ASML Flow Report

Analysis based on market close April 2, 2026

Flow Verdict

Confidence:

7 / 10

base 5; +1.5 strong put OI dominance (P/C OI 1.40) & negative GEX; +0.5 spot below max pain; +0.5 high IV regime; -0.5 net premium positive but skewed

Watch next session: Flow around $1245 PUT OI cluster for support test; Net premium direction excluding far OTM calls; Any call buying in the $1320-$1350 zone

Flow Summary

Net premium: +$28.2M (mixed signal - heavily skewed by far OTM calls)

P/C volume ratio: 1.54 — strong put-dominant volume

P/C OI ratio: 1.40 — strong put-dominant positioning

The flow picture remains bearish. Despite a positive net premium, it is entirely driven by massive, non-directional premium in far OTM calls (e.g., $340). Volume and open interest are decisively put-heavy, and the negative GEX regime reinforces a pro-cyclical, trending bias to the downside. Spot is trading below all near-term max pain levels.

Notable Prints

ASML 4/2/26 $1300 Put

Vol: 720

OI: 347

Vol/OI: 2.1x

IV: 16.3%

Notional: ~$936K (720 * $1300)

Intent: Near-term directional hedge or speculation

Dual read: Bought (bearish bet for drop below $1300) or sold (premium sale at perceived support)

Read-through: With expiry in 0 days and spot at $1317, this is a bet on a last-minute move below $1300. The low IV (16.3%) suggests these were likely bought cheaply as a directional punt or protective hedge for a portfolio long. Adds to the immediate defensive tone.

ASML 4/24/26 $790 Put

Vol: 527

OI: 250

Vol/OI: 2.1x

IV: 103.2%

Notional: ~$416K (527 * $790)

Intent: Volatility/Yield play (likely short put)

Dual read: Sold (premium collection on extreme skew) or bought (deep, expensive protection)

Read-through: Extremely high IV (103.2%) and a strike ~40% below spot make this a classic premium sale candidate. This is not a -40% directional bet but a yield or tail-risk hedging structure. It's noise for spot direction.

ASML 8/21/26 $570 Put

Vol: 360

OI: 128

Vol/OI: 2.8x

IV: 69.8%

Notional: ~$205K (360 * $570)

Intent: Long-dated tail-risk hedge or spread leg

Dual read: Bought (deep, long-term protection) or sold (yield generation on far skew)

Read-through: Strike is ~57% below spot, expiring in ~5 months. The elevated IV (69.8%) suggests this is likely part of a structured hedge or a yield-generating short put. While sizeable in volume, its deep OTM nature dilutes its directional signal for near-term spot.

ASML 4/10/26 $1390 Call

Vol: 202

OI: 112

Vol/OI: 1.8x

IV: 48.2%

Notional: ~$281K (202 * $1390)

Intent: Upside lottery ticket or spread leg

Dual read: Bought (speculative bet on a ~5.5% rally) or sold (premium sale against a call spread)

Read-through: This is the only notable call activity in the unusual flow list. With IV slightly below the term structure average for its expiry, it leans toward being bought. However, its size is modest compared to the put flow, and it's OTM, suggesting it's speculative rather than a core bullish position.

Institutional Positioning

Call additions: Minimal near spot. Large premium in far OTM calls ($340, $770) continues to skew net premium but is non-directional.

Put additions: Major OI clusters remain at $1245P (2,037 OI) and $1075P (1,943 OI), establishing clear support levels and negative gamma.

GEX/DEX consistency: Yes — Negative GEX (-$4.4M) aligns with put-heavy OI, creating a pro-cyclical (trending) regime. Dealers are short gamma and will hedge by selling into weakness.

OI clusters: Major put walls at $1245 (2,037 OI) and $1075 (1,943 OI). Call walls are less concentrated; $1400C (1,038 OI) and $2180C (1,734 OI) are notable but far from spot.

Hedging evidence: Strong evidence of medium-to-long term hedging via deep OTM put OI clusters ($980P, $800P, $600P). The $1245P cluster is the critical near-term hedge and gamma flip level.

Max pain context: Spot ($1317.23) is below nearest expiry max pain ($1350 for 3/27, $1340 for 4/2). The max pain trend is falling over time ($1350 → $1280), suggesting gravitational pull is to the downside toward the $1245 gamma flip.

Signal vs Noise

~Massive net premium from $340/$770/$750 calls is noise — these are far OTM speculative positions, likely part of complex multi-leg strategies or volatility plays, not directional bets.

~$790 Put (4/24) with 103% IV is a volatility/yield play (likely a short put), not a -40% directional bet.

~The elevated P/C ratios (1.54 volume, 1.40 OI) are the stronger, cleaner signal than the skewed net premium figure.

~Some of the longer-dated, deep OTM put volume (e.g., $570P, $910P) could be overwriting (selling puts for income) or part of defined-risk spreads, diluting their bearish directional intent.

Key Conclusions

⚠️Conflicting Premium vs. Positioning: Bullish net premium is a mirage created by far OTM calls. Volume, OI, and GEX are unanimously bearish.

🛡️Critical Gamma Level at $1245: This is the estimated flip point and a major put OI cluster. A break below accelerates negative dealer hedging and selling.

📉Defensive Posture Intact: P/C OI of 1.40 and negative GEX (-$4.4M) show institutions remain positioned for downside or are heavily hedged.

🎯Max Pain Gravity is Down: Spot below all near-term MP levels with a falling MP trend supports a drift toward $1300 and the $1245 gamma zone.
