If markets are calm, volatility estimates are low, but during times of market stress, volatility estimates will be raised.

Implied Volatility

Implied volatility is a measurement of how much a security will move up or down in a specific time period. With stock options, this period will be the life of the contract (i.e., until the options contract expires). In order to be a successful option trader, you don’t just need to be good at picking the direction a stock will move (or won’t move), you also need to be good at predicting the timing of the move. Then, once you have made your forecasts, understanding implied volatility can help take the guesswork out of the potential price range on the stock.

Implied volatility is also the only variable that goes into a mathematical option pricing model. The most commonly traded options are in fact near-term, between 30 and 90 calendar days until expiration. So here’s a quick and dirty formula you can use to calculate a one standard deviation move over the lifespan of your option contract — no matter the time frame. The reason the options’ time value will change is because of changes in the perceived potential range of future price movement on the stock.

How To Measure Stock Market Sentiment With The Put

Does this mean standard deviation is not a valid tool to use while trading? If you use incorrect implied volatility in your calculation, the results could appear as if a move beyond a third standard deviation is common, when statistics tell us it’s usually not. With that disclaimer aside, knowing the potential move of a stock which is implied by the option’s price is an important piece of information for all option traders. All volatilities are quoted on an annualized basis , which means the market thinks the stock would most likely neither be below $40 or above $60 at the end of one year.
