๐ค What This Actually Means
This is a tactical profit-taking and repositioning trade executed with military precision! Here's the play-by-play:
The Profit Take: ๐
- Sold 4,240 contracts of $170 calls for $13M
- These are deeply in-the-money (ITM by $13.69)
- Cashing out realized gains from earlier positions
The Bullish Repositioning: ๐
- Bought $185 calls for $5.3M (heaviest new position)
- Bought $210 calls for $2.6M (lottery tickets!)
- Bought $175 calls for $1.2M
Strategic Message: This trader believes SNDK continues higher but wants to:
1. Lock in profits from the massive 180% YTD rally
2. Reduce position size but maintain upside exposure
3. Position for the $185-$210 range post-earnings
Unusual Score: ๐ฅ EXTREME (7,941x average size) - This is the kind of trade that happens maybe once or twice a year! We're talking about activity that's 7,941 times larger than normal - approximately 100th percentile territory. Real talk: this is institutional-level positioning that retail almost never sees.
๐ Technical Setup / Chart Analysis
YTD Performance Chart
SNDK has been on an absolute moonshot in 2025! After spinning off from Western Digital in February, the stock has surged over 180% year-to-date and climbed more than 100% in October alone. ๐
Key Observations:
- Historic Rally: From ~$60 lows to current $183.69 - nearly a triple!
- Momentum Explosion: October saw unprecedented acceleration
- Fresh Highs: Just hit new all-time highs ahead of November 6th earnings
- Volume Surge: Massive institutional accumulation visible
- AI Storage Thesis: Market pricing in the explosive AI data center demand
The chart shows a classic growth stock breakout pattern with strong support building at each level as it climbs. This isn't random - it's driven by fundamental catalysts in the AI infrastructure boom.
Gamma-Based Support & Resistance Analysis
Current Price: $184.87
The gamma landscape reveals critical battle zones where options positioning creates natural price magnets:
๐ก๏ธ Major Support Levels:
- $180 - The Fortress (0.98M GEX, 2.6% below)
- Strongest gamma support level with 0.91M net call GEX
- Massive open interest concentration here
-
Acts as first line of defense on any pullback
-
$175 - Secondary Defense (0.36M GEX, 5.3% below)
- Solid call gamma wall providing cushion
-
Notice the $175 call buying in the option tape? That's reinforcing this level!
-
$170 - Deep Support (0.63M GEX, 8.0% below)
- Ironically, this is where institutions just sold calls
-
Still strong support from remaining open interest
-
$165 - Put Wall (0.37M GEX, 10.7% below)
- First level with negative net GEX (put-heavy)
- Would provide bounce support if market corrects
๐ Resistance Levels:
- $185 - Immediate Ceiling (0.62M GEX, 0.1% above)
- Currently testing this level RIGHT NOW
- Heaviest call buying was at this strike ($5.3M)
-
Breaking above $185 confirms bullish continuation
-
$190 - Next Target (0.52M GEX, 2.8% above)
- Natural profit-taking zone
- If earnings deliver, this gets tested quickly
Net GEX Bias: BULLISH โ
- Total Call GEX: 5.09M
- Total Put GEX: 2.33M
- Net Bias: +2.76M (heavily skewed to calls)
What This Means: Market makers are positioned for upside. As SNDK rallies, MMs need to buy more stock to hedge their short call exposure (gamma hedging), which creates a feedback loop pushing prices higher. The $180-$185 zone is the current battleground, with major support below and clear runway to $190+ if earnings catalyst hits.

๐ฒ Price Targets & Probabilities
Based on gamma levels, catalyst timing, and current technical setup:
๐ Bull Case (40% chance)
Target: $210-$230
Catalysts:
- Earnings beat with strong guidance for BiCS8 ramp and cloud segment
- HBF development update accelerates timeline expectations
- Memory pricing continues upward trajectory into 2026
- AI data center demand exceeds already-elevated expectations
Why it works:
- $210 strike had $2.6M in buying - lottery tickets that pay if this hits
- Breaking $190 resistance opens up air pocket to $210+
- Last quarter's 341% earnings beat shows surprise potential
- October momentum (+100%) suggests paradigm shift in market perception
- Energy storage analogy: SNDK to AI is what Tesla's energy segment became (surprise upside driver)
Gamma dynamics: Above $190, minimal resistance until $210 - fast move possible
๐ Base Case (45% chance)
Target: $175-$195
Scenario:
- Solid earnings beat but guidance conservative on BiCS8 timing
- Stock consolidates after massive October rally (+100%)
- Takes profit at $185-$190 resistance, finds support at $180
- Awaits Q2 results to confirm sustained AI data center demand
Why it's likely:
- Current price $184.87 sits right in middle of this range
- Strongest gamma support at $180 creates natural floor
- $185 call buying ($5.3M) suggests traders expect range-bound action here
- Profit-taking natural after 180% YTD gain
- Market may need to digest gains before next leg up
Perfect scenario for: The $175 and $185 call buyers - both strikes profitable
๐ฐ Bear Case (15% chance)
Target: $160-$175
Risks:
- Earnings disappoint on BiCS8 ramp delays or margin pressure
- Broader memory sector correction if demand signals weaken
- Valuation concerns after tripling in 2025 - profit-taking cascades
- Competition from Samsung/SK hynix intensifies in enterprise SSDs
Why it could happen:
- Stock up 180% YTD - vulnerability to "sell the news" on earnings
- EPS rating low (6 out of 99) reflects historical earnings volatility (Investors.com)
- Memory markets historically cyclical with boom-bust patterns
- Recent quarters showed negative net income, profitability still improving
Support levels: $175 (0.36M GEX), $170 (0.63M GEX), $165 (0.37M GEX)
Note: Only 15% probability because the $13M profit-taking at $170 strike suggests institutions expect to sell ABOVE that level, not below it. Bears would need multiple negative catalysts.
๐ก Trading Ideas
๐ก๏ธ Conservative: Follow the Smart Money (Defined Risk)
Play: Bull call spread (Nov 21st expiration)
Structure:
- Buy $180 calls (near money)
- Sell $195 calls (above resistance)
Max Risk: ~$8-10 per spread (limited to debit paid)
Max Reward: ~$5-7 per spread ($15 wide spread minus debit)
Breakeven: ~$188 (buy strike + debit paid)
Why this works:
- Strongest gamma support at $180 protects downside
- $185-$195 zone is where institutions repositioned
- Captures earnings catalyst with defined risk
- Time decay works in your favor if stock stays range-bound initially
Best for: Traders who want exposure but can't stomach the volatility
โ๏ธ Balanced: Replicate the Institutional Trade (Moderate Risk)
Play: Buy $185 calls straight (Nov 21st)
Risk: Premium paid (~$24-26 per contract = $2,400-2,600 per contract)
Reward: Unlimited above breakeven
Breakeven: ~$209-211 ($185 strike + premium paid)
Why this works:
- Institutions dropped $5.3M on this exact strike - the biggest new position
- At-the-money positioning with 28 days to expiration captures earnings Nov 6th
- Implied volatility elevated but justified given catalyst potential
- $185 is current resistance - breakthrough confirms bullish continuation
Position sizing: Risk 2-3% of portfolio maximum given volatility
Best for: Traders comfortable with options volatility who believe in the AI storage thesis
๐ Aggressive: Lottery Tickets with Asymmetric Payoff (High Risk)
Play: Buy $210 calls (Nov 21st)
Risk: Premium paid (~$15-16 per contract = $1,500-1,600 per contract)
Reward: Multi-bagger potential if stock explodes post-earnings
Breakeven: ~$225-226 ($210 strike + premium)
Why this could work:
- Institutions bought $2.6M of these - they're expensive lottery tickets for a reason!
- Only needs 14% move from current price ($184 to $210)
- October alone saw 100%+ move - momentum is real
- Last quarter delivered 341% earnings surprise - precedent for explosive moves
- HBF news or BiCS8 ramp acceleration could be game-changer
The case: If SNDK beats and guides aggressively (cloud to 20% of revenue, BiCS8 to 50%+ of mix), this could hit $230+ making these 4-5x winners
Reality check: This is a binary bet - either hits big or expires worthless. Only allocate "Vegas money" you can afford to lose completely.
Position sizing: Absolute maximum 1% of portfolio - treat like a call option should be treated (speculation)
Best for: Risk-tolerant traders who want leveraged exposure and can handle 100% loss
โ ๏ธ Risk Factors
Let's be real about what could derail this trade:
Fundamental Risks
- Valuation stretched: Up 180% YTD - much optimism already priced in (Yahoo Finance)
- Profitability concerns: Recent quarters showed negative net income, still recovering (StockAnalysis)
- Earnings volatility: Low EPS rating (6/99) reflects inconsistent results (Investors.com)
- Cyclical industry: Memory markets historically boom-bust - sustainability questions
Execution Risks
- BiCS8 ramp delays: Technology transitions can hit snags
- HBF commercialization: 2026-2027 timeline is aspirational, not guaranteed
- Competition: Samsung, SK hynix, Micron, Seagate all fighting for market share
- Margin pressure: If NAND pricing stabilizes instead of rising, margins compress
Market Risks
- Broader correction: If tech sector pulls back, SNDK follows
- IV crush: Options pricing in big move - if stock stays flat post-earnings, premium evaporates fast
- Profit-taking: After 100% October rally, natural consolidation likely
- Timing risk: Nov 21st expiration gives only 15 days post-earnings - limited time for thesis to play out
Options-Specific Risks
- Liquidity: While improving, SNDK options can have wide bid-ask spreads during volatile periods
- Assignment risk: Short legs in spreads could get assigned if stock moves sharply
- Gamma risk: Being long gamma helps if stock moves, but time decay accelerates if it stays flat
Bottom line: This isn't a free lunch. The unusual score is extreme BECAUSE it's an extreme bet. Size your positions accordingly and have an exit plan for both winners and losers.
๐ฏ The Bottom Line
Real talk: This $22.1M synchronized option trade is institutional money making a calculated bet on SNDK's AI storage boom continuing through November earnings and beyond.
The message is clear:
1. Take profits - Selling $13M of $170 calls locks in gains from the massive rally
2. Stay long - But buying $9.1M of higher strikes ($175, $185, $210) shows conviction continues
3. Target $185-$210 - This is where smart money expects the stock post-earnings
If you own SNDK: Consider trimming at $190-$200 to lock in some gains, but this trade suggests institutional support for higher prices
If you're watching: November 6th earnings is your catalyst. The gamma setup shows strong support at $180 and clear runway to $190+
If you're bullish: The November 21st options perfectly capture the earnings event with two weeks of follow-through. Pick your risk level and size accordingly.
Mark your calendar: ๐
- November 6, 2025 (After Market Close): Q1 FY2026 earnings - this is the game
- November 21, 2025: Option expiration - clock is ticking on this trade
The lesson: When institutions drop $22M positioning for a specific catalyst with precision timing, pay attention. They're not always right, but they usually have information advantages. The AI data center theme is real, BiCS8 is ramping, and SNDK is positioned at the epicenter of the memory supercycle.
Just remember - up 180% YTD means a lot of good news is priced in. Earnings need to EXCEED already-elevated expectations for another leg up. Trade accordingly. ๐
