Price Range. The high and low prices between which a security trades over a given period of time. The size of the price range is an indicator of volatility, with a large price range showing a great deal of volatility and a low range showing the opposite. A price range is also called simply a range.
In the example, the average price is $75.80 /2 = $37.90. Subtract the minimum value from maximum one to calculate the range. In this example, the range is $41.12 - $34.68 = $6.44. Divide the range by the average value, and then multiply the result by 100 to calculate the relative percent range.
