Interest rate Dividends and risk-free interest rate have a lesser effect. Changes in the underlying security price can increase or decrease the value of an option.
These price changes have opposite effects on calls and puts.
Vega and Other Measures of Volatility
For instance, as the value of the underlying security rises, a call will generally increase. However, the value of a put will generally decrease in price. A decrease in the underlying security's value generally has the opposite effect.
The strike price determines whether an option has intrinsic value. An option's premium intrinsic value plus time value generally increases as the option becomes further in-the-money.

It decreases as the option becomes more deeply out-of-the-money. Time until expiration, as discussed above, affects the time value component of an option's premium.
Generally, as expiration approaches, the levels of an option's time value decrease or erode for both puts and calls. This effect is most noticeable with at-the-money options. The effect of implied volatility is subjective and difficult to quantify.

- Options on the euro dollar
It can significantly affect the time value portion of an option's premium. Volatility is a measure of risk uncertaintyor variability of price of an option's underlying security.
Major Factors Influencing Options Premium
Higher volatility estimates indicate greater expected fluctuations in either direction in underlying price levels. This expectation generally results in higher option premiums for puts and calls alike.
It is most noticeable with at-the-money options. The effect of an underlying security's dividends and the current risk-free interest rate has a small but measurable effect on option premiums.
Thus, the aim of this study was to propose and test a theoretical model showing the impacts of pricing policy on corporate profitability. To this end, companies in the metal-mechanic sector situated in the Northeast of Rio Grande do Sul State, Brazil were studied, integrating customer value-based pricing strategies, competition-based pricing strategies and cost-based pricing strategies with price levels high and low and performance with respect to profitability. The results indicate that the profitability of the surveyed companies is positively affected by value-based pricing strategy and high price levels while it is negatively affected by low price levels. Such findings indicate that pricing policies influence the profitability of organizations and therefore, a more strategic look at the pricing process may constitute one aspect that cannot be overlooked by managers. Los resultados indican que la rentabilidad de las empresas es afectada positivamente por la estrategia de precios basada en el valor y niveles de precios altos, y negativamente por los niveles de precios bajos.
This effect reflects the cost to carry shares in an underlying security. Cost of carry is the potential interest paid for margin or received from alternative investments such as a Treasury bill and the dividends from owning shares outright.
