ASML put volume surges with heavy concentration at 1700 strikes, directionally bearish
ASML saw 1,699 option contracts trade with a heavy put skew — 1,394 puts to 305 calls (put/call ratio 4.57) and total premium of $15,392,297 — concentrated in 1700-strike puts across June and July expirations.
ASML registered unusually large, directionally bearish options activity during the morning session on 2026-06-03, with 1,699 contracts traded and total premium of $15,392,297.20. The flow was dominated by puts: 1,394 put contracts versus 305 calls (put/call ratio 4.57), driving a put-premium share of $12,845,678.00. Overall volume and premium were both elevated versus typical levels (volume vs. average 2.37x; premium vs. average 3.5x) and sit in the high percentiles (total volume percentile 94.7; total premium percentile 100.0), signaling unusually large and concentrated downside positioning.
The activity shows hallmarks of high-quality bearish flow. Two put series account for the bulk of the action: the 1700-strike puts expiring 2026-06-18 posted 749 contracts for $5,009,139.00 in premium, while the 1700-strike puts expiring 2026-07-17 contributed 459 contracts and $5,440,220.00 in premium. Those strikes are close to the underlying price of $1,714.62, with average absolute deltas around 0.44–0.46, indicating sizable directional exposure rather than deep speculative tail bets. Same-side tape shows 98 trades across 29 contracts totaling $12,845,678.00 in premium with a single trade max premium of $2,152,800.00, and sweep/block premium activity is elevated (sweep_block_premium_ratio 1.534 overall), consistent with large, aggressor-side execution.
Liquidity and volatility context do not suggest the activity is merely a reaction to illiquidity: average bid/ask spreads were modest (average_spread_pct 2.62; same-side average_spread_pct 2.31) and 67 unique contracts traded in 155 trades, indicating breadth of participation. Implied volatility remains elevated (IV30 49.33%; average IV about 54.15% in the chain) and the market’s 30-day expected move is roughly 8.47% (±$145.40), putting the 1700 strikes within a plausible move range to the downside. There is an upcoming earnings date on 2026-07-15, but the largest traded expirations include a mid-June and mid-July series rather than only the post-earnings date.
While the flow is clearly skewed bearish and shows institutional-size premium and same-side concentration, options flow does not disclose intent. The size, premium concentration, high percentile readings, and execution patterns together mark this as notable downside positioning in ASML rather than routine retail activity.
