Improve Your Investing Skills with Warren Buffett’s Advice

Warren Buffett, the renowned investor, has once again shared his wisdom in his annual shareholder letter. Released on February 24, the 2023 version of his letter contains valuable insights into the world of investing. One of the key takeaways from Buffett’s letter is his criticism of the commonly used net income metric. While many investors rely on this metric, Buffett refers to it as “worse than useless.” In this article, we will explore Buffett’s perspective on net income and how you can become a smarter investor by using it effectively.

Net Income vs. Operating Income

Buffett emphasizes the difference between net income and operating income in his letter. He points out that Berkshire Hathaway’s net income has undergone significant changes over the past three years. However, he finds something amiss with these alterations. Although net income is a figure that public companies are required to report, Buffett suggests that investors should approach it with caution.

The main discrepancy between net income and operating income lies in unrealized capital gains and losses. These refer to the changes in the value of stocks owned by Berkshire Hathaway. For individual investors, unrealized gains or losses only come into play when stocks are sold, affecting capital gains tax. However, since Berkshire Hathaway is a holding company, it reports its equity positions as assets. Consequently, changes in the value of these positions, which can be as high as $5 billion per day, strongly impact the reported net income or loss for the quarter. Yet, these fluctuations have little connection to the company’s operations or long-term stock movements.

Using Net Income Effectively

While Buffett criticizes net income, he acknowledges that it can be a useful starting point when evaluating a business. It shouldn’t be relied upon as the sole factor in decision-making, but rather as a part of a comprehensive analysis. By understanding the context surrounding a company’s net income, investors can gain insight into its overall performance.

Buffett’s investment philosophy focuses on selecting great businesses with strong management, enduring products, and a competitive edge. When evaluating Berkshire Hathaway, for example, investors should consider factors that affect the company’s business, such as its stock positions and their performance. However, it is crucial not to overlook the daily operations of the business by excessively focusing on unrealized gains and losses.

Looking at the Whole Picture

Net income is a popular metric because it represents the bottom line of a company. While some businesses may use profitability metrics like EBITDA (earnings before interest, taxes, depreciation, and amortization) to provide insights into their core operations, Buffett finds these metrics even more useless than net income. Management teams often rely on these metrics to create a positive image, but they should only be viewed as additional data points.

Rather than relying too heavily on any one metric, investors should review all of a company’s financial statements over time to make informed investment decisions. Net income can serve as a starting point, but it’s important to consider a comprehensive range of financial information.

To become a smarter investor, it’s crucial to follow Warren Buffett’s advice in evaluating companies. By understanding the limitations and context of metrics like net income, you can gain a clearer perspective on a company’s true performance. Remember, investing is about assessing the whole picture, not just relying on a single metric.
