MSTR Flow Report

Analysis based on market close April 9, 2026

Directional Theta Gang Flow Earnings Consensus

Flow Verdict

Confidence:

4.5 / 10

base 4.5; +1.0 GEX pinning (+$154.3M) supports pin; -1.0 net premium large negative (-$232.1M) adds ambiguity; -0.5 spot 3.9% above near MP

Watch next session: $132 call / OI / GEX concentration — dealers defending pin at $132; Any follow-through in 4/17 $136/$142 calls (repeat prints) or closing of large 4/10 ITM puts ($131/$129) ahead of expiry

Flow Summary

Net premium: -$232.1M (net premium negative, large put premium by notional but mixed by volume)

P/C volume ratio: 0.48 — call-dominant intraday volume

P/C OI ratio: 0.86 — mild call skew in open interest but not extreme

Intraday flow shows heavy call activity (low P/C vol) against a large negative net premium figure, producing a mixed picture. Dealers are long gamma (GEX +$154.3M) and positioned to pin the stock between $125–$135, while some sizable put notional and expiry hedging near 4/10 increases downside risk into expiry.

Notable Prints

MSTR 2026-04-17 $142.00 Call

Vol: 37,224

OI: 3,785

Vol/OI: 9.8x

IV: 61.7%

Notional: ~$3.39M

Intent: Aggressive directional call buying or call sweep accumulation into next-week expiry

Dual read: Bought calls (bullish directional) OR dealer selling/laying off into flow (neutral); size + vol/OI favors fresh buys

Read-through: Demand for upside exposure out to $142 (10% from spot) — pick-up in bullish positioning; likely contributes to dealer hedging short stock and thus positive GEX/pinning above spot.

MSTR 2026-04-17 $136.00 Call

Vol: 9,474

OI: 917

Vol/OI: 10.3x

IV: 61.2%

Notional: ~$1.90M

Intent: Directional call buys or call-heavy spread leg (vertical/ratio) into 4/17

Dual read: Fresh bullish exposure OR part of a structured spread (seller leg elsewhere); high vol/OI points to new position

Read-through: Reinforces bullish flow concentrated in the $132–$140 area; this print sits near a large call OI cluster and likely increases dealer short-delta/gamma hedging in that band.

MSTR 2026-04-17 $135.00 Call (block OI & volume)

Vol: 33,591

OI: 34,241

Vol/OI: 1.0x

IV: 61.6%

Notional: ~$7.86M

Intent: High-liquidity call accumulation and/or heavy positioning at key expiration; both directional buys and roll/maintenance of existing positions

Dual read: Could be fresh call buys (bullish) or rolling/adding to existing call exposure (neutral-to-bullish)

Read-through: This strike is the dominant call OI anchor (34,241 OI). Activity here materially shapes dealer hedging and creates a near-term resistance/pin target around $135.

MSTR 2026-04-10 $131.00 Put (ITM near-term expiry)

Vol: 3,035

OI: 152

Vol/OI: 20.0x

IV: 71.7%

Notional: ~$0.94M

Intent: Expiry-driven protective puts / short-covering ahead of 4/10

Dual read: Mostly defensive/roll/expiry behavior (buyers of protection) though could be directional put accumulation by a speculator

Read-through: High vol/OI and ITM status with 4/10 expiry points to near-term downside hedging — increases chance of pin-pressure or put unwind on expiry.

MSTR 2026-04-10 $129.00 Put (ITM near-term expiry)

Vol: 4,537

OI: 796

Vol/OI: 5.7x

IV: 70.9%

Notional: ~$0.91M

Intent: Short-term downside protection / expiry hedging

Dual read: Protective buying into expiry (likely) vs. short-spec put selling earlier being closed

Read-through: Adds to the picture of concentrated short-dated put demand around the current price — dealers may be long puts/short stock gamma-rehedging into expiry, boosting pin dynamics.

Institutional Positioning

Call additions: $125-$142 calls (notably heavy activity at $125, $132, $135, $136, and large unusual flow at $142) — roll/accumulation into 4/17

Put additions: Near-term protective/expiry puts concentrated at $128-$131 for 4/10 and structural longer-dated put OI clustered at $100 (28,106 OI) indicating tail protection held by institutions

GEX/DEX consistency: Yes — positive GEX (+$154.3M) aligns with heavy call volume and OI clusters in the $125–$135 band producing pinning behavior; DEX +49.4M shares consistent with dealer delta exposure

OI clusters: Largest call OI cluster: $135 (34,241 OI) with adjacent $136/$140 clusters; largest put cluster: $100 (28,106 OI) — creates a near-term magnet around $125–$135 and a structural floor influence near $100 for long-tail risk

Hedging evidence: Clear short-dated protective put buying into the 4/10 expiry (131,129,128 puts) and persistent deep-tail put OI at $100 suggests institutions maintain downside hedges; limited evidence of broad collar structures in near-term chains.

Max pain context: Near-term MP at $124 (4/10) shifts to $135 (4/17 & 4/24). Current spot ($128.86) sits between these pins; flows are consistent with dealers trying to squeeze spot toward the $132–$135 band for next-week expiries.

Signal vs Noise

~Multiple ITM/near-ITM 4/10 puts (e.g., $131, $129, $128) — likely expiry-driven hedging/rolls rather than fresh directional conviction.

~Very large notional entries in Top Premium Flow (e.g., $315, $210, $420, $950 listed) are far outside near-spot strikes and likely reflect institutional tail hedges, account-of-record reallocation, or data artifacts — treat as noise for short-term directional reads.

~High-volume at $135 call OI (33k vol / 34k OI) can be routine liquidity/position maintenance in a highly concentrated strike — interpret alongside vol/OI and adjacent sweep behavior before assigning pure directional bias.

Key Conclusions

🔁Mixed flow: call-dominant volume but large net negative premium (-$232.1M) — read as buying interest offset by heavy put notional and hedging.

📌Pinning dynamics: GEX concentration at $132, $129, $125 and large call OI at $135 make $125–$135 the active pin/resistance band into expiries.

🐂Bullish signs: concentrated unusual buying in 4/17 $136 and $142 calls suggests institutional upside exposure that will force dealer short-delta hedging (supports spot).

⚠️Watch expiries: heavy 4/10 ITM put activity ($131, $129, $128) is likely protective and can create intraday volatility around expiry; not necessarily a new bearish regime.

🧭Key levels to monitor — Support: $125.00, $129.00, $132.00. Resistance: $135.00, $136.00, $140.00 — all within ±10% of spot and tied to OI/GEX clusters.
