What the screen said this week
The screen classified the current environment as mid-cycle. That call comes from industrial production (INDPRO) growing 1.7% year over year, which sits inside the rule set's 0.0% to 4.0% band, combined with a positively sloped yield curve at +0.38. In this rule set's language, that combination reads as steady expansion rather than early recovery or late-cycle stress.
Technology (XLK) topped the composite at 82.8, the only sector carrying a Buy signal this week. It scored well across all three inputs: strong seasonality (85.7), maximum cycle fit (100.0), and the highest relative strength in the group (61.2, with three-month relative strength of +19.60%). Communications (XLC) came in second at 73.5 and was flagged Watch, meaning the cycle input favors it (cycle fit 100.0) but relative strength has not confirmed (37.1, with three-month RS of -13.37%). Everything else landed in Hold territory. No sector triggered an Avoid signal this week, though Healthcare (XLV) sat lowest at 42.2, just above the 40 threshold.
Things worth noticing
The gap between XLK and the rest of the field is worth sitting with. Both XLK and XLC show maximum cycle fit and strong seasonality, yet their composites differ by about 9 points. The difference is relative strength: XLK's price momentum has confirmed while XLC's has not. That is precisely the split the Watch flag is designed to surface.
Several sectors carry high seasonality scores but middling composites. Real Estate (XLRE) shows the strongest seasonality reading (89.6) yet ranks sixth, dragged down by weak relative strength (29.6) and a middling cycle fit (50.0). This illustrates how the weighting scheme, which leans most on cycle fit, can hold a seasonally favored sector back.
One caution flag: XLC's seasonality is marked "thin sample." Communications as a standalone sector has a shorter clean history, so that 82.0 seasonality figure rests on fewer observations than the others and deserves lighter weight when reading the ranking.
Methodology reminder
The composite is a 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 each historical week sees only the macro data that was actually available then. The backtest figures, including the +636.33% result, are a property of this specific rule set over the window since May 2011, not a forecast of anything.
