Flow Verdict
Watch next session: New OI or premium accumulation at $695/$696 calls (near-term pin levels); Large executed put flow at $670-$680 that increases P/C premium or moves net premium toward neutral/negative
Flow Summary
Net premium: +$1.2B bullish
P/C volume ratio: 1.14 — small put-volume skew intraday but not extreme
P/C OI ratio: 2.35 — substantial put-heavy positioning in OI (structural bearish tilt in longer-dated strikes)
Notable Prints
Read-through: Large executed flow at the 692 call (ITM at spot) materially increases short-dated call exposure and forces dealers to buy delta — supports upside and short-term pin toward the 690-695 GEX cluster.
Read-through: Massive same-day call volume concentrated ATM amplifies dealer short-gamma; combined with positive GEX this increases pinning forces around $694-$695 intraday.
Read-through: Given the tiny last prices ($0.01-$0.02) and low IV, this looks like high-frequency expirational flow, increasing short-dated gamma exposures rather than building meaningful directional put protection.
Read-through: This print is more meaningful notional-wise vs the 4/14 tiny-last-price prints — if that flow continues it could represent real short-term downside hedging that would cap the upside pin.
Institutional Positioning
Call additions: Concentrated call premium and flow at $690-$695 (notably $690/$691/$692/$694) in near-term expirations — dealers are short gamma there and will buy delta into upside moves.
Put additions: Large structural put OI sits well below spot (notably $535, $520, $530, $590, $500 clusters) plus heavy premium at $650 puts (net -$37.35M), indicating institutions hold sizeable protective/long-put positions at lower strikes.
GEX/DEX consistency: Yes — positive GEX ($+1.6B) and DEX +294.8M shares are consistent with short-dated call dominance and pinning around $695; long-dated put OI creates a structural downside hedge but not immediate dealer-driven pressure.
OI clusters: Largest OI clusters are concentrated far below spot (e.g., $535 PUT OI=204,057; $520 PUT OI=202,356; $530 PUT OI=164,343) and near-spot call OI clusters at $686-$690-$695 (calls OI: $686=27,247; $690=20,332; $695=10,269). The nearest prominent pin/wall is the GEX concentration at $695 (+$413.0M).
Hedging evidence: Evidence of large-scale protective puts in longer expirations (OI mass at $500-$535-$650) and put premium at $650 suggests institutional downside hedging; limited evidence of widespread collars in the near-term aside from small protective put prints.
Max pain context: Max pain sits at $681 (flat across expirations). Spot is above MP by ~2% and flow shows dealer pinning forces (GEX) trying to hold spot up near ~$695 rather than drifting down to MP immediately.
