The Art of War for Trading — Chapter 4: Dispositions & Invincibility First

"The good fighters of old first put themselves beyond the possibility of defeat, and then waited for an opportunity of defeating the enemy." — Sun Tzu

Strategic & Financial Context

Dispositions defines the relationship between defense and victory. Sun Tzu establishes his most fundamental law: Make yourself invincible first, then wait for the enemy's vulnerability. You control your defenses; the market dictates opportunities.

In trading, you cannot force the market to rise ("victory depends on the enemy"), but you have 100% control over position sizing, risk limits, and leverage ("invincibility rests with yourself").

Wall Street Application

1. Building an Invincible Risk Defense

• Hard Stop-Loss Limits: Cap single-trade risk at 1% of portfolio equity to eliminate blow-up risk.
• Reject Toxic Leverage: High leverage destroys invincibility, subjecting account balances to margin calls during temporary noise.
• Volatility Position Sizing: Adjust size based on market ATR: lower size when volatility expands.

2. "Victorious Warriors Win First"

| Regime | Defeated Traders | Victorious Traders | |---|---|---| | Execution | Enter first, then hope and pray for profit | Lock in downside protection before taking risk | | Emotion | Panicked by daily price fluctuations | Calmly monitoring execution against pre-built plans |

Trading Execution Rules

1. Defense First: First question before entering a trade: "What is my maximum loss?"
2. Execute Mechanical Stops: Respect predefined stops without rationalization.
3. Maintain Cash Reserves: Hold cash buffers to survive Black Swan panics.

Relation to Retirement Portfolios

Dispositions serves as the core mandate for retirement capital. The priority is invincibility—eliminating tail risks that cause permanent capital impairment (e.g., maintaining short-term Treasuries and cash reserves). Secure your base before seeking upside.
