🔄 CDNS $56.5M Position RESET One Day After Q1 Beat — Closing Sep Shorts, Opening Jun Bull Spread + Protective Put

📅 April 28, 2026 | 🔄 Position Reset / Roll Detected

---

🎯 The Quick Take

The morning after Cadence Design Systems crushed Q1 FY2026 estimates — $1.474B revenue (+18.7% YoY), a record $8B backlog, and a raised full-year revenue guide — a sophisticated institutional trader executed a coordinated six-leg position reset totaling $56.5M in gross premium across two distinct timestamp clusters. This is not a fresh bullish stack. It is a structured roll-and-replace: the 09:32 block closed three existing September/January positions (paying ~$20.6M to buy back short calls, receiving $1.6M to close a long put), and the 10:04 block deployed a entirely new three-leg June/August structure with a $1.7M net debit. Translation: the trader took off stale September short-call exposure that had likely been pressured heading into earnings, then immediately replaced it with a tighter, defined-risk June bull spread capped at $380 through August.

📊 Company Overview

Cadence Design Systems (CDNS) is the backbone software that powers the design of virtually every advanced semiconductor on the planet:

• Market Cap: ~$88–93B (per Capital.com market data)
• Industry: Electronic Design Automation (EDA) — the software that chip designers use to lay out, simulate, verify, and tape out semiconductors before manufacturing
• Current Price: ~$323 (April 28, 2026, day after Q1 earnings)
• Primary Business: EDA tools, hardware emulation/prototyping platforms (Palladium Z3, Protium X3), IP licensing, and — increasingly — agentic AI design automation (ChipStack, AgentStack, ViraStack, InnoStack)
• Why it matters now: When NVIDIA, Apple, AMD, Google, and every hyperscaler races to design the next custom AI chip, every one of them pays Cadence. The AI silicon boom is a structural tailwind for CDNS that does not require picking winners in the chip race — Cadence gets paid regardless

🔄 What This Actually Means — A Two-Act Position Reset

This is not six simultaneous legs of one new directional bet. It is a two-act drama separated by 32 minutes, and you cannot read the trade correctly unless you honor that distinction. Three legs are CLOSING existing positions. Three legs are OPENING a new structure. Here is exactly what happened:

---

Act 1 — 09:32:14: The Wind-Down (3 CLOSING trades)

The 09:32 block consists entirely of closing orders: two Buy-to-Close (BTC) on short calls, and one Sell-to-Close (STC) on a long put. This trader was previously short the Sep $310 and Sep $320 calls and long the Jan 2027 $270 put. The morning after a Q1 earnings print that sent CDNS from ~$221 lows to the $323–$329 area, those short calls had gone deeply in-the-money. With CDNS near $329, the $310 and $320 short calls are ITM by $19 and $9 respectively — painful marks.

• BTC $310 Sep Call — $8.6M debit (1,600 contracts): Paying $54/contract to buy back a short call that is now deep ITM. Z-score of 5.65 confirms meaningful prior open interest. The trader is paying a substantial cost to close a position that moved against them.
• BTC $320 Sep Call — $12M debit (2,500 contracts): The larger of the two buybacks. At $49/contract with CDNS near $329, this is also now ITM. Z-score of 3.81, existing OI of 1,500 before this trade. Again — this is a painful but necessary close.
• STC $270 Jan 2027 Put — $1.6M credit (800 contracts): Selling back a long put that was presumably purchased as downside protection for the original short-call structure. With CDNS rallying hard post-earnings, this put has lost most of its value. Receiving $20/contract ($1.6M) closes out the protective leg.

Net Act 1 cash flow: the trader PAID approximately $19M to exit these three positions. This is not a profit booking — this is the cost of closing short-call exposure that moved against the original trade after CDNS's recovery from April lows into and through earnings.

---

Act 2 — 10:04:06: The Rebuild (3 OPENING trades)

Thirty-two minutes later, with CDNS trading slightly lower at $327.65, fresh capital is deployed into a completely new three-leg structure. These are all opening orders:

• BTO $350 Jun Call — $14M debit (10,000 contracts at $14.33): The directional engine of the new position. Targets a ~7% rally in CDNS to $350+ by June 18. The Z-score of 77.45 on this leg is extraordinary — volume of 10,000 against just 1,500 prior OI (a 6.7x vol/OI ratio). This is fresh institutional capital committing to a June upside view. The Jun expiration is 51 days away from the trade date.
• BTO $300 Jun Put — $2.3M debit (2,000 contracts at $11.51): Downside insurance at $300, approximately 8.5% below spot. This is a protective wing: if CDNS breaks down on a macro shock, China export-control reversal, or Hexagon integration scare, the put begins generating intrinsic value below $300 and offsets losses on the long call position and any underlying stock.
• STO $380 Aug Call — $18M credit (10,000 contracts at $17.71): The ceiling and the funding mechanism. By selling the Aug $380 call with only 24 contracts of prior OI, this trader generated an $18M inflow on a completely fresh, nearly uncovered strike. The Z-score of 3,456 is the single most unusual data point in today's entire CDNS flow — this level simply did not exist as a meaningful position before this print. Selling the $380 strike (17% above spot) caps upside at $380 through August while generating enough credit to almost entirely offset the cost of the $350 call and $300 put.

Net Act 2 cash flow: $14M + $2.3M debit minus $18M credit = approximately $1.7M net debit to enter the entire new three-leg structure.

---

The Full Picture — Why This Is a Roll, Not a New Bet

The key narrative: This is a trader who was short Sep calls and got squeezed as CDNS rallied from the April lows back through $329. Rather than carry that pain through another quarter, they paid $19M to close the short-call exposure post-Q1 earnings and immediately repositioned into a cleaner, defined-risk June bull spread funded by the August short call. The thesis — bullish on CDNS — did not change. The structure did.

📈 Technical Setup / Chart Check-Up

YTD Performance Chart

CDNS has had a dramatic year. Per the catalyst research and Yahoo Finance, the stock hit a 52-week high of $376.44 in July 2025 before pulling back to a 52-week low of $221.56 in early April 2026 — a brutal drawdown in line with broader tech and semiconductor volatility. From that April low, the stock has recovered to the $320–$330 zone heading into earnings, roughly +46% off the bottom.

Key observations:

• Sharp V-shape recovery: From $221 in early April to $329 pre-earnings is an aggressive rebound — short squeeze + fundamental buyers absorbing the macro-driven selloff. This is also what caused the 09:32 short-call pain: those Sep short calls were presumably opened when CDNS was lower, and the recovery crushed them.
• Still well below the $376 52-week high: CDNS has ~15–16% of recovery work left to reach prior highs, which is exactly the target range the new long Jun call is aiming toward
• Earnings cleared as an overhang: The Q1 beat-and-raise on revenue removes the biggest near-term binary event; the focus now shifts to Q2 execution and Hexagon integration
• Gamma-relevant price zone: Current trading between $320 immediate support and $330 first resistance — a tight range that will depend on whether the market buys the revenue raise narrative or sells the EPS cut narrative

Gamma-Based Support & Resistance Analysis

Current Price: $323.48

The gamma exposure map shows market maker positioning that creates mechanical support and resistance floors through options expiration:

Support Levels (Put Gamma Below Price):

• $320 — Immediate support, total gamma exposure 1.05B. This is the first floor the stock needs to hold; it also aligns with the Sep $320 short call that was just bought back this morning — the prior holder was anchored at this level
• $310 — Secondary support at 1.47B total gamma; this is exactly where the Sep $310 short call was closed — the prior holder clearly saw this as a structural anchor
• $300 — Major structural floor at 3.67B total gamma (highest put-gamma concentration on the board at net -1.83B). This is THE line in the sand: if CDNS cracks $300, dealer hedging flips heavily, momentum accelerates south — and the newly opened $300 protective put kicks in precisely at this level. The alignment is intentional.
• $290 — Extended floor at 2.26B gamma (net -0.66B)
• $280 — Deeper support at 0.53B gamma — thin coverage, suggesting $280 would be a fast move if $290 breaks

Resistance Levels (Call Gamma Above Price):

• $330 — Immediate ceiling at 1.83B total gamma (~2% above spot). This is the nearest resistance and the near-term lid; clearing it confidently opens the path higher
• $335 — Secondary resistance at 0.99B gamma (3.6% above spot)
• $340 — Medium resistance at 0.50B gamma (5.1% above spot)
• $350 — Key resistance level at 1.06B gamma — this is precisely where the new BTO long call is struck. Once the market gets above $350, call gamma dealers start selling less aggressively and the level can convert from friction to fuel
• $380 — Upper wall at 1.15B gamma — aligns perfectly with the new STO short call strike, suggesting the trader used the gamma map to inform exactly where to sell the cap

Net GEX Bias: Bullish (11.2B call gamma vs. 10.0B put gamma) — overall positioning is tilted bullish, with meaningful put-gamma concentration at $300 serving as the critical structural floor and defining the BTO $300 put's rationale.

What this means for traders: CDNS is sandwiched between $320 immediate support and $330 first resistance. A clean break above $330 likely catalyzes a run toward $340–$350 — exactly the range the new long BTO call is designed to capture. The $300 put-gamma floor is the last defense before market structure deteriorates.

Implied Move Analysis

Options market pricing for upcoming expirations:

• Weekly (May 1 — 3 days): ±$11.81 (±3.68%) → Range: $309.50–$333.13. Captures the immediate post-earnings settling period — the market is pricing about a 3.7% swing in either direction by Friday
• Monthly OPEX (May 15 — 17 days): ±$23.29 (±7.25%) → Range: $298.03–$344.61. Getting close to the gamma-heavy $300 support floor on the downside and approaching the $344 mid-range on the upside
• June Triple Witch (Jun 19 — ~52 days): Upper $354.13 / Lower $288.51 — this is the expiration most relevant to the new Jun $350 BTO call. The implied move upper range of $354 sits just above the $350 strike, meaning the market is pricing a meaningful but not overwhelming probability of reaching the new long call's strike
• August OPEX (Aug 21 — matches the STO $380 call): Upper $367.41 / Lower $275.23. The sold $380 call sits comfortably ABOVE the implied move upper range of $367 — the trader structured the short call cap above where the market's own probability model sees CDNS reaching by August. That is disciplined risk management.
• LEAP range (Mar 2027): ±$91.46 (±28.46%) → Range: $229.86–$412.78

Key insight on the new Jun $350 BTO call: The June upper implied move boundary is $354 — just barely above the $350 strike. That means the market is currently pricing this call with relatively low probability of going deep ITM. The institutional BTO buyer is making a bet that CDNS will outperform the options market's current implied probability — which is why conviction behind the fundamental catalyst stack (Q2 print, NVIDIA tape-outs, TSMC N2 ramp) matters so much to this trade's success.

Already Happened — Cleared Events

Q1 FY2026 Earnings (April 27, 2026 — reported yesterday):

Cadence crushed Q1 expectations with revenue of $1.474B (+18.7% YoY), non-GAAP EPS of $1.96 (vs. $1.89 consensus per StockTitan), and a record $8.0B backlog with ~$4.0B converting within 12 months. Full-year revenue guidance was raised to $6.125–$6.225B, but non-GAAP EPS was cut to $7.85–$7.95 from $8.05–$8.15 due to ~$0.28 Hexagon dilution. Stock was -1.48% after hours — a very mild reaction, suggesting the market absorbed the moving parts quickly. The Benzinga post-earnings recap confirmed accelerating AI demand as the dominant narrative.

Hexagon D&E Acquisition Closed (Q1 2026):

The €2.7B (~$2.95B) deal, structured 70% cash / 30% CDNS stock, is complete. Per the Q1 earnings transcript on The Motley Fool, management explicitly guided to EPS accretion in 2027 — the EPS guide cut is acquisition arithmetic, not operational deterioration. The deal added ~$160M full-year 2026 revenue. The associated EPS dilution of ~$0.28 is the headline negative but temporary.

NVIDIA Partnership Expansion (April 2026):

At CadenceLIVE Silicon Valley 2026, Cadence and NVIDIA announced an expanded partnership covering agentic AI chip design (claimed 100x solver speed-ups), AI factory digital twins via NVIDIA Omniverse DSX Blueprint, and physical AI systems for robotics. NVIDIA has publicly confirmed using Palladium Z3 and Protium X3 for Blackwell tape-out work, cementing the relationship at the highest product tier.

TSMC Collaboration Extended (April 2026):

Per HPCwire AIwire, Cadence expanded its TSMC IP and design infrastructure relationship across N3, N2, A16, and A14 process nodes — positioning Cadence directly into every leading-edge AI silicon tape-out for the next 3–5 years.

ChipStack / AgentStack / ViraStack / InnoStack Launch:

The ChipStack AI Super Agent suite is now in production with 10+ customers reporting up to 10x productivity gains per GuruFocus Q1 highlights. This is the product suite driving management's first-ever "Rule of 60" metric disclosure.

---

Upcoming Catalysts (Next 6 Months)

Q2 FY2026 Earnings — Late July 2026:

This is the next major binary event and the most important upcoming catalyst for the NEW position's thesis. The new Jun $350 BTO call expires on June 18 — BEFORE the Q2 print. The $380 STO short call expires August 21 — AFTER the Q2 print. This means: if CDNS rallies to $350+ by June 18, the BTO call captures the gain before Q2. If Q2 guidance is strong in late July, it supports the continued existence of the STO short call as a well-placed cap. Consensus implies ~$1.50–$1.55B revenue and ~$1.92–$2.00 non-GAAP EPS. Key watches: hardware book-to-bill, China revenue trend (held at 13% in Q1), Hexagon D&E quarterly ramp, and any update to the $8B backlog.

TSMC N2 Tape-out Wave (2H 2026):

Industry timing has N2 entering mass production ramp at TSMC in H2 2026. Cadence's expanded TSMC IP collaboration directly captures royalty and IP revenue from this cycle — and is precisely the kind of mid-cycle catalyst that could push CDNS through the $350 resistance level before the Jun expiration.

DAC 2026 (Design Automation Conference, June 2026):

This industry event sits squarely inside the Jun $350 BTO call window and historically drives momentum commentary around AgentStack/InnoStack adoption metrics. If Cadence shows compelling productivity data at DAC, it can catalyze institutional follow-through.

NVIDIA Vera Rubin / Rubin Ultra Tape-outs:

NVIDIA's Vera Rubin family designs are reportedly in active verification phase in 2026 per Cadence's emulation platform context. These are exactly the type of projects that drive Palladium Z3 hardware utilization and can accelerate backlog conversion ahead of the June window.

Hyperscaler Custom Silicon Pipeline:

Google TPUv7+, Microsoft Maia v2/v3, Amazon Trainium 3, and Meta MTIA v3 are all in flight per Cadence's hyperscale design positioning. Each new tape-out is a direct Cadence revenue event supporting the bull thesis.

Hexagon Synergy / 2027 Accretion Narrative:

As the integration proceeds through 2026, pace of synergy realization will determine whether the EPS-cut narrative gives way to an "accretion arriving in 2027" re-rating. Management's explicit 2027 accretion guidance from the earnings call is the bull case anchor for the intermediate horizon.

Risk Catalyst — China Export Control Decision (Ongoing):

Per the July 2025 EDA control rescission, EDA tools are currently permitted for sale to China. China represents 13% of Q1 revenue and the $140M DOJ/BIS settlement Cadence paid in 2025 shows how quickly policy can flip. Any re-imposition would carve 5–7% off the top line and represents the most asymmetric downside tail risk.

🎲 Price Targets & Probabilities — Based on the NEW Position

All price target analysis below reflects the new 10:04 three-leg structure only (BTO $350 Jun / BTO $300 Jun / STO $380 Aug). The closed 09:32 legs are gone — they have no further P&L impact.

Bull Case (35% probability)

Target: $350–$374 by June 18

How we get there:

• CDNS holds above $330 gamma resistance this week and breaks out convincingly
• Broader tech / semiconductor sentiment stabilizes or recovers as tariff-related volatility eases
• TSMC N2 tape-out timeline headlines, DAC 2026 AgentStack momentum, or any NVIDIA Vera Rubin confirmation creates a catalyst push before the Jun 18 expiration
• Institutional follow-through buying behind the new BTO structure
• The Jun implied move upper boundary sits at $354 — a clean breakout above $350 gamma resistance puts $354–$374 (the Sep triple-witch upper boundary) in range

New position P&L at various Jun 18 scenarios:

• At $340: Jun $350 call expires worthless (loss of $14M debit); Jun $300 put decays (loss of $2.3M); Aug $380 short call retains significant time value (paper loss if closed early, or manageable if held). Structure is underwater but the $380 credit still provides a long-dated cushion.
• At $355: Jun $350 call is $5 ITM — roughly $5M intrinsic × 10,000 contracts, offset against the $14M cost. $300 put expires worthless. The $18M STO credit from Aug is still outstanding. Overall position has recovered substantially from the debit cost.
• At $365: Jun $350 call has $15 intrinsic — $15M value vs. $14M cost, approximately breakeven to slight profit on the long call leg before factoring in the remaining Aug credit.
• At $375+: The Jun call generates meaningful gain; combined with the intact $18M Aug STO credit (still has time to expiry), the full position is solidly profitable.

Base Case (45% probability)

Target: $320–$350 — Gradual Grind, Jun Call Near-Worthless

Most likely scenario:

• CDNS holds $320 support, consolidates in $320–$340 range near-term as the market digests the EPS cut vs. revenue raise narrative
• Gamma pinning between $320 support and $330 resistance keeps price relatively anchored through May
• The Jun $350 BTO call expires at limited or zero value — this is the "cost of positioning" scenario
• The $18M STO credit from selling the Aug $380 call is fully retained through June expiration and continues to decay profitably through August
• The $300 BTO put provides residual floor value if CDNS dips toward support
• The position's net economics: ~$1.7M was the net debit to enter the new structure. Even in the base case where the $350 Jun call expires worthless, the $18M Aug credit remains on the books as a slowly decaying asset through August

Why this is survivable: The 10:04 structure was priced such that the STO short call credit ($18M) more than covered the total BTO debit ($16.3M), resulting in only a $1.7M net outlay. The Jun call expiring worthless costs the premium paid on it ($14M) but is offset significantly by the ongoing $18M credit collection — the trader structured this to be viable even in a sideways tape.

Bear Case (20% probability)

Target: $290–$300 — Test the Protective Floor

What could go wrong:

• Macro shock or renewed tariff escalation drives semis broadly lower
• China export control re-imposition announced, removing 13% revenue exposure overnight
• Hexagon integration hits a snag — cost overruns, talent attrition, or integration delays push accretion timeline past 2027
• Broader AI capex cooldown narrative takes hold after hyperscaler Q2 prints in late April/early May
• Break below $310 (gamma support) triggers acceleration toward $300 (the major 3.67B gamma wall)

At $300, the BTO $300 Jun put kicks in dollar-for-dollar. The $300 put (2,000 contracts at $11.51) starts generating real value below $300, limiting downside on the broader position. The sold $380 Aug call retains full credit value (far OTM). The Jun $350 call expires worthless. This is the "insurance pays off" scenario and demonstrates why the protective put was included as a third leg in the new structure.

Critical support levels:

• $320: Immediate gamma floor — must hold or the next test is $310
• $310: Secondary gamma anchor (1.47B total gamma) — also where the now-closed Sep short call was previously anchored
• $300: Major put-gamma wall (3.67B total gamma, net -1.83B) — THE line in the sand and precisely where the new BTO protective put lives

💡 Trading Ideas

Important context before any trade idea: The 09:32 closing block is irrelevant for retail consideration — those were institutional closes of pre-existing positions. The only retail-adjacent piece is the new 10:04 structure, and even that requires careful analysis. The three new legs cannot simply be copied at small scale without addressing the naked short call exposure.

Conservative: The "Stock + Defined Stop" Hold

Play: Buy shares if CDNS holds above $320 through the week

Rationale:

• The Q1 earnings overhang is cleared — revenue beat, backlog record, guidance raised on the top line
• $320 gamma support is solid; holding here means institutional support is active
• With 22 of 31 analysts at Buy and average PT of $377 per MarketBeat, ~17% upside is the Street consensus — the fundamental story remains intact
• Entry here ($320–$325) provides a natural risk level at $300 (gamma floor + 8.5% below entry = defined risk even on stock)
• Mark the calendar: Q2 earnings in late July is the next binary event — plenty of time to hold before then

Simple version: Buy 100 shares of CDNS near $320–$323 with a risk level at $299. Target: $340–$377 (consensus PT) over 2–4 months.

Risk level: Moderate | Skill level: Beginner-friendly

Balanced: The Retail-Friendly Bull Call Spread

Play: The only retail-friendly element of today's institutional flow is the $350/$380 bull call spread directional bet. A scaled-down version using a tighter spread is the cleanest replication:

Structure:

• Buy 1 Jun 2026-06-18 $350 call
• Sell 1 Jun 2026-06-18 $370 call

Why this works:

• The $350/$370 spread targets the same directional move as the institutional BTO buyer but with completely defined and reduced risk — no naked short exposure
• Estimated net debit: ~$5–8 per spread (vs. $14.33 for the naked long call alone) — the short $370 call finances roughly half the cost
• Max profit: $20 per spread if CDNS trades above $370 by June 18 (that is a 12.6% rally from current $327)
• Max loss: the net debit paid (~$5–8) — completely defined, no margin requirement for the spread
• Breakeven: ~$355–358, requiring CDNS to rally about 8–10% in 51 days
• Do NOT attempt to replicate the STO $380 naked short call leg — that requires substantial margin and carries theoretically unlimited loss potential without an underlying hedge. The retail version of this trade stops at the defined bull call spread.

Position sizing: 2–5 spreads per $10,000 of capital at risk. Risk only what you can afford to lose entirely.

Risk level: Moderate (defined max loss) | Skill level: Intermediate

Why You Should Not Copy All 6 Legs

The 09:32 legs are already closed — they no longer exist as positions to replicate. The 10:04 STO $380 naked call is the most dangerous leg: 10,000 contracts sold against only 24 prior OI, with a Z-score of 3,456. The institution running this almost certainly holds underlying CDNS stock or a long-dated call hedge to offset the short $380 call exposure. Without that hedge, the short call carries theoretically unlimited loss potential on a sharp upward surprise (e.g., a takeout bid or explosive AI capex announcement). This leg is not replicable for retail without significant margin accounts and sophisticated risk management capability.

---

⚠️ Risk Factors

Here is what could go sideways:

• EPS guide cut is real, not a one-time item: The $0.28 Hexagon dilution hits every quarter of 2026. At 41x forward non-GAAP EPS ($7.90 midpoint), the stock has zero margin for execution hiccups. If Hexagon integration costs run higher than expected or accretion slips past 2027, valuation compression math gets ugly fast — even if revenue grows as guided.

• China is 13% of revenue with volatile policy: The July 2025 rescission of EDA export controls can be reversed on short notice. Cadence's $140M DOJ/BIS settlement in 2025 demonstrates the regulatory attention the company receives. A single trade policy headline could carve 5–7% off the top line and send the stock toward $290.

• Jun $350 BTO call needs a ~7% rally in 51 days: With CDNS at $327.65 at the time of entry, the $350 call requires approximately a $22–$37 move just to reach and exceed the breakeven zone. If the stock consolidates in the $320–$340 range, the Jun call expires at a total loss. The institutional structure survives this via the $18M STO credit; a retail trader buying just the long call in isolation absorbs the full $14.33/contract cost.

• The 09:32 block signals prior pain, not prior wins: The fact that the trader paid ~$19M to close the Sep short calls tells you those positions were losing — the calls had moved ITM as CDNS rallied. This is a reminder that even sophisticated institutional traders get caught on the wrong side of a move. The wind-down cost before the new trade even opens was ~$19M.

• Synopsys post-Ansys is a more formidable competitor: The $35B Ansys acquisition gives Synopsys multi-physics simulation capability Cadence didn't previously face head-on. If Synopsys's integrated offering wins incremental wallet share, Cadence's ~35% EDA market position faces margin pressure over the medium term.

• Hardware cyclicality after the "best hardware quarter ever": Management explicitly called Q1 2026 the best hardware quarter in company history. Hardware (Palladium, Protium) comps in H2 2026 and Q1 2027 will be very tough. If hardware revenue normalizes, the Street may read it as deceleration even if software/IP remains healthy.

• The $380 STO short call creates a liability event: The institution sold 10,000 Aug $380 contracts with only 24 prior OI. If there is a sharp upward surprise (a takeout bid, a massive AI spending acceleration headline) sending CDNS above $380 before August, the short call side generates large mark-to-market losses until closed. Without an underlying hedge, this is the position's primary tail risk.

• $8B backlog quality: With $4B expected to convert within 12 months per the Q1 press release, a single large customer push-out would be visible in book-to-bill and could reset growth expectations materially ahead of the Jul/Aug option expirations.

🎯 The Bottom Line

Here is the honest read on today's $56.5M in CDNS option activity:

This is a position reset, not a fresh bullish build. The 09:32 block paid ~$19M to close out three legs of a prior structure — two short September calls that had moved against the trader as CDNS recovered from its April lows through the $329 post-earnings level. Thirty-two minutes later, with a slightly cleaner price at $327.65, the trader deployed a new three-leg structure: long the Jun $350 call as the directional engine, short the Aug $380 call to collect $18M in premium and cap upside, and long the Jun $300 put as a protective floor.

What this tells us:

• The bullish thesis on CDNS was NOT abandoned — the trader immediately re-entered with new exposure rather than walking away after closing the painful short calls
• The new structure is more conservative than the old one: defined risk (long call + protective put), funded by a short cap (Aug $380 STO), with a tighter June expiration that resolves before the Q2 earnings binary event
• The 3,456x Z-score on the STO $380 Aug call is the standout data point — 10,000 contracts opened against 24 prior OI on a completely fresh strike, collecting $18M. This is one of the most unusual institutional prints of the year on CDNS
• The $300 protective put tells you the trader is not blindly bullish — they bought insurance against China export control risk, macro shock, and Hexagon integration disruption at exactly the level where gamma structure provides the most support

The net economics in plain language: The trader paid roughly $26M all-in to reset from the old Sep structure to the new Jun/Aug structure. The new position costs only ~$1.7M net to carry (Jun debit minus Aug credit) and will profit if CDNS can clear $350 before June 18. The $380 cap limits upside through August, but $380 is 17% above today's price — a level the options market itself assigns low probability of reaching by August.

If you already own CDNS:

• The Q1 print is a genuine positive: revenue beat, guidance raised on the top line, record backlog. The EPS cut is acquisition arithmetic (dilution from Hexagon), not operational deterioration
• Hold with a risk level at $300 (major gamma wall + where the institutional BTO protective put lives)
• The consensus analyst target of $377 from MarketBeat with 22 of 31 analysts at Buy gives you a 17% runway from here — the fundamental story is intact
• Mark your calendar: Q2 earnings in late July 2026 is the next major catalyst

If you are watching from the sidelines:

• The immediate post-earnings period (this week) is a reasonable entry window — the binary event is behind us, the stock held well (-1.48% AH on a solid quarter), and institutional buyers clearly re-engaged within 30 minutes of the open
• A pullback toward $310–$315 (secondary gamma support, ~3–4% below current) would offer better risk/reward for new entries
• The secular AI EDA tailwind is as strong as any in technology: every custom chip designed by every hyperscaler generates Cadence revenue. That story is multi-year and getting stronger.
• Do not ignore the valuation (~41x forward EPS) and China overhang — size accordingly

If you are considering the retail-friendly options play:

• The only piece worth considering is the Jun $350 / $370 bull call spread — not the naked long call, not the STO short call, not the closed BTC/STC legs
• Size for complete loss: the spread costs ~$5–8 per contract and expires worthless if CDNS does not reach ~$355–358 by June 18
• The institutional position required a $26M reset cost to get to this point; retail entries are cleaner and simpler by design — stick to the defined-risk spread

Final verdict: CDNS is the pick-and-shovel play on the AI chip design rush. Today's flow confirms the bull thesis remains alive — but it also shows the cost of carrying the wrong structure through a violent recovery rally. The trader paid $19M to close September short-call exposure that moved against them, then efficiently re-entered with a tighter June structure. The $8B record backlog, the NVIDIA partnership escalation, the TSMC N2/A16 IP positioning, and the ChipStack/AgentStack AI productivity claims combine into one of the strongest secular setups in technology. The Hexagon EPS headwind is real but temporary; the backlog conversion and agentic-AI tailwinds are structural. With shares at $323 against a $377 consensus target, the risk/reward is favorable — respect the $300 floor, understand what you actually own in the options position, and let the backlog convert.

This is a roll, not a revelation. The thesis did not change. The structure did.

This analysis is for educational purposes only and does not constitute financial advice or a recommendation to buy or sell any security. Past performance does not guarantee future results. The unusual option flow described reflects the activity of one or more unknown market participants whose objectives, hedging needs, and portfolio context may differ significantly from a retail trader. The multi-leg structure described involves short option positions (the STO $380 call) that require margin, specific broker approval levels, and sophisticated risk management capabilities. Always conduct your own research and consult a licensed financial advisor before trading. Selling uncovered call options carries theoretically unlimited loss potential. The BTC/STC legs described in this analysis represent closing transactions on previously existing positions — they are not new directional bets and should not be interpreted as such. Options can expire worthless, resulting in total loss of premium paid.
