The difference between the low and high prices for a security or index over a specific time period. Range defines the price spread for a defined period, such as a day or year, and indicates the security’s price volatility. The more volatile the security or index, the wider the range. The range expands over greater time periods; a security’s daily range will generally be smaller than its 52-week range, which in turn will be tighter than its five-year or 10-year range. Technical analysts closely follow ranges since they are very useful in pinpointing entry and exit points for trades.
Also known as price range or trading range.
