Options Volatility
How implied volatility affects premiums, strategy selection, and event risk.
Volatility is central to options pricing
Historical volatility describes realized movement over a selected period. Implied volatility is derived from market prices and reflects the volatility input consistent with those prices under a model.
Why it matters
Higher implied volatility generally corresponds with higher option premiums when other inputs are unchanged. A trader can be directionally correct and still lose if the option was expensive, time passed, or implied volatility fell sharply.
Event risk
Earnings announcements, regulatory decisions, economic releases, and company news can produce large price gaps and sharp changes in implied volatility. Define the maximum loss and understand expiration timing before participating around an event.
