Introduction:
Options trading is the buying or selling of contracts that give the holder the right, but not the obligation, to trade an underlying asset—usually a stock, index, or commodity—at a predetermined price before a set expiration date. The price paid for acquiring this right is known as the “premium.” Options contracts fall into two broad categories: calls and puts. A “call” option allows the buyer to buy the asset at a stated price, whereas a “put” option allows the right to sell it. The premiums of these options—call and put premiums—are a reflection of the cost and value of each contract and are affected by several factors that investors need to know to make informed trading decisions. This paper tries to discuss call and put premiums, their determinants, and their relevance in options trading.
What Is a Call Premium?
The call premium is the price which the buyer pays for call options, giving him/her the right to buy a given underlying asset at a previously agreed “strike price” within an agreed period. This essentially means the potential future value of the asset to the buyer. When the market price of the asset is higher than the strike price, then the benefit is obtained by the buyer as he can buy that asset at a lower cost. For example, an investor buys a calling option with the strike price being $5, along with the premium at that point of time. Later if asset price rises up to $60, the buyer might exercise that option, which means buy the asset, since his asset is being sold to him at $50. And now, he will have an extra $10 other than paying for the cost of his premium.
The call premium is another term for the probability that the asset price will exceed the strike and is fairly sensitive to all variables, including underlying asset price, time to expiration, volatility, and interest rates. If premiums are larger, the manifestation typically shows in higher volatility or farther-out expiration periods since these both increase the value of holding an option.
What is a Put Premium?
A put premium, in other words, is what a put option costs one, giving the buyer of this option the right to sell an asset at the struck price within a specified time. This premium is golden for the buyer when she believes that the asset’s price might drop. If the asset price has fallen below the strike price, then, the buyer can sell this asset at the higher striking price and make a gain on the difference. For instance, for the above example, the investor will pay a put option for $5 over a $50 strike stock and loses to the assets whose price goes to $40. One would then be selling at the $50 strike, realizing a $10 per share profit minus that premium.
The put premium, as in the call premium, depends on among others current price of the underlying asset, volatility, and the remaining life of an option in years, although time is calculated in periods as with a call premium. When there are increased chances that the call option is exercised profitably due to increased volatility or a very long period remaining before option expiration, higher premiums become evident.
Factors Impacting the Premiums on Call and Put Options:
Intrinsic Value: This is the amount by which the current price of an asset is above the strike price. An option that is “in the money” is one which is favourable to the option holder, and it has an intrinsic value. For example, a call option is in the money when the current price is more than the strike price; otherwise, a put option is in the money if the current price is lower than the strike price.
Time Value: The more extensive the length of an option before its expiration date, the longer there is time for the underlying asset to move upwards to a profit level. Option premiums generally tend to be more costly for longer-expired options.
Volatility: More significant moves in prices reflect greater volatility. And, by being so much more probable, that means there’s that much greater a likelihood the option is in the money. This would, of course, have the impact of setting up the requirement that assets exhibiting more significant levels of volatility generally possess greater levels of option premiums.
Interest Rates: Generally, call premiums are increased and put premiums decreased as the interest rate increases, as they affect the carrying cost of the underlying asset and the opportunity cost of holding cash.
Conclusion:
Call and put premiums should be understood well by options traders since they both cost and are potential profits for holding an options contract. The analysis of intrinsic value, time value, volatility, and interest rates give traders a sense of premiums they are willing to pay and the risks they would take. Whether investors look forward to capitalizing on rising or falling asset prices, understanding the dynamics of call and put premiums can certainly enhance their ability to handle the complex world of options trading.
