Study Notes
Value at Risk (VAR) Analysis
- Value at Risk (VaR) measures the potential loss in value of an investment or portfolio over a specific period.
- It provides a likely estimate of investment loss, based on market conditions.
- It's used to assess the financial risk in an investment portfolio over a defined time frame.
- Investors use VaR as a tool to calculate the number of assets they need to hold to offset potential losses.
Maximum Probable Loss
- Represents the maximum potential loss that could occur for a given period.
- Calculated based on past volatility of the investment.
- Determined for a specific confidence level, such as 95% or 99%.
Calculating VAR (Individual Investment)
- VAR = Daily Loss * Z Score * √Time in Days
- Daily Loss = Value of Investment * daily standard deviation
- Z Score values are based on the confidence level (example: 1.96 for 95% confidence; 2.33 for 99% confidence).
Portfolio Investment VAR
- VAR = Daily Loss * Z Score * √Time in Days
- Daily Loss = Value of Portfolio * standard deviation of portfolio OR
- Daily Loss = √(LA² + LB² + 2 * LA * LB* Correlation of AB), where LA is the daily loss of Security A, LB is the daily loss of Security B, and correlation of AB is their correlation.
Application of VAR
- Used to determine the maximum potential loss.
- Employed to create trading strategies in the stock market.
- Used in risk reporting and evaluating investment managers' performance.
- Helps in delegating risk-taking power.
Advantages of VAR
- Accessibility: It simplifies risk assessment.
- Common Usage: Frequently used in portfolio analysis, asset evaluation, and risk management.
- Relevance: Applicable to different investment instruments.
- Structured: Provides a structured way to present portfolio risk.
Disadvantages of VAR
- Application challenges in complex scenarios.
- Variable results from different calculation techniques.
- Security concerns due to the potential for inaccurate predictions.
- Portfolio analysis complexity from many assets.
Final Considerations
- VaR provides insights into potential losses for investments.
- It identifies potential outcomes, including worst-case scenarios.
- Users should account for time horizons when using VaR.
