Growth-Trend Timing — Unemployment (GTT-UE)
Developed by Philosophical Economics · Macro + Trend · Low Risk
Growth-Trend Timing using unemployment data is the companion strategy to the INDPRO variant, also developed by the Philosophical Economics blog. GTT-UE replaces the industrial production signal with the US unemployment rate as its macro regime indicator, applying the same fundamental logic — position in equities during economic expansion, shift to bonds during contraction — through a different lens of economic measurement.
The unemployment rate offers distinct advantages and disadvantages relative to industrial production as a macro timing indicator. Its primary advantage is intuitive clarity: rising unemployment is the single most visible and politically salient indicator of economic recession, and its relationship with equity market performance is among the most well-documented in financial economics. When unemployment is rising, consumer spending contracts, corporate earnings decline, loan defaults increase, and equity valuations compress — a reinforcing cycle that produces the deep drawdowns tactical strategies aim to avoid.
The signal compares the current unemployment rate against its twelve-month moving average. When unemployment is below its average — indicating improving or stable labor market conditions — the strategy holds US equities. When unemployment rises above its average — indicating deteriorating conditions — the portfolio shifts to intermediate bonds. This smoothed comparison filters out the normal monthly fluctuation in employment data while remaining responsive to the sustained increases that characterize genuine recessions.
Like its INDPRO counterpart, GTT-UE produces a strategy with very few transitions, very low turnover, and a strong correlation with economic fundamentals rather than market sentiment. The unemployment signal is a lagging indicator — it typically turns negative after the economy has already weakened and equity markets have already begun declining. This means the strategy will absorb some of the initial drawdown before the defensive signal triggers. However, the lag also provides a benefit: the signal does not generate false alarms from temporary market corrections or sentiment-driven selloffs that do not involve actual economic deterioration.
How It Works
The Unemployment Signal
Each month, following the Bureau of Labor Statistics' release of the unemployment rate, the strategy compares the current rate against its trailing twelve-month moving average. When the unemployment rate is at or below its average, labor market conditions are considered stable or improving, and the strategy holds equities. When the rate rises above its average, conditions are deteriorating, and the strategy shifts to bonds.
The twelve-month moving average comparison serves two purposes. It normalizes for the gradual structural changes in unemployment that occur over economic cycles — the "natural rate" of unemployment varies across decades, and a fixed threshold would lose relevance over time. And it smooths out the monthly noise that makes raw unemployment data difficult to interpret, requiring a sustained trend rather than a single-month spike to trigger the signal.
Binary Allocation
When the unemployment signal is favorable (rate at or below its moving average), the portfolio holds 100% US equities (SPY). When the signal turns negative (rate above its moving average), the portfolio shifts entirely to intermediate bonds (IEF). The binary positioning provides maximum equity exposure during expansions and maximum protection during contractions.
The simplicity mirrors the INDPRO variant — a single publicly available data point, released on a known schedule, driving a single binary allocation decision. The strategy requires no proprietary calculations, no optimization, and no multi-factor analysis. This transparency makes it among the most accessible tactical strategies for investors who want a systematic approach to recession avoidance without the complexity of momentum-based systems.
Lagging but Reliable Signal
The unemployment rate is widely recognized as a lagging economic indicator. It typically begins rising after the economy has already entered recession, often several months after equity markets have started declining. This means GTT-UE will absorb the initial phase of bear market drawdowns before its signal confirms the regime change.
However, the lagging nature provides a critical benefit: the signal almost never generates false alarms. Because unemployment only rises above its moving average during genuine economic downturns, the strategy avoids the whipsaw problem that plagues faster, price-based signals. When the unemployment trigger fires, it almost always represents a real recession that justifies the defensive shift — and the subsequent bond allocation typically persists until the recession ends and unemployment begins a sustained decline, avoiding premature re-entry during bear market rallies.
The comparison between GTT-UE and GTT-INDPRO illustrates a fundamental trade-off in macro timing: industrial production turns earlier (it is a coincident indicator) while unemployment turns later (it is a lagging indicator). The INDPRO variant exits equities earlier but also generates slightly more false signals. The unemployment variant exits later but with higher conviction. Neither is objectively superior — they serve different preferences along the speed-reliability trade-off continuum.
