The essence of Warren Buffett’s value investing lies in holding great enterprises for the long term at reasonable prices. The primary criterion for great enterprises is to possess broad and unbreachable economic moats, namely structural advantages that enable enterprises to fend off competition and maintain strong profitability over time. Therefore, within the value investing system, the core and most challenging task is not to predict short-term market trends, but to identify enterprises with genuine long-term competitive edges. In other words, seeking moat-endowed enterprises is essentially looking for assets with sustainable intrinsic value.
I. Screening Enterprises Is Like Choosing a Lifetime Partner
We can understand this principle via a vivid analogy: how to pick a partner with steady wealth-generating potential.First, look at the present. Does the person have the ability to earn money now? Does such wealth come from personal capability, family background or temporary luck?Second, look ahead to the future. If solid returns have not yet materialized, does the industry involved have room for growth? Does the individual have the potential for steady self-improvement?
The same logic applies to screening moat enterprises. The key is to distinguish whether an enterprise’s profit-making capacity is sustainable, and confirm that such capacity stems from inherent competitive advantages rather than short-term industry dividends or accidental factors.
In his work The Economic Moat, Pat Dorsey systematically sorted out this logic and turned it into operable analytical approaches, building a practical framework connecting theories with real investment practices.
II. Practical Three-step Method: From Quantitative Screening to In-depth Qualitative Analysis
Screening moat enterprises is a process that proceeds from superficial data down to inherent nature, which can be summed up into three core steps.
1. Confirm core indicators measuring profit-making capacity
First of all, investors need core criteria to gauge an enterprise’s profit efficiency. Two most widely adopted financial indicators are as follows:Return on Equity (ROE), which measures a company’s efficiency in generating profits with shareholders’ capital and is highly valued by Buffett;Return on Invested Capital (ROIC), a more rigorous indicator that eliminates the distortion caused by high debt on ROE and directly reflects the real rate of return generated by all invested capital including equity and liabilities.
A commonly recognized quantitative threshold is that enterprises with a 5-to-10-year average ROE above 15% and average ROIC exceeding 10% are more likely to own solid economic moats. This step serves as a preliminary financial check, verifying from historical data whether an enterprise can deliver stable and substantial returns on capital.
Based on long-term research experience, enterprises capable of sustaining high ROIC have generally established certain structural competitive advantages.
2. Conduct screening in a top-down or bottom-up manner
After finishing quantitative screening, investors may adopt proper approaches for further analysis.
The bottom-up approach starts directly with historical ROIC and ROIC data to select enterprises with high investment returns, before further studying their industry attributes and growth potential. This is the most commonly adopted method in actual investment.
The top-down approach prioritizes selecting industries with long-term profit potential, then picks out more profitable and structurally sound enterprises within such industries. Some industries inherently boast higher profit ceilings, which tend to nurture more moat enterprises.
The ideal investment strategy is to discover top-performing enterprises within highly profitable industries, which requires rational judgment on both industry prospects and corporate competitive structures.
3. Dig into sources of high returns to verify economic moats
High ROIC alone is far from sufficient. The critical question is whether such outstanding profits derive from solid economic moats or merely temporary industry dividends and vacant competitive markets. Investors need to classify and verify specific types of economic moats at this stage.
For instance, leading investment banks such as Goldman Sachs build competitive barriers not only through brand influence and scale advantages, but also via established client networks and high customer switching costs. It is extremely difficult for newcomers to match their scale and market credibility, enabling such institutions to maintain lasting profitability. Quantitative data provides clues, while qualitative analysis serves as the key to confirming genuine economic moats.
III. Avoid Two Common Misconceptions to Safeguard Investment Principal
The investment philosophy of holding great enterprises for the long term at reasonable prices is widely appealing, yet investors easily fall into two typical pitfalls in practice.
1. Knowing the phenomenon without understanding the essence
Some investors rush to make purchases merely based on high historical ROE or ROIC figures, without digging deep into the underlying drivers of strong profits. For example, Changchun High-Tech once achieved remarkable returns driven mainly by product cycles rather than solid long-term moats. Without clarifying the essence of profit sources, high ROE remains nothing more than a superficial phenomenon instead of proof of genuine competitive strengths.
2. Believing premium enterprises justify any entry price
Another prevalent misconception is that high-quality enterprises can be bought at any valuation, with time eventually offsetting excessive premiums. In fact, purchase prices always determine final investment returns. Even top-tier enterprises like Kweichow Moutai may bring prolonged yield setbacks if bought at sky-high valuations. Economic moats guarantee corporate quality yet cannot eliminate valuation risks.
To sum up, economic moats determine whether an enterprise is outstanding, while reasonable entry prices decide whether an investment is worthwhile. Neither can be dispensed with.
Conclusion
Identifying corporate economic moats is a core skill that value investors need to hone consistently. By applying the systematic three-step method covering financial examination, directional screening and qualitative verification, and staying alert to common misconceptions, investors can gradually build sound judgment on corporate competitive structures.
From a long-term perspective, investment success never relies on frequent trading, but on staying partnered with enterprises that keep deepening their moats and delivering steady capital returns. In essence, genuine value investing is a journey cultivating patience and rational judgment, with time acting as the sole criterion to test such judgment.
