Complete Flow Summary

The Top 5 Trades You Need to Know

1. SNDK -- $22M Deep ITM Call Buy, 2 Days Before Earnings

SEE WHY AN INSTITUTION PAID $22M FOR LEVERAGED EXPOSURE TO THE BEST S&P 500 STOCK

An institution bought 498 contracts of the $50 call (stock at $488.81) -- a near-perfect stock replacement controlling $24.3M in notional exposure. SanDisk is up 860% since its February 2025 spinoff from Western Digital, driven by AI-fueled NAND demand and a 27.5% single-day pop after Jensen Huang's CES 2026 comments. Earnings hit Wednesday at 1:30 PM Pacific, with NAND prices projected to rise 33-38% QoQ.

• Expiry: March 20 (Quarterly Triple Witch)
• Catalyst: Fiscal Q2 earnings January 29 -- then BiCS8 production milestone by June
• The risk: Trading at 26.5x forward P/E (memory peers at <10x) and 37% above average analyst target of $357.53

2. IWM -- $13.1M Bull Put Spread, 7 Days to FOMC + GDP

DECODE THE $13.1M BET THAT SMALL CAPS HOLD THROUGH THIS WEEK'S MACRO GAUNTLET

A trader executed a $265/$263 bull put spread with BELOW-BID urgency, collecting a $1.9M net credit. The bet: IWM stays above $265 through February 5 while FOMC holds rates (97% probability) and GDP data confirms economic resilience. The Russell 2000 just posted a historic 15-session outperformance streak vs the S&P 500 ("Great Rotation").

• Expiry: February 5 (Weekly -- 7 trading days)
• Catalyst: FOMC January 28 (tomorrow) + Q4 GDP January 29
• The risk: Hawkish Fed surprise would hit rate-sensitive small caps hardest; Goldman says consensus EPS growth of 61% is "far too optimistic"

3. UNH -- $10.7M Bear Call Spread on 20% Crash Day

UNDERSTAND WHY $3.3M IN PREMIUM WAS COLLECTED ON UNH'S WORST DAY IN A DECADE

On the same morning UNH crashed 20% after reporting its first revenue decline in a decade and receiving near-flat Medicare Advantage rates (0.09% vs expected 4-6%), an institution placed a $330/$360 bear call spread collecting $3.3M. Both strikes are above the crash price -- the bet is that UNH does NOT recover to pre-crash levels by May.

• Expiry: May 15 (Monthly -- 108 days)
• Catalyst: CMS finalizes 2027 MA rates in early April -- the swing event
• The risk: CMS final rates at 2-3% would trigger a 15-20% sector rally; DOJ investigation wildcard

4. META -- $5.7M Call Buy, Hours Before Q4 Earnings

SEE THE $5.7M BET TARGETING META'S BIGGEST GAMMA LEVEL BEFORE TOMORROW'S EARNINGS

A trader paid $22/contract for 2,598 contracts of the $700 call -- placed this morning, hours before META reports Q4 earnings tomorrow after close. The $700 strike sits at the single largest gamma concentration on the options board (28.9B total gamma). Consensus expects $58.45B revenue (+21% YoY). The swing factor: 2026 capex guidance (above $100B with unclear AI ROI could sell off).

• Expiry: February 27 (Monthly -- 31 days)
• Catalyst: Q4 earnings TOMORROW January 28 after close
• The risk: 5.76% implied weekly move; capex above $100B with unclear ROI triggers selloff; FTC appeal filed January 20

5. VSAT -- $3M Double Call Buy Before Earnings + Spin-Off Catalyst

DISCOVER THE 429x Z-SCORE TRADE ON VIASAT'S DEFENSE SPIN-OFF CATALYST

Two trades fired one second apart: 3,600 contracts each at the $42 and $48 strikes. The $48 strike had only 73 contracts of open interest before this trade (Z-score: 429.35). VSAT is up 330% from its 52-week low, fueled by Morgan Stanley's 325% PT raise to $51 and activist Carronade Capital arguing the defense unit alone is worth $50+/share.

• Expiry: February 20 (Monthly -- 24 days)
• Catalyst: Q3 earnings ~February 5-10 + DAT division spin-off decision
• The risk: $5.5B net debt; CEO sold $11M in shares; Starlink competition (72% market share, 20-50ms vs 600ms+ latency)

Also on the Radar

CRWV ($11.5M) -- CoreWeave position rotation: closing $7M in winning trades and reloading $4.5M fresh -- $130 March calls + selling $180 June ceiling. NVIDIA just invested $2B at $87.20/share. Earnings February 18. Implied move: +/-17.21%.

EEM ($8.4M) -- Someone paid $8.4M to close a LEAP short call at $65 on the Emerging Markets ETF. When a trader buys back a short call early instead of collecting remaining premium, it means they respect the rally. SCOTUS tariff ruling expected January-February could be the catalyst.

MARA ($2.4M) -- $2.4M March $10 call buy on the largest Bitcoin miner, trading near 52-week lows. Bitcoin holdings ($4.7B) exceed market cap ($3.8B) -- a NAV discount with 36.2% short interest as squeeze fuel. Fed decision tomorrow is the near-term catalyst.

PFE ($1.2M) -- Cheap lottery ticket: $0.45/contract on a deeply oversold $147B pharma giant with 6.65% dividend yield. Two FDA approval dates (Padcev April 7, vepdegestrant June 5) and earnings February 3 create multiple shots on goal.

FSLY ($1.1M) -- A LEAP call SELL collecting $2.13/share (20.6% of stock price) for a full year. Betting Fastly stays stuck below $12.50 while Cloudflare eats its lunch at 40% CDN market share. Earnings February 11.

Your Action Plan by Investor Type

YOLO Trader (1-2% portfolio max per position)

Binary outcomes, asymmetric payoff, accept 100% loss

SNDK earnings gamble -- Options pricing an 11% post-earnings move on a stock already up 860%. If AI storage guidance doubles, near-term calls could 3-5x. If guidance disappoints at these valuations, total wipeout.

META earnings coin flip -- $5.7M is riding on tomorrow's report. The $700 gamma magnet level could trigger a squeeze toward $720-$750 on a beat. Capex above $100B kills it.

MARA Bitcoin squeeze -- 36.2% short interest + NAV discount on a name trading near 52-week lows. If Bitcoin bounces post-FOMC and shorts cover, the move could be violent.

Exit strategy: Take 100%+ gains immediately. Scale out at 50%, 100%, 200%. These are not investments.

Swing Trader (3-5% portfolio, 2-8 week holds)

Institutional-backed momentum with defined catalysts

CRWV into February 18 earnings -- Follow the institutional rotation. They closed winners and reloaded March $130 calls after NVIDIA's $2B investment. Ride the momentum into earnings.

VSAT into Q3 earnings + spin-off -- $3M double-barrel call buy with activist pressure for a defense unit spin-off worth $50+. Morgan Stanley PT at $51 vs current $44.63.

PFE 5-month catalyst runway -- Two FDA decisions + earnings on a deeply oversold name (RSI 21.6). Cheap entry with multiple shots on goal through June.

Risk management: Stop at 30% loss. Take 50% profits at 50% gain. Close before binary events if unsure.

Premium Collector (Income focus, sell high IV)

Follow institutional sellers, harvest time decay

FSLY model trade -- Copy the $1.1M LEAP call sale. Selling $12.50 calls for $2.13 (20.6% yield) on a range-bound stock with declining competitive position. If you own shares, this is a textbook covered call.

IWM bull put spread -- Follow the $13.1M whale. Selling $265/$263 puts into FOMC/GDP week collects premium on a 97% probability rate hold. 7-day theta burn.

UNH bear call spread -- The $3.3M credit collection on crash day. Selling $330/$360 calls above a broken stock that just guided for its first revenue decline. 108 days of theta decay in your favor.

Rules: Only sell premium on names you understand. Close at 50-60% max profit. Roll before expiration if losing.

Entry Level Investor (Learning first, small positions)

Build knowledge before scaling

Paper trade the IWM spread this week -- Watch how a bull put spread behaves through FOMC and GDP releases. Track how theta decay works over 7 days. This is the best live classroom available.

Study SNDK's earnings reaction -- The stock is priced for an 11% move. Watch what happens to option premiums before, during, and after the report. This teaches IV crush.

Read the UNH bear call spread -- Understand why someone collects $3.3M on a day the stock drops 20%. This is how professional premium sellers operate during volatility spikes.

If you want equity exposure: Consider META shares (not options) below $660 with a stop at $620 -- large-cap quality with earnings catalyst but without options complexity.

Critical rule: Do not trade options until you have watched at least 10 earnings cycles. Paper trade everything first.

Risk Warnings: What Could Go Wrong

For Bulls (SNDK, META, MARA, CRWV, VSAT, EEM, IWM, PFE): - FOMC delivers hawkish surprise tomorrow despite 97% hold probability - SNDK guidance shows AI storage demand peaking, not accelerating - META capex above $100B with murky ROI sends stock below $640 - Bitcoin drops below $80K (MARA goes to single digits) - EEM tariff ruling goes against emerging markets - Any geopolitical escalation (Taiwan, Middle East) hits risk assets

For Bears (UNH, FSLY): - CMS April revision comes in at 2-3% (UNH rallies 15-20%, bear spread destroyed) - FSLY announces major AI edge partnership, breaks above $12.50 - Broader market melt-up lifts all boats regardless of fundamentals

Universal Warning: These are sophisticated institutional strategies that may be part of larger hedged portfolios. We see one leg; they may have ten. Do not assume a $22M call buy means "SNDK is going up" -- it means one institution is positioned that way, and they have risk management systems you do not.

Position sizing is your best friend. Patience is your second best friend. FOMO is your worst enemy.

Options involve substantial risk and are not suitable for all investors. The unusual activity tracked here represents sophisticated institutional strategies that may be part of larger hedged portfolios not visible to retail traders. These positions represent past institutional behavior and do not guarantee future performance. Always practice proper risk management and never risk more than you can afford to lose completely. Entry level investors should paper trade extensively before committing real capital. Options can expire worthless, resulting in 100% loss of premium paid.
