Key Learning Points: Lesson 8
- Variation of a parameter such as price data is an important factor in risk management.
- A commodity with high price variation is considered a high risk investment.
- Volatility is a term for measuring the dispersion and variation.
- Standard deviation can be used as a measure of volatility.
- The moving standard deviation is the standard deviation calculated for a moving window of data.
- One measure for calculating volatility is the moving (rolling) standard deviation for the changes of price (return).
- Price change can be calculated using an arithmetic method or using the natural log method (return).
- Exponentially weighted volatility uses a decay factor, λ, to apply higher weights to the more recent data.
- Relative Volatility Index is another measure of volatility.
- Correlation is a measure of the strength of the linear relationship between two quantitative variables.
- A strong correlation between spot and futures market prices makes the hedging efficient.
