Implied volatility represents the market’s expectation of how much an asset’s price may fluctuate in the future. Rather than analysing past price movement, it is derived from option prices and reflects the collective outlook of traders on potential price swings. In simple terms, the implied volatility denotes how uncertain or confident the market feels about an asset’s near-term behaviour. When demand for options increases, premiums rise, and implied volatility moves higher. This does not indicate whether prices will go up or down. It only signals that traders expect larger movements. Conversely, when markets appear stable and predictable, option demand eases and implied volatility declines.
Implied volatility options, this measure plays a central role in pricing. Options become more expensive when implied volatility is high and cheaper when it is low, even if the underlying price remains unchanged. As it captures expectations rather than outcomes, implied volatility helps you understand risk, sentiment, and option valuation more clearly. Implied volatility changes continuously throughout the trading session.
