What is Abnormal Earnings Valuation?

Understanding the world of investment and business valuations can often seem complex. However, armed with the right knowledge and tools, investors can make informed decisions that yield rewarding outcomes. This article aims to shed light on the Abnormal Earnings Valuation model, an essential tool for predicting a company's future stock prices based on its book value and earnings.

Abnormal Earnings Valuation Model

The Abnormal Earnings Valuation (AEV) model, also known as the residual income model, is a unique approach for determining a company's equity value. Unlike traditional methods that solely focus on cash flows, the AEV model combines the company's book value and its expected earnings. This blend provides a more holistic view of a company's worth, taking into account not only the physical assets but also the company's ability to generate profit.

Core Principles of the Abnormal Earnings Valuation Model

The heart of the AEV model lies in its ability to forecast future stock prices. The model proposes that investors should be willing to pay more than a company's book value if its earnings exceed expectations and less if earnings fall short of projections.

At its core, the AEV model attributes the part of a stock's share price that deviates from its book value to the company's management expertise. Thus, it indirectly measures the effect of management's decisions on company performance, making it a valuable tool for investors and analysts alike.

The AEV Model's Significance in Business Valuation

The AEV model assumes a central role in business valuation, especially for firms that are rich in human capital or possess significant cash flows but lack substantial hard assets. For such companies, traditional valuation methods using hard assets might not reflect an accurate picture of their worth.

In these cases, the AEV model provides a robust alternative, with future cash flows given substantial weight during the valuation. This flexibility allows the model to accommodate varying business structures and operational models, making it an adaptable tool for a wide range of companies.

Comparing the AEV Model to Other Valuation Models

Several other cash flow-based valuation methods exist, including the Dividend Discount Model (DDM) and other Discounted Cash Flow (DCF) models. However, these models might not be suitable for every company. For instance, they might not be appropriate for a company that has an unpredictable dividend pattern or has reported negative free cash flow for several years.

In contrast, the AEV model extends beyond just cash flows. It considers both the book value and earnings exceeding the expected baseline, thereby providing a more comprehensive valuation. In certain scenarios, the AEV model can anchor the valuation in current earnings instead of book value, thereby increasing its applicability.

Risks and Adjustments in the AEV Model

Like all valuation models, the AEV model carries its share of risks. The primary risk lies in the model's performance accuracy, often referred to as model risk. If the model fails to accurately predict future stock prices, it can lead to unfavorable investment outcomes.

Moreover, the company's book value per share used in the model must be adjusted for any significant changes, such as share buybacks or other events. This ensures that the valuation remains accurate and relevant, reflecting the company's current financial status.

The Power of the AEV Model

In conclusion, the Abnormal Earnings Valuation model offers a unique approach to business valuation. By considering both book value and expected earnings, it provides investors with a more comprehensive view of a company's equity value. It's a powerful tool, particularly when assessing companies rich in human capital or possessing substantial cash flows but fewer hard assets. As with any financial tool, however, the AEV model should be used judiciously, taking into account its potential risks and limitations.

How the AEV Model Works

The AEV model works by first determining the expected equity book value for the next period. It does this by adding the earnings less the required return on equity to the equity book value of the previous period. This generates an estimate of the book value for the next period.

The AEV, also called abnormal earnings, is then calculated by subtracting the required return on equity from the earnings of the next period. This difference is the extra earnings or abnormal earnings.

The valuation then continues by summing all future abnormal earnings and discounting them to present value. The sum of this present value and the current book value of equity is the intrinsic value of the stock, according to the AEV model.

AEV Model in Practice: Its Uses and Limitations

Investors use the AEV model as one of the many tools in their toolbox for company valuation. The model can be particularly useful for businesses that have significant intangible assets or human capital. Tech companies, pharmaceutical companies, and other similar businesses often fall into this category.

However, as with any model, the AEV model comes with its limitations. Its accuracy heavily depends on the accuracy of the underlying assumptions about future earnings and required return on equity. Furthermore, it might not be appropriate for businesses with very unstable earnings or those that don't retain a portion of their earnings.

The Abnormal Earnings Valuation model is a robust method for company valuation that goes beyond the scope of traditional cash flow-based models. By incorporating both book value and expected earnings, it offers a more holistic view of a company's equity value.

However, like any tool, its efficacy rests in its application. Therefore, it's critical for investors to understand their portfolio companies well and the appropriateness of different valuation models for each. It's also important to keep in mind that the AEV model, while powerful, should be just one of many considerations when making investment decisions.

In essence, the AEV model provides an additional lens through which investors can view a company's financial health and growth potential, contributing to a more informed and potentially successful investment strategy.


The abnormal earnings valuation method is one in which the future cash flows of a business are given significant weight in a valuation, especially when there are not many hard assets to use for valuation purposes.

If a company is rich in human capital or has significant cash flows, whether or not it has many hard asset or book value, the Abnormal Earnings Valuation Model can be the most useful method for arriving at an accurate valuation of a business and its stock.

Other valuation methods using cash flows exist, such as the Dividend Discount Model (DDM) and other Discounted Cash Flow (DCF) models, but these may not be appropriate for a company that has an unpredictable dividend or that has a negative free cash flow for a number of years yet.

These also only look at the cash flows, whereas abnormal earnings valuation looks at book value plus earnings in excess of the expected baseline. It could also anchor the valuation in current earnings instead of book value. This valuation method is usually synonymous with the Residual Earnings Growth Model.
