The assumptions underlying the CAPM's development are as follows, taken fromIntermediate Financial Managementthe Ninth Edition, by Eugene F. Brigham and Phillip R. Davis:
1. All investors focus on a single holding period, and they seek to maximize the expected utility of their terminal wealth by choosing among alternative portfolios on the basis of each portfolio's expected return and standard deviation.
2. All investors can borrow or lend an unlimited amount at a given risk-free rate of interest and there are no restrictions on short sales of any assets.
3. All investors have identical estimated of the expected returns, variances, and covariances among all assets (that is, investors have homogeneous expectations).
4. All assets are perfectly divisible and perfectly liquid (that is, marketable at the going price).
5. There are no transaction costs.
6. There are no taxes.
7. All investors are price takers (that is, all investors assume that their own buying and selling activity will not affect stock prices).
8. The quantities of all assets are given and fixed.

What are some examples of CAPM questions that test understanding of the Capital Asset Pricing Model?
Some examples of CAPM questions that test understanding of the Capital Asset Pricing Model include: Explain the concept of systematic risk and how it is measured in the CAPM. Calculate the expected return on a stock using the CAPM formula. Discuss the assumptions underlying the CAPM and their implications for its applicability in real-world scenarios. Compare and contrast the CAPM with other models used to estimate the expected return on an investment. Analyze a scenario and determine whether a stock is undervalued or overvalued based on its expected return calculated using the CAPM.
What is empirical evidence of CAPM?
Empirical evidence of the Capital Asset Pricing Model (CAPM) includes studies that have found a positive relationship between the expected return on an asset and its beta, as predicted by the model. However, empirical studies have also highlighted challenges such as the presence of anomalies that do not fit with the CAPM's assumptions, casting doubt on its ability to fully explain asset pricing in all market conditions.

What is the difference between Harry Markowitz model and CAPM model?
Markowitz is a normative theory while CAPM is a positive theory.
What are the advantages of CAPM?
The Capital Asset Pricing Model (CAPM) provides several advantages, including its simplicity and ease of use for estimating the expected return of an asset based on its systematic risk, measured by beta. It helps investors understand the relationship between risk and return, allowing for informed investment decisions. Additionally, CAPM facilitates the assessment of portfolio performance and aids in capital budgeting by providing a benchmark for evaluating investment opportunities. However, while useful, it relies on assumptions that may not always hold true in real-world markets.
What are the different methods of share valuation which do not use capm?
The present stock value evaluation is one of the methods of share valuation which does not use CAPM.
Assumptions of CAPM?
Investors care about mean and variance of returns only.They have homogeneous expectations.They have identical investment horizons.There is unlimited borrowing and lending at the risk-free rate.All assets are marketable.Unlimited short sales are allowed.Investors are price takers.There are no taxes and no transaction costs.Assets are perfectly divisible.
Why do financial managers have some difficulty applying capm?
Financial managers often face challenges in applying the Capital Asset Pricing Model (CAPM) due to its reliance on several assumptions that may not hold true in real-world markets, such as the existence of a risk-free rate and a perfectly diversified portfolio. Moreover, estimating the market risk premium and beta can be complex and subjective, leading to potential inaccuracies in the model's outputs. Additionally, CAPM assumes that investors have a single-period investment horizon and make decisions based solely on risk and return, which may not reflect the multifaceted nature of investor behavior. These limitations can hinder effective decision-making in financial management.
When was CAPM developed?
Harry Markowitz established the foundation of modern portfolio theory in 1952. The CAPM was developed twelve years later in articles by William Sharpe, John Lintner, and Jan Mossin.

What is the CAPM formula?
CAPM: kj = krf + B (market risk premium) = krf + B (km + krf) Note: B is Greek letter beta, which is the relationship between market returns and your portfolio.
