Target Audience
Ideal Reader
- Macro/global macro investors who want a framework for reflexive, feedback-driven markets
- Traders who learn best from a real-time decision diary and process-focused updates
- Investors studying bubbles, credit cycles, and regime shifts beyond equilibrium models
- Portfolio managers who need to manage narratives, liquidity, and policy reactions as causal forces
Investor Fit
| Strategy | Macro/Global · Behavioral Finance · Portfolio Management · Global Macro |
| Time Horizon | Short-term (< 1 year) · Medium-term (1–5 years) · Long-term (5+ years) |
| Asset Focus | Macro/FX · Currencies · Rates · Equities |
| Math Level | Conceptual |
| Prerequisites | Comfort thinking in feedback loops (not linear cause -> effect) · Basic macro literacy (rates, FX, credit conditions) · Willingness to operate without neat models and to update views fast |
Key Learnings
- 1Markets do not just reflect fundamentals; in some regimes they help create them (reflexivity)
- 2Prices can change behavior, funding, regulation, and corporate actions - then those changes feed back into prices
- 3Under uncertainty, the key skill is not being right but adapting quickly when you're wrong (fallibility)
- 4Boom-bust cycles are often driven by positive feedback loops that eventually break
- 5Narratives can be causal forces (they move capital, credit, and policy), not just explanations
- 6The best risk control is avoiding one-way, fragile exposures when feedback turns against you

Reflexivity in the Stock Market
Takeaway
Equity prices can influence corporate behavior and perceived fundamentals, not just respond to them.
Reflexivity in the Currency Market
Takeaway
FX can behave reflexively via flows, policy, and confidence; equilibrium assumptions can fail.
The Credit and Regulatory Cycle
Takeaway
Credit expansion and regulatory stance can amplify booms and accelerate busts.
Trading/decision diary (Aug 1985 through Nov 1986 sections)
Takeaway
Shows how a macro investor updates views in real time - useful as a process model, not as a copy-trade blueprint.
Mental Models
- —Reflexivity loop: perception <-> action <-> reality <-> perception
- —Positive vs negative feedback (self-reinforcing vs self-correcting)
- —Underlying trend + prevailing bias (bubble building blocks)
- —Fallibility as a feature: iterate, test, revise
- —Regime shifts: relationships change when feedback loops dominate
Key Terms
No glossary terms documented for this book.
Limitations & Caveats
Keep in mind
- •Not a rules-based system; easy to agree with and still fail to operationalize
- •Reflexivity can be hard to falsify; sloppy users can turn it into unfalsifiable storytelling
- •Macro implementation involves carry, timing, and liquidity - none of which are forgiving
