Actionable insights — Weekend thread: cracks, gasoline, a Korea topping tell

1. "Jaws of death" — when refiner cracks rally away from a collapsing crude flat price, the gap closes toward cracks

1. Chart refiner crack spreads (refining margin) against crude flat price. A wide, widening divergence — cracks rallying while flat price collapses — is the "jaws of death" to fade.
2. Resolve which side leads: cracks lead crude input demand. Strong cracks mean refiners run flat out and pull more crude, so the flat price is the side that should converge upward, not the cracks that fall.
3. Require a physical catalyst to close the gap rather than assuming mean-reversion — identify the specific event (here, China lifting its product-export ban so SOE refiners run hard) and confirm it with behaviour, not just price.

• Cracks inflecting/rallying while flat price falls; refiners lifting physical cargos ahead of a policy change — the tell that the jaws close upward.

2. In a seasonal turn, watch the product that moves first — and read it at the PADD/arb level

1. Decide which product should lead the move on the calendar (gasoline into summer driving season) and watch its front spreads first, not crude.
2. Localize the tightness: read region-by-region (PADD1 product scarcity, PADD2 crude tightness) and the export arb (WTI vs Brent pricing exports in or out) to confirm "draws everywhere" rather than one-off noise.
3. Confirm with the cleanest expression — front-month product vs crude (RBOB vs WTI) "twitching" is the early signal the spread complex is turning.

• The seasonally-leading product's front spread inflecting; PADD-level scarcity; the export arb closing — before the headline crude price confirms.

3. Separate sentiment from positioning — abysmal sentiment is necessary but not sufficient

1. Gauge sentiment qualitatively (how bulls are talked about, how washed-out the mood is) — but treat it as only half the signal.
2. Demand that positioning confirm: check whether a sell-off actually removed length proportionate to the price (e.g. for crude at $75, did the "liquidation" take out the length you'd expect?). If price fell but length didn't, the flush is incomplete.
3. Wait for the hard positioning data (Commitment of Traders) before sizing on sentiment alone — note when it's delayed (holiday) and don't pre-commit. The combination of putrid sentiment + a not-yet-capitulated position is the "whiplash" setup, not the trigger.

• Washed-out sentiment paired with length that hasn't actually capitulated; the next CoT print confirming (or denying) the flush before you add.

4. New highs into weak divergence — fade a fresh high when breadth, volume and sponsorship don't confirm

1. When an index/ETF prints a new high, immediately check the internals: market breadth (how many constituents participate), trading volume, and sponsorship (real buying support).
2. If the new high comes on weak/diverging internals, treat it as a topping tell — "watch out" — not a breakout to chase.
3. Use it as a portfolio-wide risk read: a high-profile index topping on thin internals during a broadly painful tape signals "close to another skid lower."

• A fresh index high with deteriorating breadth/volume; opex- and quarter-end-driven positioning resets into "dreadful" liquidity that amplifies the next move both ways.
