MSFT Flow Report

Analysis based on market close April 9, 2026

Flow Verdict

BiasNeutral-to-Bearish
Confirmation: Net premium remains negative (puts dominate) into tomorrow's expiries and $370-$375 prints accelerate, while spot drifts toward $370
Invalidation: Net premium flips materially positive (>+$200M), P/C volume rises above 1.1, or dealers unwind GEX (GEX drops toward zero)
Confidence:
6 / 10
base 6.0; +0.0 (use pre-computed base); -0.5 heavy net premium into puts (-$599.4M); +0.5 positive GEX pinning

Watch next session: Expiry flow at $370/$375 (4/10–4/13): continued high volume in 367.5–375 strikes; Net premium change (currently -$599.4M) — any flip or large call-heavy block

Flow Summary

Net premium: -$599.4M bearish (heavy put premium)

P/C volume ratio: 0.72 — modest call tilt by volume, not extreme

P/C OI ratio: 0.45 — call-heavy OI footprint (longer-dated call concentration)

Today’s flow is mixed: intraday volume shows big activity on both near-term calls (367.5–375) and large put prints into expiries, producing conflicting signals. Net premium strongly negative implies institutional put buying (bearish protection), but dealer GEX is +$74.8M and near-term call OI clusters (380/390/400) create pinning pressure around $370–$380, so the path is neutral-to-bearish with pinning risk into expiries.

Notable Prints

#1
MSFT 2026-04-10 $375.00 Call
Vol: 33,992
OI: 4,677
Vol/OI: 7.3x
IV: 30.6%
Notional: ~$5.17M
Intent: Short-dated directional call buying or expiry hedged dealer flow (bullish/rebalancing)
Dual read: Aggressive buy of calls (bullish) OR dealer/backspread hedging and overwriting (neutral)

Read-through: Large call demand into 4/10 increases short-dated pin pressure toward $375; supports pinning thesis despite net put premium.

#2
MSFT 2026-04-10 $367.50 Put
Vol: 14,366
OI: 1,242
Vol/OI: 11.6x
IV: 30.9%
Notional: ~$746k
Intent: Near-term downside hedging / directional put buying into expiry
Dual read: Bought puts (protective/bearish) OR closing/rolling of short positions (less likely given net premium)

Read-through: Very large volume vs OI at an ITM/near-ATM put suggests institutional protection for exposures into 4/10; this is a clear bearish hedge signal that helps explain the large negative net premium.

#3
MSFT 2026-04-15 $365.00 Put
Vol: 4,155
OI: 167
Vol/OI: 24.9x
IV: 26.6%
Notional: ~$814k
Intent: Opening protective puts (directional protection) or structured roll into 4/15
Dual read: Fresh protective put buying (bearish hedge) OR spread leg of a larger structure (collar) — but size vs OI points to fresh buys

Read-through: Significant relative trade size at $365 into 4/15 reinforces protective put accumulation beyond the immediate expiry, extending downside concern into the next weekly.

#4
MSFT 2026-04-13 $375.00 Call
Vol: 4,556
OI: 355
Vol/OI: 12.8x
IV: 23.6%
Notional: ~$1.24M
Intent: Short-dated bullish call buys or delta-hedged structures ahead of 4/13 expiry
Dual read: Bullish directional buys OR market-makers selling calls and hedging into expiration (pinning)

Read-through: Adds to the short-dated call demand picture; supports dealer hedging flows that can stabilize price around $375.

Institutional Positioning

Call additions: Notable call concentration in near-term strikes $375–$380 (large 4/10 and 4/13 call prints) and heavy long-dated OI concentrated in $400–$525 calls per Top OI strikes (structural call exposure).

Put additions: Significant fresh put demand at near-term strikes $367.50 and $365 across 4/10–4/15, plus sizeable premium flows showing large put notional at far strikes in the top premium flow table (450–490 puts) — indicative of portfolio protection or tail hedges.

GEX/DEX consistency: Yes — GEX is +$74.8M (dealers long gamma) which aligns with the pinning signatures at $375–$380 despite heavy put premium; dealer positioning supports price stabilization within the EM guardrails.

OI clusters: Near-term call OI clusters: $380.00 (9,431), $390.00 (8,701), $400.00 (8,404) — these form a call-side resistance/pin zone; Put OI clusters: $370.00 (4,956), $365.00 (4,522), $360.00 (3,844) create a support band near-term.

Hedging evidence: Clear evidence of protective put buying into the 4/10–4/15 expiries (367.5/365 prints) and potential longer-dated tail hedges (large premium put totals at 450–490 strikes); limited evidence of systematic collars in the near-term chain but spread activity could be underlying some prints.

Max pain context: Max pain pins at $370 (4/10) and $375 (4/13) match the concentration of near-term flow and GEX pin magnets; dealers are positioned to pin price between $370–$380 over the coming expiries.

Signal vs Noise

~Many large prints are clustered around expiries (4/10, 4/13, 4/15) — expiry-driven hedging and gamma-related flows likely dominate short-term prints.
~Top premium flow shows massive put premium at high strikes (e.g., $490/$480/$460) — likely portfolio tail protection or institutional insurance (not typical directional bet on spot moving to those strikes).
~High call OI at $400–$525 is structural (long-dated) and represents dealer inventory and long-call selling/overwriting dynamics more than intraday directional intent.

Key Conclusions

⚖️Mixed signals: large near-term put buying (net premium -$599.4M) vs strong positive dealer GEX (+$74.8M) producing pinning around $370–$380
📌Pin zone to watch: $370–$380 (Max Pain & GEX concentration at $375/$380). Short-dated expiring flow will likely keep price contained here near-term.
🐻Put-heavy activity at 4/10–4/15 (367.5, 365 strikes) reads as institutional downside protection — skew towards bearish hedging despite call volume.
🛡️Large long-dated call OI ($400–$525) suggests structural call exposure; these strikes create a long-term resistance band and can keep upside capped absent strong buyflow.
👀Watch net premium trajectory and 4/10 prints: continuation of heavy put premium vs accelerating call buys will determine whether pinning holds or a short squeeze emerges.
