What is the Cost of Equity?
The cost of equity is the return expected by shareholders for committing their capital to the company and bearing market risks. The shareholders take significant risks because the returns on their holdings depend on the company’s performance and market movements.
Unlike debt holders who get a fixed interest payment, shareholders do not have a fixed return. Therefore, from the investor’s point of view, the cost of equity is the return an investor expects to receive in exchange for investing in the company’s equity share capital. From the company’s point of view, it is the minimum return the business is expected to generate to meet shareholders’ return expectations.
How is the Cost of Equity Calculated?
There are a few ways to calculate the cost of equity. They are mentioned below.
- Capital Asset Pricing Model (CAPM): The Capital Asset Pricing Model is widely recognized as a reliable method for determining the required return on equity. The formula for calculating CAPM is:
Cost of equity(Re) = Rf+ Beta × (Rm – Rf)
Where,
Rf = This represents the risk-free rate of return that investors can earn from risk-free investments such as government bonds.
B = This is the beta that represents the measure of volatility of a stock compared to the market movement.
Rm = This represents the expected return from the overall equity market. The difference between Rm and Rf is called the market risk premium.
- Dividend Capitalisation Method (Gordon Growth Model): This method is suitable for companies that are consistent with dividend payments.
Cost of equity = DPS / CMP + GRD
Where,
DPS = This is the expected dividend per share that the company has to pay next year
CMP = This is the current market price of one share
GRD = This is the growth rate at which dividends are expected to grow annually
Real-World Example: Cost of Equity in Action
Let’s understand the concept of the cost of equity with the help of examples.
Scenario 1: Using the CAPM method
A new investor, Mr G, is looking to invest in a large bank.He wants to evaluate the minimum return he should expect in exchange for taking the investment risk.
Here are the given details,
Risk-free rate of return (Rf) = 8%
Beta (B) = 1.1
Market rate of return (Rm) = 14%
Therefore, the cost of equity (Re)
= 8% + 1.1( 14% – 8%)
= 8% + 1.1 (6%)
= 8% + 6.6% = 14.6%
Hence, the estimated rate of return that Mr G shall expect from the bank is 14.6%.
Scenario 2: Using the Gordon Growth Model
An experienced investor, Miss K, has retired recently. She is interested in investing in a well-known company that provides consistent dividends.
Here are the provided details
Expected Dividend per share = ₹12
Current market price per share = ₹240
Dividend growth rate = 4%
Therefore, the cost of equity
= (12 / 240) + 4%
= 5% + 4%
= 9%
Hence, the estimated rate of return Miss K shall expect is 9%, based on the future growth rate and the expected dividend per share.
Why is the Cost of Equity important for Traders and Investors?
For investors and traders, the cost of equity is a key factor in assessing the potential risk and return of an investment. A few of them are mentioned below.
- Setting minimum return benchmark: The cost of equity estimates the minimum rate the return on the company’s stock that investors can compare with the risk associated with it to determine whether the investment offers adequate compensation for the risk involved.
- Evaluating corporate health: If a company generates more than the cost of equity, it represents good performance and efficient management. But if the cost of equity is higher than the actual returns, it may have a negative impact on the company’s equity holders.
- Assessing risk and reward: By assessing the cost of equity, investors can gain a clearer understanding of the return required to compensate for the risks associated with a company’s stock. Higher risk indicates a high cost of equity and estimates the balance between potential return and risk exposure.
- Gauging industry and market risk: The cost of equity of multiple companies or industries may help the traders to compare the risk associated with different sectors or markets. This helps the investors to choose the companies and industries that satisfy their financial expectations and match their risk tolerance.
Common Mistakes Beginners Make
Many investors make a few mistakes while evaluating the cost of equity. Some of them are mentioned below.
- Focusing only on returns: Many investors solely focus on the returns or dividends on a company’s stock. They ignore the risk associated with it and make investments without evaluating if the return compensates for the risk involved.
- Ignoring Beta: investors often ignore the impact of volatility on the stock of a company. A high beta indicates frequent movement in the market, making it riskier than it appears to be.
- Ignoring market conditions: Changes in economic and market conditions often lead to variations in market volatility. Even minor events can trigger considerable fluctuations in a company’s stock value. The factors can be the introduction of new policies, government regulations, geopolitical events, etc.
- Outdated data: Using outdated data to calculate the cost of equity and evaluate the risks and returns on a stock may cause misunderstandings in the future. The market price, beta, and risk-free rates can change over time.
How to use the Cost of Equity in your Investment Strategy?
The cost of equity is an essential tool to evaluate investment strategies.
- Set your required return benchmark: Use the cost of equity as the standard of your return and evaluate if your stock earns more than the cost of equity or less than that. A high cost of equity indicates that investors expect greater returns to compensate for the additional risk involved.
- Understand the WACC: The weighted average cost of capital (WACC) is the average rate of return that a company must earn to compensate both its shareholders and debt providers for the capital they have invested. It helps to determine the company’s overall valuation.
- Evaluate corporate management: If the return on the stock is higher than the cost of equity, then it indicates that the company is utilising the shareholders’ investment efficiently and also effectively managing the risks.
- Review changes over time: The cost of equity changes due to various factors such as industry and market conditions, company performance, and interest rate changes. Periodically reviewing the changes and updating the cost of equity helps investors to re-evaluate the portfolio and adjust their expectations.
Final Thoughts
The cost of equity is the standard rate of return that the company needs to generate to return to its stockholders. It provides useful insights into assessing the risks associated with and the potential returns on a company’s stock. Companies calculate the cost of equity to determine whether they are generating enough returns to keep their investors satisfied. On the other hand, investors calculate the cost of equity to evaluate whether the returns they earn are adequate for the risk borne.
Understanding the cost of equity helps investors to make informed and effective decisions. It helps them to set return benchmarks, assess risk and returns, and evaluate the overall valuation of the company. It also provides necessary insights for incorporating into their investment strategies and building a well-informed investment portfolio.
FAQs
A good cost of equity depends on the company, sector and market conditions. A lower cost of equity usually signals lower perceived risk, while a higher cost of equity means investors demand a higher return for taking additional risk.
No, the cost of equity is the minimum rate of return investors need to make the investment. On the other hand, ROI is the actual return earned on an investment.
Beta is the measure of a stock’s sensitivity to market movement. A higher beta indicates increased movement in the market condition and impacts the cost of equity because investors expect higher returns for additional risks.
It is unusual to have a negative cost of equity. But under unusual market conditions, calculations may show negative results due to the impact of changing market conditions.
The cost of equity is the expected rate of return on a company’s stock. On the other hand, the cost of capital includes the overall equity and debt of a company.
The short-term market traders focus mostly on the price movements and technical indicators. Understanding the cost of equity will provide them with insights into the long-term valuations and risk profiles for more informed investment decisions.
