How should PMs manage duration timing positions through the cycle?

Duration timing requires balancing conviction signals with implementation discipline to avoid being systematically early or late through multiple rate regimes.

Hemlock's timing framework should include:

1. Signal Framework (Multi-factor conviction scoring)
- Growth indicators (ISM, employment, real retail sales)
- Inflation breakevens and trimmed-mean CPI
- Fed communications (dot plot, minutes, Chair speeches)
- Yield curve signals (2s10s, 3m10y inversion depth)
- Labor market tightness (JOLTS, wage growth)
- Credit spreads as leading indicator

2. Position Sizing by Conviction
- Tier 1 (>80% confidence): +1.5-2.0 years active duration
- Tier 2 (60-80%): +0.75-1.25 years
- Tier 3 (<60%): stay benchmark-neutral
- Prohibited: position exceeding risk budget even at max conviction

3. Staggered Implementation
- Build position over 2-4 weeks, not single day
- Scale in at technical levels (10Y resistance/support)
- Use futures for initial exposure (liquidity, easy unwind)
- Convert to cash bonds as conviction confirms

4. Exit/Trim Discipline
- Profit targets: trim 25-50% at +1-sigma move
- Stop-losses: halve position if thesis breaks (Fed surprise hawkish data)
- Time-based exits: if thesis hasn't played out in 6 months, reassess
- Regime-shift triggers: inflation surprise, labor reacceleration

5. Hedging Overlays
- Payer swaptions to cap downside on long-duration bets
- Risk reversals for asymmetric payoff profiles
- Curve trades (2s10s steepeners) instead of outright duration
- Butterfly strategies to isolate curvature views

Common timing errors Hemlock likely made:
- Anchoring on prior cycle playbook (each cycle is unique)
- Overweighting Fed dots at face value (dots often revise)
- Ignoring labor market strength (wages lag growth)
- Chasing the trade late (after much of the move already priced)

Historical cycle patterns:
- First cut often comes 6-9 months after last hike
- Initial duration rally historically +50-100bps; sustains 2-4 quarters
- Reversal risk high when cuts priced beyond fundamentals support

Performance measurement:
- Batting average on duration calls (% of correct directional calls)
- Slugging percentage (avg gain on winners / avg loss on losers)
- Consistent managers target 60%+ batting with 1.5+ slugging

Hemlock should document prior cycle post-mortems specifically identifying what signals they overweighted vs missed. Pattern recognition from past errors prevents repeating them. Combine this retrospective learning with the framework above, and active duration timing can add consistent alpha over full rate cycles.
