Ranked exposures

  1. ▼ OXY Occidental Petroleum — impact -79 · confidence medium · horizon immediate · 1st order
    Lower crude prices reduce Occidental’s oil revenue, restricting free cash flow for debt reduction and preferred redemption.
    Chain: sanctions relief returns Iranian barrels to market → global crude supply rises against flat demand → benchmark oil prices fall → Occidental realizes lower prices per barrel sold → free cash flow for debt paydown shrinks
    What would break the call: OPEC members cut output to offset Iranian barrels and crude prices hold above current levels.
  2. ▼ COP ConocoPhillips — impact -76 · confidence medium · horizon immediate · 1st order
    Crude price declines directly reduce ConocoPhillips’ realized production revenue and per share earnings across its upstream portfolio.
    Chain: Iranian export volumes re-enter legal channels → global supply balance loosens → Brent and WTI realizations decline → ConocoPhillips upstream revenue per barrel falls → earnings per share and buyback capacity shrink
    What would break the call: Iranian volumes return slower than announced and physical differentials keep realized prices near prior levels.
  3. ▼ XOM Exxon Mobil — impact -76 · confidence medium · horizon immediate · 1st order
    Returning Iranian supply depresses crude prices, reducing Exxon Mobil’s upstream revenue and cash flow.
    Chain: blockade ends and Iranian crude flows resume → seaborne supply increases into Asia and Europe → crude benchmarks move lower → Exxon upstream segment earnings decline → downstream gains only partly offset
    What would break the call: Refining and chemical margin expansion exceeds upstream loss and consolidated earnings guidance rises.
  4. ▼ EOG EOG Resources — impact -75 · confidence low · horizon weeks · 1st order
    EOG Resources generates less cash per barrel from its predominantly oil-focused shale development program.
    Chain: sanction relief adds global crude supply → oil prices decline across the strip → EOG oil weighted volumes realize less revenue → cash margin per barrel compresses → capital program returns weaken
    What would break the call: Natural gas and NGL price strength offsets the oil decline in EOG realized blended pricing.
  5. ▼ CVX Chevron — impact -74 · confidence medium · horizon immediate · 1st order
    An oversupplied crude market lowers Chevron’s realized prices, compressing upstream earnings and capital returns.
    Chain: Iranian barrels return to global trade → crude oversupply pressures benchmark prices → Chevron realized upstream prices fall → upstream segment earnings and cash flow decline → dividend and buyback coverage tightens
    What would break the call: Chevron raises production guidance enough that volume growth offsets the lower realized price per barrel.
  6. ▼ FANG Diamondback Energy — impact -74 · confidence medium · horizon weeks · 1st order
    Lower crude prices weaken Diamondback’s Permian realizations, reducing free cash flow and drilling returns.
    Chain: Iranian supply returns after blockade ends → WTI benchmark declines on surplus → Diamondback Permian realizations fall → free cash flow per share contracts → variable dividend and rig count decline
    What would break the call: Midland differentials narrow sharply and hedges lock realizations near prior levels through the quarter.
  7. ▲ DAL Delta Air Lines — impact +73 · confidence medium · horizon weeks · 2nd order
    Cheaper crude lowers Delta’s jet fuel expenses, expanding operating margins across its extensive flight network.
    Chain: Iranian crude returns and oil prices fall → refined jet fuel crack follows crude lower → Delta jet fuel cost per gallon declines → fuel expense line drops → operating margin expands
    What would break the call: Jet crack spreads widen on refinery outages and jet fuel prices stay flat despite cheaper crude.
  8. ▲ UAL United Airlines — impact +71 · confidence medium · horizon weeks · 2nd order
    Lower jet fuel prices reduce United’s largest variable cost, expanding profitability across its long haul network.
    Chain: global crude supply rises on sanctions relief → jet fuel prices track crude lower → United fuel expense per gallon falls → long haul trip costs decline → operating margin and earnings rise
    What would break the call: Industry capacity expands on cheap fuel and fare declines erase the unit cost savings.
  9. ▲ VLO Valero Energy — impact +71 · confidence medium · horizon weeks · 2nd order
    Cheaper heavy sour crude lowers Valero’s refinery feedstock costs before refined product prices adjust, widening refining margins.
    Chain: Iranian heavy sour barrels return to market → heavy sour discounts to Brent widen → Valero feedstock acquisition cost falls → refined product prices lag crude declines → refining margin per barrel widens
    What would break the call: Product cracks collapse faster than crude and Valero refining margin per barrel narrows instead.
  10. ▼ DVN Devon Energy — impact -67 · confidence low · horizon weeks · 1st order
    Devon Energy experiences lower operating cash flow because oil sales contribute substantially to production revenue.
    Chain: sanction relief lifts global oil supply → crude benchmarks decline → Devon oil sales revenue falls → operating cash flow contracts → variable dividend and buyback shrink
    What would break the call: Devon gas and NGL realizations rise enough to hold total revenue per barrel of equivalent flat.
  11. ▼ FRO Frontline — impact -66 · confidence low · horizon weeks · 2nd order
    Frontline loses the long haul ton mile premium created by sanctioned trade rerouting, softening tanker spot rates.
    Chain: sanctions end and Iranian trade normalizes → shadow fleet vessels return to compliant trading → effective tanker supply increases → long haul ton mile premium disappears → VLCC spot rates soften and Frontline earnings fall
    What would break the call: Higher global crude volumes lift total tanker demand and VLCC spot rates rise despite fleet reabsorption.
  12. ▲ LUV Southwest Airlines — impact +66 · confidence low · horizon weeks · 2nd order
    Southwest hedges less than peers, so falling fuel prices pass quickly through to earnings and fare flexibility.
    Chain: crude prices fall on Iranian supply return → jet fuel spot prices decline → Southwest limited hedging passes savings through quickly → fuel cost per available seat mile drops → operating margin improves
    What would break the call: Southwest adds hedges at current prices or domestic fare cuts absorb the fuel savings entirely.
  13. ▼ APA APA — impact -64 · confidence low · horizon weeks · 1st order
    APA earns less from oil production as increased Iranian exports pressure international crude pricing.
    Chain: Iranian exports return to global buyers → Brent linked pricing weakens → APA international realizations fall → operating cash flow declines → Suriname development funding tightens
    What would break the call: APA announces a major Suriname milestone that drives valuation independent of near term crude prices.
  14. ▲ ALK Alaska Air Group — impact +63 · confidence low · horizon weeks · 2nd order
    Alaska Air Group benefits from reduced jet fuel spending because energy represents a major variable operating expense.
    Chain: crude oversupply lowers refined product prices → jet fuel cost per gallon falls → Alaska Air fuel expense declines → unit cost per seat mile drops → operating margin expands
    What would break the call: West Coast refinery constraints keep regional jet fuel prices elevated despite lower global crude.
  15. ▼ DHT DHT Holdings — impact -60 · confidence low · horizon weeks · 2nd order
    Sanction relief returns Iranian barrels to mainstream fleets, shrinking the shadow fleet scarcity that lifted DHT rates.
    Chain: sanctions relief normalizes Iranian crude exports → shadow fleet tankers rejoin mainstream trading → compliant VLCC supply expands → spot charter rates decline → DHT time charter equivalent earnings fall
    What would break the call: Iranian volume growth lengthens voyage distances and total ton mile demand outpaces the added fleet supply.
  16. ▼ LBRT Liberty Energy — impact -60 · confidence low · horizon quarters · 3rd order
    Lower crude prices cut shale completion budgets which reduces frac fleet utilization and pressure pumping pricing.
    Chain: crude price decline cuts shale operator cash flow → completion budgets shrink in the Permian → frac fleet demand falls → Liberty utilization and pricing decline → service margin per fleet compresses
    What would break the call: Operators maintain activity to hold production targets and frac fleet utilization stays flat.
  17. ▼ HAL Halliburton — impact -57 · confidence medium · horizon quarters · 2nd order
    Weaker crude prices prompt producers to trim North American budgets, reducing Halliburton’s completion activity.
    Chain: lower crude prices cut producer cash flow → North American operators trim drilling budgets → completion and frac demand declines → Halliburton pricing and utilization fall → division operating margin compresses
    What would break the call: International and offshore contract awards grow enough to offset a North American activity decline.
  18. ▲ FDX FedEx — impact +57 · confidence low · horizon weeks · 2nd order
    FedEx captures lower transportation fuel costs which supports package delivery margins and pricing competitiveness.
    Chain: crude decline lowers diesel and jet fuel prices → FedEx ground and air fuel expense falls → fuel surcharge revenue also declines with index → net cost benefit supports operating margin
    What would break the call: Fuel surcharge revenue falls faster than fuel cost and FedEx net margin contribution turns negative.
  19. ▼ SLB SLB — impact -56 · confidence medium · horizon quarters · 2nd order
    Lower oil prices delay customer drilling projects, reducing SLB’s service orders and contract pricing power.
    Chain: crude prices fall on returning Iranian supply → operators defer drilling and project sanctions → SLB service order intake slows → pricing power on contracts weakens → revenue growth and margins decelerate
    What would break the call: Iranian field redevelopment awards contracts to international service firms and lifts SLB backlog instead.
  20. ▲ CCL Carnival — impact +56 · confidence medium · horizon weeks · 2nd order
    Cheaper bunker fuel reduces Carnival’s marine fuel expenditures, lowering voyage costs across its global fleet.
    Chain: crude decline lowers marine fuel prices → Carnival bunker cost per ton falls → voyage operating expense declines → net cruise cost excluding fuel improves → operating margin expands
    What would break the call: Carnival hedges or fuel surcharges are removed and the bunker saving is passed back to passengers.
  21. ▲ PSX Phillips 66 — impact +56 · confidence low · horizon quarters · 2nd order
    Phillips 66 processes cheaper feedstock while retail fuel demand rises with lower pump prices, supporting throughput and margin.
    Chain: returning Iranian barrels widen sour crude discounts → Phillips 66 feedstock cost declines → lower pump prices support gasoline demand → refinery throughput and utilization rise → refining segment margin improves
    What would break the call: Refined product cracks compress faster than crude falls and refining realized margin per barrel declines.
  22. ▲ MPC Marathon Petroleum — impact +55 · confidence low · horizon weeks · 2nd order
    Cheaper crude feedstock and stronger gasoline demand widen refining cracks across the largest US refining system.
    Chain: Iranian barrels return and crude prices fall → refinery feedstock cost declines → product prices lag the crude move → Marathon crack spread per barrel widens → refining segment earnings rise
    What would break the call: Gasoline cracks fall faster than crude and Marathon refining margin per barrel narrows.
  23. ▲ DOW Dow — impact +54 · confidence low · horizon weeks
    Dow obtains cheaper hydrocarbon feedstocks that reduce manufacturing costs for petrochemicals and plastics.
  24. ▲ RCL Royal Caribbean — impact +54 · confidence low · horizon quarters
