Conversely, as the market’s expectations decrease, or demand for an option diminishes, implied volatility will decrease. Options containing lower levels of implied volatility will result in cheaper option prices. This is important because the rise and fall of implied volatility will determine how expensive or cheap time value is to the option, which can, in turn, affect the success of an options trade. As discussed in previous articles, implied volatility is the level of volatility that explains the market price of an option.
