Implied Volatility
What Is Implied Volatility?
Implied volatility is a measure used in options trading to estimate how much the market expects the price of an underlying asset to move in the future. It is derived from the price of an options contract rather than from historical price movements.
Higher implied volatility indicates that traders expect larger price swings.
Why It Matters
Implied volatility plays a critical role in options pricing. When volatility expectations increase, option prices generally rise because there is a greater chance the option will become profitable.
Traders monitor implied volatility to evaluate risk and potential opportunity.
How Implied Volatility Works
Implied volatility is calculated using options pricing models.
Key influences include:
- expected market movement
- demand for options contracts
- upcoming news or events
- investor sentiment
Options with higher implied volatility typically have higher premiums.
Example
Before a major earnings announcement, implied volatility for a company’s stock options may increase because traders expect large price movements.
Implied Volatility vs Historical Volatility
- Implied volatility reflects expected future volatility.
- Historical volatility measures past price fluctuations.
