The Capital Asset Pricing Model (CAPM) describes the relationship between systematic risk and expected return for assets, particularly stocks. CAPM is widely used throughout finance for pricing risky securities and generating expected returns for assets given the risk of those assets and cost of capital. 2:39.
The expected return of the stock based on the CAPM formula is 9.5%: The expected return of the CAPM formula is used to discount the expected dividends and capital appreciation of the stock over the expected holding period.
The international capital asset pricing model (CAPM) is a financial model that extends the concept of the CAPM to international investments. The consumption capital asset pricing model is an extension of the capital asset pricing model that focuses on a consumption beta instead of a market beta.

The Capital Asset Pricing Model (CAPM) is the product of a financial investment theory that reflects the relationship between risk and expected return. The model assumes a linear relationship. The Capital Asset Pricing Model is used to forecast returns that can be obtained with risk-bearing asset classes.
The goal of the CAPM formula is to evaluate whether a stock is fairly valued when its risk and the time value of money are compared to its expected return. For example, imagine an investor is contemplating a stock worth $100 per share today that pays a 3% annual dividend.
The major drawback of CAPM is it is difficult to determine a beta. This model of return calculation requires investors to calculate a beta value that reflects the security being invested in. It can be difficult and time-consuming to calculate an accurate beta value. In most cases, a proxy value for beta is used.
What Is Beta? Beta is a measure of the volatility—or systematic risk—of a security or portfolio compared to the market as a whole. Beta is used in the capital asset pricing model (CAPM), which describes the relationship between systematic risk and expected return for assets (usually stocks).
CAPM states that Investors make investment decisions based on risk and return. The return and risk are calculated by the variance and the mean of the portfolio. CAPM reinstates that rational investors discard their diversifiable risks or unsystematic risks.
The CAPM is based on the assumption that all investors have identical time horizon. The core of this assumption is that investors buy all the assets in their portfolios at one point of time and sell them at some undefined but common point in future.
CAPM assumptionsInvestors hold diversified portfolios. ... Single-period transaction horizon. ... Investors can borrow and lend at the risk-free rate of return. ... Perfect capital market.
Advantages of the CAPM Model The CAPM is a simple calculation that can be easily stress-tested to derive a range of possible outcomes to provide confidence around the required rates of return.
Investors use CAPM when they want to assess the fair value of a stock. So when the level of risk changes, or other factors in the market make an investment riskier, they will use the formula to help re-determine pricing and forecasting for expected returns.

Alpha and beta are two different parts of an equation used to explain the performance of stocks and investment funds. Beta is a measure of volatility relative to a benchmark, such as the S&P 500. Alpha is the excess return on an investment after adjusting for market-related volatility and random fluctuations.
Solve for the asset return using the CAPM formula: Risk-free rate + (beta_(market return-risk-free rate). Enter this into your spreadsheet in cell A4 as "=A1+(A2_(A3-A1))" to calculate the expected return for your investment. In the example, this results in a CAPM of 0.132, or 13.2 percent.
Modern financial theory rests on two assumptions: (1) securities markets are very competitive and efficient ( that is, relevant information about the companies is quickly and universally distributed and absorbed); (2) these markets are dominated by rational, risk-averse investors, who seek to maximize satisfaction from returns on their investments.
Despite these issues, the CAPM formula is still widely used because it is simple and allows for easy comparisons of investment alternatives. Including beta in the formula assumes that risk can be measured by a stock’s price volatility. However, price movements in both directions are not equally risky.
The beta of a potential investment is a measure of how much risk the investment will add to a portfolio that looks like the market. If a stock is riskier than the market, it will have a beta greater than one. If a stock has a beta of less than one, the formula assumes it will reduce the risk of a portfolio.
Using the CAPM to build a portfolio is supposed to help an investor manage their risk. If an investor were able to use the CAPM to perfectly optimize a portfolio’s return relative to risk, it would exist on a curve called the efficient frontier, as shown on the following graph.
The most serious critique of the CAPM is the assumption that future cash flows can be estimated for the discounting process. If an investor could estimate the future return of a stock with a high level of accuracy, the CAPM would not be necessary.
However, it is impossible to know whether a portfolio exists on the efficient frontier or not because future returns cannot be predicted. This trade-off between risk and return applies to the CAPM and the efficient frontier graph can be rearranged to illustrate the trade-off for individual assets.
The CAPM formula is used for calculating the expected returns of an asset. It is based on the idea of systematic risk (otherwise known as non-diversifiable risk) that investors need to be compensated for in the form of a risk premium.
Asset Class An asset class is a group of similar investment vehicles. They are typically traded in the same financial markets and subject to the same rules and regulations. . Put another way, the more volatile a market or an asset class is, the higher the market risk premium will be.
Market Risk Premium The market risk premium is the additional return an investor expects from holding a risky market portfolio instead of risk-free assets. . A risk premium is a rate of return greater than the risk-free rate. When investing, investors desire a higher risk premium when taking on more risky investments.
The beta (denoted as “Ba” in the CAPM formula) is a measure of a stock’s risk (volatility of returns) reflected by measuring the fluctuation of its price changes relative to the overall market. In other words, it is the stock’s sensitivity to market risk.
