Tracking SDRL historical volatility helps you see how much Seadrill Ltd'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, Seadrill Ltd's HV tells you what really happened. Use our scanner to monitor SDRL 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 SDRL 30 day historical volatility is one of the most widely watched readings because it balances responsiveness with stability. Comparing Seadrill Ltd'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.

Seadrill Limited provides offshore contract drilling services to the oil and gas industry worldwide. It operates in three segments: Harsh Environment, Floaters, and Jack-ups Rigs. The company owns and operates drillships, semi-submersible rigs, and jack-up rigs for operations in shallow and ultra-deep-water in benign and harsh environments. It offers operation support and management services to third parties, as well as related and non-related companies.
