Valuing stocks is nothing more than the process of estimating the real or intrinsic value of a company. This estimate is then compared to the price at which the stock is trading in the market. Why is this comparison so important? Because it helps us identify whether a stock is undervalued or overvalued. When the market price is lower than the intrinsic value, an opportunity arises to buy at a discount; similarly, if the price significantly exceeds the real value, it might be the right time to sell and secure profits.
This idea of seeking discrepancies between price and intrinsic value is one of the pillars of value investing, a strategy adopted by some of the most successful investors in history, such as Warren Buffett, Joel Greenblatt, and Pat Dorsey.
Fundamental Analysis: The Path to Intrinsic Value
Fundamental analysis focuses on studying a company’s financial health and growth potential. This analysis covers aspects such as:
Financial Statements: Balance sheet, income statement, and cash flow statement.
Profitability Ratios: Indicators measuring efficiency and profit-generating capacity.
Debt and Solvency: Evaluation of capital structure and debt levels.
Business Prospects: Business segments, market positioning, and future growth potential.
There are two essential methods to determine a stock’s real value:
Discounted Cash Flow (DCF) Valuation: This method involves projecting a company’s future cash flows and discounting them at a rate that reflects the cost of capital, thereby obtaining an estimate of present value.
Multiples Valuation: This approach compares a company with similar ones using ratios (such as P/E, P/B, among others) to determine whether its market price aligns with the industry average.
The Difference Between Market Price and Real Value
A fundamental premise in stock valuation is that the market price does not always reflect a company's real value. This is because financial markets are inherently volatile, influenced by emotional factors such as greed, fear, euphoria, and panic. As investor Joel Greenblatt famously said:
"Prices fluctuate more than value."
This gap between price and value is precisely where opportunity lies. While stock prices may change abruptly in the short term due to investors’ emotional reactions, a company’s intrinsic value moves slowly and gradually, supported by solid economic fundamentals.
The fact that the market is not perfectly efficient is evident in several historical examples. Even large-cap companies, generally considered stable benchmarks, can experience significant price fluctuations. For instance, in a relatively low-volatility year like 2019, the ten largest-cap companies saw price differences of up to 44% between their 52-week highs and lows. A concrete example is Facebook, which traded between $123 and $209 in that period, showing a variation of nearly 70%. This phenomenon demonstrates that even well-established and widely followed businesses always present opportunities to buy at a low price and sell at a high price.
Market Psychology and Investor Behavior
Analyzing market behavior reveals that emotions play a crucial role in price fluctuations. Greed and fear often cause investors to deviate from a rational strategy. It is common to see that, during moments of euphoria, many buy without stopping to assess whether the price is fair, while in times of panic, mass selling occurs, often creating buying opportunities.
An interesting concept related to this phenomenon is the bystander effect. Just as in the case of the Kitty Genovese murder, where each witness assumed someone else would take action, many investors refrain from thoroughly analyzing large companies, assuming that “everyone is already doing it.” However, this lack of analysis can be misleading because, despite their size, large corporations are also affected by market emotions and can trade far from their real value.
A phrase that summarizes this approach is:
"Don’t let exuberant markets get to your head; don’t let pessimistic markets get to your heart. The volatility of the mind is far more dangerous than stock price volatility, and an objective mindset is key to investment success."
Similarly, we can cite Napoleon Bonaparte, whose definition of a military genius was—"someone who can do the ordinary things when everyone around them is going crazy." This phrase is perfectly applicable to investing. It highlights the importance of staying calm and following a fundamentals-based strategy, regardless of market frenzy.
Benjamin Graham, another giant of value investing, summarized this thinking with a key idea:
"Price fluctuations hold significant meaning only for the true investor, as they provide opportunities to buy when prices drop sharply and to sell when they rise considerably."
This advice urges us to be fearful when others are greedy and greedy when others are fearful—a philosophy that has guided Warren Buffett throughout his career. In fact, Buffett has ironically stated that if markets were completely efficient, he would be begging on the streets, underscoring the importance of identifying and capitalizing on market inefficiencies.
Conclusions and Next Steps
Stock valuation is an essential skill for any investor aiming for long-term profits. Understanding a company's intrinsic value and comparing it to its market price allows us to identify opportunities where the gap between the two offers a significant profit margin. Additionally, rigorous fundamental analysis and emotional control during periods of euphoria or panic are key factors for investment success.
