This implied volatility does not have to be calculated by the trader, since most option trading platforms provide it for each option listed. It is axiomatic that traders should buy low implied volatility and sell high implied volatility. But selling options with low implied volatility means accepting low returns on call writes, which cannot be considered good risk management if IV is out-of-line lower than historical volatility. Those writing portfolio stocks of course have no choice, since premium is what it is.

The intrinsic value is the difference between the https://forexaggregator.com/ asset’s price and the strike price. The intrinsic value of a call option is equal to the underlying price minus the strike price. A put option’s intrinsic value, on the other hand, is the strike price minus the underlying price. The time value, though, is the part of the premium attributable to the time left until the option contract expires. The time value is thus equal to the premium minus its intrinsic value.

If it goes ITM, you can use that $7 in premium to reduce my breakeven to $88 if I took the shares. There will always be a reason why some options yield higher premiums due to high implied volatility. It could be a product approval, or news about a merger or acquisition. Typically, just before earnings announcements, the IV will plateau; then, after the event, it’s most likely to drop and revert to its mean.

Options traders try to predict an asset’s future volatility, so the price of an option in the market reflects its implied volatility. However, implied volatility that is merely due to the normal statistical fluctuation of supply and demand for a particular option may be used to increase profits or decrease losses, especially for an option spread.
