In the realm of investing, uncertainty is a universal truth, widely accepted by market participants. However, amidst the unpredictable fluctuations of the market, is there a form of certainty that we can rely on? The answer is yes.
Investment certainty does not lie in forecasting stock price movements—because stock prices themselves are inherently volatile and unpredictable. Instead, certainty can be found in two deeper dimensions.
1. Certainty in Investment Targets: Understanding is More Important Than Prediction
Certainty in an investment target refers primarily to the depth of understanding of a company’s fundamentals. When we speak of a company’s certainty, we are not referring to its stock price movements, but rather its growth potential and intrinsic value.
Nothing in life is absolutely certain, and investing is inherently a bet on uncertainty. The more thoroughly we understand a company or an industry, the higher our chances of success. This deep understanding allows us to identify opportunities that few can see—whether it’s a new direction for a company or subtle shifts in an industry’s landscape. This “certainty” does not guarantee that a company will develop exactly as we anticipate, but it means that when a company reaches a certain stage, we can foresee the new competitive advantages and performance increments that may emerge over the next three to five years.
This forward-looking vision is valuable precisely because it is scarce. If everyone could see the same opportunities, the market would have already priced them in. The best investment opportunities often arise from insights held by just a few.
2. Certainty for Investors: Control What You Can, Accept What You Cannot
The second dimension of certainty comes from the investor themselves, particularly in terms of risk management.
In the investment world, the primary reason for failure is not incorrect judgment, but the loss of control over risk. When extreme market conditions arise, permanent losses of capital can make recovery difficult and prolonged.
Investors create real certainty in the dimension of risk control by:
- Buying with a margin of safety: Although opportunities with significant margins of safety are becoming rarer, patience will eventually reward investors with such moments. The market’s emotional swings inevitably create instances of irrational pricing.
- Avoiding leverage and maintaining flexibility: By not over-leveraging, staying flexible with positions, and managing asset allocation, investors can control areas within their reach. In a world surrounded by uncertainty, these self-imposed principles form the solid foundation of certainty.
The Dual Mastery of a Mature Investor
When investors excel in both dimensions—understanding the target and managing risk—they advance on the path to becoming mature investors.
In the long term, investment returns are directly proportional to the maturity of one’s investment philosophy. This maturity manifests in the ability to avoid overconfidence in predicting the unpredictable, while still adhering to principles and discipline despite market fluctuations.
Mature investors understand that true certainty does not exist in the market itself, but within their cognitive framework and risk boundaries. They do not seek absolute guarantees but, in acknowledging the inherent uncertainty of the world, create relative certainty within their circle of competence.
Investment is essentially a dual process of cognitive and emotional development. By recognizing the inevitability of uncertainty, investors can still find limited but real forms of certainty, all while adhering to controllable principles in an unpredictable market. This may be the deepest dialectic of the art of investing, rewarded by the market only for those who remain both humble and steadfast.
