Tracking RARE historical volatility helps you see how much Ultragenyx Pharmaceutical 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.

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 RARE 30 day historical volatility is one of the most widely watched readings because it balances responsiveness with stability. Comparing Ultragenyx Pharmaceutical 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.
