🤓 What This Actually Means

These are two bullish bets with different time horizons:

Trade #1: Near-Term Momentum Play

  • 3,000 contracts of $160 calls expiring October 17th
  • Already $9.54 in-the-money (spot at $169.54)
  • Premium of $3.7M suggests institutional positioning for continued strength
  • Just 4 days until expiration - expecting near-term catalyst or momentum

Trade #2: Earnings Conviction Play

  • 750 contracts of $150 calls expiring November 21st
  • Deep $22.92 in-the-money
  • Expires 16 days AFTER November 5th earnings
  • This is a pure earnings play betting on blowout results

Unusual Score: 🔥 EXTREME (1,412x average size) - This happens maybe once a year for ARM options!

📈 Technical Setup / Chart Check-Up

YTD Performance Chart

ARM YTD Performance

ARM is absolutely crushing it this year with +33.3% YTD performance! The chart tells a story of institutional accumulation and AI-driven momentum:

Key observations:

  • Recovery from February dip: Bounced strongly from $110 lows back in March
  • Breakout territory: Currently trading at $170.84, pushing toward new highs
  • High volatility environment: 66.7% IV signals big moves expected
  • Volume spikes: Recent institutional buying pressure visible in August volume surge
  • Strong uptrend: Clear higher lows pattern since March bottom

The stock has recovered from a brutal 52.3% max drawdown and is now showing renewed strength heading into earnings season.

🎯 Gamma-Based Support & Resistance Analysis

ARM Gamma S/R

Current Price: $171.55

The gamma chart reveals critical levels that explain why institutional money is piling in:

Resistance Levels (Orange Bars - Call Gamma Above Price):

  • $175: Nearest resistance just 2.1% away - strongest level with 2.8M total GEX
  • $180: Major wall at 4.9% above - massive 8.5M GEX concentration (strongest resistance)
  • $190: Secondary resistance at 10.8% up
  • $200: Psychological level at 16.6% away with 5.1M GEX

Support Levels (Blue Bars - Put Gamma Below Price):

  • $170: Immediate support just 0.8% below - strongest support with 5.8M total GEX
  • $165: Secondary floor at 3.8% down
  • $160: Strong support at 6.7% below with 5.5M GEX
  • $150-145: Deep support zone at 12-15% down

Net GEX Bias: BULLISH 📈

  • Total Call GEX: 53.0M vs Put GEX: 21.8M
  • This 2.4:1 ratio means market makers will need to buy stock as price rises, creating upward momentum
  • The $180 level is the key battleground - breaking above unleashes serious gamma squeeze potential

What This Means: The call buyer at $160 is betting ARM breaks through the $175 resistance and heads toward $180. With gamma stacked above, any breakout creates self-fulfilling upward pressure. The $170 support floor provides a safety net just below current price.


🎪 Catalysts

🔮 Upcoming Events

Q2 FY26 Earnings - November 5, 2025 The biggest catalyst on the horizon! According to MarketChameleon's earnings watch, this report will be critical for:

  • Data center growth metrics (targeting 50% market share by year-end)
  • v9 architecture adoption rates (commanding double the royalty rates)
  • AI infrastructure revenue expansion
  • Forward guidance for fiscal 2026

Data Center Market Expansion ARM expects its share of the global data center CPU market to surge from 15% in 2024 to 50% by end of 2025. This dramatic expansion is driven by:

ARM v9 Architecture Rollout The transition to v9 architecture represents a major financial catalyst with approximately double the royalty rates of previous generation:

✅ Recently Completed

Record Q1 FY26 Results ARM broke through the $1 billion quarterly revenue milestone for the first time, with Q1 2026 revenue of $1.053 billion. Full fiscal 2024 achieved record revenue of $4.01B, representing 25.3% year-over-year growth.

Automotive Semiconductor Growth The automotive ARM-based microcontroller market is projected to reach $5.43B in 2025, expanding at 5.4% CAGR through 2033, driven by:


🎲 Price Targets & Probabilities

Using gamma levels, catalyst timing, and technical setup:

🚀 Bull Case (35% chance)

Target: $180-$190

If ARM breaks through the $175 resistance, the path to $180 opens up quickly. The gamma squeeze effect above current levels creates natural momentum. This case plays out if:

  • Earnings preview commentary suggests strong Q2 results
  • Data center customer announcements ahead of November 5th
  • Broader semiconductor sector strength
  • AI infrastructure boom continues driving adoption

The $3.7M near-term call buyer profits big in this scenario - $160 strikes would be $20-30 ITM.

😐 Base Case (45% chance)

Target: $165-$180 range

ARM consolidates in current range, testing $175 resistance but staying below the major $180 gamma wall. This scenario reflects:

  • Choppy pre-earnings trading as investors wait for November 5th
  • Profit-taking after recent rally to $172
  • Strong $170 support holds on any dips
  • Market digests recent 33% YTD gains

Both call positions remain profitable but don't see explosive gains before near-term expiration.

😰 Bear Case (20% chance)

Target: $160-$170

A pullback to test major support levels if broader market weakness or sector rotation occurs. This would require:

Near-term $160 calls still ITM but see theta decay. Longer-dated $150 calls remain protected.


💡 Trading Ideas

🛡️ Conservative: Ride the Support

Play: Bull put spread below gamma support

Sell $165 puts, buy $160 puts (Nov 21 expiration)

Risk: $5 per spread max loss Reward: $1.50-2.00 credit per spread Probability: ~70% success (below strong $165 support)

Why this works: Strong gamma support at $165 (3.1M GEX) and $160 (5.5M GEX) provides downside protection. Even in bear case, these levels likely hold.

⚖️ Balanced: Follow Smart Money

Play: Long calls with earnings exposure

Buy $175 calls (Nov 21 expiration)

Risk: Premium paid (~$10-12 per contract) Reward: Unlimited if earnings catalyst Probability: ~45% profitable

Why this works: Targets the $175 resistance breakout level with exposure through November 5th earnings. Mirrors the institutional strategy but at a more accessible strike.

🚀 Aggressive: Gamma Squeeze Play

Play: ATM call ratio spread

Buy 2x $172.50 calls, sell 1x $180 calls (Oct 17 expiration)

Risk: Limited above $180, premium at risk below $172.50 Reward: Maximum profit near $180 Probability: ~30% max profit

Why this works: If ARM breaks $175 resistance this week, gamma dynamics accelerate price toward $180. Ratio spread captures that specific move with defined risk.


⚠️ Risk Factors

High Valuation Sensitivity With a forward P/E of 84.16, ARM trades at premium valuations reflecting aggressive growth expectations. Any earnings disappointment could trigger sharp correction.

China Market Exposure ARM faces headwinds from China's push toward open-source RISC-V architecture. As ARM's second-largest market, government support for alternatives could accelerate competitive pressure.

Customer Relationship Tensions Reports of ARM hiring talent from major customers and considering chip development creates potential conflict with licensees that generate current revenue.

Earnings Binary Event November 5th earnings represent a major binary catalyst just days after the near-term calls expire. IV crush post-earnings could impact longer-dated positions.

Semiconductor Sector Correlation ARM moves with broader semiconductor trends. Any sector rotation or chip stock weakness affects ARM regardless of company-specific fundamentals.


🎯 The Bottom Line

Real talk: These $6M in bullish ARM call trades tell us institutional money expects continued strength heading into November earnings. The split between near-term and post-earnings positions shows sophisticated players layering risk.

If you own ARM: The $170 gamma support level is your line in the sand. Hold above that and momentum continues toward $175-180 resistance.

If you're watching: This week's price action determines the setup - break $175 and chase begins, fail at resistance and wait for $165-170 pullback entry.

If you're bullish: Consider spreads that target the $175-180 gamma zone while limiting downside exposure. The risk/reward favors defined-risk strategies given 84x P/E valuation.

Mark your calendar:

  • October 17: Near-term $3.7M call position expires - watch for delta hedging flows
  • November 5: Q2 FY26 earnings - THE catalyst for direction into year-end
  • Q4 2025: Expected acceleration in data center chip adoption as ARM targets 50% market share

The data center transformation story is real, v9 royalties are climbing, and AI infrastructure demand supports the bull case. But at these valuations, execution must be flawless. These option trades suggest big money thinks ARM delivers!
