Always arrive first to the empty battlefield to await the enemy at your leisure.
If you are late and hurry to the battlefield, fighting is more difficult.
You want a successful battle.
Move your men, but not into opposing forces.
Art of War 6:1.1-4
Nature abhors vacuum; human nature prefers crowd. Since strategy is all about advancing positions, "empty" battlefields, gives us position of strength. Be early enough to spot a changing appetite for various asset classes, well before several others do so. By doing so, achieves several great advantages.
One, we have better prices. Two, when many others realize it, human nature, like birds, will start to flock towards this investment, causing price movement. By the time all others see the benefit, and start crowding, is when you know that "empty" ground is way too congested for comfort, and the early birds may start flying away in opposite directions, having already fed themselves well. We want to be among the early birds. Timing (as Sun Tze proposed, is thus reinforced in this stanza above).
When the enemy is fresh, you can tire him
When the enemy is well fed, you can starve him
When he is relaxed, yu can move him
Art of War 6:1.9-11
I wish to highlight only the underlined passage. The enemy is Mr. Market. In a situation when prices are well into their obvious high, and many start talking about it, is when we should consider "starving" it, by not adding on more positions.
Sun Tze alludes that the "ground" is the source of strength. The "ground" is market actions or market players' inclination. The market trends up only because it gets its strength from the players. But the "climate" changes; ie global forces, fx currencies, LIBOR spreads, yields, fiscal policies change over time. These all make a strong position weak over time.
Strength is always temporary. Just as when the enemy is well fed, over time, it will grow hungry again.
A large part of our investment strategy(defined as ever changing plans according to Sun Tze) is to work alongside the nature's forces, and never against it.
Identifying when the market is hungry and well fed, helps us determine when we should attack or simply walk away.
This reemphasises the importance of knowledge and information.
