A call premium is the amount by which the price of a call option exceeds the intrinsic value of the underlying asset. The intrinsic value is the difference between the strike price and the underlying asset's price. The premium also includes the time value, which is the amount by which the option's price exceeds its intrinsic value.

How is call premium calculated? When you buy a call option, you are paying a premium (the price of the option) for the right to buy the underlying asset at a future date. The premium is calculated based on a number of factors, including the current price of the underlying asset, the strike price of the option, the time to expiration, the volatility of the underlying asset, and the interest rate. What causes a call option premium to fall? There are several reasons why a call option premium might fall. One reason is simply that the underlying asset has decreased in value. If the underlying asset is a stock, for example, and the stock price falls, then the call option premium will also fall.

Another reason why a call option premium might fall is because of changes in the implied volatility of the underlying asset. Implied volatility is a measure of the expected volatility of the underlying asset, and it is one of the main factors that determines the price of an option. If the implied volatility of the underlying asset falls, then the call option premium will also fall.

Finally, changes in the interest rate environment can also cause the call option premium to fall. This is because the interest rate environment affects the "time value" of an option. The time value is the portion of the option premium that is attributable to the time remaining until the option expires. If interest rates rise, then the time value of an option will decrease, and the call option premium will fall.

### Who receives premium in call option?

In a call option, the holder (buyer) has the right, but not the obligation, to buy an underlying asset (usually a stock) at a specified price (the strike price) from the writer (seller) of the option. The holder pays the writer a premium for this right. If the stock price at expiration is above the strike price, the holder will exercise the option and buy the stock, and the writer will be assigned. The writer will then have to sell the stock to the holder at the strike price. If the stock price at expiration is below the strike price, the holder will not exercise the option and the writer will keep the premium. At what time option premium becomes zero? The option premium is the price of the option contract. The premium becomes zero when the option expires and is not exercised. Is a call option bullish or bearish? A call option is a bullish strategy because it gives the holder the right to buy the underlying asset at a set price. If the price of the underlying asset goes up, the option holder will make a profit.
