What Is Implied Volatility (IV) and Why Does It Matter in Options Trading?
Implied Volatility (IV) is one of the most important concepts in options trading. Unlike price movement, which reflects what has already happened, Implied Volatility represents the market's expectation of future price fluctuations. Professional traders monitor IV closely because it has a direct impact on option premiums, trading opportunities and risk management decisions.
What Is Implied Volatility?
Implied Volatility is the market's estimate of how much the price of an underlying asset may fluctuate over a future period. It is derived from option prices rather than calculated directly from past price movements. Higher IV generally reflects expectations of larger price swings, while lower IV indicates expectations of relatively stable market conditions.
