Ancient Wisdom for Modern Times: Lessons from Sun Tzu

“To secure ourselves against defeat lies in our own hands.”
—Sun Tzu

Wealth management and ancient wisdom are surprisingly often aligned. Sun Tzu’s The Art of War, written over 2,500 years ago, provides advice on battlefield strategy, but its advice to leaders on how to handle volatile, uncertain times is applicable to investors today. With your indulgence, let’s see how these ancient concepts can strengthen an investor’s strategies.

Know Yourself and Your Enemy

Sun Tzu wrote that “if you know the enemy and know yourself, you need not fear the result of a hundred battles” (similarly the ancient Greeks wrote on their Temple at Delphi “know thyself”).

Could there be better advice for us today? While perhaps these ancients were speaking about the internal workings of one’s mind, from a financial perspective knowing yourself means understanding your personal facts – income, expenses, holdings and the like. But it does also mean knowing your internal facts based on your risk tolerance, goals, and limitations. Your risk tolerance, time horizon, legacy goals, and family dynamics create a unique financial fingerprint. This is why Financial Planning involves deep discovery – not just about a balance sheet, but about what truly matters to a person. Self-knowledge is the first foundation of a strategy to achieve your life’s goals.

Win Without Fighting

Sun Tzu’s highest ideal was winning before the battle: “The supreme art of war is to subdue the enemy without fighting.”

To me, as applied to wealth management, this means building assets through intelligent positioning and over time rather than aggressive speculation. Too many otherwise successful individuals chase returns or try timing markets perfectly – it’s exhausting and unduly difficult to outperform a well-constructed, diversified strategy over time. To win the investment battle without fighting, we believe in a consistent, disciplined and diversified approach that compounds quietly. In practice, this means focusing on steady progress and avoiding the costly mistakes that derail long‑term success.

Adaptability to Changing Conditions

“Just as water retains no constant shape, so in warfare there are no constant conditions.”

Similarly, your wealth should serve your life as it unfolds, not constrain you to decisions made years ago under different circumstances. When you sell a business, welcome a grandchild, or simply reach a new life stage, your financial plan should adapt accordingly. Nothing stays the same in life forever, everyone needs to adapt to inevitable changes.

Economy of Resources

Sun Tzu warned about prolonged campaigns that drain resources: “no country has ever benefited from prolonged warfare.”

Neither has any person benefited from draining their resources through unnecessary fees, excessive trading costs or poor debt management. Being meticulous about cost efficiency is another key to long-term success and is within an investor’s control.

Discipline During Volatility

Perhaps Sun Tzu’s most relevant wisdom for today’s markets concerns maintaining composure during chaos: “in the midst of chaos, there is also opportunity.”

It is a fact of investing that markets will fluctuate – sometimes dramatically. Economic cycles will continue. Geopolitical events will create uncertainty. Disciplined investors are separated from reactive ones precisely during these moments of volatility. Panic selling during downturns, chasing performance into overheated sectors, or abandoning your strategy based on fear or greed – these emotional decisions destroy wealth. When markets get choppy and chaos seems to reign, in our opinion the best way to maintain order is to maintain a long-term strategy developed in calm times but based on deep self-knowledge.
