Most commodity products have high price volatility. The ill-effects of that volatility can be limited through the use of price-risk management tools, offered by banks, brokers and exchanges. Metals, agricultural products and most energy products have for years had an active price risk management market. Commodity products linked to the forest products industry have recently joined this development.
A higher volatility means that a security's value can potentially be spread out over a larger range of values. This means that the price of the security can change dramatically over a short time period in either direction.
A lower volatility means that a security's value does not fluctuate dramatically, and tends to be more steady. One measure of the relative volatility of a particular stock to the market is its beta.
For example, a stock with a beta value of 1.
Conversely, a stock with a beta of. Calculating Volatility Volatility is often calculated using variance and standard deviation.
The standard deviation is the square root of the variance. To calculate variance, follow the five steps below. Find the mean of the data set.
This is divided by 10, because we have 10 numbers in our data set. Calculate the difference between each data value and the mean. This is often called deviation. Negative numbers are allowed.
Since we need each value, these calculation are frequently done in a spreadsheet. This will eliminate negative values. Add the squared deviations together. In our example, this equals This is a measure of risk, and shows how values are spread out around the average price. It gives traders an idea of how far the price may deviate from the average.
Therefore, all the values do not fall within three standard deviations. Despite this limitation, standard deviation is still frequently used by traders, as price data sets often contain up and down movements, which resemble more of a random distribution.Managing extreme price volatility Building world-class capabilities in commodity risk management.
