Specific pair strategy

What is the play in EXC / FTS?

This is a relative trade. The result depends on which security performs better, not on whether the whole market rises or falls.

Watchlist pair - not triggered

Possible future structure: long EXC / short FTS

The proposed pair would look for EXC to outperform FTS, but the current evidence does not yet justify treating the gap as a convergence trade.

Potential long leg Long EXC Exelon Corporation

This is the relatively depressed leg. The case needs it to recover or at least hold up better than the other leg.

Potential short leg Short FTS Fortis Inc

This is the relatively extended leg. The case needs it to lag or weaken relative to the long leg.

How the pair can make money

A favourable relative move means EXC rises more than FTS, falls less than FTS, or rises while FTS falls. If FTS outperforms EXC, the pair moves against the case.

What triggers it

Wait for a completed daily turn toward normal and fresh evidence that EXC is improving relative to FTS. The size of the gap alone is not the trigger.

What keeps it valid

If the daily gap keeps widening, leave the pair alone rather than averaging into the separation.

What cancels the case

Do not use the pair if the completed gap keeps widening, EXC continues to weaken relative to FTS, or the relationship moves into a break state.

What would confirm the research case?

Monitor whether the two evidence paths continue to close together alongside the spread.

Evidence now

  • EXC Market Dynamics is improving.
  • FTS 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.

Two-leg convergence structure

Long EXC / short FTS

Treat both legs as one relative position. The setup looks for EXC to outperform FTS; EXC can rise faster, fall less, or rise while FTS falls. The pair loses ground when FTS outperforms EXC.

When it becomes relevantThis is a structure to study only after the current course changes from โ€œWait for the daily turnโ€ to confirmed convergence. The clearest next checkpoint is a sustained turn from a stable or extending daily gap to a narrowing one.Principal riskRequires a live review of both legs, borrow availability and cost, event dates, liquidity and the research normalisation.
Depressed-leg recovery study

Study EXC alone if its own evidence confirms

This simpler expression focuses on recovery in EXC. It avoids short-borrow mechanics, but it no longer isolates relative value: the result is exposed to the broad market, the sector and EXC-specific news.

When it becomes relevantA stronger case needs improving EXC price structure and supporting evidence, not just a wide relationship gap.Principal riskCarries full single-security and broad-market direction risk.
Extended-leg rollover study

Study FTS alone if its support continues to weaken

This expression focuses on weakness in FTS. 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 FTS 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.

What this chart is

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.

What it says now

The latest gap is 1.34 standard deviations from normal. EXC is the relatively depressed leg and FTS is the relatively extended leg. That is unusual separation, not proof that either security is cheap or expensive.

What matters next

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.

Historical standardised relationship residualThe line shows how far the relationship sat above or below its fitted centre over completed weekly observations.
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.

What this chart is

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.

What it says now

Since the common starting point, FTS is +61.5% and EXC is +27.5%. The chart shows which price path contributed to the separation; the fitted relationship measure is more precise than the raw visual distance.

What matters next

For convergence, watch for EXC to catch up, FTS 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.

What this chart is

This applies the same relationship to completed daily bars. It is the timing layer inside the weekly case, not a separate trading signal.

What it says now

Gap extending: The completed daily gap is still widening. The weekly separation may be interesting, but timing has not confirmed a turn.

What matters next

The first useful change would be for the daily line to stop extending and begin moving back toward zero.

Why this pair is on the map

Return co-movement0.66

How closely completed weekly returns moved together across the measurement window.

Residual stability63/100

How consistent the fitted relationship remained across earlier and later parts of the sample.

Typical decay7.5 weeks

An observed mean-reversion clock, not a deadline or a forecast.

Mean crossings15

How often the residual crossed its historical centre; repeated crossings matter more than a single fit.

Spread percentile96th

The latest residual's location inside its own completed history.

Tradability context84/100

Stored price, volume and size context only. It does not include a live short locate or cost.

Held-out resolution 0%

0 of 3 non-overlapping historical separations resolved after the relationship was fitted on earlier data.

Typical resolutionNot observed

Median time to return near the earlier fitted centre among the held-out cases that resolved.

Worst extension+1.07ฯƒ

The largest further move recorded after a measured held-out separation, before resolution or the observation window ended.

Measure guide

Weekly separation

How far the latest completed weekly relationship sits from its own historical centre.

A larger reading means the two securities are unusually far apart relative to this relationship's completed history. It identifies a dislocation; it does not, by itself, predict convergence.

Measure guide

Daily timing

The direction of the gap across the latest completed daily sessions.

Narrowing means the daily gap has begun to close, extending means it has widened, and stable means the change is not yet material. The weekly relationship remains the primary research clock.

Measure guide

Relationship quality

A public summary of how dependable the completed historical relationship has been.

It brings together repeatability, stability and later-sample behaviour. Higher is stronger, but no score guarantees that a historical relationship will continue.

Measure guide

Evidence alignment

Whether the wider stored evidence supports the depressed leg relative to the extended leg.

The comparison uses published price structure and supporting research for both securities. Higher alignment means more of that evidence points in the same relative direction; construction weights are not disclosed.

Measure guide

Stability

How consistently the relationship held across earlier and later completed observations.

Higher stability means the relationship changed less across the sample. It is a durability check, not a forecast or a guarantee of mean reversion.

Measure guide

Break risk

The risk that the earlier relationship is no longer a dependable reference point.

Lower is better. A high reading warns that the separation may reflect new information or a structural change rather than a temporary gap.

Measure guide

Research normalisation

A common scale used to compare the two historical price paths.

It describes the fitted relationship for research. It is not a position size, hedge instruction or risk target, and it excludes live borrow, fees, slippage and portfolio constraints.

Measure guide

Held-out resolution

How often earlier measured separations later moved back near their fitted centre.

Each historical check is fitted only on information that came before it. The result is descriptive evidence from this relationship's history, not an expected return or future probability.
