Understanding Stock Volatility

Stock volatility measures how much the price of a stock fluctuates over time. Higher volatility means the stock price moves more dramatically over a given period, while lower volatility indicates a more stable price.

The annualized volatility calculated by this tool represents the standard deviation of daily returns, scaled to show what the expected annual risk would be if the daily behavior were to continue unchanged throughout the year.

Interpreting Results

  • Low Volatility (e.g., below 20%): The stock price is relatively stable with predictable movements
  • Medium Volatility (e.g., 20-30%): The stock has moderate price fluctuations
  • High Volatility (e.g., above 30%): The stock price is highly unpredictable with large price swings

Note: This calculator uses simulated daily returns for demonstration purposes. For real-world analysis, you should use actual historical price data.
