SIGNAL OVERVIEW
The simplest signal in a crude PM playbook is that recent price carries. A 20-day uptrend tends to extend. A 20-day downtrend tends to persist. The signal reads the 20-day log-return of WTI ratio-adjusted continuous, z-scored against its 252-day rolling distribution, then tanh-bounded. Positive composite means recent momentum up. Negative composite means recent momentum down.
The thirty-seven-year state-conditional edges are monotonic. The uptrend state (44.0 percent of the sample) delivers a plus 0.58 percent fwd 60-day edge above the plus 2.53 percent baseline. The downtrend state (40.8 percent) delivers a minus 0.58pp edge. Daily IC plus 0.021 at p=0.046 clears conventional significance on dense sampling. The signal catches the big trending crude moves (2008 GFC minus 68 percent in state downtrend, 1994 Kuwait tension plus 37 percent in state uptrend).

What the chart is showing. The dark line in the top panel is the 20-day crude momentum composite on a tanh-bounded plus-or-minus one scale. Positive means recent price momentum up (bullish uptrend). Negative means recent price momentum down (bearish downtrend). The bronze line in the middle panel is WTI ratio-adjusted continuous. The bottom panel tracks the 252-day rolling IC.

TODAY’S PLAYBOOK READING
STATE
Moderate Pos
STATE AND HISTORY
Composite +0.217 (Moderate POS, 1 sessions). The 20-day log-return of crude is roughly a quarter standard deviation above its 252-day rolling average. State uptrend has historically delivered plus 0.58pp edge above the plus 2.53 percent baseline.
THE MOMENTUM-CARRIES MECHANIC
Markets trend because position-adders follow price. When crude runs up 20 days in a row, speculators who missed the entry chase, physical commercials pull inventory forward, and refiners build stocks against expected product demand. The 37-year monotonic edge pattern confirms it.
HOW TO POSITION
Daily IC plus 0.021 at p=0.046 clears conventional significance on dense sampling. Non-overlap 63-day IC plus 0.104 at p=0.21 is marginal. The signal is a state-conditional backdrop. Read alongside the crude macro and positioning signals for a stack covering macro cost, positioning, demand, and price-technical channels.
WHAT THE CHART SHOWS
The composite tag at the right edge of the top panel is sitting at +0.217, just past the plus 0.2 Moderate POS threshold. The bronze WTI line in the middle panel has traced a mild up-slope over the recent 20-session window.

- Raw rolling z-score -0.29 The 20-day log-return of crude is roughly 0.25 standard deviations above its 252-day rolling average.
- Phase run 1 sessions Current Moderate POS regime entered October 23, 2026 after drifting out of Neutral.
THE TAKEAWAY
What this means for you today
WHAT THE MOMENTUM READ IS TELLING YOU
The composite reading of +0.217 sits in the Moderate POS band, 1 sessions into the current regime. The raw z is -0.29. The recent 20-day price action is mildly bullish. Not extreme uptrend but past the plus 0.2 state threshold. The state-conditional forward sixty-day expectation is plus 3.12 percent, a plus 0.58pp edge above the plus 2.53 percent baseline.
THE CRUDE STACK
This signal is the price-technical leg of the crude stack. The the US 10-year TIPS yield real-rate overlay reads macro cost of inventory. The CFTC heating-oil positioning reads downstream demand. The macro demand composite reads the four-channel macro backdrop. This signal reads recent price itself. The first three are external drivers; this signal is what the market has already done.
WHAT WOULD CHANGE THIS READING
Two triggers. First, the composite crosses above plus 0.6 (Extreme POS, strong uptrend). That requires the 20-day log-return to accelerate to roughly two standard deviations above the rolling average. Second, the composite drops below minus 0.2 (Moderate NEG, downtrend). That would join the other crude signals in a stacked bearish read.
THE REGIME MAP
The three regime states, forward returns and sample share
Behavior across the 20-day momentum composite (NYMEX WTI crude benchmark, 1989 through present). WTI crude forward 60-day baseline is plus 2.53 percent across 9,208 live-signal days. CLEAN MONOTONIC three-regime edge.

The historical pattern of crude momentum across trending regimes
The signal across 37 years of 20-day crude momentum
What this measures
Recent price momentum in crude extends through three force-aligned channels. Speculators chase the entry. Physical commercials pull inventory forward. Refiners build stocks against expected product demand. All three push the same way, and the 20-day log-return of WTI captures that combined pressure as a single reading.
Why it matters
Why 20-day momentum predicts forward returns in crude
Markets trend because position-adders follow price. When crude runs up 20 days in a row, three forces push the same way. Speculators who missed the entry chase in. Physical commercials pull inventory forward to lock in the higher margin. Refiners build stocks against expected product demand. All three force the price higher. The 37-year monotonic edge confirms the mechanic. Uptrend state delivers plus 0.58pp forward 60-day edge. Downtrend state delivers minus 0.58pp edge.
Why this is the price-technical complement to the macro signals
The crude stack reads four structurally-independent channels. The the US 10-year TIPS yield real-rate overlay reads macro cost of inventory. The CFTC heating-oil positioning reads downstream speculator positioning on distillate. The macro demand composite reads the four-channel macro backdrop. This signal reads recent price itself. The first three are external drivers. This signal is what the market has ALREADY DONE.
How to use this signal today
The composite +0.217 reading is in the Moderate POS band and the phase has been running 1 sessions. The state-conditional forward sixty-day expectation is plus 3.12 percent, a plus 0.58pp edge above the plus 2.53 percent baseline. Watch for the next 20-day log-return crossover.
