Tracking WLDN historical volatility helps you see how much Willdan Group Inc's stock price has actually moved over past periods, giving you a baseline to judge whether current option premiums are fair, cheap, or expensive. While implied volatility tells you what the market expects, Willdan Group Inc's HV tells you what really happened. Use our scanner to monitor WLDN 30 day historical volatility alongside longer lookback windows and spot the moments when realized and implied diverge.
Historical volatility is the annualized standard deviation of an underlying's past returns, typically measured over rolling windows like 10, 20, 30, or 60 days. The WLDN 30 day historical volatility is one of the most widely watched readings because it balances responsiveness with stability. Comparing Willdan Group Inc's HV to its implied volatility reveals the volatility risk premium — when IV sits well above HV, option sellers tend to have an edge; when HV runs hot relative to IV, buyers may be underpaying for movement.
