LXU relative to REX
Lsb Industries Inc is the relatively depressed leg. REX American Resources Corporation is the relatively extended leg.
Specific pair strategy
What is the play in LXU / REX?
This is a relative trade. The result depends on which security performs better, not on whether the whole market rises or falls.
Convergence condition active
Long LXU / short REX
Treat the two legs as one relative trade. The idea works when LXU outperforms REX, not simply when LXU rises or REX falls.
This is the relatively depressed leg. The case needs it to recover or at least hold up better than the other leg.
This is the relatively extended leg. The case needs it to lag or weaken relative to the long leg.
A favourable relative move means LXU rises more than REX, falls less than REX, or rises while REX falls. If REX outperforms LXU, the pair moves against the case.
The research trigger is active because the completed daily gap is narrowing while LXU improves relative to REX. For a fresh position, require the next completed daily update to continue that move toward normal.
Maintain the case only while LXU continues to gain on REX, relationship quality remains usable and the wider evidence does not reverse.
The case fails if the completed gap widens again while LXU weakens relative to REX, or if the publication moves into a relationship-break state.
Monitor whether the two evidence paths continue to close together alongside the spread.
Evidence now
- LXU Market Dynamics is improving.
- REX Market Dynamics is weakening.
What would invalidate it?
If either leg reverses its evidence path, the convergence case becomes one-sided and less dependable.
Possible setup paths
How the relative-value idea could be expressed
These are research structures, not recommendations or position-size instructions. The current course above determines whether any structure is ready to study now.
Long LXU / short REX
Treat both legs as one relative position. The setup looks for LXU to outperform REX; LXU can rise faster, fall less, or rise while REX falls. The pair loses ground when REX outperforms LXU.
When it becomes relevantThis is the clearest expression to study now because both the weekly evidence and completed daily timing agree. Look for LXU to keep gaining relative to REX while relationship quality and evidence alignment hold.Principal riskRequires a live review of both legs, borrow availability and cost, event dates, liquidity and the research normalisation.Study LXU alone if its own evidence confirms
This simpler expression focuses on recovery in LXU. It avoids short-borrow mechanics, but it no longer isolates relative value: the result is exposed to the broad market, the sector and LXU-specific news.
When it becomes relevantA stronger case needs improving LXU price structure and supporting evidence, not just a wide relationship gap.Principal riskCarries full single-security and broad-market direction risk.Study REX alone if its support continues to weaken
This expression focuses on weakness in REX. It may fit a leader-rollover case, but it also abandons the relative hedge and adds direct market direction, squeeze and company-event risk.
When it becomes relevantWeakening in REX must be visible in its own completed evidence; relative extension alone is not enough.Principal riskShort selling can involve unlimited loss, borrow fees, recalls and forced close-outs.Any practical expression needs an independent review of suitability, portfolio risk, liquidity, current news and earnings, borrow availability and cost, transaction costs and tax.
Relationship gap ยท technical name: standardised residual
How far apart are they compared with normal?
Zero is the pair's historical centre. The outer guides show increasingly unusual departures from it.
This is the relationship gap after allowing for the pair's usual co-movement. Zero is its historical centre; the distance is measured in standard deviations, so different pairs can be compared on the same scale.
The latest gap is 0.89 standard deviations from normal. LXU is the relatively depressed leg and REX is the relatively extended leg. That is unusual separation, not proof that either security is cheap or expensive.
A move toward zero means convergence. A move farther from zero means the separation is extending and raises the risk that the old relationship is changing.
Common-base price paths
Which security created the gap?
Both paths begin at 100 so their relative movement is visible without mixing different share prices.
Both securities are reset to 100 at the first date. This removes the distraction of different share prices and shows how their completed weekly price paths diverged. It is not a valuation chart.
Since the common starting point, LXU is +4.8% and REX is +123.3%. The chart shows which price path contributed to the separation; the fitted relationship measure is more precise than the raw visual distance.
For convergence, watch for LXU to catch up, REX to lose ground, or both. The relationship can close even if both securities rise or both fall.

Completed daily timing
Is the gap closing yet?
The daily relationship adds timing context inside the slower weekly case. It does not replace the weekly validity checks.
This applies the same relationship to completed daily bars. It is the timing layer inside the weekly case, not a separate trading signal.
Gap narrowing: The completed daily gap is narrowing. That supports the weekly convergence case, although it still needs to persist.
Further movement toward zero would strengthen confirmation; a turn away from zero would weaken it.

Relationship diagnostics
Why this pair is on the map
How closely completed weekly returns moved together across the measurement window.
How consistent the fitted relationship remained across earlier and later parts of the sample.
An observed mean-reversion clock, not a deadline or a forecast.
How often the residual crossed its historical centre; repeated crossings matter more than a single fit.
The latest residual's location inside its own completed history.
Stored price, volume and size context only. It does not include a live short locate or cost.
0 of 1 non-overlapping historical separations resolved after the relationship was fitted on earlier data.
Median time to return near the earlier fitted centre among the held-out cases that resolved.
The largest further move recorded after a measured held-out separation, before resolution or the observation window ended.
