Why does higher volatility mean higher prices?
Option pricing, the amount per share at which an option is traded, is affected by a number of factors including implied volatility. Implied volatility falls when the options market shows an upward trend. Higher implied volatility means a greater option price movement can be expected.
What causes the price of a call option to increase?
The value of calls and puts are affected by changes in the underlying stock price in a relatively straightforward manner. When the stock price goes up, calls should gain in value because you are able to buy the underlying asset at a lower price than where the market is, and puts should decrease.
How does volatility affect call option price?
An increase in the volatility of the stock increases the value of the call options and also of the put option. This rule applies to call options and to put options. Higher volatility means higher upside risk or higher downside risk. When there is downside risk, the buyer of the call option will forego the premium.
Why do higher interest rates lead to higher call option prices but lower put option prices?
With an increase in interest rates, shorting stock becomes more profitable than buying puts, as the former generates income and the latter does the opposite. Hence, put option prices are impacted negatively by increasing interest rates.

What factors affect the price of a call option?
Risk Factors Affecting Option Price The value of a call option is based on three factors: its strike price, its length and its volatility. By understanding how these factors combine, you can better predict whether a call option is worth buying.
Why does volatility affect option prices?
Unlike interest rates, volatility significantly affects the option prices. The higher the volatility of the underlying asset, the higher is the price for both call options and put options. This happens because higher volatility increases both the up potential and down potential.
Why do call options have positive rho?
Rho is the measure of an option’s sensitivity to interest rate changes. Rho is positive for purchased calls as higher interest rates increase call premiums. Conversely, Rho is negative for purchased puts as higher interest rates decrease put premiums.
Why do option prices increase with volatility?
Investors are always more willing to pay for safety rather than for volatility. But when it comes to call and put options, the scenario is entirely different. Calls and put options actually gain in value when the volatility in the market increases. So, let us understand why option prices increase with volatility.
Why are call options more valuable than put options?
When there is downside risk, the buyer of the call option will forego the premium. When there is upside risk, the buyer of the call option will rake in the profits. The same rule applies to put options too. That is why higher volatility makes call options and put options more valuable.
Does high volatility always mean a high price for call options?
High volatility just means the underlying stock is volatile, it does not imply if the stock is going up and down. But call options should go up in price only when the underlying stock goes up in price. So how come high volatility always means a high price for call option?
What happens to the premium on call options when the price falls?
The premium can decline dramatically due to the falling levels of implied volatility, counteracting the positive impact of a rise in price, leaving the unsuspecting call buyer miffed over why the price did not appreciate as anticipated. Figures 2 and 3 below demonstrate this disappointing dynamic using theoretical prices.
