Executive reading

What the weekly evidence says now

Direction is rules-based, not predicted
Positive across all horizons

All four measured horizons are positive

The 13, 26, 39 and 52-week readings point in the same direction, giving the current regime unusually broad horizon agreement.

  • The current 52-week regime has lasted 8 completed weeks.
  • The latest close is 27.2% above the decision boundary.
  • The primary signal changed direction 9 times during the last 52 completed weeks.

Weekly close and the moving 52-week boundary

When the close is above the boundary the primary state is positive; below it, negative. Regime shading records what was known at each completed week.

52-week momentum through time

The zero line is the regime boundary. Distance from zero shows how much of the trailing return would have to unwind before direction changes.

Horizon breadth

Agreement through time

Four means all tracked horizons agree with the current 52-week direction; lower readings reveal internal tension.

Point-in-time evidence

What followed similar states in this market?

Descriptive history, not a forecast

Each observation uses only the direction and horizon agreement available at that completed week. Samples are spaced by the measurement horizon to reduce repeated overlap. Fewer than five observations are shown but marked as too thin for a dependable inference.

Risk-equivalent view

How noisy is this trend?

Direction and sizing are separate questions
Annualised weekly volatility+35.7%

The realised variability of weekly returns over the recent 26-week window.

Volatility stability0.8387×

Recent 13-week volatility relative to the broader 52-week estimate. Above 1 means risk has accelerated.

Illustrative risk scale0.2802×

A capped 10% annual-risk normalization. It is a comparison tool, not a position recommendation.

Boundary sensitivityNormal

The current boundary margin is not unusually small relative to recent weekly volatility.

Move inside current regime+10.6%

Close-to-close movement since the present 52-week direction first became active.

Deepest pullback inside regime-0.4%

The largest counter-trend move observed without the primary state changing direction.

Risk path

Annualised weekly volatility

Rising volatility can make an otherwise persistent direction harder to hold and increases the chance of crossing a boundary abruptly.

Independent context

Sharemaestro evidence around the trend

Context never changes the core direction

These are separate Sharemaestro readings from the same latest completed week. They can explain participation, value or relative pressure, but none is allowed to overwrite the transparent 52-week signal.

Exactly what this report measures

Primary state

Positive when the latest adjusted weekly close is above the adjusted close exactly 52 completed observations earlier; negative when below; neutral only when equal. Discontinuous histories are excluded. This is a stock-and-ETF research adaptation, not a replication of a diversified futures strategy.

Diagnostic horizons

The same calculation is repeated at 13, 26 and 39 weeks. Their agreement measures coherence. They cannot veto or replace the 52-week state.

Historical evidence

Forward returns start after each historical decision week. Matching uses the direction and number of aligned horizons known then, with spaced samples and visible counts.

Known failure modes

Trend persistence can reverse, suffer repeated whipsaws, or cross its boundary by a gap. Transaction costs, tax, borrow availability and implementation slippage are not modelled.

Independent market research for education. Not investment advice, a recommendation, a forecast or an execution instruction. Past states and outcomes do not establish what will happen next.
