What is Average True Range (ATR)?

Average True Range (ATR) is a technical analysis indicator that measures market volatility by calculating the average range of price movements over a specified period, typically 14 days. Developed by J. Welles Wilder Jr. in 1978, ATR is particularly valuable for cannabis investors analyzing the notoriously volatile marijuana stock market. ATR calculates the "true range" for each trading period, which is the greatest of three values: the current high minus the current low, the absolute value of the current high minus the previous close, or the absolute value of the current low minus the previous close. The average of these true ranges over the specified period creates the ATR value. In cannabis markets, ATR serves multiple critical functions. Cannabis stocks like Tilray (TLRY), Canopy Growth (CGC), and Aurora Cannabis (ACB) frequently exhibit ATR values significantly higher than traditional blue-chip stocks, reflecting the sector's inherent volatility. For example, major cannabis stocks often show ATR values ranging from $0.50 to $3.00 or higher during periods of regulatory uncertainty or earnings announcements. Traders use ATR for position sizing, determining appropriate stop-loss levels, and identifying breakout potential. A rising ATR indicates increasing volatility, often preceding significant price movements, while a declining ATR suggests consolidation periods. Cannabis investors particularly benefit from ATR analysis given the sector's sensitivity to regulatory changes, such as state legalization announcements or federal policy shifts. ATR is measured in the same units as the stock price (dollars for US cannabis stocks), making it intuitive to interpret. Unlike percentage-based volatility measures, ATR provides absolute price movement expectations, helping traders set realistic profit targets and risk management parameters. **Disclaimer:** This information is for educational purposes only and does not constitute investment advice.
