How do you tell if a stock is undervalued using CAPM?
CAPM and the efficient frontier
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.
The sales per share metric is calculated by dividing a company's 12-month sales by the number of outstanding shares. A low P/S ratio in comparison to peers could suggest some undervaluation. A high P/S ratio would suggest overvaluation.
- 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.
A positive alpha would indicate a security has performed better than its expected return, while a negative alpha suggests it has underperformed. Therefore, overvalued securities should have a negative alpha, because their price is higher than justified by the predicted return, signaling potential overvaluation.
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.
An undervalued stock is defined as a stock that is selling at a price significantly below what is assumed to be its intrinsic value.
Low valuation ratios. One of the quickest ways to gauge whether a stock is undervalued is to compare its valuation ratios to the rest of its industry or the overall market. If the ratios are below that of the industry average or a broad market index such as the S&P 500, you may have a bargain on your hands.
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.
With investing, the higher the risk, the more an investor expects to earn. The capital asset pricing model (CAPM) tries to estimate how much you can expect to earn given the amount of risk.
What does it mean if CAPM is negative?

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.
The two-dimensional correlation between expected return and beta can be calculated through the CAPM formula and expressed graphically through a security market line, or SML. Any security plotted above the SML is interpreted as undervalued. A security below the line is overvalued.
When a security's current market price is approximately equal to its value estimate, the security is considered to be fairly valued. Conversely, when the market price exceeds the value estimate, the security is overvalued, and so the security is undervalued when the market price is lower than its estimated value.
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.
The capital asset pricing model (CAPM) calculates expected returns from an investment and can be used to determine prices for individual securities, such as stocks.
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.
Despite its limitations, CAPM can still be a useful tool for valuing a business, as long as it is applied with caution and sensitivity. To use CAPM in practice, one needs to estimate the three inputs: the risk-free rate, the market risk premium, and the beta of the asset.
if something is undervalued, it is considered to be less valuable or important than it really is: The water companies have a lot of undervalued assets. an undervalued business/company He specialises in making investments in small, undervalued companies.
Underpricing is the practice of listing an initial public offering (IPO) at a price below its real value in the stock market. When a new stock closes its first day of trading above the set IPO price, the stock is considered to have been underpriced.
Example of CAPM
367, which offer annual returns of 4%. Assuming that a beta factor of 1.1 is associated with this particular stock, one can calculate the expected dividend earnings by considering the risk-free premium as 3% and investor expectation of market appreciation by 7% annually.
What is better than CAPM?
The arbitrage pricing theory is an alternative to the CAPM that uses fewer assumptions and can be harder to implement than the CAPM. While both are useful, many investors prefer to use the CAPM, a one-factor model, over the more complicated APT, which requires users to quantify multiple factors.
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.
A positive alpha indicates the portfolio manager performed better than was expected based on the risk the manager took with the fund as measured by the fund's beta. A negative alpha means that the manager actually did worse than they should have given the required return of the portfolio.
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.
Conversely, the capital asset pricing model (CAPM) evaluates if an investment is fairly valued, given its risk and time value of money in relation to its anticipated return. Under this model, Cost of Equity = Risk-Free Rate of Return + Beta × (Market Rate of Return – Risk-Free Rate of Return).
