Three Strategies Ch. 4: Softness and Hardness Combined — Flexible Allocation, Rigid Risk Control
"Soft without hard is weakness; hard without soft breaks. Combined, their power is inexhaustible." — Huang Shigong
Military Context
The final section brings the work to synthesis: the highest strategy combines softness and hardness.
Pure softness produces hesitation and weakness; pure hardness produces rigidity and fracture. The superior commander yields to terrain and reassures troops while remaining iron in enforcing law and defending core lines.

The Three Strategies Trading Matrix
| Level | Military law | Trading and risk application |
|---|---|---|
| Upper | Softness overcomes hardness; asymmetric entry | Avoid the crash's edge; wait for exhaustion; ≥3:1 reward/risk |
| Middle | The weak controls the strong; tail protection | Protective hedging; leverage control; protect the root |
| Lower | Adaptation and regime shifts | Follow rate and inflation regimes; spot accumulation |
| Synthesis | Softness and hardness combined | Flexible allocation plus rigid risk execution |
Each Must Be Applied at the Right Layer
This is the book's most practical point and the easiest to invert.
Softness belongs to analysis: views on the market should be flexible, updating with evidence rather than defending prior positions. Hardness belongs to execution: once a rule is set, execution must be immovable.
Swapping them is catastrophic: rigid in analysis ("I know this will recover") and soft in execution ("wait a little, the stop can move down") — precisely the most common pattern of loss.
This restates the "stops move up, never down" rule from The Methods of the Sima Chapter 2 elsewhere in this library.
Why People Reliably Invert Them
The error is common enough to deserve an explanation.
The cause is that the felt difficulty of softness and hardness runs opposite to where they belong. Staying flexible in analysis means admitting you may be wrong, which is emotionally hard. Staying rigid in execution means accepting a certain loss, which is harder still.
So people slide toward the path of least resistance: holding firm in analysis (avoiding the admission of error) and leaving room in execution (avoiding the realisation of loss). Each choice separately dodges short-term pain, and together they form the most dangerous posture available.
The value of recognising this: when you notice yourself thinking "I'm confident, but let me wait a bit longer," you are already in the wrong combination.
Actionable Trading Blueprint
- Stay soft in analysis: hold no rigid view; let price action and data set your lean.
- Stay hard in execution: when a predefined condition triggers, act without re-arguing it.
- Check regularly whether you have inverted them: if you are inventing new reasons to hold a loser, softness and hardness have already swapped.
Relevance to a Retirement Portfolio
"Combining softness and hardness" has a precise translation for retirement portfolios: rigid structure, flexible tactics.
The rigid part: target stock/bond weights, rebalancing rules, withdrawal rate — fixed once set and not revised on market sentiment. The flexible part: shifting allocation gradually with age, adjusting withdrawals to actual spending needs, reassessing when life circumstances change.
Most retirees have this exactly backwards: the long-term structure changes constantly with market news (no rigidity), while an allocation that no longer suits their circumstances is defended stubbornly (no flexibility). Recognising which layer needs which is this chapter's greatest contribution.
