A Type of Mistake Involving Self-Blindness Regarding the Investments We Never Made

The Goal Is Not to Avoid Missing Opportunities

After experiencing a painful missed investment that produced great returns, many investors make the wrong conclusion. They conclude: “I need to find and include as many great companies in my investment portfolio before the stock becomes successful by producing huge returns in the next 5 years or decades.”

This sounds logical. However, it is impossible.

The global equity market contains tens of thousands of listed companies.

Very few companies will succeed in ways nobody expected. No investor, regardless of intelligence, experience, resources, or manpower, can identify the vast majority of all future winners in global equities or even in a country-specific stock market.

The objective of investing is to develop a process that consistently improves the probability of identifying very good investment opportunities early on and making good investment decisions thereafter. A strong investment process does not eliminate errors of omission. It reduces unnecessary errors of omission. There is an important difference.

The first is a limitation of being human with only 24 hours in a day. The second is a weakness in the investment process.

Creating an Opportunity Radar

One practical solution is to develop what can be called an “opportunity radar.” An investor should maintain a list of companies and industries worth monitoring even when they are not immediate investment candidates.

These are businesses that possess characteristics of high-quality stocks and potential long-term compounders, as a recap:

The purpose of this list is not to buy everything immediately. The purpose is awareness.

Many exceptional and great companies do not become attractive investments at the same time. Typically, the stock of an exceptional or great company may be too expensive today. A financial crisis or another economic crisis may cause all stocks to drop drastically, creating an extremely attractive entry point. A temporary problem may later create a very attractive entry point. A business transformation may take several years before the market recognises its value.

Without prior knowledge, investors may discover these opportunities too late. By maintaining awareness and doing adequate research beforehand, investors increase the chance of recognising important developments early.

The investor who followed AMD for years had a significant advantage over someone who discovered the company only after its stock had already multiplied. Knowledge compounds just like capital.

Great Investors Are Not Omniscient — They Are Prepared

Many people misunderstand the success of elite investors such as Warren Buffett and Charlie Munger. They are often described as people who can identify exceptional and great companies effortlessly.

However, their advantage is not perfect prediction of where the stocks of these companies may end up in a few years up to decades from now; hence the margin of safety required in value investing. Their advantage is preparation.

They spend years studying businesses, industries, management teams, and economic patterns. When opportunities appear, they already possess a foundation of knowledge. They do not begin researching from zero during economic recessions, financial crises, or severe geopolitical shocks.

This is similar to professional athletes. A tennis player does not become excellent during the championship match. The preparation happens years before the important moment.

Investing works the same way. When a wonderful company temporarily becomes misunderstood by the market, the prepared investor has the confidence to act. The unprepared investor sees only uncertainty.

The Importance of Maintaining a Watchlist of Great Businesses

A common mistake among investors is only researching companies after they become attractive. This creates an investment timing problem.

By the time a stock appears interesting on social media or financial news, the opportunity would most likely have changed, and the risk-reward profile of the stock would have shifted to the detriment of new investors into the stock, where traders and investors who bought the stock much earlier would sell to the new traders and investors to actualise their profits.

A better approach is to study companies before they become obvious. For example, an investor who studied Nvidia before artificial intelligence became the dominant market theme would have had years of understanding regarding its technology, ecosystem, competitive position, management quality, and customer relationships. When AI demand accelerated, the investor could evaluate the opportunity with deeper understanding. They were not reacting. They were updating.

Balancing Focus and Curiosity

One of the hardest challenges for long-term investors is finding the right balance between focus and curiosity. Too much focus creates blindness — an investor who only studies one industry may miss important structural changes elsewhere. Too much curiosity creates distraction — an investor constantly chasing new ideas may never develop deep expertise.

The ideal approach is selective curiosity. Continue expanding knowledge, but maintain strong awareness of existing areas of competence.

The best investors are often specialists who remain intellectually curious. They have a strong foundation but remain open to learning.

The Role of Humility in Investing

For many investors, the experience of missing AMD, Nvidia, Amazon, or other great businesses teaches an important lesson: the market will always produce surprises. No investor has complete knowledge. No investor can accurately predict every technological change, consumer behaviour shift, or competitive development.

Humility is therefore essential. A humble investor understands: “I may be wrong.” “My assumptions may change.” “A company I ignore today may become important tomorrow.”

This mindset creates better decision-making. The opposite mindset creates overconfidence. Overconfident investors often believe they have already understood everything about a company. They stop learning. They ignore evidence that challenges their beliefs. Eventually, reality proves them wrong.

Avoiding the Two Extremes

After missing a great investment, investors can move toward one of two extremes.

Both approaches are harmful. The correct approach is disciplined conviction. Invest when the vast majority of evidence supports the decision. Accept uncertainty. Understand that investing always involves incomplete information.

The True Lesson From Missed Opportunities

The lesson from missing AMD is not “buy every semiconductor company.” The lesson is not “never miss another winner.”

The lesson is: develop a process that allows you to recognise exceptional opportunities when they appear substantially sooner than other investors.

A great investor does not need to catch every sector rotation. They need to recognise enough important sector rotations where attractive investment opportunities will be available. The ocean of all global equity markets will always produce opportunities. The investor's responsibility is to be prepared when the right sector rotation arrives.

The Difference Between Regret and Growth

Regret itself is not harmful. Used correctly, regret can improve an investor. A missed opportunity can reveal:

The problem occurs when regret becomes emotional rather than analytical.

The first question creates frustration. The second creates progress.

The Ultimate Competitive Advantage: Knowing What Matters

In a world overflowing with data and information, investors face a unique challenge. The problem is no longer access to data and information. The problem is filtering and selecting the most relevant information to make a comprehensive analysis of a stock.

Every day, investors are exposed to market commentary, financial news, analyst opinions, social media discussions, economic forecasts, and short-term price movements. The vast majority of this information does not improve investment decisions.

Great investors understand that attention must be protected. They know that every unnecessary distraction reduces their ability to focus on important decisions. The ability to ignore noise is therefore a competitive advantage.

Final Reflection: The Stocks We Miss and the Investor We Become

Every experienced investor eventually has a list of companies they wish they had purchased earlier. These companies become permanent reminders of missed opportunities. However, they should not become sources of endless regret. The purpose of investing is not to create a perfect history. No investor can do that. The purpose is to continuously improve judgment.

My missed investment in AMD represents a valuable lesson. It reminds investors that:

The best investors are not those who never miss anything. They are those who learn from what stocks they missed. They understand that the future will always contain opportunities that seem obvious in hindsight. Their responsibility is not to predict everything. Their responsibility is to build the knowledge, patience, and discipline required to recognise the opportunities that truly matter.

Because ultimately, the greatest investment mistakes are not always the companies we bought and lost money on. Sometimes, they are the wonderful businesses we understood, watched, admired, and then allowed to pass by.
