Implied Volatility, Definition
Implied volatility is a forward-looking metric that’s designed to gauge how volatile the market may be in the future. This measure of volatility doesn’t predict whether the price of a stock, or any other type of security, will move up or down.
What Implied Volatility Tells Investors
If you’re looking at the stock market in general, then implied volatility is often used as a guide for tracking bullish and bearish swings. When investor sentiment leans toward an increase in prices, then implied volatility may decrease as the market turns bullish.
Implied Volatility and Options
Implied volatility is most often used by options traders and is determined using option pricing models. If you trade options and understand how to read implied volatility, then you can use that information to choose entry or exit points for trades.
How to Calculate Implied Volatility
As mentioned, implied volatility is calculated using an option pricing model. One option is the Black-Scholes model, which factors in current market price of a stock, options strike price, time to expiration and risk-free interest rates. While there is a specific formula for this model, it can be complicated to follow and there’s no room for error.
Using Implied Volatility for Options Trading
Implied volatility is not a magic crystal ball, though it can give you some insight into how the market as a whole views a particular security. When using implied volatility to trade stocks or options, there are other things to consider as well, including:
The Bottom Line
Implied volatility is an important concept to understand if you trade options or plan to add that to your investment repertoire. While implied volatility is not necessarily an exact predictor of stock price movements, it can serve a purpose in helping you make more informed decisions about when to enter or exit an options trade.
Tips for Investing
Consider talking to a financial advisor about how to use implied volatility when making investment decisions. If you don’t have a financial advisor yet, finding one doesn’t have to be complicated.
