Imagine you're thinking of buying a small, local ice cream shop. You ask the owner how much profit the shop makes. He excitedly tells you, “Last year was incredible! We made $100,000!” That sounds fantastic. But as a savvy investor, you dig a little deeper. You discover that last year, the town hosted a massive, once-in-a-century summer festival right outside the shop's door, and a competing shop across the street was closed for renovations. The year before, a freezer broke, costing $20,000 in repairs and lost inventory, and profits were only $30,000. The year before that, a normal year, it was $60,000. Which number tells you the most about the shop's real earning ability? The spectacular $100,000? The dismal $30,000? Or the “boring” $60,000? A value investor would argue that none of these single-year figures are truly representative. Instead, you'd want to smooth out these peaks and valleys to find a more reliable average. You'd ignore the one-time festival boost and the one-time freezer disaster. This process of finding the shop's typical, repeatable, underlying profitability is the essence of calculating its Normalized Earnings Power. In the world of big public companies, the “noise” is even louder. Reported earnings—the number you see headlining the news every quarter—are often distorted by:
Normalized Earnings Power is the antidote. It's the disciplined act of an analyst stepping back and asking: “Forget the drama of this specific year. Under normal economic conditions, without any weird one-off events, how much money can this business realistically be expected to earn year in and year out?” It's about finding the steady hum of the engine, not the occasional roar or sputter.
“The value of a business is the present value of the net cash flows that it will generate over its lifetime. That's it. The only thing that complicates it is that you don't know what those cash flows will be.” - Warren Buffett 1)
For a value investor, understanding Normalized Earnings Power isn't just a neat trick; it's fundamental to the entire philosophy. It's the difference between being a speculator and an investor. 1. It Anchors Valuation to Reality: The stock market is a manic-depressive beast. It gets wildly optimistic when a company reports a record quarter and brutally pessimistic after a bad one. A value investor ignores this noise. By calculating Normalized Earnings Power, you create a stable, conservative anchor for your valuation. If a cyclical company's stock price soars to 30 times its peak earnings, you know it's wildly overvalued because you've calculated that its normalized P/E is closer to 60. Conversely, if that same company is trading at 5 times its recession-level earnings, you might see a bargain because you know its normalized earnings are much higher. 2. It's the Foundation of the Margin of Safety: The concept of margin_of_safety, championed by Benjamin Graham, is about buying a security for significantly less than its underlying value. But how do you determine that value? If you base your valuation on a single year of peak earnings, your estimate of intrinsic_value will be inflated, and your margin of safety will be a dangerous illusion. Using a conservative, normalized earnings figure gives you a much more robust and defensible estimate of value, ensuring your margin of safety is real. 3. It Forces a Long-Term Business Perspective: Calculating normalized earnings requires you to look back 5, 7, or even 10 years into a company's history. This process forces you to think like a business owner, not a stock trader. You'll see how the business performed through different economic climates. Did it remain profitable during the last recession? How volatile are its sales and margins? This long-term view is critical to understanding the quality and durability of the business itself, which is far more important than a single earnings report. In short, Normalized Earnings Power is a tool of reason against the market's emotion. It replaces a single, potentially misleading snapshot with a more complete, long-exposure photograph of a company's profitability.
There is no single, official formula. It's more of an analytical art based on conservative principles. However, a common and robust method involves these steps:
The number you get is your estimate of the company's “true” earning power in a typical year. This is the figure you should use for valuation metrics.
A key insight is comparing a company's current earnings to its normalized earnings. If current earnings are far above the normalized figure, the business is likely at a cyclical peak, and its high stock price may be fragile. If current earnings are far below the normalized figure, the business may be in a temporary trough, potentially presenting a classic value opportunity.
Let's compare two fictional companies over the last five years.
Here are their reported Earnings Per Share (EPS) for the last five years:
Year | Cyclone Cycles EPS | Evergreen Utilities EPS | Notes for Cyclone |
---|---|---|---|
2023 | $5.00 | $2.10 | Economic boom; peak sales. |
2022 | $3.50 | $2.05 | Strong economy. |
2021 | -$1.00 | $2.00 | Company had a one-time $2.00/share factory shutdown cost. |
2020 | $0.50 | $1.95 | Mild recession. |
2019 | $2.00 | $1.90 | Normal year. |
Analysis: 1. The Naive Investor: Looks at 2023 earnings. They see Cyclone earning $5.00 and Evergreen earning $2.10. If both stocks trade at $42, the naive P/E ratio is:
The naive investor buys Cyclone Cycles, thinking it's a bargain. 2. The Value Investor (Using Normalization):
Conclusion: After normalization, the picture looks very different. Evergreen's P/E of 21x is consistent. But Cyclone's “cheap” P/E of 8.4x was an illusion based on peak earnings. Its more realistic Normalized P/E is 17.5x. While this is lower than Evergreen's, it's more than double the naive calculation and reveals a much riskier proposition at the current price. The value investor avoided a classic “value trap.”
