First Trust Natural Gas ETF (FCG) Historical Volatility

Tracking FCG historical volatility helps you see how much First Trust Natural Gas ETF's stock price has actually moved, giving you a baseline for whether option premiums look fair, cheap, or expensive. While implied volatility shows what the market expects, FCG's HV, also known as realized volatility, shows what actually happened.

Historical volatility is the annualized standard deviation of a stock's past returns, typically measured over rolling windows like 10, 20, 30, or 60 days. FCG's 30 day historical volatility, or FCG HV, is one of the most widely watched readings because it balances responsiveness with stability. Comparing FCG's HV to its implied volatility reveals the volatility risk premium. When IV sits well above HV, options are pricing in more movement than the stock has actually delivered, giving option sellers an edge. When HV runs hot relative to IV, options are pricing in less movement than the stock has delivered, and buyers may be underpaying for it.

The First Trust Natural Gas ETF is an exchange-traded fund. The investment objective of the Fund is to seek investment results that correspond generally to the price and yield, before fees and expenses, of an equity index called the ISE-Revere Natural Gas Index.
