Drivers of the Option Contract Value

  • The underlying stock‘s volatility: Volatility measures how uncertain we are about future price movements. The higher the stock volatility, the greater the value of the option. As volatility increases, the chance of stock appreciating or depreciating increases.Time to Maturity: The more time left to expiration, the greater the values of options. The longer maturity option is valuable as compared to a shorter maturity contract.The direction of underlying stock: If the stock appreciates, it will positively impact the call option and negatively impact put options. If the stock falls, it will have the opposite effect.Risk-free rate: As the interest rate increases, the expected return required by investors tends to increase.
