Ukraine is hitting refineries, not wellheads: Russian crude gets cheaper while diesel margins balloon for refiners outside Russia

By destroying Russian refineries, Ukraine pushes crude onto the market and takes diesel off it: that drags down the price of crude and blows out margins for refiners outside Russia.

Why this company: The largest refining capacity in the US. Its Gulf Coast refineries ship fuel to Europe and Latin America whenever diesel there gets more expensive. No upstream risk, pure exposure to the refining margin.

MPC since this thesis was published: +14.0% · whole basket +12.8%

Where these numbers come from

The reference price is recorded on the thesis publication date and never changed afterwards. The current price is refreshed several times a day. Returns are in the listing currency and exclude dividends, so for dividend payers the real total return was somewhat higher.

This is not a recommendation to buy or sell. A company enters a basket as a beneficiary of the mechanism described in the thesis, and the full argument is on each thesis page.
