Art of War Ch. 3: Strategic Manoeuvre — Sector Rotation and the Indirect Approach

"Manoeuvre is the art of throwing troops upon the enemy's rear communications without exposing one's own." — General Jomini

Military Context

Strategic manoeuvre is the art of turning a flank. A capable commander never assaults a strong position frontally at ruinous cost but moves around it, severs the supply line, and forces the enemy to fight at a disadvantage or surrender.

Jomini stresses that manoeuvre demands anticipatory speed and concealment — completing the deployment before the enemy realises the position has been turned.

This aligns with the core argument of Strategy elsewhere in this library: Liddell Hart demonstrated the same thing systematically a century later — decisive victories in history rarely come from frontal assault.

The Wall Street Translation

A frontal assault in trading — chasing after a 50% run and saturation media coverage — means low returns and high risk. Strategic manoeuvre corresponds to pre-emptive sector rotation.

1. Pre-Emptive Sector Rotation

Capital rotates between sectors with the macro regime:

• Early recovery: industrials, materials, consumer discretionary
• Late expansion: technology, communications, energy
• Stagflation or slowdown: utilities, consumer staples, healthcare, commodities and gold

Position before the retail crowd arrives.

2. Avoiding Crowded Trades

When a sector is heavily crowded — hot technology at a hundred times earnings — do not attack frontally. Look for second-order beneficiaries of the same secular trend trading at a fraction of the valuation.

3. Protect Your Line of Retreat

Maintain trailing stops and ample liquidity so you can withdraw safely when the macro narrative reverses. Jomini repeats that no manoeuvre may be bought at the cost of exposing your retreat.

4. The Real Difficulty of Manoeuvre

Honesty is required: pre-emptive rotation demands identifying macro turns before the market, which is extremely hard.

Rotation is obvious on a chart afterwards and deeply ambiguous in the moment. Much of the capital attempting to rotate in practice buys the top of each sector and sells the bottom — because the signals identifying an "emerging" sector usually appear only after it has already risen.

This matches Big Debt Crises Chapter 6 elsewhere in this library: macro understanding should shape long-run allocation rather than drive frequent repositioning.

Actionable Trading Rules

1. Look for second-order beneficiaries when crowding is high: reasonably valued supply-chain names in the same trend often offer better risk/reward than leaders.
2. Never manoeuvre without a predetermined retreat: define exit conditions and stop placement before entering.
3. Distrust your own rotation calls: if recent strong performance is your reason for rotating in, that is chasing rather than anticipation.

Relevance to a Retirement Portfolio

For retirees the correct use of this chapter is defensive rather than offensive.

Active rotation requires repeatedly correct macro judgment, which is empirically very hard. But avoiding obviously crowded trades — extreme valuations, media euphoria, universal discussion — requires recognising only a few public signals.

Rebalancing is itself a mechanical rotation requiring no foresight: it trims a sector automatically when appreciation overweights it and adds when it falls. For retirement money, that judgment-free mechanism is far more reliable than active rotation.
