🏢 SLG $25M Put Calendar Spread - Smart Money Rolling Protection on Manhattan's Largest Office Landlord!

📅 November 24, 2025 | 🔥 Unusual Activity Detected

🎯 The Quick Take

Someone just executed a $25 MILLION put calendar spread on SL Green Realty (SLG) this morning at 09:59:52! This sophisticated trade bought 5,600 contracts of December 2026 $65 puts for $13M while simultaneously selling the same number of May 2026 $65 puts for $12M - netting a $1M debit. With SLG trading at $45.25 and down 33% in the past three months, this institutional player is positioning for continued downside through 2026 while Manhattan's office market faces massive refinancing headwinds. Translation: Smart money is betting SLG stays under pressure for the next year!

📊 Company Overview

SL Green Realty Corp (SLG) is Manhattan's largest office landlord and a pure-play REIT on NYC commercial real estate:
- Market Cap: $3.12 Billion
- Industry: Real Estate Investment Trusts
- Current Price: $45.25 (near 52-week low of $42.92)
- Primary Business: Owns/manages 32 million square feet of Manhattan office space across 53 buildings
- Key Properties: One Vanderbilt (100% leased), One Madison Avenue, Park Avenue Tower (pending $730M acquisition)

💰 The Option Flow Breakdown

The Tape (November 24, 2025 @ 09:59:52):

Time Symbol Side Buy/Sell Type Expiration Premium Strike Volume OI IV Delta Vega Open/Close Strategy
09:59:52 SLG ASK BUY PUT $65 2026-12-18 $13M $65 5,600 1 - - - BTO Put Calendar Spread
09:59:52 SLG BID SELL PUT $65 2026-05-15 $12M $65 5,600 5,600 - - - STO Put Calendar Spread

🤓 What This Actually Means

This is a put calendar spread - a bearish trade structure betting on time decay and continued weakness! Here's the breakdown:

  • 💸 Long leg: Bought 5,600 Dec 2026 $65 puts for $22.45 = $13M outlay
  • 📉 Short leg: Sold 5,600 May 2026 $65 puts for $20.95 = $12M premium collected
  • 💰 Net cost: $1.50 per spread × 5,600 = $840K net debit (after receiving $12M and paying $13M)
  • 🎯 Strike positioning: $65 strike is 44% ABOVE current price of $45.25 - both legs deep in-the-money
  • ⏰ Time spread: 7-month gap between expirations (May vs December 2026)
  • 📊 Position size: Controls 560,000 shares worth $25.3M at current prices

What's really happening here:

The trader is making a sophisticated bet that SLG remains under $65 through 2026. By selling the near-term May puts, they're collecting $12M in premium to finance the December puts. This structure profits if:

  1. SLG stays below $65 through May 2026 - the short puts expire worthless, trader keeps $12M premium
  2. Volatility stays elevated - the December long puts retain value from time decay and vol premium
  3. Stock doesn't recover significantly - maintains bearish positioning through full year

Think of it like renting out a property (selling May puts for $12M income) to finance buying a longer-term insurance policy (December puts costing $13M). The $1M net cost is the "carry" for maintaining this bearish position for a full year.

Why this structure vs outright puts?

This is MUCH more capital-efficient than buying puts outright. Instead of spending $13M for downside exposure, they're only risking $1M net. It's a high-conviction bet that SLG faces prolonged headwinds, not just a quick dip.

Unusual Score: 🔥 EXTREME (5,599x average volume) - This represents virtually ALL open interest on the December 2026 $65 puts. The matching size on both legs (5,600 contracts each) confirms this is a single institutional trader executing a deliberate strategy, not random retail activity.

Strategy Classification: CUSTOM SPREAD (Medium Confidence) - Calendar spread structure with bearish directional bias, designed to profit from time decay and continued weakness through 2026.

📈 Technical Setup / Chart Check-Up

YTD Performance Chart

SLG has had a BRUTAL year - up +73.4% YTD at $79.63 from $45.92 start-of-year price, but that's misleading! The stock rallied from $45 to a peak of $80.90 by mid-year, then completely collapsed back down to current levels near $45.

Key observations:
- 🎢 Round-trip journey: Climbed from $45 → $80 (75% gain), then crashed back to $45 (44% decline from peak)
- 📉 Recent weakness: Down 33% in just the past 3 months (from ~$68 in late August)
- 📊 Max drawdown: Only 12.35% on paper, but that's because we're back near start-of-year levels
- 📈 Volatility: 37.3% annualized - this is a high-volatility REIT with big swings
- ⚠️ Failed breakout: Could not sustain gains above $75-80 range, showing weak momentum

The chart tells a story of hope followed by disappointment. SLG rallied hard in H1 2025 on Manhattan office market recovery optimism and strong earnings, but the momentum completely died as refinancing concerns and sector headwinds returned. We're now testing the lows again.

Gamma-Based Support & Resistance Analysis

Current Price: $44.90

The gamma exposure map shows significant option positioning that reveals where SLG is likely to gravitate:

🔵 Support Levels (Put Gamma Below Price):
- $42.25 - Deep support with moderate put gamma (floor from 52-week low $42.92)
- $44.50 - Immediate support near current price
- $45 - Secondary support with balanced gamma
- $47.50 - Higher support if stock bounces

🟠 Resistance Levels (Call Gamma Above Price):
- $45.50 - Immediate ceiling with call gamma cluster
- $47.75 - Secondary resistance zone (strong call gamma wall)
- $48 - Major resistance with MASSIVE call gamma concentration (strongest single level!)
- $50 - Extended resistance with huge call + put gamma positioning

What this means for traders:

SLG is currently trading at $44.90, caught between immediate support at $44.50 and resistance at $45.50-$48. The MASSIVE gamma concentration at $48 (both calls and puts) acts like a magnet - dealers will actively hedge around this level, creating natural resistance to moves beyond it.

The $50 strike shows enormous positioning on both sides - this is the key battleground level. Tons of call sellers at $50 (betting stock stays below) and put protection at $50 (insurance buyers). This creates a gravity well effect where price tends to stay range-bound.

Notice the trade setup? The put calendar spread is struck at $65 - way above the current gamma map. This isn't about near-term trading levels. The trader is positioning for a scenario where SLG remains weak (below $65) for an extended period, not making a short-term bet on $48 or $50 levels.

Net GEX Bias: Mixed/Bearish - Heavy put gamma below current price suggests defensive positioning, while call gamma resistance above shows limited upside expectations.

Implied Move Analysis

Options market pricing for upcoming expirations:

  • 📅 Monthly OPEX (Dec 19 - 25 days): ±$2.98 (±6.61%) → Range: $42.01 - $47.96
  • 📅 Quarterly Triple Witch (Dec 19 - 25 days): ±$2.98 (±6.61%) → Range: $42.01 - $47.96
  • 📅 Yearly LEAPS (Dec 18, 2026 - 389 days): ±$11.43 (±25.42%) → Range: $33.55 - $56.41

Translation for regular folks:

Options traders are pricing in a 6.6% move ($3) by December 19th expiration - that's only 25 days away! The market expects SLG to trade between $42-48 through year-end, which aligns perfectly with current technical support/resistance zones.

The longer-term LEAP implied move is MASSIVE: 25% ($11) over the next year, suggesting the stock could trade anywhere from $33.55 to $56.41 by December 2026. This wide range reflects high uncertainty about Manhattan office market recovery, refinancing outcomes, and REIT sector dynamics.

Key insight for the put calendar spread: The December 2026 implied move range tops out at $56.41 - still well below the $65 strike on this trade. The market is pricing in a scenario where SLG likely stays range-bound between $35-55 for the next year. The put seller is betting both legs stay in-the-money, profiting from time decay differential.

Q4 2024 Earnings Report - January 22, 2025 (Coming in ~2 months) 📊

SLG's Q4 2024 earnings release scheduled for January 22, 2025 after market close, with conference call January 23 at 2 PM ET, represents a critical inflection point:

  • 📊 Occupancy target: Management guidance calls for reaching 93.2% Manhattan same-store office occupancy by December 31, 2025 (up from 92.4% in Q3)
  • 💰 FFO expectations: 2025 full-year guidance of $5.65-$5.95 FFO per share (raised by $0.40 in Q3)
  • 🏢 Leasing momentum: Expect updates on achieving 1.9M+ SF of leasing activity in 2025
  • 📈 Same-store NOI: Critical metric after negative trends in Q2 (-1.0%) and Q3 (-4.2%) YoY

Why this matters: Management needs to deliver on occupancy targets and positive same-store NOI guidance to rebuild credibility after the stock's 33% decline. Any miss or conservative 2026 outlook could accelerate selling.

2026 Outlook Presentation - December 2025 📅

Company plans detailed 2026 outlook presentation at investor conference in December 2025:

  • 🎯 2026 FFO guidance: Consensus at $5.43, Jefferies at $5.34 - below 2025 levels
  • 📊 Same-store NOI recovery: Management expects positive growth in 2026 after 2025 weakness
  • 🏗️ Capital deployment: Updates on $730M Park Avenue Tower integration and $160M 346 Madison development
  • 💸 Refinancing strategy: Critical updates on addressing 2026 debt maturities

346 Madison Avenue Acquisition Closing - Expected Q4 2025 🏗️

Development site purchase for $160M expected to close by year-end:

  • 📍 Location: 346 Madison Avenue & 11 East 44th Street in East Midtown
  • 🏢 Development potential: ~800,000 rentable square feet under East Midtown rezoning
  • 📊 Proposed tower: 41-story, 643 feet tall with 19,000-22,000 SF floor plates
  • ⚠️ Risk factor: Ground-up development carries execution risk and capital deployment pressure

🚀 Near-Term Catalysts (Q1-Q2 2026)

Park Avenue Tower Acquisition Closing - Q1 2026 🏢

Major $730M acquisition of 65 East 55th Street from Blackstone expected to close Q1 2026:

  • 📏 Building specs: 36-story, 621,824 SF Class A office tower designed by Helmut Jahn
  • 💰 Revenue potential: ~$46.6M annually at stabilized occupancy based on $74.89/SF Manhattan average
  • 🎯 Strategic value: Expands Park Avenue portfolio, adds trophy asset in prime Midtown
  • ⚠️ Integration risk: Current occupancy undisclosed; stabilization may require capital investment
  • 💸 Balance sheet impact: $730M deployment at time of constrained capital markets access

5 Times Square Conversion Construction Start - By End 2025 🏗️

Partnership with Apollo Global & RXR to convert 1.1M SF office tower into 1,250 residential units:

  • 🏠 Unit mix: 1,250 rentals (313 permanently affordable for 467-m tax incentive)
  • ⏰ Timeline: Construction start by end-2025, Phase 1 completion expected 2027
  • 💵 Economics: Removes 1.1M SF from office inventory but creates residential revenue stream starting 2027
  • 🎯 Strategic pivot: Demonstrates ability to reposition underperforming office assets
  • ⚠️ Execution risk: $805M+ total project cost with deferred returns until lease-up

📊 Market Catalysts (2026)

Manhattan Office Market Recovery Trajectory 🏙️

Manhattan leasing volume hit 30.05M SF through Q3 2025 - strongest year-to-date period since 2002:

  • 📈 Q3 2025 leasing: 9.42M SF activity
  • 🎯 Large transactions: 40 deals exceeding 100K SF YTD (highest since 2018)
  • 📉 Availability improvement: Manhattan availability at 14.6%, down 0.8pp - first decrease in six straight quarters since 2014
  • 💰 Rising rents: Average asking rent of $74.89/SF (up 1.4% in Q3), highest since November 2023
  • ⚠️ Physical occupancy: Only 57.4% relative to February 2020 levels - structural WFH headwind remains

Federal Reserve Interest Rate Environment 💵

Lower interest rates reduce REIT borrowing costs and boost valuations:

  • 📉 Rate trajectory: Moderating rates alongside steady economic growth creates "soft landing" scenario
  • 💰 Cap rate compression: Easier refinancing and lower discount rates improve REIT NAV calculations
  • 🎯 Valuation catalyst: Monetary policy easing expected to close public-private cap rate gap
  • ⚠️ Current reality: Rates remain elevated vs 2020-2021 levels, limiting near-term benefit

⚠️ Risk Catalysts (Major Concerns!)

2026 Debt Maturity Wall - CRITICAL RISK 🚨

$1.5 TRILLION in commercial real estate loans mature by end-2026, with office REITs facing disproportionate refinancing pressure:

  • 💥 Peak maturities: $936B in 2026 debt maturities (19% more than 2025)
  • 🏢 Office sector vulnerability: Shorter-term loan maturities vs other REIT sectors create heightened refinancing risk
  • 💸 SLG exposure: Historical $2.0B in 2025 maturities (though recent $2.1B refinancings extended some)
  • ⚖️ Higher rates: Refinancing at elevated interest rates reduces cash flows and compresses margins
  • 📉 Property valuations: Falling office valuations complicate refinancing negotiations
  • 🎯 Probability: 60-70% likelihood of facing meaningful refinancing headwinds

Same-Store NOI Deterioration Trend 📉

Concerning negative same-store NOI trajectory through 2025:

  • Q1 2025: Cash NOI +2.6% YoY (excluding lease termination income: +2.4%)
  • Q2 2025: Cash NOI -1.0% YoY (excluding lease termination income)
  • Q3 2025: Cash NOI -4.2% YoY (excluding lease termination income: -5.5%)
  • Nine months 2025: Cash NOI -0.8% YoY (excluding lease termination income: -1.6%)

Translation: Revenue per square foot is declining as leasing spreads turn negative and tenant demand softens. This is the opposite of what a REIT needs to justify current dividend and valuation.

Geographic Concentration Risk 🗽

100% exposure to NYC market creates vulnerability:

🎲 Price Targets & Probabilities

Using gamma levels, implied move data, catalysts, and the put calendar spread structure, here are scenarios through 2026:

📉 Bear Case (40% probability)

Target: $35-42 by May 2026, staying below $50 through December 2026

How we get there:
- 😰 Q4 earnings disappoint with occupancy miss (below 93.2% target) and conservative 2026 guidance
- 🚨 Same-store NOI continues declining in Q1/Q2 2026, dropping 5-7% YoY
- 💸 Refinancing headwinds materialize - unable to extend debt on favorable terms
- 🏢 Manhattan office recovery stalls as physical occupancy stays below 60%
- 📉 Leasing spreads remain negative, forced to offer concessions to retain tenants
- 💰 Dividend cut risk emerges if FFO falls below $5.00/share
- 🔨 Break below $42.25 support triggers cascade toward $35-38 range
- 📊 Geographic concentration disadvantage vs diversified peers becomes apparent

Key metrics signaling Bear Case:
- 2026 FFO guidance below $5.00/share (current consensus: $5.43)
- Same-store NOI down 5%+ YoY in Q1 2026
- Occupancy declining from Q3 levels
- Failed refinancings or material rate increases

Put Calendar Spread P&L:
- May 2026: Short puts expire with intrinsic value ~$20 ($65 strike - $45 stock), trader pays out $11.2M but collected $12M initially = net $800K profit on short leg
- December 2026: Long puts worth ~$30 ($65 strike - $35 stock), value = $16.8M vs $13M cost = $3.8M gain
- Total P&L: +$4.6M profit (450% ROI on $1M net debit)

Probability assessment: 40% because it requires multiple negative catalysts - refinancing difficulties, continued NOI declines, dividend pressure. However, the 33% decline in past 3 months shows market already pricing in significant risk. The put buyer clearly sees this as BASE CASE, not tail risk.

🎯 Base Case (45% probability)

Target: $40-50 range (CHOPPY CONSOLIDATION)

Most likely scenario:
- ✅ Q4 earnings meet lowered expectations, achieve ~92.5-93% occupancy
- ⚖️ 2026 FFO guidance of $5.25-5.50 (slight decline from 2025)
- 🏢 Same-store NOI stabilizes around flat to slightly negative
- 🏗️ Park Avenue Tower and 346 Madison acquisitions close successfully
- 💸 Refinancings completed but at higher rates, compressing margins
- 📊 Stock trades in $42-50 range, unable to sustain breaks either direction
- 🎢 Gamma walls at $48 and $50 contain price action
- 💤 Implied volatility stays elevated (25-30%) but doesn't spike
- ⏰ Conversion projects (750 Third Ave, 5 Times Square) progress but don't generate returns yet

Put Calendar Spread P&L:
- May 2026: Stock at $45, short puts expire with intrinsic value $20, net flat on short leg after initial premium
- December 2026: Stock at $45, long puts worth $20, roughly breakeven after time decay
- Total P&L: -$500K to +$500K (small loss to small gain, roughly flat)

Why 45% probability: This is the "muddle through" scenario where SLG survives but doesn't thrive. Refinancings work out, occupancy doesn't collapse, but no catalyst for upside. Stock stays range-bound while management executes conversions and integrates acquisitions. Given the structural headwinds facing office REITs, this seems most likely.

The put calendar spread structure suggests the trader expects this - happy to collect time decay on short leg while maintaining long-term bearish positioning.

📈 Bull Case (15% probability)

Target: $55-65 (RECOVERY RALLY)

How we surprise to upside:
- 💪 Q4 earnings BEAT with occupancy exceeding 93.5%, positive same-store NOI inflection
- 🚀 2026 guidance surprises at $5.75+ FFO with strong leasing pipeline
- 💰 Fed rate cuts accelerate, REIT valuations expand materially
- 🏙️ Manhattan office recovery exceeds expectations - physical occupancy hits 65%+
- 📈 Leasing spreads turn meaningfully positive (+5-10% cash spreads)
- 🏢 Park Avenue Tower integration smooth, immediately accretive
- 💵 Institutional buyers return to office REITs, sector rotation
- 🎯 Conversion projects de-risked with successful financing and pre-leasing

Critical requirements:
- Same-store NOI positive growth resuming by Q1 2026
- Dividend safety confirmed with FCF coverage
- Refinancing completed with minimal rate increases
- Manhattan market fundamentals inflecting positively

Put Calendar Spread P&L:
- May 2026: Stock at $55, short puts expire worthless, trader keeps full $12M premium
- December 2026: Stock at $60, long puts worth ~$5 (minimal intrinsic value), worth maybe $3M
- Total P&L: -$10M loss (trader loses money as bearish thesis fails)

Probability assessment: Only 15% because it requires PERFECT execution plus external tailwinds (Fed cuts, market recovery). The stock's failure to hold $75-80 levels during favorable H1 2025 shows limited conviction. Current structural office headwinds (WFH, refinancing wall, geographic concentration) create significant upside barriers.

For the put calendar trader, this is the LOSS scenario. If SLG recovers to $55-65, they pay out on the short puts and the long puts lose value. But they're clearly willing to accept 15% odds of being wrong to capture 85% odds of profit from continued weakness.

💡 Trading Ideas

🛡️ Conservative: Avoid Until Clarity Emerges

Play: Stay on sidelines until Q4 earnings and 2026 guidance provide direction

Why this works:
- ⏰ Q4 earnings on January 22 (2 months away) creates binary event risk with multiple unknowns
- 💸 Stock down 33% in 3 months but still faces $1.5T CRE maturity wall in 2026
- 📊 Same-store NOI declining for two straight quarters - negative momentum
- 🎯 Implied volatility at 25%+ means options expensive relative to slow-moving REIT
- 🚨 $25M institutional calendar spread signals smart money expects continued weakness
- 📉 Better entry likely post-earnings if stock breaks below $42 support to $35-38 range
- 💰 7% dividend yield attractive but at risk if FFO deteriorates

Action plan:
- 👀 Watch Q4 earnings January 22 for occupancy achievement (93.2% target), same-store NOI trends, and 2026 FFO guidance
- 🎯 Look for breakdown below $42 support (52-week low) for entry at $38-40 with 15-20% discount
- ✅ Need to see refinancing strategy clarity and positive same-store NOI guidance for 2026
- 📊 Monitor Manhattan office metrics monthly - physical occupancy, leasing volume, rent trends
- ⏰ Revisit in Q1 2026 after 346 Madison and Park Avenue Tower integrations begin

Risk level: Minimal (cash position) | Skill level: Beginner-friendly

Expected outcome: Avoid catching falling knife. Wait for genuine inflection in fundamentals (positive NOI growth, refinancing clarity, dividend safety confirmed). Miss potential bounce from $45 to $50, but avoid further 20-30% decline if bear case materializes.

⚖️ Balanced: Sell Cash-Secured Puts at Support

Play: Sell cash-secured puts at technical support to generate income with defined entry price

Structure: Sell March 2026 $40 puts for ~$2.00-2.50 premium

Why this works:
- 💰 Collect 5-6% income over 4 months while waiting for potential entry
- 🛡️ $40 strike near 52-week low of $42.92 provides technical support cushion
- 📊 If assigned, net entry at $37.50-38 (strike minus premium) = 16% discount from current $45
- 💵 At $38 entry with 7% dividend yield = attractive total return potential if SLG stabilizes
- ⏰ March expiration captures Q4 earnings reaction and 2026 guidance
- 🎯 Worst case: own quality Manhattan REIT at significant discount with high yield

Estimated P&L:
- 💰 Collect $200-250 per contract ($250 × 40 = $10,000 income on $40,000 capital)
- 📈 Best case: SLG stays above $40, keep premium, repeat strategy = 5% quarterly income
- ⚖️ Neutral case: Assigned at $40, net cost $37.50-38, hold for 7% dividend = good long-term entry
- 📉 Worst case: SLG drops to $35, unrealized loss offset by dividend income over time

Entry timing:
- ⏰ Wait for post-earnings clarity (late January) before selling puts
- 🎯 Only execute if SLG above $43 (gives buffer to $40 strike)
- ❌ Skip if SLG already below $41 (too close to strike)

Position sizing:
- Risk 5-10% of portfolio (this is income strategy with stock ownership risk)
- Must be comfortable owning SLG at net $37.50-38 entry if assigned
- Keep cash available to handle assignment

Risk level: Moderate (obligation to buy stock, but at discount) | Skill level: Intermediate

🚀 Aggressive: Copy The Calendar Spread Structure (Scaled Down!)

Play: Replicate institutional put calendar spread at smaller scale

Structure:
- Buy 10 contracts Dec 2026 $60 puts @ ~$19.00 = $19,000
- Sell 10 contracts May 2026 $60 puts @ ~$17.00 = $17,000
- Net debit: ~$2.00 per spread = $2,000 total risk

Why this could work:
- 🎯 $60 strike still well above current $45 price (33% buffer) but more realistic than $65
- 💸 Much more capital-efficient than buying puts outright ($2K vs $19K)
- 📊 Profits if SLG stays weak through 2026 (bear/base case = 85% combined probability)
- ⏰ May short leg captures Q4 earnings and Q1 2026 results before expiring
- 🤝 Following smart money positioning - institutional player just deployed $25M in this structure
- 💰 Max profit if SLG between $40-50 at May expiration (short puts expire worthless, long puts retain value)

Why this could blow up (SERIOUS RISKS!):
- ⚠️ Max loss = $2,000 per spread if SLG rallies above $60 by Dec 2026 (15% probability but possible)
- 📉 Early assignment risk: Short May puts can be assigned if SLG drops below $60 (forces stock purchase at $60 when it might be $45)
- 💸 Margin requirement: Broker may require $60,000 buying power per 10-contract spread due to short put exposure
- 🎢 Complexity risk: Calendar spreads have nuanced risk/reward that changes with stock movement and time
- ⏰ Time decay cuts both ways: If SLG stays at $45, both legs decay - not guaranteed profit

Estimated P&L scenarios:

Bear Case ($35-40 at May expiration):
- May short puts assigned: Pay $60, stock worth $38 = $22,000 loss
- December long puts worth $22 = $22,000 value
- Net: Roughly breakeven to small profit after initial $2K debit

Base Case ($45 at May expiration):
- May short puts: Intrinsic value $15, roll or pay $15,000
- December long puts: Worth $15-18 from intrinsic + time value
- Net: Small profit $3,000-5,000 (150-250% ROI on $2K investment)

Bull Case ($55+ at May expiration):
- May short puts: Expire worthless, keep $17,000 premium
- December long puts: Worth $5-10 at most
- Net: Significant profit $15,000+ (750%+ ROI!)

CRITICAL WARNINGS - DO NOT attempt unless you:
- ✅ Understand early assignment risk on short puts and have capital/margin to handle it
- ✅ Can monitor position weekly and manage the short leg at May expiration
- ✅ Comfortable with defined $2,000 risk but also early assignment scenarios
- ✅ Have traded calendar spreads before and understand time decay dynamics
- ✅ Recognize this is a DIRECTIONAL bearish bet, not a neutral income strategy
- ⏰ Plan to actively manage - may need to roll short leg at expiration if still ITM
- 💰 Have margin/cash available for potential assignment ($60,000 per 10 contracts)

Position sizing:
- Max 5% of portfolio in this trade (it's sophisticated speculation)
- Start with 5-10 contract spread ($1,000-2,000 risk) to learn the structure
- Scale up only after understanding how calendar spreads behave

Risk level: HIGH (complex structure, margin requirement, directional risk) | Skill level: Advanced only

Probability of profit: ~55-60% (profits in bear/base case, loses in bull case)

⚠️ Risk Factors

Don't get caught by these potential landmines:

🎯 The Bottom Line

Real talk: Someone just spent $25 MILLION on a sophisticated put calendar spread betting SLG stays under pressure through 2026. This isn't a short-term trade - this is a YEAR-LONG bearish position using calendar spread mechanics to finance extended downside exposure at 96% cost reduction ($1M net vs $13M outright puts).

What this trade tells us:
- 🎯 Institutional player expects SLG to remain below $65 for the next 12+ months (85%+ conviction level)
- 💸 They're worried about 2026 refinancing wall, same-store NOI deterioration, and structural office headwinds
- ⚖️ The calendar structure (sell May, buy December) suggests belief in continued weakness through BOTH expirations
- 📊 Striking at $65 when stock is $45 (44% above current) shows expectation of NO meaningful recovery
- ⏰ They're willing to manage early assignment risk on 5,600 short puts in May rather than just buying outright protection

This is NOT a "panic sell" signal - it's a "don't expect recovery anytime soon" signal.

If you own SLG:
- ✅ Seriously evaluate your thesis given 33% decline, negative same-store NOI trends, and 2026 refinancing risks
- 📊 If holding for 7% dividend, confirm you're comfortable with dividend cut risk if FFO drops below $5.00
- ⏰ Set mental stop at $42 (52-week low) to protect against further cascade to $35-38
- 🎯 Consider trimming 25-50% here at $45 and waiting for Q4 earnings clarity on January 22
- 🛡️ If keeping position, consider selling covered calls at $50 strike to generate income in range-bound environment

If you're watching from sidelines:
- ⏰ DO NOT chase this down - wait for Q4 earnings January 22 and 2026 guidance in December
- 🎯 Better entry likely at $38-42 if bear case materializes (breakdown below 52-week low)
- 📈 Looking for inflection signals: positive same-store NOI returning, successful refinancings, occupancy exceeding 93.5%
- 🚀 Long-term value play IF you believe Manhattan office recovers and SLG navigates 2026 refinancings
- ⚠️ But recognize this is a SHOW ME story - need proof of execution before committing capital

Final verdict: SLG faces a defining year in 2026. The $25M put calendar spread reflects institutional conviction that office REIT headwinds (refinancing wall, structural WFH, same-store NOI pressure, geographic concentration) outweigh positives (trophy assets, conversion strategy, leasing momentum). At $45 after a 33% decline with 7% yield, value investors might be tempted - but the smart money is saying "not yet."

The trade structure tells you everything: they're not betting on a crash to $30, they're betting on prolonged weakness in the $40-50 range through 2026. That's actually MORE concerning than outright panic - it suggests fundamental challenges that take time to resolve.

Be patient. Let Q4 earnings clear. Watch for same-store NOI inflection and refinancing clarity. The 7% dividend will still be there in 3 months - if it's sustainable. But if it gets cut, that $45 stock becomes $35 overnight.

REITs don't go to zero, but they can disappoint for years. Protect your capital. 💪
