Applying General Jomini's principle of the Decisive Point (决胜点) to concentrating capital at key market breakouts.

Summary of the Art of War — Chapter 1: The Decisive Point (决胜点)

"The fundamental principle of all military operations is to throw the mass of your forces upon the decisive point of the battlefield." — General Antoine-Henri Jomini (约米尼)

The Military Context

General Antoine-Henri Jomini (1779–1869) was Napoleon's strategic staff officer and author of Summary of the Art of War (《战争艺术》), the foundational textbook taught at West Point and European military academies.

Jomini codified warfare into scientific principles. His core law was The Decisive Point: victory is achieved by concentrating the maximum mass of your army at the single strategic point where the enemy is most vulnerable, rather than dispersing troops evenly across a wide front.

The Wall Street Translation

In portfolio management, dispersing capital equally across 50 random stocks dilutes your returns and guarantees index-like (or worse) performance—a trap Peter Lynch called "diworsification."

1. Identify the Decisive Market Point (识别市场决胜点)

A "Decisive Point" in trading is a technical or fundamental bottleneck where buyers and sellers clash with high volume: - Major Resistance Breakouts: When a stock consolidates in a tight base for 12 weeks and breaks out above resistance on 200% average volume. - Earnings Surprises: When a high-quality company beats earnings expectations by 30% and raises forward guidance.

2. Massing Capital into Conviction Positions (集中兵力于高确信度)

When a high-probability Decisive Point presents itself: - Concentrate Firepower: Allocate 5–10% of portfolio equity into top-tier conviction setups rather than tiny 0.5% positions. - Top-Quintile Focus: Rank stocks by relative strength and factor momentum. Put capital into the top 10% strongest performers.

3. Avoiding Dilution Across Minor Fronts (切忌兵力分散)

Do not waste capital on mediocre setups just to "stay busy." If there are no clear Decisive Points in the market, hold cash reserves.

Actionable Trading Rules

  1. Focus on High-Conviction Setups: Limit active trading portfolio to 8–12 highly conviction positions rather than 40+ micro-positions.
  2. Weight Positions by Conviction: Scale position sizing up for setups that meet 100% of your trading criteria (e.g. 8–10% allocation) vs secondary setups (2–3%).
  3. Execute at the Decisive Moment: Enter at the precise moment of price/volume breakout, never chasing extended moves 15% past the entry pivot.
