When an investment strategy fails, should you really give up?

Today’s Market

On the first trading day of April, the A-shares market opened strongly. By the close, the Shanghai Composite Index rose 1.46% to 3,948.55 points, the Shenzhen Component Index increased by 1.70%, the ChiNext Index gained 1.96%, and the Sci-Tech Innovation 50 Index performed the best, soaring 3.33% throughout the day.

In terms of sectors, the pharmaceuticals and biotech sector led with a 3.99% increase, followed closely by communications, media, and electronics. Meanwhile, traditional cyclical sectors such as utilities, coal, and oil & petrochemicals experienced adjustments, with clear signs of capital shifting toward growth-oriented tracks.

All Investment Strategies Have Weaknesses

Every remarkable investor and investment strategy has its flaws. This principle seems simple, but in the ebb and flow of the market, few truly understand and accept it.

Every successful investment strategy is built on a specific market environment or assumption. Value investing relies on the market mispricing quality assets, growth investing bets on a company’s future explosive potential, and trend following capitalizes on market sentiment inertia. These strategies are effective because they align with market operation rules during certain phases. But rules always change, and market styles rotate continuously. When the environment shifts, strategies that once worked flawlessly can hit bottlenecks or even temporarily fail. This isn’t a flaw in the strategy itself but a reminder that every method has its applicable boundaries.

The problem is that most people tend to be emotional and find it difficult to adhere strictly to logic. When they see a strategy working continuously, they often become overly enamored, viewing short-term success as an eternal secret, even blindly increasing their bets. Conversely, when market conditions change and the strategy begins to fail, they quickly shift from infatuation to disappointment, dismissing previously validated logic and abandoning positions at the worst possible moments. This rapid switch from love to disappointment is driven by the same emotional force—overreacting to short-term results.

Behind this reaction are two human weaknesses. First is confirmation bias: people tend to seek information that confirms their existing beliefs and ignore evidence to the contrary. When a strategy works, investors unconsciously find more reasons to support it, strengthening their confidence; when it fails, they rush to find reasons for the failure, often mistaking short-term volatility for long-term malfunction. Second is loss aversion: the pain of losses far exceeds the pleasure of gains, leading to irrational decisions when facing losses, such as cutting losses at the bottom.

Thus, we often see this cycle: a strategy performs well for a period, attracting large capital inflows; when it starts to decline, the same capital quickly withdraws, leaving panic selling and low-priced chips. The tragedy of buying high and selling low repeats again and again.

True mature investors understand the difference between short-term strategy failure and the collapse of long-term logic. They don’t dismiss a proven method after a single setback, nor do they ignore hidden risks after temporary success. They realize that every strategy has inherent weaknesses, and the key isn’t to find a perfect, flaw-free plan but to understand these weaknesses and stay calm when they appear.

They know that the effectiveness of a strategy is often inversely proportional to its popularity—when everyone is chasing a method, it may already be near the point of failure; when it’s widely questioned, it might actually be the best time to leverage it.

More importantly, mature investors learn from mistakes rather than simply giving up. They review their decisions, distinguishing between limitations of the strategy itself and execution errors. They understand that each phase of strategy failure is an opportunity to reassess and optimize their investment system, not a reason to start over. This ability to iterate continuously is the key to long-term success.

In the world of investing, there is no perfect strategy—only strategies that suit you. Accepting imperfection helps maintain resolve amid market fluctuations. Just as a tree cannot grow upward forever, no strategy can outperform the market indefinitely. The real focus isn’t on finding the eternal “Holy Grail,” but on finding a method you understand and can stick to, staying clear-headed when it works and patient when it fails.

This calmness stems from a deep understanding of investment’s nature—every success is a game of probabilities, and true advantage comes from remaining rational even when most people are emotional.

Investment Message

Investing is a marathon, not a sprint. Short-term market fluctuations are full of stories, but the real value is created through the power of compound interest over time. Stay rational, disciplined, and grow together with quality companies. Moving slowly ensures you can go far.
