IMPLIED VOLATILITY (IV)

Summary

Implied Volatility (IV) is like the market's crystal ball for predicting how much a stock's price will move up and down in the future. Unlike historical volatility which looks at past price movements, IV is forward-looking and is calculated backwards from current option prices. Think of it as the market's collective guess about how 'jumpy' or stable a stock will be. When IV is high, options are expensive because traders expect big price swings. When IV is low, options are cheaper because the market expects calmer price movements. It's expressed as a percentage and represents the expected annual price movement range.

Usage Context

Critical for understanding option pricing, developing trading strategies, assessing market sentiment, and making informed decisions about when to buy or sell options. Essential for topics covering option valuation models and risk management.

Common Confusions

• Thinking IV predicts price direction rather than price movement magnitude
• Confusing implied volatility with historical volatility
• Believing high IV always means options are overpriced
• Not understanding that IV can change independently of the underlying stock price
• Assuming IV remains constant until option expiration
