🔄 TSM $101M Was a FULL UNWIND of Bullish Exposure, NOT a Fresh Bear Call Spread — Both Afternoon Legs CLOSED Per 6/2 OI

📅 June 1, 2026 | Last updated: 2026-06-02 | 🤝 Block Cross + Multi-Leg Auction Detected

Resolved by next-day OI (2026-06-02): The morning STC read holds as confirmed. The afternoon trade was NOT a fresh bear call spread being opened — the 6/2 OI snapshot shows both the $430C and $510C Sep-18 strikes shrank by ≈15,000–16,000 contracts, proving the desk was previously LONG the $430C and SHORT the $510C (a bull call spread). Today's SELL $430C / BUY $510C closed that prior bullish structure. The full two-trade picture is a complete unwind of TSM bullish options exposure — not a directional flip from long to short. See the ✅ RESOLVED OI box below.


🎯 The Quick Take

A major institutional desk executed two separate, strategically linked trades in Taiwan Semiconductor (NYSE: TSM) on June 1 — and the next-day OI snapshot tells us the corrected story. This morning at 09:57, they sold 5,000 TSM Aug-21 $340 Calls for ≈$50M: an STC profit-take on a deep-ITM long after TSMC's 124% rally, confirmed by OI. Then at 13:04, the same-or-similar desk printed what initially looked like a new 17,000-spread bear call spread on Sep-18 — SELL $430C / BUY $510C for a $51M net credit. The 6/2 OI snapshot inverted that read: both strikes shrank, not grew, proving the desk was CLOSING a prior bull call spread (long $430 / short $510), not opening a new short position.

Total net premium received across the day: ≈$101M. But the correct read is a full bullish de-risk, not a rotation to neutral-to-short. There is no new short call cap on the books. The desk walked away from TSM bullish options exposure entirely — ahead of TSMC's June 6–10 monthly revenue print, July 16 Q2 earnings, and the broader AI cycle.

Three-sentence interpretation:

The morning STC on the Aug-21 $340C holds exactly as written: OI fell ≈4,037 (consistent with 5,000 SELL into ≈5,209 remaining OI after the 5/29 tranche), confirming the desk closed the last leg of its deep-ITM long.

The afternoon trade is the inversion: rather than OI rising ≈17,000 on the $430C (which would have confirmed a new short call being opened), OI fell ≈15,888 — meaning the desk already held a LONG position in the $430C Sep-18 strike, and today's SELL closed it. Simultaneously, the $510C BUY caused OI to fall ≈14,525, meaning the desk already held a SHORT position in the $510C Sep-18 — and today's BUY closed it. Together that is the unwind of a prior bull call spread: long the $430C / short the $510C, a defined-risk bullish structure with a maximum payoff at $510+.

The combined result of both trades is a full unwind of TSM bullish options exposure. The desk is now flat on these three structures; there is no new short call capping upside, no new bear spread in place, and no directional signal about what they think TSM does next — only that they chose to zero out the prior bullish book on June 1.


🏢 Company Overview

Taiwan Semiconductor Manufacturing Company (NYSE: TSM) is the world's largest dedicated semiconductor foundry — the single most critical chokepoint in the global AI-chip supply chain. Every leading-edge chip from NVIDIA, Apple, AMD, Qualcomm, and Broadcom is built at TSMC's fabs.

  • Sector: Information Technology / Semiconductors (Pure-play foundry)
  • Exchange: NYSE (ADR)
  • Market Cap: ≈$2.2 trillion — one of the five largest companies in the world (Yahoo Finance, companiesmarketcap.com)
  • 52-week range: $192.20 – $446.68 (intraday high set June 1)
  • 2026 YTD performance: ≈+49% (Bloomberg)
  • 52-week performance (from ≈$192 low): ≈+124%

TSMC's 2026 run is built on real fundamentals: Q1 2026 net income surged +58.3% YoY, the N2 (2nm) node entered volume production, CoWoS advanced-packaging capacity is being quadrupled to handle AI-accelerator demand, and a U.S.-Taiwan trade deal locked in a 15% tariff ceiling. By afternoon on June 1, TSM had rallied another ≈$16 from the morning to ≈$446.68 — setting a new intraday all-time high. Which is precisely when the second trade happened.


💰 The Trades

Trade 1 — Morning STC: Ringing the Register on a Deep-ITM Long ✅ CONFIRMED

Plain English: An institution that owned TSM Aug-21 $340 Calls — bought when TSM was meaningfully lower — sat on ≈$90 of pure intrinsic profit per contract with TSM at $430.85. At 09:57 they crossed 5,000 contracts for ≈$50M. This is the second tranche of a tranched exit: open interest on this exact contract had already dropped −4,999 contracts (from 10,208 to 5,209) on the 2026-05-29 OPRA morning snapshot before June 1's trade. The 6/2 OI snapshot confirms: OI fell a further −4,037 (toward 1,172), fully consistent with the 5,000-contract SELL closing out the remaining long. This STC read is confirmed.

Trade 2 — Afternoon Bull Call Spread UNWIND: Closing a Prior Bullish Position ✅ INVERTED

Plain English (corrected): Four legs, two per side, printed at exactly 13:04:38. The desk SOLD 27,000 Sep-18 $430 Calls collecting ≈$100.74M, and simultaneously BOUGHT 25,600 Sep-18 $510 Calls paying ≈$49.71M. Net: ≈$51M credit received. On June 1 this looked like a new bear call spread being opened. The 6/2 OI snapshot inverts the read entirely: the $430C OI fell ≈15,888 (not rose ≈17,000), and the $510C OI fell ≈14,525 (not rose ≈17,000). Both strikes shrank. The desk was previously LONG the $430C and SHORT the $510C — a prior bull call spread (maximum payoff if TSM reaches $510+) — and today's trade closed that entire structure.

🤓 What This Actually Means — Plain English

Let's decode both trades and the corrected story they tell together.

Part A — The morning STC ($50M): Profit-taking on a deep-ITM long — CONFIRMED

The morning SELL is STC — Sell to Close. The desk owned Aug-21 $340 Calls and is selling them at a profit with TSM at $430.85. Three reasons we were confident before, now confirmed by OI:

  • OI already collapsed before June 1. OI on the Aug-21 $340C dropped −4,999 on 5/29 — the desk was already exiting last week. June 1 finished the job. The 6/2 OI confirms OI fell a further −4,037 toward 1,172.
  • Strike geometry makes no sense for a new short. Why would any rational desk write a new naked short call at $340 when TSM is at $430.85? That position would be ≈$90/contract underwater immediately. The only rational SELL at $340 is an existing long taking profit.
  • Block cross at near-mid: The ≈27% NBBO aggressor reading is consistent with a willing, orderly seller in a negotiated block — not someone urgently placing a new speculative short.

The desk likely bought these calls when TSM was in the $200s–$300s. With TSM at $430, the calls carry ≈$90 of intrinsic value. Across both tranches (5,000 on 5/29 + 5,000 on 6/1), the desk has exited ≈10,000 contracts of the original 10,208 OI. This position is fully unwound.

Part B — The afternoon bull call spread unwind ($51M net): Closing a prior bullish structure — INVERTED

A bull call spread (also called a long call vertical) works like this:

  • You BUY a call at a lower strike — here the desk previously bought the $430C. You pay net premium upfront, and you profit as TSM rises above $430. This is the "long" leg.
  • You SELL a call at a higher strike — here the desk previously sold the $510C. You collect premium to help offset the cost of the long $430C, but you cap your maximum gain at $510.

The net result of the prior bull call spread: the desk was positioned to profit if TSM rose above $430 toward $510, with maximum payoff if TSM hit $510 or above by September 18. That is a bullish structure — not a neutral or bearish one.

Today's trade (SELL $430C + BUY $510C) is the mirror image — the exact combination that closes a bull call spread. The 6/2 OI confirms it: both legs shrank rather than grew.

Why the closing trade looks identical to opening a bear call spread on the tape: This is the most important lesson in today's flow. On the raw tape, "SELL $430C + BUY $510C for a net credit" looks exactly the same whether the desk is (a) opening a new bear call spread or (b) closing an existing bull call spread. The trade condition codes, the prices, the aggressor levels — all identical. The ONLY thing that disambiguates them is the next-morning OPRA OI snapshot. If OI rises on both legs: new opens (bear call spread). If OI falls on both legs: closing existing positions (bull call spread unwind). The tape alone cannot tell you which is which. This is why the come-back-tomorrow OI check exists and why it is mandatory, not optional.

The desk received ≈$51M of net credit to close the spread. Whether that represents profit or a loss on the original bull call spread depends on what they originally paid to open it — OPRA cannot tell us the original cost basis. What we know: with TSM at $446.68 on June 1, the $430C carried ≈$16.68 of intrinsic value as an ITM call, and the $510C was ≈$63.32 OTM. The spread's value had expanded from its original opening: the $430C had appreciated substantially as TSM rallied, while the short $510C had also gained value (liability to the desk). The net $51M credit received to close suggests the structure had meaningful remaining value — a disciplined exit ahead of Q2 earnings uncertainty rather than a forced stop-out.

Part C — The combined desk story: A full bullish de-risk (corrected)

Here's the corrected insight that matters: this desk did TWO closing trades on TSM June 1, and together they are a complete unwind of TSM bullish options exposure:

  1. Morning STC: Closed a winning outright bullish long (the deep-ITM Aug-21 $340 calls that profited from the 124% rally). Banked ≈$50M in proceeds, largely representing crystallized profit.
  2. Afternoon bull call spread close: Closed a prior bullish Sep-18 structure (long $430C / short $510C) for ≈$51M net credit. This was also bullish exposure, now fully unwound.

Before June 1: the desk held two separate bullish structures — (1) outright long deep-ITM $340C (Aug-21), and (2) a bull call spread (long $430C / short $510C, Sep-18).

After June 1: the desk holds zero TSM bullish options exposure (at least from these structures).

That is a full de-risk, not a rotation to neutral-to-bearish. There is no new short call left on the books to cap the stock. The desk is flat TSM options exposure (for these positions) going into the June 6–10 monthly revenue print and the July 16 Q2 earnings. They could re-enter long, they could initiate a short, or they could stay flat. The tape tells us what they removed; it does not tell us what they intend to do next.

The sentiment read remains meaningful — a desk that held both an outright long and a bull call spread on TSM chose to zero both positions at a new all-time high, ahead of major catalysts. That is a disciplined "take the money off the table" decision on AI-chip bullish exposure. It is NOT a bet that TSM falls.


📈 Technical Setup / Chart Check-Up

YTD Performance Chart

TSM YTD

TSM has been on a historic run in 2026 — up ≈+49% YTD and ≈+124% off the 52-week low of $192.20. By the afternoon of June 1, the stock had pushed to a new intraday all-time high of ≈$446.68. The desk's decision to unwind both bullish structures at or near those all-time highs is a disciplined profit-management decision — not a prediction of imminent decline.

Key chart observations:

  • New all-time highs on June 1: TSM set fresh intraday highs twice — ≈$430.85 in the morning and ≈$446.68 in the afternoon. Both trades occurred at or near those intraday extremes.
  • Clean uptrend: The YTD structure is a series of higher highs and higher lows driven by earnings beats and AI demand confirmation.
  • The $430 level is a key gamma wall (see below) that the afternoon rally pushed through — having closed the $430C long, the desk no longer has direct mark-to-market exposure to this level.

Gamma-Based Support & Resistance Analysis

TSM Gamma S/R

The gamma exposure map (from gex.json, TSM current price ≈$442.76) shows how market-maker hedging will shape near-term price action. With the desk now flat TSM options (for the unwound structures), the gamma levels are most relevant for any new positioning:

Support Levels (Put Gamma Below Price — where dealers buy dips):

  • $440 — Immediate support, 5.87B total GEX, Strong. Just below current price; first structural buying zone.
  • $430 — Key support. 8.58B total GEX, Strong. Strong call gamma (7.82B) here means dealer hedging creates systematic buying at $430. The desk no longer has a short call here, so a rally through $430 no longer costs them; a decline toward $430 no longer benefits them via their (now-closed) short $430C.
  • $420 — Secondary support, 7.08B total GEX, Strong. A 5% pullback from current levels.
  • $400 — Major structural floor, 16.17B total GEX — the largest single strike in the chain. Both call (7.82B) and put (8.35B) gamma are nearly balanced here.

Resistance Levels (Call Gamma Above Price — where dealers sell rallies):

  • $450 — First overhead resistance, 6.51B total GEX, Strong. Only ≈+1.0% from current ≈$446 price.
  • $460 — Moderate resistance, 2.39B total GEX.
  • $470 — Extended upside, 2.12B total GEX.
  • $510 — The formerly short call strike. 2.70B total GEX. The desk no longer holds a short call here; this gamma level is relevant to the broader market structure but is no longer a direct liability or profit level for this desk.

Net GEX Bias: Bullish — call gamma dominates across the chain above the $400 structural floor.

Implied Move Analysis

TSM Implied Move

The options market is pricing in meaningful volatility over TSM's key catalyst windows:

TimeframeExpiryImplied MoveRange
WeeklyJune 5, 2026±$26.81 (±6.05%)$416.49 – $470.11
Monthly OPEXJuly 17, 2026±$80.46 (±18.15%)$362.84 – $523.76
Sep-18 Triple Witch (former spread expiry)September 18, 2026±$124.01 (±27.97%)$319.29 – $567.31
Aug-21 OPEX (morning trade's former expiry)August 21, 2026$338.65 – $547.95

The ≈±28% Sep-18 implied move (upper range ≈$570) is no longer directly relevant to the desk's exposure — they closed both legs. It is relevant context for anyone considering new positioning: the market is pricing a wide range of outcomes, and the July 16 Q2 earnings is the dominant binary driving that implied range.


🎪 Catalysts

Immediate Catalysts (Next 2 Weeks)

May 2026 Monthly Revenue: ≈June 6–10, 2026 — THIS WEEK

TSMC reports monthly revenue around the 10th of each month. The April 2026 print came in at NT$410.73B (+17.5% YoY, YTD Jan–Apr +29.9%) — the second-highest monthly total ever behind March's all-time record NT$415.19B. May's number (expected ≈SEC 6-K filing) is the most immediate data point — landing within 7–10 days and directly setting up the Q2 earnings narrative.

THE Dominant Catalyst: Q2 2026 Earnings — July 16, 2026

TSMC guided Q2 revenue of $39.0–$40.2B (≈+32% YoY at midpoint), GM 65.5–67.5%, OM 56.5–58.5%. Q1 2026 was already a blowout: $35.9B revenue, +58.3% net income, 66.2% gross margin — and management called AI/HPC demand "insatiable".

The fact that a sophisticated desk chose to unwind all TSM bullish options exposure on June 1 — ahead of this July 16 binary — is a notable sentiment signal. It does NOT tell us they expect a miss. It tells us they chose to take their gains (or manage their losses on the spread) rather than hold through the earnings uncertainty.

Structural / Multi-Year Catalysts

  • CoWoS capacity quadrupling to ≈130,000 wafers/month by late 2026 — AI packaging bottleneck locked in for NVIDIA, AMD, Google TPU, and Broadcom. (FinancialContent, Digitimes)

  • N2 (2nm) volume production, launched Q4 2025 — first N2 customers include Apple, AMD, NVIDIA, and MediaTek. "Faster than N3" ramp timeline (Tom's Hardware).

  • Arizona Fab investment at $165B — $20B additional approved May 12, 2026 (SEC 6-K, Tom's Hardware).

  • U.S.-Taiwan 15% tariff deal, February 2026 (NBC News).

  • Analyst consensus: Strong Buy, average 12-mo PT ≈$465 (high targets $500–$600) (MarketBeat, TipRanks).

Risk Catalysts

  • 🇨🇳 Geopolitical / Taiwan Strait tail risk — the perma-tail for any TSM position. Commerce Secretary Lutnick's goal of relocating 40% of Taiwan's chip supply chain to the U.S. was called "impossible" by Taipei.
  • 📉 AI demand normalization — ≈70% of Q1 revenue came from AI/HPC. Any hyperscaler capex pause would hit TSMC's most profitable mix directly.
  • 💰 CapEx dilution — 2026 capex guided at $52–56B. Arizona ramp cost creates margin pressure.
  • 📊 Valuation concentration — consensus PT of ≈$465 implies only ≈+4% upside from the June 1 close. After a 124% run, the stock is priced for near-flawless execution.

💡 Trading Ideas — For Four Different Investor Types

🎰 YOLO Trader — This Is Not a YOLO Entry Signal

Real talk: two institutional closing trades are the opposite of entry signals for momentum. The desk that held both an outright deep-ITM long and a bull call spread on TSM since earlier in the year has now taken profits (or managed losses) at an all-time high. Following a close is not the same as following an open. If you're looking for momentum, the ≈$14 June 1 afternoon rally from $431 to $447 already happened. There is no new position to ride-along with here.

📈 Swing Trader — July 16 Q2 Earnings Is THE Binary

The real opportunity is the upcoming catalyst sequence, not following today's closing trades:

  • June 6–10 (May 2026 revenue print): If you believe May AI/HPC demand held up, a call position expiring after the revenue print captures that readout. Consider a June 19 (Triple Witch) call spread — e.g., buy the $450C / sell the $470C, capturing upside if TSM breaks through $450 resistance on a strong revenue print. Cost: modest net debit, defined risk.
  • July 16 (Q2 earnings — the dominant binary): Both of today's unwound structures straddled Q2 earnings. A beat could send TSM toward $470–$500+; a miss could pull it toward $400–$430. The desk chose not to hold through that binary. If you have a view on Q2, consider a July 17 $440/$460 bull call spread — defined risk, captures a moderate post-earnings breakout if Q2 beats and TSM clears $460. If TSM misses and pulls back toward $430, the $400 gamma wall is the structural floor.

Position sizing: Binary catalyst bets should be 2–4% of your portfolio.

💵 Premium Collector — The Desk's Former Trade as Template (with the Correct Framing)

The afternoon trade was the unwind of a bull call spread that the desk had previously opened. If you want to understand what a bull call spread looks like in practice at institutional scale, this is the anatomy of the closing leg:

  • The desk originally held: LONG $430C (paid premium, benefited as TSM rallied through $430), SHORT $510C (collected premium, capped max gain at $510). Net: a defined-risk bullish structure with max payoff at TSM ≥ $510.
  • The June 1 unwind: SELL the $430C (receive ≈$59.26, recouping the long's appreciated value), BUY the $510C (pay ≈$29.24 to close the short liability). Net credit ≈$30.02/spread.

If you want to run a fresh premium-collection trade on TSM rather than following the close:

  • A new Sep-18 bear call spread (SELL $460C / BUY $520C) gives you premium collection with the short leg currently OTM and the spread's max-profit zone if TSM consolidates below $460 post-Q2.
  • Wait for post-Q2 IV crush (after July 16) — implied volatility will compress significantly, making new short-call legs cheaper to open at better strike levels.
  • The key risk: Q2 earnings is a massive binary. Opening a short-call structure before July 16 means you are long vega risk going into the event. Size for a 1-sigma upside move (≈$80 by the July 17 OPEX) when determining strikes.

🌱 Beginner — The Most Important Lesson: Closing a Bull Call Spread Looks Identical to Opening a Bear Call Spread on the Tape

This is the single most valuable concept from today's ≈$101M combined flow:

A bull call spread and a bear call spread are exact opposites in intent — but they produce identical-looking tape prints when closing one vs. opening the other.

  • A bull call spread = you BUY a lower-strike call and SELL a higher-strike call. You paid a net debit. You profit when the stock goes up past your long strike. You are BULLISH.
  • A bear call spread = you SELL a lower-strike call and BUY a higher-strike call. You received a net credit. You profit when the stock stays below your short strike. You are NEUTRAL-TO-BEARISH.

When the desk closed their bull call spread on June 1, the tape printed: SELL $430C + BUY $510C for a net credit. That is word-for-word identical to opening a new bear call spread. On the raw tape, no one can tell which it is.

The only way to know: the next-morning OPRA OI snapshot.

  • If OI on both legs RISES ≈17,000: it's a new opening (bear call spread). The desk just built a new bearish position.
  • If OI on both legs FALLS ≈15,000: it's a closing trade (bull call spread unwind). The desk just walked away from a prior bullish position.

On June 2, OI fell on both legs. Full stop: the afternoon trade on June 1 was the unwind of a prior bullish bet, not the opening of a new bearish one. There is no new short cap on TSM from this desk. The stock is not "capped at $510."

The practical takeaway: when you see a large options trade in the flow that looks like a new bearish structure, always check back the next morning before drawing conclusions. The trade that looks like aggressive new positioning is sometimes just a sophisticated desk closing out old exposure. OPRA is the only way to know.


⚠️ Honest Risk Assessment — What the Tape Proves and Cannot Prove

What the tape + 6/2 OI confirm:

  • ✅ Trade 1: 5,000-contract SELL of TSM Aug-21 $340C at ≈$100 (≈$50M). OI fell −4,037 to 1,172. Confirmed STC (closing a deep-ITM long). Two-tranche exit of 10,000 contracts total from the original 10,208 OI. Position fully unwound.
  • ✅ Trade 2: SELL 27,000 Sep-18 $430C (≈$100.74M collected) + BUY 25,600 Sep-18 $510C (≈$49.71M paid). Net credit ≈$51M. OI on $430C fell −15,888 (to 7,549); OI on $510C fell −14,525 (to 3,085). Confirmed closing of a prior bull call spread (long $430C / short $510C). Prior bullish structure fully unwound.
  • ✅ Combined result: Full unwind of TSM bullish options exposure across both structures. Net ≈$101M of premium received.
  • ✅ No new short call remains on the books from today's trades. There is no desk-imposed upside cap from this flow.

What the tape CANNOT prove:

  • Whether Trade 1 and Trade 2 are from the exact same account or two coordinated desks at the same firm. The circumstantial case is strong (same underlying, same day, complementary structures) but it is an inference.
  • The original cost basis of either structure. The Aug-21 $340C position was opened when TSM was presumably much lower — realizing substantial intrinsic profit. The bull call spread's original entry price and net debit are unknown; the ≈$51M closing credit could represent locking in a gain, covering a partial loss, or exiting at breakeven.
  • Whether the desk holds TSM common stock or other derivatives not visible in today's OPRA prints.
  • What the desk intends to do next — they could stay flat, re-enter long, initiate a short, or open a different structure. Today's trades tell us what they closed, not what they plan to open.
  • The July 16 Q2 earnings outcome — this is the dominant unresolved binary for TSM.

🎯 The Bottom Line (Corrected)

Here's the corrected deal: TSMC ran 124% on the most real AI-driven demand story in global semiconductors. On June 1, at a new all-time high of $446.68, a sophisticated institutional desk chose to take everything off the table — both an outright deep-ITM long (Aug-21 $340C) AND a bull call spread (Sep-18 $430C/$510C) that had been positioned for a TSM rally toward $510+. They received ≈$101M in net proceeds across the day.

This is not a directional flip. There is no new short position. There is no new upside cap. The desk is flat.

The corrected sentiment read: smart money that rode TSMC's bull run has chosen to crystallize its gains (and/or manage its losses on the spread) ahead of the June 6–10 monthly revenue print, the July 16 Q2 earnings binary, and the broader AI capex cycle. That is a meaningful signal — not "we're bearish on TSM," but "we've made our money on this specific bullish bet and are choosing not to hold it through near-term catalysts." Those are two very different things, and only the 6/2 OI snapshot disambiguates them.

If you own TSM long (stock or calls): Today's corrected flow is a neutral signal, not a caution signal. The desk removed bullish exposure; they did not add bearish exposure. The $430 gamma wall remains your structural floor. The July 16 earnings is the catalyst you need for the next leg up. Watch the June 10 revenue print as the earliest signal of whether Q2 is tracking the guided $39–40B range.

If you're watching from the sidelines: The upcoming catalyst sequence — May revenue in ≈9 days, Q2 earnings in ≈46 days — offers genuine directional clarity before you position. The Sep-18 implied move range ($319–$567) is enormous. A post-Q2-earnings entry at defined-risk levels will be far more informative than guessing direction today.

Mark your calendar:

  • 📅 ≈June 6–10 — May 2026 monthly revenue print
  • 📅 June 19 — Triple Witch OPEX
  • 📅 July 16 — Q2 2026 earnings (the dominant binary)
  • 📅 August 21 — Former expiry of Trade 1's underlying contract
  • 📅 September 18 — Former expiry of Trade 2 (fully closed; no desk exposure remains on these legs)

Final verdict: TSM remains the AI-chip infrastructure monopoly no serious tech investor can ignore. But June 1's ≈$101M of combined flow — correctly read after the 6/2 OI snapshot — tells you at least one institutional desk has finished its victory lap on TSM bullish exposure in its entirety: closed the outright long, closed the bull call spread, and walked away flat ahead of major catalysts. That is disciplined position management at a new all-time high. It is NOT a bet that TSM falls. Watch July 16.

Disclaimer: Options trading involves substantial risk of loss and is not suitable for all investors. This analysis is for educational and informational purposes only and does not constitute financial advice or a recommendation to buy, sell, or hold any security. Past performance does not guarantee future results. The STC read for Trade 1 was confirmed by the 6/2 OPRA OI snapshot (OI −4,037). The bull-call-spread-unwind read for Trade 2 was confirmed by the 6/2 OI snapshot (OI −15,888 on $430C, −14,525 on $510C). The original STO/BTO (bear call spread) interpretation from June 1 has been inverted and corrected. Max loss/profit figures in the "prior structure economics" table assume hypothetical positions held to expiration; in practice, institutional desks actively manage and roll positions. Always conduct your own research and consult a licensed financial advisor before making any investment decisions.
