Flow Summary

Net premium: +$71.2M bullish

P/C volume ratio: 0.37 — extremely call-dominant

P/C OI ratio: 1.35 — put-skewed positioning

Notable Prints

#1
LLY 4/10 $1050 Call
Vol: 4,180
OI: 227
Vol/OI: 18.4x
IV: 38.7%
Notional: ~$3.8M
Intent: Fresh, aggressive directional call buying
Dual read: Bought to open (bullish breakout bet) or sold/written (neutral to bearish). High vol/oi and low IV relative to front week favor buyer.

Read-through: A bet on a >14% move higher in 10 days, targeting a breakout above the $1000-$1050 resistance zone. Size and strike suggest conviction.

#2
LLY 4/2 $1100 Call
Vol: 1,305
OI: 113
Vol/OI: 11.6x
IV: 75.0%
Notional: ~$1.2M
Intent: High-risk, high-reward directional lottery ticket
Dual read: Almost certainly bought (bullish). The 75% IV is expensive, making selling unattractive for such a low delta, far OTM strike.

Read-through: Pure speculation on a massive, >19% move higher in just 2 days. Highlights extreme bullish sentiment and risk appetite in the near term.

#3
LLY 4/10 $1000 Call
Vol: 1,975
OI: 183
Vol/OI: 10.8x
IV: 39.4%
Notional: ~$1.8M
Intent: Directional call buying targeting key resistance
Dual read: Bought to open (bullish). The $1000 strike is a major OI magnet (2,262 OI), and this flow adds to it.

Read-through: Strategic bet on breaking through the $1000 level within 10 days. Complements the $1050C flow, building a bullish ladder.

#4
LLY 4/2 $970 Call
Vol: 2,324
OI: 261
Vol/OI: 8.9x
IV: 46.9%
Notional: ~$2.1M
Intent: Near-term directional bet or gamma scalp
Dual read: Likely bought (bullish). With spot at $920, this is a 5.5% OTM bet in 2 days. High volume suggests active positioning for a quick move.

Read-through: Targets a move to the upper bound of the 2-day expected move ($961.87). Part of the concentrated front-week bullish activity.

Institutional Positioning

Call additions: Overwhelmingly in Apr'26 expirations ($945-$1100), focused on 4/2 and 4/10. Largest premium at $950C and $1000C.

Put additions: Minimal in flow. Long-term OI is heavily put-skewed (P/C OI 1.35), with large walls at $400P, $790P, and $600P.

GEX/DEX consistency: Mixed. Flow is wildly bullish, but GEX is negative (-$2.7M). This creates a pro-cyclical, trending regime: moves higher could accelerate (dealers short gamma), but a break lower could also snowball.

OI clusters: Major Call: $1000 (2,262 OI). Major Puts: $400 (3,177 OI), $790 (2,908 OI), $600 (2,106 OI). Spot is pinned between near-term call OI ($1000) and long-term put OI ($790-$400).

Hedging evidence: The massive, deep OTM put walls ($400, $600) are likely long-term portfolio hedges or tail-risk protection, not recent directional bets. Minimal near-term protective put flow observed.

Max pain context: Spot ($919.77) is precisely at the near-term max pain ($920 for 3/27, 4/10, 4/24). This pin is being challenged by aggressive call buying. The longer-term MP trend is falling ($920 → $890), aligning with the put-skewed OI.

Signal vs Noise

~The $1340 Put with net premium -$2.39M is a notable outlier but is likely a leg of a complex, far-dated structure (e.g., collar, ratio spread) given its extreme distance from spot (~45% OTM). Not a direct directional signal.
~High volume in front-week (4/2) calls includes gamma/scalping activity from dealers and fast money due to negative GEX, amplifying the bullish flow signal but adding volatility.
~The deep OTM put OI ($400, $600) is stale, long-term hedging and should not be conflated with recent directional sentiment.

Key Conclusions

🚀Explosive call buying dominates flow, with +$71M net premium betting on a near-term breakout.
⚖️Market is at a tension point: bullish flow & spot at max pain vs. negative GEX and long-term put walls.
🎯Key levels to watch: Upside break above $1000 confirms flow thesis; breakdown below $900 invalidates it.
