Stem Inc (STEM) Historical Volatility

Tracking STEM historical volatility helps you see how much Stem 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.

Use our scanner to monitor STEM 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 STEM 30 day historical volatility is one of the most widely watched readings because it balances responsiveness with stability. Comparing Stem 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.
