La volatilità è uno degli elementi che concorrono a formare il prezzo di un opzione e/o covered warrant e può rivelarsi quello più difficile da “gestire” per chi non è un operatore esperto. Anche se rappresenta un elemento per la formazione del prezzo, molti traders covered warant. Infatti mentre la volatilità storica è un elemento conosciuto e statico, la volatilità implicita è a little size controllable, in fact they are a strategic element of volatility to operate on the market maker to vary the implied volatility with some discretion.
Volatility is a statistical indicator that measures the speed of movement of the market (in this case we speak of historical volatility, which is calculated on the basis of fluctuations in the past), the more unstable value of a security the greater the volatility, so it is basically a measurement of the intensity of the oscillations, but not its direction.
The implied volatility is an estimate on the intensity of future price fluctuations. The implied volatility is not related to the underlying, as is the case for the historical volatility, but an option to . The price of an option is calculated using a model (Black & Scholes), where there are values \u200b\u200bassociated with certain parameters, such as the underlying price, time to maturity, the interest rate and expected dividends.
