Portfolio management is the process of , determining the appropriate asset allocation for the portfolio, and regularly monitoring and adjusting the portfolio as needed to ensure it continues to meet the investment objectives. Portfolio managers may also make decisions about buying and selling individual securities within the portfolio, in order to maintain the desired level of risk and return. The goal of portfolio management is to maximize returns while minimizing risk.
Security analysis is the process of evaluating the financial and investment potential of a company or security. This can include analyzing the company's financial statements, management, industry trends, and other factors to determine its value and potential for future growth. The goal of security analysis is to make informed investment decisions, whether that be buying, holding or selling a security.
Portfolio analysis is the process of evaluating the performance and risk of a collection of investments, known as a portfolio. This may include stocks, bonds, mutual funds, and other securities. The goal of portfolio analysis is to determine the overall performance of the portfolio and identify any potential issues or areas for improvement. This can help investors make more informed decisions about their investments and manage their portfolio effectively.
Traditional portfolio analysis is a method used to evaluate the performance and risk of a collection of investments, such as stocks, bonds, and other assets. It typically involves calculating various metrics, such as return, volatility, and diversification, to assess the overall performance of the portfolio and identify any potential issues. The most common techniques used in traditional portfolio analysis include modern portfolio theory (MPT) and the capital asset pricing model (CAPM). These methods can help investors make informed decisions about how to allocate their assets and manage risk.
MODERN PORTFOLIO ANALYSIS?
Modern Portfolio Theory (MPT) is a financial theory developed by Harry Markowitz in the 1950s. It suggests that investors can construct portfolios to optimize or maximize expected return based on a given level of market risk, emphasizing that risk is an inherent part of higher reward. Markowitz Model is a mathematical framework for assembling a portfolio of assets such that the expected return is maximized for a given level of risk. It uses historical returns and volatility of assets, as well as the correlation between assets, to calculate the optimal weightings of assets in a portfolio. The model is based on the assumption of rational investors and efficient markets.
The Markowitz model, also known as Modern Portfolio Theory (MPT), is a mathematical framework for constructing portfolios that aims to maximize returns for a given level of risk. Developed by Harry Markowitz in the 1950s, the model uses statistical techniques to determine the optimal combination of assets to include in a portfolio based on their expected returns and risk. The model also takes into account diversification, which helps to reduce overall portfolio risk by including assets that do not move in tandem with one another. MPT is widely used in finance as a tool for portfolio optimization and risk management.
10 assumption of markowitz model
1. Investors are rational and have similar expectations about future returns and risks.
2. Investors have identical investment horizons and risk preferences.
3. Investors have access to the same information and can accurately evaluate the risk and return of different assets.
4. Investment opportunities are independent and not correlated with each other.
5. The expected return and risk of an asset can be accurately measured and are known to investors.
6. Investors can borrow and lend at the risk-free rate.
7. Investors can buy and sell any proportion of any asset at no transaction costs.
8. The return of an asset is normally distributed.
9. Returns on all assets are defined in terms of the same currency.
10. The economy is in equilibrium and all markets are perfectly efficient.
The Markowitz model of portfolio diversification involves several key parameters, including:
1. Mean returns: The expected return for each asset in the portfolio, typically measured over a certain time period.
2. Variance: The degree to which the returns of an asset deviate from its mean return.
3. Standard deviation: A measure of the risk associated with an asset's returns, calculated as the square root of the variance.
4. Correlation: The degree to which the returns of two assets are related to each other.
5. Minimum variance portfolio: A portfolio that has the lowest possible risk, while still offering a target expected return.
6. Efficient frontier: A graphical representation of the trade-off between risk and return for different portfolio combinations.
7. Risk-free rate: The rate of return on a risk-free investment, such as a government bond.
8. Capital market line: A line that represents the trade-off between risk and return for portfolios that include a risk-free asset.
9. Tangency portfolio: A portfolio that is tangent to the efficient frontier and capital market line, providing the highest possible return for a given level of risk.
10. Optimal portfolio: The portfolio that provides the highest possible return for a given level of risk, or the lowest possible risk for a given level of return, depending on the investor's preferences.
Traditional portfolio theory, also known as Modern Portfolio Theory (MPT), is a framework for constructing portfolios that was developed by Harry Markowitz in the 1950s. MPT focuses on diversification and risk-return trade-offs, and it is based on several assumptions, such as that investors are rational and have similar expectations about future returns and risks, and that the return of an asset is normally distributed.
Model portfolio theory, on the other hand, is an extension of MPT that incorporates additional factors into the portfolio construction process. This can include factors such as macroeconomic conditions, market sentiment, and technical analysis.
While MPT is based on a mean-variance optimization framework, Model Portfolio Theory can be based on other optimization framework like Stochastic Dominance, Risk Parity, and others.
In traditional portfolio theory, the portfolio is constructed based on historical data and assumptions about future market conditions, while in model portfolio theory, the portfolio is constructed based on a combination of historical data, forward-looking analysis, and other factors that are believed to be relevant for the portfolio's performance.
In summary, Traditional Portfolio theory is a framework for constructing portfolios that focuses on diversification and risk-return trade-offs, while Model Portfolio theory is an extension of MPT that incorporates additional factors into the portfolio construction process, and can use other optimization framework.
portfolio construction
Portfolio construction is the process of selecting and managing a group of investments in order to achieve a specific investment goal. This process involves determining an appropriate asset allocation, selecting specific investments to fill that allocation, and regularly reviewing and adjusting the portfolio as needed. The goal of portfolio construction is to maximize returns while minimizing risk.
There are several approaches to portfolio construction, including:
Modern portfolio theory (MPT): Developed by Harry Markowitz in the 1950s, MPT is based on the idea that investors can construct portfolios that maximize returns for a given level of risk, or minimize risk for a given level of return.
1. Capital asset pricing model (CAPM): Developed by William Sharpe in the 1960s, CAPM is a model that helps investors determine the expected return of an investment based on the risk-free rate, the asset's beta (systematic risk), and the market's expected return.
2. Black- litterman model: Developed in the 1990s by Fischer Black and Robert Litterman, this model is an extension of MPT that incorporates investor views and subjective judgment into the portfolio construction process.
3. Mean-variance analysis: This approach involves analyzing the expected return and risk (as measured by the standard deviation of returns) of individual assets and portfolios.
4. Risk-parity: This approach aims to construct portfolios where each asset class has the same level of risk contribution.
5. Smart beta: This approach is based on the idea of using alternative index construction rules to weight the securities in a portfolio, in order to capture certain types of market inefficiencies.
6. Factor-based investing: This approach is based on the idea of identifying certain risk factors that are associated with higher returns, and constructing portfolios that have a high exposure to those factors.
Diversification is a risk management strategy that involves investing in a variety of different assets to spread out risk. The idea is that by investing in a diverse range of assets, an investor can potentially reduce the overall risk of their portfolio. Diversification can be achieved by investing in different types of securities, such as stocks, bonds, and real estate, or by investing in different sectors, industries, or geographic regions.
There are several benefits to diversification. Firstly, it can help to reduce overall portfolio risk by spreading investments across different assets. If one investment performs poorly, the others may offset the loss and provide more consistent returns over time. Secondly, diversification can increase the overall return on investment by providing exposure to different sectors or industries that may perform well in different economic conditions.
It's important to note that diversification is not a guarantee of a profit or protection against loss, and it's still important to conduct thorough research and analysis before making any investment decisions. Additionally, it's also important to keep in mind that diversification has limits and it's not possible to diversify away all of the risk in the portfolio and that diversification strategies may not protect against market risk.
10 importance of diversification in portfolio management
1. Reduces risk: Diversification helps to spread investment risk by allocating assets among a variety of investments, which reduces the risk of losing money due to the poor performance of a single investment.
2. Smooths returns: Diversification can help to smooth out returns over time, as different investments may perform well at different times.
3. Reduces volatility: By diversifying a portfolio, the overall volatility of the portfolio is reduced, making it less likely that an investor will have to sell investments at a loss.
4. Enhances returns: Diversifying across different asset classes, sectors, and geographies can help to enhance overall returns over time.
5. Mitigates specific risks: Diversification helps to mitigate specific risks such as currency risk, interest rate risk and country risk.
6. Helps to preserve capital: Diversification helps to preserve capital by spreading the risk across several investments, this can help to minimize the impact of any single investment that may perform poorly.
7. Increases chances of better returns: By diversifying across different types of investments, investors increase their chances of achieving better returns over time
8. Helps to achieve personal financial goals: Diversification helps an investor to achieve their personal financial goals by spreading the risk across different types of investments that align with their risk tolerance.
9. Protects against market downturns: Diversification can help protect against market downturns by spreading investments across different asset classes, sectors and geographies.
10. Helps to reduce emotional biases: Diversification can help to reduce emotional biases that may lead to impulsive investment decisions.
10 problems of diversification
1. Lack of focus: Diversification can lead to a lack of focus on core business activities, which can negatively impact performance.
2. Increased complexity: Diversifying a business often leads to increased complexity in terms of management, operations, and financing.
3. Higher costs: Diversifying a business can lead to higher costs associated with developing new products, entering new markets, and managing multiple business units.
4. Difficulty in managing multiple business units: Diversifying a business can make it difficult for management to effectively oversee and manage multiple business units.
5. Risk of over-diversification: A business that becomes too diversified may spread itself too thin, making it difficult to achieve success in any one area.
6. Difficulty in achieving economies of scale: Diversifying a business can make it difficult to achieve economies of scale, which can increase costs and decrease efficiency.
7. Difficulty in maintaining a consistent corporate culture: Diversifying a business can make it difficult to maintain a consistent corporate culture across multiple business units.
8. Difficulty in maintaining consistent branding: Diversifying a business can make it difficult to maintain consistent branding across multiple products or markets.
9. Difficulty in establishing a clear competitive advantage: Diversifying a business can make it difficult to establish a clear competitive advantage in any one area.
10. Difficulty in obtaining financing: Diversifying a business can make it more difficult to obtain financing as investors may view the business as more risky.
What is Time value of money
The time value of money (TVM) is a concept in finance that states that money in the present is worth more than the same amount of money in the future due to its potential earning capacity. This is because money can be invested and earn interest, so the longer the money is invested, the more it will be worth in the future. TVM is the basis for many financial calculations, such as the present value and future value of investments, the calculation of interest rates, and the determination of the optimal time to invest or borrow money.
Formula of time value of money
There are several formulas that are used to calculate the time value of money, depending on the specific situation.
Future Value (FV) formula: FV = PV (1 + r)^t, where PV is the present value, r is the interest rate, and t is the number of time periods.
Present Value (PV) formula: PV = FV / (1 + r)^t, where FV is the future value, r is the interest rate, and t is the number of time periods.
Annuity formula : PV = PMT [ (1 - (1 + r)^-n ) / r] where PV is the present value, PMT is the periodic payment, r is the interest rate, and n is the number of payments.
Annuity due formula : PV = PMT [ (1 - (1 + r)^-n ) / r]*(1+r) where PV is the present value, PMT is the periodic payment, r is the interest rate, and n is the number of payments.
Perpetuity formula : PV = C / r where PV is the present value, C is the constant cash flow, and r is the interest rate.
These formulas are used to calculate the value of money at a specific point in time, taking into account the effects of interest and inflation over time.
What is efficient frontier
The efficient frontier is a concept in modern portfolio theory that describes the relationship between risk and return for a given set of investments. It is a graph that plots the expected return of a portfolio against its standard deviation, which is a measure of risk.
The efficient frontier represents the set of portfolios that offer the highest expected return for a given level of risk, or the lowest level of risk for a given level of expected return. The portfolios that lie on the efficient frontier are considered to be "efficient" because they offer the best trade-off between risk and return.
The efficient frontier is determined by the individual investments that make up the portfolio and their respective risk and return characteristics. The efficient frontier can be shifted upward by adding more risky assets and downward by adding less risky assets. The optimal portfolio is the one that lies on the efficient frontier and has the highest expected return for the level of risk that the investor is willing to take.
The efficient frontier is also known as the Markowitz frontier, named after Harry Markowitz, who first developed the concept in the 1950s.
