What the screen said this week
The screen classified the current environment as mid-cycle, based on the macro vintage as of 2026-08-27. The reasoning cited industrial production (INDPRO) growing at +1.1% year over year, which sits inside the 0.0% to 4.0% band the rule set treats as steady expansion, alongside a positive yield curve reading of +0.47. In plain terms, the rule set is reading the economy as expanding at a moderate pace rather than accelerating or contracting.
Technology (XLK) topped the composite at 82.2, followed by Communications (XLC) at 74.1. Both carry a Buy signal under this rule set, and both are lifted primarily by a maximum cycle-fit score of 100.0, with Technology also showing the strongest relative strength (RS) in the table at 75.4. Relative strength here measures how a sector is performing against the broad market. Every other sector landed in Hold territory, clustered between roughly 40 and 52 on the composite.
No sector triggered a Watch flag this week, which would require cycle fit at or above 80 while relative strength stays under 45. On the low end, Consumer Staples (XLP) at 35.9 and Utilities (XLU) at 30.5 both carry Avoid signals, weighed down by weak relative strength readings of 21.7 and 11.2 respectively.
Things worth noticing
There is a visible split between cycle fit and recent price action. The two Buy sectors, Technology and Communications, both show negative three-month relative returns (rs3m of -4.64% and -4.04%), while several Hold-rated sectors like Healthcare (+13.05%), Financials (+11.07%), and Energy (+10.19%) posted the strongest three-month numbers. In other words, the sectors the cycle rule favors are not the ones that have led on price lately.
The Communications seasonality score of 73.1 is explicitly flagged as a thin sample. Seasonality here refers to historical calendar-based tendencies, and a thin sample means fewer observations underpin that number, so it deserves more caution than the headline value suggests.
It is also worth noting the Buy-signal track record in the stats box: since May 2011, Buy calls beat SPY only 50% of the time and were positive 64% of the time, with an excess return near zero. The strategy also did not beat SPY net of trading cost over the backtest window.
Methodology reminder
The composite is the weighted sum of Seasonality (25%), Cycle Fit (40%), and Relative Strength (35%). Lookahead bias in the backtest is controlled using FRED ALFRED point-in-time vintages, so the macro inputs reflect what was actually known at each date. The backtest figures are a property of this specific rule set, not a forecast of future results.
