strikes.
- Max $\gamma$ is 24.5% away: With a magnitude of just +$0.45M, this support anchor is remarkably weak.
- The Flip Level sits 7.5% below spot: This remains the only meaningful structural level in our immediate vicinity.
Trading Implications
Yesterday's "mean-reversion sandwich" has broken apart. While the range has expanded, the structural "walls" are much weaker. Statistically speaking:
- No clear mechanical edge: The structural advantage for short-term traders has dissolved for now.
- Fundamental/News-driven phase: Price action is currently vulnerable to pure news catalyst momentum rather than options market gravity.
- Attractive Vol-Compression Trades: Wide Short Strangles around the spot price look appealing because there are no immediate mechanical stops nearby to trigger sharp, forced hedging moves.
Specific Levels to Watch:
- $1,309 (Flip Level): The only nearby mechanical level. A break below this activates the short-vol, long-gamma regime, though the Max-$\gamma$ anchor at $1,062 remains weak (just +$0.45M).
- Above $1,450: No squeeze tailwinds here. This would be a pure momentum/trend trade.
- $1,912: Nominally the next magnet strike, but being +36% away, it won't be relevant anytime soon.
Setup Evaluation:
- If Long: Place a stop below $1,310, with a re-entry trigger above $1,470 (previous structural resistance).
- If Short: The hurdle for a direct short is high, given that the Flip level sits relatively deep below current spot.
- If Flat: Wait for the next OI rebuilding phase on Monday/Tuesday, then re-analyze the GEX structure.
What This Means for Your Time Series
With 10 data points collected—including two Friday OPEX days—even this small sample size clearly illustrates the periodic decay-and-rebuild pattern:
| Phase | Observation |
|---|---|
| Pre-OPEX (Thu-Fri) | Buffer compresses to <5%, establishing the tightest concentration of risk. |
| Friday OPEX | Buffer jumps to +7.5% to +42% as anchors thin out and underlying mechanics discharge. |
| Mon-Wed | Buffer re-compresses as fresh weekly and monthly open interest is established. |
| Crash/Trend Days | The Flip level moves lockstep with Spot, keeping both sides of the GEX profile highly reactive. |
If this pattern holds up robustly over the next 3 to 4 OPEX cycles, you will have empirically documented a clear weekly seasonality in SNDK GEX. Genuinely, this is the single most actionable strategy idea to come out of this entire analysis: executing an OI Decay Trade leading into every Friday, followed by a Rebuild Long positioning play on Monday or Tuesday.
Practical Takeaway: It is Friday close, the market setup is mechanically discharged, and there is no high-probability setup on the board. Let's enjoy the weekend, pull fresh data on Monday morning, and see where the new week kicks off structurally. That will give us our 11th data point in this evolving pattern.
