Option Pricing Volatility

Option Pricing Volatility is an unknown factor in options pricing models. When estimating future pricing volatility, traders look at the historical volatility of a stock. Option pricing volatility happens when an option is priced cheaper for a stock that is not making wide swings than it is for a stock making more volatile swings. However, even for a stock that is not making volatile swings, traders must have expectations of option pricing volatility to come in the event a stock makes news that would upset the pricing.

Option Pricing Volatility - Assumptions

Options analysts usually focus on option pricing volatility assumptions model. Stock prices are considered to be unchanged, and this assumption is because stock prices incorporate all available information they cannot be predicted. However, trends do occur and option pricing volatility results in movement in the underlying stock’s price. The trader will get a much larger gain given the option pricing volatility.

Option Pricing Volatility - Impact

In option pricing volatility, a small percentage jump in volatility can lead to a larger gain in options prices. If this happens, a trader has a big edge in focusing on stock price changes compared to volatility change. As a result, traders will find more value in focusing on the expected stock price and the bigger the trend the bigger the edge in option pricing volatility.

Option Pricing Volatility - Adjustments

Since option pricing volatility can make a trader too optimistic, there are adjustments that can be made for a comfort level. In option pricing volatility there are two ways to do this: conservatively, traders can but an expiration date farther along than they think they will need, or buy one strike further in the money. Option pricing volatility always means traders will be faced with being wrong, but it is always better to be more conservative in option pricing volatility.

Option Pricing Volatility - Expiration

Option pricing volatility happens because unlike a stock, an option has an expiration date. Because of this, options have time values. A time value is the amount an investor is willing to pay, hoping that the value will increase before expiration. Market conditions can work to an investor’s benefit, because of option pricing volatility.

Option Pricing Volatility – Dividends

Option pricing volatility is affected by the underlying dividends and interest rates. The premiums are usually affected by “cost of carry” of shares which results in option pricing volatility.
