How to tell if a stock is overvalued or undervalued using CAPM?
A critical aspect of CAPM is the concept of undervalued and overvalued securities. If the rate of return is greater than the expected return, it would be considered an overvalued security. If the rate of return is less than expected returns, it would be regarded as undervalued security.
CAPM is the Required (Intrinsic Value) Return. You compare your results from the CAPM with the Expected Return E®. If CAPM requires 10% and you are Expected to return 9%, the stock is overvalued and you do not buy. and vice versa.
Price-earnings ratio (P/E)
A high P/E ratio could mean the stocks are overvalued. Therefore, it could be useful to compare competitor companies' P/E ratios to find out if the stocks you're looking to trade are overvalued. P/E ratio is calculated by dividing the market value per share by the earnings per share (EPS).
How is CAPM calculated? To calculate the value of a stock using CAPM, multiply the volatility, known as “beta,” by the additional compensation for incurring risk, known as the “Market Risk Premium,” then add the risk-free rate to that value.
- β = 0: No Market Sensitivity.
- β < 1: Low Market Sensitivity.
- β = 1: Same as Market (Neutral)
- β > 1: High Market Sensitivity.
- β < 0: Negative Market Sensitivity.
Price-to-earnings ratio (P/E)
A company's P/E ratio is the most popular way to measure its value. In essence, it shows how much you'd have to spend to make $1 in profit. A low P/E ratio could mean the stocks are undervalued. P/E ratio is calculated by dividing the price per share by the earnings per share (EPS).
CAPM is a formula used to calculate the cost of equity—the rate of return a company pays to equity investors. For companies that pay dividends, the dividend capitalization model can be used to calculate the cost of equity.
When a stock is overvalued, it presents an opportunity to go “short” by selling its shares. When a stock is undervalued, it presents an opportunity to go “long” by buying its shares. Hedge funds and accredited investors sometimes use a combination of short and long positions to play under/overvalued stocks.
Key Takeaways. The P/E ratio is calculated by dividing the market value price per share by the company's earnings per share. A high P/E ratio can mean that a stock's price is high relative to earnings and possibly overvalued. A low P/E ratio might indicate that the current stock price is low relative to earnings.
An undervalued stock is defined as a stock that is selling at a price significantly below what is assumed to be its intrinsic value. For example, if a stock is selling for $50, but it is worth $100 based on predictable future cash flows, then it is an undervalued stock.
What is the CAPM model of valuation?
The capital asset pricing model (CAPM) is an idealized portrayal of how financial markets price securities and thereby determine expected returns on capital investments. The model provides a methodology for quantifying risk and translating that risk into estimates of expected return on equity.
The CAPM is a widely-used return model that is easily calculated and stress-tested. It is criticized for its unrealistic assumptions. Despite these criticisms, the CAPM provides a more useful outcome than either the DDM or the WACC models in many situations.
Unlike many analysts who use CAPM or capital asset pricing model (which is a whole other story that we will discuss sometime later), Buffett simply uses a long-term government bond rate. That's it, he makes it as simple as that.
Generally speaking, higher expected rates of return indicate higher risk, while lower expected rates of return indicate lower risk. To illustrate the use of CAPM, consider a hypothetical stock ACME Corp. trading on the U.S. equity market with a beta of 1.2.
Interpret the CAPM, II
When the covariance is negative, the beta is negative and the expected return is lower than the risk-free rate. A negative-beta asset requires an unusually low expected return because when it is added to a well-diversified portfolio, it reduces the overall portfolio risk.

What Is "Overvalued"? An overvalued stock has a current price that is not justified by its earnings outlook, known as profit projections, or its price-earnings (P/E) ratio. Consequently, analysts and other economic experts expect the price to drop eventually.
Relative Strength Index (RSI)
This indicator determines the strength of a stock on a scale of 0 to 100. The values above 70 are considered as overbought and values below 30 as oversold.
Advantages of the CAPM
It is generally seen as a much better method of calculating the cost of equity than the dividend growth model (DGM) in that it explicitly considers a company's level of systematic risk relative to the stock market as a whole.
CAPM helps understand the dividend yield of a stock. What are some of the core assumptions made by the Capital Asset Pricing Model (CAPM)? The core assumptions include same time horizon for all investments, investors are risk-seekers, and there are high taxes and transaction costs.
Can you use CAPM to calculate WACC?
“So, combining the two, you can use CAPM to calculate the cost of equity, then use that to calculate WACC by adding the cost of debt, usually the tax-effected average interest for all of the company's debt.” Identify your path to CFO success by taking our CFO Readiness Assessmentᵀᴹ.
Overvalued stocks tend to have stock prices that are more than 50 times the forecasted earnings. In most cases, you can look at the price per earnings-to-growth (PEG) ratio and dividend-adjusted PEG ratio. These numbers can provide a true stock value that you can compare to the current price.
It is arguable that a PE of five or less is not a remarkable bargain. While it might look as if the company's prospects are being viewed too negatively, it is not a bad rule of thumb to filter out companies with a PE below this level.
Fair Value Estimate for Apple
With its 2-star rating, we believe Apple's stock is overvalued compared with our long-term fair value estimate of $160 per share.
A high P/E ratio for a fast-growing company may make a lot of sense, so it's important to understand the growth outlook before making a judgment solely based on the P/E ratio. A PEG ratio above 2 is typically considered expensive, while a ratio below 1 may indicate a good deal.
