Think of a call option as a down-payment for a future purchase.
A potential homeowner sees a new development going up. That person may want the right to purchase a home in the future, but will only want to exercise that right once certain developments around the area are built. The potential home buyer would benefit from the option of buying or not. Well, they can—you know it as a non-refundable deposit.
The potential home buyer needs to contribute a down-payment to lock in that right. With respect to an option, this cost is known as the premium. It is the price of the option contract.
This is one year past the expiration of this option. Now the home buyer must pay the market price because the contract has expired. Now, think of a put option as an insurance policy. The policy has a face value and gives the insurance holder protection in the event the home is damaged. What if, instead of a home, your asset was a stock or index investment? There are four things you can do with options:. Buying stock gives you a long position. Buying a call option gives you a potential long position in the underlying stock.
Short-selling a stock gives you a short position. Selling a naked or uncovered call gives you a potential short position in the underlying stock. Buying a put option gives you a potential short position in the underlying stock.
Selling a naked or unmarried put gives you a potential long position in the underlying stock. Keeping these four scenarios straight is crucial. People who buy options are called holders and those who sell options are called writers of options. Here is the important distinction between holders and writers:.
Speculation is a wager on future price direction. A speculator might think the price of a stock will go up, perhaps based on fundamental analysis or technical analysis. A speculator might buy the stock or buy a call option on the stock. Speculating with a call option—instead of buying the stock outright—is attractive to some traders since options provide leverage. Options were really invented for hedging purposes. Hedging with options is meant to reduce risk at a reasonable cost. Here, we can think of using options like an insurance policy. Just as you insure your house or car, options can be used to insure your investments against a downturn.
Imagine that you want to buy technology stocks. But you also want to limit losses. By using put options, you could limit your downside risk and enjoy all the upside in a cost-effective way. For short sellers , call options can be used to limit losses if the underlying price moves against their trade—especially during a short squeeze.
In terms of valuing option contracts, it is essentially all about determining the probabilities of future price events. The more likely something is to occur, the more expensive an option would be that profits from that event. For instance, a call value goes up as the stock underlying goes up. This is the key to understanding the relative value of options. The less time there is until expiry, the less value an option will have.
This is because the chances of a price move in the underlying stock diminish as we draw closer to expiry. This is why an option is a wasting asset.
Since time is a component to the price of an option, a one-month option is going to be less valuable than a three-month option. This is because with more time available, the probability of a price move in your favor increases, and vice versa. Accordingly, the same option strike that expires in a year will cost more than the same strike for one month. This wasting feature of options is a result of time decay. Volatility also increases the price of an option. This is because uncertainty pushes the odds of an outcome higher.
If the volatility of the underlying asset increases, larger price swings increase the possibilities of substantial moves both up and down. Greater price swings will increase the chances of an event occurring. Therefore, the greater the volatility, the greater the price of the option. Options trading and volatility are intrinsically linked to each other in this way. On most U. The majority of the time, holders choose to take their profits by trading out closing out their position. This means that option holders sell their options in the market, and writers buy their positions back to close.
Fluctuations in option prices can be explained by intrinsic value and extrinsic value , which is also known as time value. An option's premium is the combination of its intrinsic value and time value. Intrinsic value is the in-the-money amount of an options contract, which, for a call option, is the amount above the strike price that the stock is trading. Time value represents the added value an investor has to pay for an option above the intrinsic value.
This is the extrinsic value or time value. So, the price of the option in our example can be thought of as the following:. In real life, options almost always trade at some level above their intrinsic value, because the probability of an event occurring is never absolutely zero, even if it is highly unlikely. American options can be exercised at any time between the date of purchase and the expiration date.
European options are different from American options in that they can only be exercised at the end of their lives on their expiration date. The distinction between American and European options has nothing to do with geography, only with early exercise. Many options on stock indexes are of the European type.
Covered Call. With. Bull Call Spread.
Because the right to exercise early has some value, an American option typically carries a higher premium than an otherwise identical European option. This is because the early exercise feature is desirable and commands a premium. There are also exotic options , which are exotic because there might be a variation on the payoff profiles from the plain vanilla options.
Or they can become totally different products all together with "optionality" embedded in them. For example, binary options have a simple payoff structure that is determined if the payoff event happens regardless of the degree. Other types of exotic options include knock-out, knock-in, barrier options, lookback options, Asian options , and Bermudan options.
Again, exotic options are typically for professional derivatives traders. Options can also be categorized by their duration. Short-term options are those that expire generally within a year. Long-term options with expirations greater than a year are classified as long-term equity anticipation securities or LEAPs.
LEAPS are identical to regular options, they just have longer durations. Options can also be distinguished by when their expiration date falls. Sets of options now expire weekly on each Friday, at the end of the month, or even on a daily basis. Index and ETF options also sometimes offer quarterly expiries. More and more traders are finding option data through online sources. While each source has its own format for presenting the data, the key components generally include the following variables:. The simplest options position is a long call or put by itself.
This position profits if the price of the underlying rises falls , and your downside is limited to loss of the option premium spent. This position pays off if the underlying price rises or falls dramatically; however, if the price remains relatively stable, you lose premium on both the call and the put.
You would enter this strategy if you expect a large move in the stock but are not sure which direction. Basically, you need the stock to have a move outside of a range. A similar strategy betting on an outsized move in the securities when you expect high volatility uncertainty is to buy a call and buy a put with different strikes and the same expiration—known as a strangle. A strangle requires larger price moves in either direction to profit but is also less expensive than a straddle. Below is an explanation of straddles from my Options for Beginners course:. Spreads use two or more options positions of the same class.
