What the current structure is saying

Based on weekly closing prices
Setup lifecycle

Triggered

The lifecycle separates an interesting setup from price confirmation, an active thesis, maturity and invalidation.

Now

Possible bearish Wave 2 crest is the highest-ranked admissible primary count; cycle status is falling stack.

Next

A weekly close through 32.60, supported by an FLD cross and improving relative strength.

Wrong

The underlying directional structure fails beyond 38.15; a forming endpoint can extend before that happens.

Risk

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 hurst crest risk. Price is 12.7% above its 30-week trend. 3 of 7 available confirmation measures are constructive.

3 constructive · 0 neutral · 4 weak

What would confirm the risk

Evidence of deterioration

  • A weekly close below 32.60, the nearest confirmed swing low.
  • Cycle pressure rolling from cresting into falling.
  • Relative strength and market activity losing neutral.

Price, trend and the active swing

The chart uses a 6.5% closing-price reversal threshold. Filled markers are confirmed pivots; the outlined final marker is still forming.

Primary admissible count

Possible bearish Wave 2 crest

38% evidence weight

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.

Cycle pressure

Above zero is positive pressure; direction matters more than the absolute number.

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.

This is a count of rules-based evidence, not a recommendation.

Market activity

Whether participation is supporting the move.

Relative strength

Performance against the market benchmark.

30-week momentum

The pace of the medium-term price move.

Market dynamics

A separate scale prevents this lower-range measure being hidden by relative strength.

Risk and participation

How much movement sits behind the pattern?

Wave structure is easier to judge when drawdown, volatility and participation are visible beside it.

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.

Sector breadth

23% constructive

5 of 22 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.
Event collision

No near collision identified

No stored event or positioning warning currently conflicts with the count.

Event and positioning context tests whether a scheduled catalyst or the options-implied move could overwhelm the technical structure.

How the count is built

Rules, references and limitations

  • Swing points use weekly closes and a 6.5% 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.
