Exxon: the downstream contribution is reverting to mid-cycle

This runs through the crack spread. Refining earnings are the spread between product and crude prices, and that spread mean-reverts far faster than either underlying price does. Crack spreads are public and have already normalised toward the five-year average, while the guided downstream contribution still reflects the peak period. The position: short on Exxon, entry locked at publication and the exit dated rather than open-ended. The target is stated in the call block above and the horizon with it. Sized to the catalyst rather than to conviction, with the invalidation written into the kill-switch card instead of left implicit. What breaks this is a supply outage that re-widens crack spreads. Those happen without warning and would make the normalisation argument wrong for several quarters.
