Is Alpha and Beta a risk indicator?
Both Alpha and Beta are backwards-looking risk indicators. This means that all calculations are based on the past data, and past performance is no guarantee of he future results. Therefore, they cannot always differentiate between relatively good and poor investments.
What is risk management?
Risk management is a crucial process used to make investment decisions. The process involves identifying and analyzing the amount of risk involved in an investment, and either accepting that risk or mitigating it. Some common measures of risk include standard deviation, beta, value at risk (VaR), and conditional value at risk (CVaR).
What is systematic risk?
Systematic risk is associated with the market. This risk affects the overall market of the security. It is unpredictable and undiversifiable; however, the risk can be mitigated through hedging. For example, political upheaval is a systematic risk that can affect multiple financial markets, such as the bond, stock, and currency markets. An investor can hedge against this sort of risk by buying put options in the market itself.
What is the second category of risk?
The second category of risk, unsystematic risk, is associated with a company or sector. It is also known as diversifiable risk and can be mitigated through asset diversification. This risk is only inherent to a specific stock or industry. If an investor buys an oil stock, he assumes the risk associated with both the oil industry and the company itself.
What is standard deviation in investing?
It indicates how much the current return is deviating from its expected historical normal returns. For example, a stock that has high standard deviation experiences higher volatility, and therefore, a higher level of risk is associated with the stock.
What is conditional value at risk?
Conditional value at risk (CVaR) is another risk measure used to assess the tail risk of an investment. Used as an extension to the VaR, the CVaR assesses the likelihood, with a certain degree of confidence, that there will be a break in the VaR; it seeks to assess what happens to investment beyond its maximum loss threshold. This measure is more sensitive to events that happen in the tail end of a distribution —the tail risk. For example, suppose a risk manager believes the average loss on an investment is $10 million for the worst one percent of possible outcomes for a portfolio. Therefore, the CVaR, or expected shortfall, is $10 million for the one percent tail.
What is risk return trade off?
One of the principles of investing is the risk-return trade-off, where a greater degree of risk is supposed to be compensated by a higher expected return. Risk - or the probability of a loss - can be measured using statistical methods that are historical predictors of investment risk and volatility.
What is the R squared measure?
R-squared is a statistical measure that represents the percentage of a fund portfolio or a security's movements that can be explained by movements in a benchmark index. For fixed-income securities and bond funds, the benchmark is the U.S. Treasury Bill. The S&P 500 Index is the benchmark for equities and equity funds .

What is standard deviation in investment?

As it relates to investments, the standard deviation measures how much return on investment is deviating from the expected normal or average returns.
What is Sharpe ratio?
The Sharpe ratio measures performance as adjusted by the associated risks. This is done by removing the rate of return on a risk-free investment, such as a U.S. Treasury Bond, from the experienced rate of return.
Standard Deviation
Sharpe Ratio
- The Sharpe ratiomeasures investment performance by considering associated risks. To calculate the Sharpe ratio, the risk-free rate of return is removed from the overall expected return of an investment. The remaining return is then divided by the associated investment’s standard deviation. The result is a ratio that compares the return specific to an investment with the associ…
Beta
- Beta measures the amount of systematic risk an individual security or sectorhas relative to the entire stock market. The market is always the beta benchmark an investment is compared to, and the market always has a beta of one. If a security's beta is equal to one, the security has exactly the same volatility profile as the broad market. A security...
Value at Risk
- Value at Risk (VaR)is a statistical measurement used to assess the level of risk associated with a portfolio or company. The VaR measures the maximum potential loss with a degree of confidence for a specified period. For example, suppose a portfolio of investments has a one-year 10% VaR of $5 million. Therefore, the portfolio has a 10% chance of losing $5 million over a one-year period. …
