Market Pulse
The market is splitting along a clean fault line: tariff fear vs. tariff beneficiary. Tonight's enriched scan picked up 44 signals — 32 bullish vs 12 bearish. On the surface that looks constructive, but the flow underneath tells a more complex story.
Bullish flow is concentrated in domestic industrials, defense, and shipping — names that benefit from trade barriers. Bearish flow is hammering consumer discretionary and tech names exposed to China supply chains. The smart money is repositioning portfolios around the tariff regime, not making broad directional bets.
AVGO is the headline — Broadcom reports after the bell and $755M in options flow shows institutions are hedging into the print. Meanwhile, COST and MRVL are getting aggressively sold. The theme is clear: if you're exposed to China, you're getting repriced.
Key Themes
🟢 Theme 1: The Tariff Winners — Domestic Industrials & Defense
Steel, shipping, and defense names are catching bids as tariff expectations firm:
- ZIM — Score 8. Israeli shipping giant ripped +5.2% with $9.3M in directional call flow at 85.5x C/P ratio across 20 strikes. Tariff-driven rerouting of global shipping lanes benefits ZIM directly. RSI 54 with room to run.
- MMM — Score 7. $9.9M directional calls. The "Bits to Atoms" rotation continues. Industrial cash flows over tech CAPEX.
- STLD (Steel Dynamics) — Score 7. +2.1% with $6.1M calls at 17.5x C/P ratio. Direct beneficiary of steel tariffs.
- RTX — Score 6. Defense giant with $151M call flow, 2.3x C/P, 52 strikes. Steady institutional accumulation.
🟢 Theme 2: Energy Refiners Still Running
The refiner trade from yesterday continues with fresh conviction:
- VLO (Valero) — Score 7. +4.2% to 52-week highs with $74M directional call flow at 4.3x C/P. 42 active strikes. Scotiabank raised EPS to $13.75 citing Venezuelan crude pivot and structural margin advantage.
- PSX — Score 7. Continuing from yesterday's all-time high breakout. $34M in calls.
🔴 Theme 3: Broadcom Earnings Hedge Wall
- AVGO — Score 7. BEARISH despite being +3.2% on the day. $755M total options flow with puts at 1.2x calls. $424M in unusual options activity across 97 strikes. This is the night's biggest single-name flow event. Institutions are hedging into tomorrow's earnings print with massive downside protection. $10B buyback announced but the flow says "show me the AI revenue."
🔴 Theme 4: China Exposure Getting Crushed
- COST (Costco) — Score 8. Highest bearish score of the night. -4.6% with $92M put flow at 2.7x C/P, 33 strikes, $59M UOA. Trump's tariff escalation hits Costco's import-heavy model directly.
- MRVL (Marvell) — Score 8. -19.5% after earnings miss. $348M put flow at 2.3x C/P, 57 strikes, $171M UOA. China revenue exposure + AI infrastructure spending uncertainty = institutional liquidation.
- FIVE (Five Below) — Score 7. -1.9% with $27M puts at 4.3x C/P. Dollar store model is heavily China import dependent. 15 active put strikes.
- CRM (Salesforce) — Score 6. $82M put flow. Enterprise software uncertainty continues.
🟢 Theme 5: Divergence Dip-Buys
Smart money buying calls into selloffs:
- MRVL — Despite the -19.5% carnage, $152M in CALL flow alongside $348M in puts. Someone is buying the dip at the $50 level across 75 call strikes. Classic divergence.
- NTNX (Nutanix) — -13.1% but bullish call flow. Score 6. Cloud infrastructure dip-buy.
- IOT (Samsara) — -9.1% but bullish. Score 6. IoT/fleet management dip-buy.

The Pattern Continues: Tariff Regime Trade
For the third consecutive session, the flow is telling one story: reposition around tariffs. Domestic industrials (STLD, MMM), defense (RTX), and shipping (ZIM) get directional call flow. China-exposed consumer and tech (COST, MRVL, FIVE) get put flow. Energy refiners (VLO, PSX) continue breaking out as a beneficiary of the supply chain reshuffling.
This is not a risk-on or risk-off market. It's a rotation market. The money isn't leaving equities — it's moving from one side of the tariff wall to the other.
Summary
Bias: Selective bullish on tariff beneficiaries, bearish on China exposure.
The AVGO earnings print tonight will set the tone. If they deliver on AI revenue expectations, the semiconductor complex gets a bid. If they miss (like MRVL), the hedging flow was right and the selloff accelerates. Watch the after-hours reaction — that's where the real signal lives.
ZIM and VLO are the cleanest conviction longs. COST and FIVE are the cleanest conviction shorts. Everything else requires navigating the tariff noise.
