The measure of the percentage amount of share price correlation during the period with a selected group of peer companies. Pair-wise correlations with selected peers is calculated as the correlation between each pair and the sum of correlations divided by the number of pairs to produce the average correlation between each pair. No definition available.

- Definition
The measure of the percentage amount by which a share price fluctuates during a period for peer companies - maximum range. Volatility also may be defined as a probability-weighted measure of the dispersion of returns about the mean. The volatility of a share price is the standard deviation of the continuously compounded rates of return on the share over a specified period. That is the same as the standard deviation of the differences in the natural logarithms of the stock prices plus dividends, if any, over the period. No definition available.
