What the current structure is saying
Setup lifecycle
Watching
The lifecycle separates an interesting setup from price confirmation, an active thesis, maturity and invalidation.
A weekly close through 37.38, supported by an FLD cross and improving relative strength.
The underlying directional structure fails beyond 28.93; a forming endpoint can extend before that happens.
The active endpoint can move until its reversal is confirmed; earnings, gaps and volatility can jump through technical levels.

This is a pre-emptive vulnerability checklist, not a probability of decline. It rises when mature wave structure, overextension, cycle rollover, count instability and event risk cluster before price breaks down.
Current read
The closing-price swing map is classified as possible wave 2 trough. Price is 6.6% below its 30-week trend. 1 of 7 available confirmation measures are constructive.

Evidence to look for next
- A weekly close through 37.38, the nearest confirmed swing high.
- Cycle pressure and the 20/40-week rhythms continuing to rise together.
- Relative strength and market activity remaining above neutral.

Possible Wave 2 trough
Counts must pass hard Elliott geometry rules. Fibonacci relationships, alternation and cycle evidence rank admissible interpretations; evidence weights compare scenarios and are not forecast probabilities.

Cycle timing
Are the main rhythms moving together?
Nominal cycles are starting bands, not fixed clocks. Each period adapts to the strongest nearby repeat in detrended weekly prices; projected turns are future intervals and require price confirmation.

Does price behaviour support the wave count?
Each measure answers a different question. Agreement across several measures is more useful than one strong reading in isolation.

Market, peer and event context
Is the structure isolated—or supported by its environment?
Peer breadth tests whether the sector is moving with this security. Event and options context tests whether a catalyst could overwhelm otherwise valid technical structure.
47% constructive
8 of 17 analysed peers have a bullish rule-valid primary count.
41% have improving cycle stacks Breadth shows whether peers share the structure. Cohort outcomes use non-overlapping, point-in-time trend and momentum states from the same sector and report benchmark excess return when matching benchmark bars exist; they are context, not a backtest of the Elliott count.Elevated invalidation risk

Rules, references and limitations
- Swing points use weekly closes and a 9.2% adaptive reversal threshold.
- The final swing is provisional until the reversal threshold is met.
- Candidate counts must pass the Wave 2 origin, Wave 3 progression/length and Wave 4 overlap rules when those waves are present.
- Fibonacci proportions and alternation rank valid candidates but never rescue a hard-rule failure.
- Primary and alternate evidence weights compare admissible counts; they are not probabilities.
- Nominal Hurst periods adapt to observed weekly rhythm. Future windows include measured timing uncertainty and require FLD or price confirmation.
