However, with your new-found knowledge of option volatility, you now have an advantage over 95% of the other participants in the market. When you open the spreadsheet, simply update the formulas in the yellow cells – namely stock price, Implied Volatility and the expiry date. The Black Scholes model relies on a normal distribution, which is one of its limitations. As you can probably deduce, a stock with a high Implied Volatility is expected to have large swings in price, while a stock with low volatility is expected to have small swings.
What Does one Standard Deviation Mean?
Euro, a forward-looking and subjective measure, differs from historical volatility because the latter is calculated from known past returns of a security. To understand where implied volatility stands in terms of the underlying, implied volatility rank is used to understand its implied volatility from a one-year high and low IV. Volatility measures the range of change in a stock’s price over a given period, and implied volatility is used by investors to forecast the future performance of a stock. Companies with high volatility see greater swings in their stock prices, compared with low-volatility companies that are generally more stable. Implied volatility is a vital concept for investors who trade in stock options, as they use it to judge if an option is fairly priced. An implied volatility ratio is one of several ways to evaluate option prices.
The implied volatility ratio is derived by dividing an option’s implied volatility with its historical volatility, with a ratio of 1.0 being a fair price. An option with a ratio of 1.2 is overpriced and selling at 20 percent more than its value, while an option with a 0.7 ratio is 30 percent undervalued and a bargain for an option buyer. If the market has a view that the future price movements of the asset will be small, then option prices and therefore the corresponding implied volatility figure will be lower. If the market has a view that the future price movements of the asset will be large, then option prices and therefore implied volatility will be higher.

How does VIX affect option price?
A price chart of the S&P 500 and the implied volatility index (VIX) for options that trade on the S&P 500 shows there is an inverse relationship. As Figure 1 demonstrates, when the price of the S&P 500 (top plot) is moving lower, implied volatility (lower plot) is moving higher, and vice versa.
A one standard deviation move to the upside would put the stock at $120, and to the downside, at $80. Thirty days later, when the 14% rise drops out of the calculation, the Historical Volatility comes back down to more normal levels. This is a very common occurrence with stocks, and often occurs in the lead-up to earnings announcements. With the spreadsheet you can alter the volatility rate, and then calculate the new call and put values. These days you never have to calculate out the Black Scholes formula manually.

This past January, for example, implied volatilities for Tesla were almost double historical volatilities. This occurred during a period when share prices increased from $400 to $700/share, and implied volatility was signaling a fear of a sharp price drop .

However, historical volatilities are only part of the picture, and any trader who is only aware of historical volatility is like a driver who is only looking out the back window.

There are many different types of volatility, but options traders tend to focus on historical and implied volatilities.
