Sun Tzu Ch. 3: Attack by Stratagem
"To win a hundred victories in a hundred battles is not the highest excellence; to subdue the enemy without fighting is the highest excellence." — Sun Tzu
Military Context
This chapter contains the book's most famous and most often misquoted claim: the highest form of war is complete victory — winning with your army and resources intact.
Note the precise wording: a hundred victories is "not the highest excellence." Winning a hundred battles is not mastery — because each victory consumed troops, time, and national strength. The true master makes the opponent yield through deterrence, position, and patience, without engaging.
Sun Tzu then gives an explicit ranking:
"The highest form of warfare is to attack strategy itself; next, to attack alliances; next, to attack armies; the lowest is to attack walled cities."
| Rank | Method | Cost |
|---|---|---|
| Highest | Attack the enemy's strategy | Lowest |
| Second | Break their alliances | Low |
| Third | Defeat their army | High |
| Lowest | Assault fortified cities | Highest, and often self-defeating |
Siege is explicitly the worst option, and Sun Tzu explains why: preparing engines takes months, and a commander driven by anger sends men swarming the walls, "killing a third of his soldiers while the city remains untaken — this is the calamity of assault."
The Wall Street Translation
In markets, the "fighting" is executing trades. Every trade bleeds capital through slippage, spreads, taxes, and emotional wear — your troops.
The investing equivalent of subduing without fighting is patience and capital preservation.
1. Why Frequent Trading Is a Siege
Many traders believe they must always be in the market, contesting every fluctuation. That is assaulting the walls: you may win a few points of profit while costs and mental attrition slowly destroy the account.
"Killing a third of his soldiers while the city remains untaken" has an exact market counterpart: a retail trader operating daily often loses a substantial share of capital annually to spreads, commissions, and short-term capital gains tax — losses entirely unrelated to whether their calls were right. They are the fee for participating.
2. The Four Tiers Mapped to Investing
| Sun Tzu | Investing counterpart |
|---|---|
| Attack strategy | Earn returns through asset allocation, requiring nobody to lose |
| Attack alliances | Cut costs and taxes — directly raises net return |
| Attack armies | Active stock selection, competing head-on with other participants |
| Assault cities | High-frequency trading, shorting strength, catching falling knives |
Note the top two tiers involve defeating nobody. This matches the finding in Strategy Chapter 5 elsewhere in this library exactly: Liddell Hart surveyed twenty-five centuries of warfare and found only six decisive victories from direct assault.
Sun Tzu in the fifth century BC and Liddell Hart in the twentieth produced the same ranking.
3. Cash as a Position
"Not fighting" takes the practical form of holding cash.
The highest form of investing is preserving capital and waiting patiently for the opportunity with overwhelming odds — when it appears, the trade is already won before you click buy, because every condition has aligned.
But one honest qualification: this principle is easily misused as staying in cash indefinitely. The Methods of the Sima Chapter 6 elsewhere in this library supplies the other half — "those who forget war are endangered": staying out of markets for long periods lets inflation erode purchasing power with certainty.
Sun Tzu's "not fighting" means declining battle when conditions are unfavourable, not declining battle forever.
Actionable Trading Rules
- Cash is a position: when markets are choppy and directionless, holding capital is itself a victory — you are conserving strength for the right engagement.
- Do not assault walls: never short a parabolic advance or catch a falling knife in a downtrend. Fighting an emotional extreme is storming a fortified position.
- Use the top two tiers first: before considering stock selection, get costs, taxes, and allocation right — none of which requires defeating anyone.
Relevance to a Retirement Portfolio
This is the chapter of The Art of War that applies most directly to retirement investing.
The objective is not to beat the market but to arrive with the least possible attrition. And attrition in retirement has three concrete sources: costs, taxes, and your own actions during a panic.
Sun Tzu's ranking supplies the order of response:
- Attack strategy — take market returns through an allocation that requires no forecasting
- Attack alliances — reduce certain leakage through low-cost funds and tax-deferred accounts
- Do not besiege — avoid frequent adjustment, especially during violent markets
"A hundred victories is not the highest excellence" carries a particular meaning for retirees: even if every timing decision were correct, the costs and taxes of trading accumulate — and a broad portfolio that never trades often nets more than one that keeps winning.
That is the complete form of subduing without fighting in a retirement context: you do not need to win, you only need to avoid attrition.
